See the Traumatic Brain Injury (Adults) Evidence Map for summaries of the available research on this topic.
The scope of this page is limited to traumatic brain injury in adults (ages 18 years and older). For information about traumatic brain injury in children (ages birth through 21), see ASHA's Practice Portal page on Pediatric Traumatic Brain Injury.
Traumatic brain injury (TBI) is a form of nondegenerative acquired brain injury, resulting from an external physical force to the head (e.g., fall) or other mechanisms of displacement of the brain within the skull (e.g., blast injuries). Consistent with the diagnostic criteria detailed in the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5; American Psychiatric Association [APA], 2013), TBI is associated with one or more of the following characteristics:
TBI can cause brain damage that is focal (e.g., gunshot wound) or widespread (e.g., diffuse axonal injury sustained in a motor vehicle accident). Damage can result from a primary injury or a secondary injury (see common classifications of TBI for more details).
Severity of TBI is based on the extent and nature of the injury, duration of loss of consciousness, posttraumatic amnesia (PTA; loss of memory for events immediately following injury), and extent of confusion at initial assessment during the acute phase of the injury (APA, 2013; Centers for Disease Control and Prevention [CDC], 2015).
The Department of Defense (DOD) defines the following levels of severity (Defense Health Agency, 2019):
Incidence refers to the number of new cases identified in a specific time period.
Prevalence refers to the number of individuals who are living with TBI in a given time period.
Worldwide, in 2016, there were approximately 27 million new cases of TBI with an age-adjusted incidence rate of 369 per 100,000—representing a 3.6% increase from 1990. In the same year, prevalence was 55.5 million individuals, representing an 8.4% increase from 1990 (Global Burden of Disease [GBD], 2019). Each year, the number of new cases of TBI in the Unites States is approximately 2.8 million (CDC, 2015). These incidence rates include approximately 2.5 million TBI-related emergency department visits, 288,000 TBI-related hospitalizations, and 57,000 TBI-related deaths. Whereas age-adjusted rates of TBI-related ED visits increased by 54% over the span of 8 years (2006–2014), hospitalization rates decreased by 8% and death rates decreased by 6% (CDC, 2014).
According to the National Center for Injury Prevention and Control, an estimated cumulative 5.3 million individuals are living with a TBI-related disability in the United States. This represents a prevalence of approximately 2% of the U.S. population (CDC, 2015). Additional data suggest the prevalence of U.S. TBI-related disability after hospitalization to be 3.2 million (Zaloshnja, Miller, Langlois, & Selassie, 2008). Current studies estimate that approximately 775,000 older adults live with long-term disability associated with TBI (Zaloshnja et al., 2008).
Incidence and prevalence rates of TBI vary across clinical and epidemiological studies. These variations are often due to differences in participant characteristics (e.g., ages included), diagnostic classification criteria within and across subtypes (e.g., mild TBI vs. severe TBI), and sources of data (e.g., hospital admissions, emergency room visits, general practitioner visits). Moreover, current statistics do not consider individuals who do not seek medical care. Therefore, these estimates may significantly underestimate the incidence and prevalence of TBI.
The TBI prevalence in the general population is 16.7% among males and 8.5% among females. The odds of sustaining a TBI are 2.22 times higher in men than in women (Frost, Farrer, Primosch, & Hedges, 2012). Overall, males account for approximately 59% of all reported TBI-related medical visits in the United States (Faul, Xu, Wald, & Coronado, 2010).
As many as 75% of individuals who experience a TBI are diagnosed with mild TBI. This is likely an underestimate of the problem, as patients with mild TBI—who are often treated outside the hospital setting or are not treated at all—are not included in most estimates. In addition, this number includes only mild TBIs in the civilian population (CDC, 2003). It is believed that factors such as automobile safety, seatbelt use, helmet use, and better overall treatment for severe TBI in prehospital and hospital settings, while unable to prevent TBIs entirely, have mitigated the severity and thus mortality (Thurman et al., 1999).
Signs and symptoms of TBI vary, depending on the site and extent of injury to the brain, premorbid abilities, and functional domains affected (e.g., physical, cognitive, language, sensory). The effects of TBI can be temporary or permanent, and no two individuals present with the same pattern.
The clinician considers cultural differences that may lead to differences in presentation of certain cognitive measures (e.g., response time, self-monitoring, executive functioning). See ASHA's Practice Portal page on Cultural Competence for more information.

Cognitive control deficits have a unique impact on the linguistic abilities in bilingual and multilingual speakers (Ansaldo & Marcotte, 2007), especially in individuals with frontal lobe and subcortical lesions (Price, Green, & von Studnitz, 1999). The individual's premorbid proficiency in the languages they speak can influence their ability to maintain the target language.
In addition to language production errors found in monolingual speakers, bilingual and multilingual individuals with acquired brain injury may also demonstrate
Speech-language pathologists (SLPs) consider variations in narrative structures secondary to cultural and linguistic factors to ensure that a communication difference is not inaccurately diagnosed as a disorder.
The CDC (2019) identified the following leading causes:
Falls were the leading cause of hospitalizations among adults 55 years of age and older (CDC, 2014). Motor vehicle accidents were the leading cause of hospitalizations for adolescents and adults aged 15–44 years of age. Persons aged 15–24 years and 75 years and older are at highest risk of sustaining a TBI, with the most common causes attributed to motor vehicle crashes, falls, and violence (CDC, 2014; Faul et al., 2010).
Sports-related injuries and explosive blasts/military combat injuries are other leading causes of TBI. Acquiring a brain injury may predispose an individual to additional brain injuries before symptoms of the first have resolved completely; the second impact is more likely to cause brain swelling and widespread damage (Dessy, Rasouli, & Choudhri, 2015). See ASHA's resource on common classifications of TBI.
Speech-language pathologists (SLPs) play a central role in the screening, assessment, and treatment of persons with TBI. The professional roles and activities in speech-language pathology include clinical services (assessment, planning, and treatment), prevention, and advocacy, as well as education, administration, and research. See ASHA's Scope of Practice in Speech-Language Pathology (ASHA, 2016b).
Appropriate roles for SLPs include the following:
As indicated in the Code of Ethics (ASHA, 2016a), SLPs who serve this population should be specifically educated and appropriately trained to do so.
Audiologists play a central role in the assessment, diagnosis, and rehabilitation of hearing and vestibular deficits in individuals with TBI. See ASHA's Scope of Practice in Audiology (ASHA, 2018).
Appropriate roles for audiologists include the following:
As indicated in the Code of Ethics (ASHA, 2016a), audiologists who serve this population should be specifically educated and appropriately trained to do so.
Successful management of individuals with TBI typically requires collaboration and teaming with other professionals. For example, dysphagia management may include interdisciplinary teamwork between occupational therapists, dietitians, nursing staff, and the SLP. SLPs may also work with nursing staff (e.g., to facilitate communication between the individual and their medical team) and with physical therapists (e.g., to promote carryover and insight for current limitations and safety).
Interdisciplinary collaboration and teaming also form an integral part of audiology services to individuals with TBI. Audiologists consult and collaborate regularly with other professionals about the individual's communication management, accessibility to information, the vocational/educational implications of hearing loss and balance problems, and the legal implications of hearing loss and/or other auditory and vestibular dysfunction.
See ASHA's web page on interprofessional education/interprofessional practice (IPE/IPE) and ASHA's resource on collaboration and teaming.
SLPs and audiologists do not diagnose TBI. However, they need to understand the individual's medical assessment, physical condition, course of recovery, and nature of the neurological damage to guide development of an appropriate assessment plan (Hegde, 2018).
Assessment of individuals with TBI requires collaboration with the individual and their family members, medical professionals, rehabilitation specialists, and other professionals. Findings from the speech-language and audiology assessments are considered in the context of findings from other professionals on the team. See ASHA's web page on interprofessional education/interprofessional practice (IPE/IPP) and ASHA's resources on person- and family-centered care, and collaboration and teaming.
Assessments are conducted in the language(s) used by the person with TBI, with the use of translation/interpretation services as necessary. Assessments are sensitive to cultural and linguistic variables. See ASHA's Practice Portal pages on Bilingual Service Delivery and Cultural Competence, and Collaborating With Interpreters, Transliterators, and Translators.
See the Screening section of the Traumatic Brain Injury (Adults) Evidence Map for relevant evidence, expert opinion, and client/patient perspective.
Audiologists and SLPs conduct screening to identify possible deficits following a TBI. Screening is typically completed prior to conducting more comprehensive evaluations. Screening does not provide a detailed description of the severity and characteristics of deficits resulting from TBI but, rather, identifies the need for further assessment.
Hearing screening and otoscopic inspection for impacted cerumen occur prior to screening for other deficits. If the individual wears hearing aids, an audiologist should inspect the hearing aids to ensure that they are in working order, and the individual should wear the hearing aids during screening. Hearing screening is within the scope of practice for SLPs. See ASHA's Practice Portal page on Adult Hearing Screenings.
Referral for a full audiologic evaluation is necessary if the individual fails the hearing screening or if hearing loss is suspected. Audiologists may also screen for tinnitus and vestibular deficits as indicated. See ASHA's Practice Portal pages on Hearing Loss—Beyond Early Childhood, Tinnitus and Hyperacusis, and Balance System Disorders.
SLPs screen for speech, language, cognitive-communication, and swallowing deficits using appropriate standardized instruments or nonstandardized procedures. A referral is made for comprehensive assessment in one or more of these areas if the individual fails that portion of the screening.
The purpose of a comprehensive assessment for individuals with TBI is to determine speech, language, cognitive-communication, swallowing, and audiologic strengths and needs.
If an individual wears prescription eyeglasses or hearing aids, and prescriptions are still appropriate post injury, then he or she should wear the glasses or aids during assessment.
If the TBI resulted in additional hearing or visual deficits, then sensory aids and/or accommodations used before the injury may not be sufficient. Physical or environmental modifications may be needed (e.g., large-print material, modified lighting, amplification devices).
If changes to premorbid hearing and/or vision are significant, then the individual is referred for comprehensive audiologic and/or vision assessments prior to any additional testing. See the Assessment section of ASHA's Practice Portal page on Hearing Loss—Beyond Early Childhood.
Consistent with the World Health Organization's (WHO) International Classification of Functioning, Disability and Health (ICF) framework (ASHA, 2016b; WHO, 2001), ongoing comprehensive assessment of individuals with TBI is conducted to identify and describe the following:
See the ASHA resource titled Person-Centered Focus on Function: Traumatic Brain Injury [PDF] for an example of assessment data consistent with ICF.
Assessment protocols can include both standardized and nonstandardized tools and data sources. See ASHA's resource on assessment tools, techniques, and data sources. The decision to use standardized or nonstandardized tools is based upon a variety of factors, including the needs of the person with TBI, the complexity of impairment, payer rules, and facility policy.
Standardized Assessment—Currently, there are few standardized communication assessments for use with individuals TBI. When selecting a standardized assessment tool, clinicians consider
Tests that are too difficult for individuals with severe deficits will not yield useful information. In addition to selecting tests that assess the targeted areas of deficit, clinicians must also evaluate if the tests selected have been normed for use with TBI.
Nonstandardized Assessment—Functional nonstandardized assessments are particularly valuable because individuals with TBI often perform disproportionately better or worse in activities of daily living compared with abilities predicted by standardized test scores.
Nonstandardized assessment procedures serve a variety of purposes, including identifying
(Fausti, Wilmington, Gallun, Myers, & Henry, 2009; Wintrow, 2013)
Interdisciplinary collaboration is necessary to maximize the breadth and depth of skills tested and to ensure that the individual is not over-tested or subject to practice effects due to repeated exposure to the same or similar assessment tools.
Depression or anxiety—as a consequence of neurological damage or as a part of the post-traumatic stress disorder complex—can adversely affect test performance. If signs and symptoms of depression are present or suspected, the individual is referred to a neuropsychologist, clinical psychologist, or psychiatrist for follow-up.
The side effects of prescription drugs may affect test performance (e.g., due to excessive drowsiness). Polypharmacy—the concurrent use of several medications—is common among individuals with multiple medical conditions, and some medications may worsen cognitive problems worse.
Repetitive brain trauma contributes—along with other variables—to the development of chronic traumatic encephalopathy (CTE), which in turn influences overall cognitive and behavioral function and increases the risk for dementia (Stern et al., 2011). Therefore, consider the effects of repeated brain injury when determining prior level of function and baseline skill levels.
Periodic, ongoing assessment is important because neurological recovery can occur for several months or longer after some types of severe brain injury. Ongoing assessment can also be used to examine an individuals' responses to rehabilitation and to life after the injury.
The following factors may influence the assessment of cognitive-communication abilities in individuals with TBI:
Factors that can affect swallowing function following TBI include
See Murdoch and Theodoros (2001) for a summary of related research.
Consider the patient's level of arousal, cognitive status, and ability to follow commands throughout ongoing swallowing assessment. Depending on the individual's overall alertness and ability to participate, the clinical bedside examination may also include feeding trials of a variety of food textures and liquid consistencies.
Comorbidities—including memory and attention deficits, tinnitus, dizziness, and anxiety—can make it difficult to attribute auditory complaints to auditory-only processing deficits and may confound audiologic test results.
Balance is a multisensory function. Therefore, during vestibular assessment, “clinicians working with individuals with blast trauma need to consider several causes of postural instability, including TBI, orthostatic hypotension, cervical vertigo, visual deficits, possible side effects of ototoxic drugs, and vestibular pathology” (Fausti et al., 2009, p. 804).
When selecting assessment tests, the SLP considers the influence of cultural and linguistic factors on the individual's communication style and the potential impact of impairment on function.
Clinicians make appropriate accommodations and modifications to the testing process to reconcile cultural and linguistic variations. Comprehensive documentation includes descriptions of these accommodations and modifications. Scores from standardized tests are often invalidated in these cases and may not be appropriate to report. Rather than reporting scores, results can be stated descriptively (e.g., number and types of errors made on various assessment tasks.) See ASHA's Practice Portal pages on Bilingual Service Delivery; Collaborating With Interpreters, Transliterators, and Translators; and Cultural Competence.
Due to the complexity of cognitive sequelae in TBI and its influence on bilingual language production (Penn, Frankel, Watermeyer, & Russell, 2010), a thorough case history and interviews with the family and individual are particularly useful in identifying premorbid language proficiency, language preference for assessment and treatment of linguistic deficits, and communicative needs in the community (Lorenzen & Murray, 2008).
Treatment of persons with TBI considers
The goal of intervention in TBI is to achieve the highest level of independent function for participation in daily living. Consistent with the ICF framework (WHO, 2001), intervention is designed to
Interventions that enhance a patient's activity and participation through modification of contextual factors may be warranted, even if the prognosis for improved body structure/function is limited.
See ASHA's Person-Centered Focus on Function: Traumatic Brain Injury [PDF] for an example of goal setting consistent with ICF.
Person- and family-centered care is a collaborative approach grounded in a mutually beneficial partnership among individuals, families, and clinicians. Each party is equally important in the relationship, and each party respects the knowledge, skills, and experiences that the others bring to the process. This approach to care incorporates individual and family preferences and priorities and offers a range of services, including providing counseling and emotional support, providing information and resources, coordinating services, and teaching specific skills to facilitate communication.
Person- and family-centered care for individuals with TBI
See ASHA's resource on person- and family-centered care.
Treatment for TBI can be restorative and/or compensatory. These approaches are not mutually exclusive; aspects of more than one approach often are integrated into the delivery of services.
Restorative approaches involve direct therapy aimed at improving or restoring impaired function(s) through retraining. Treatment is often hierarchical, targeting specific processes in the impaired domain before introducing more demanding higher-level tasks, and eventually generalizing skills to more functional activities and tasks (Sohlberg & Mateer, 2001).
Compensatory approaches focus on adapting to deficits by learning new or different ways of doing things to minimize difficulties (National Institutes of Health [NIH], 1998). Compensatory approaches draw on the individual's strengths to maximize his or her abilities, often through the use of external or internal aids.
A compensatory approach to treatment may also include accommodations and/or modifications. Accommodations are changes to the environment, task, or mode of response that allow an individual to access and participate in an activity without changing the activity itself. Modifications are changes to the nature of an activity to facilitate participation and promote success in home, community, academic, and work settings.
The following are brief descriptions of both general and specific treatments for persons with cognitive-communication and swallowing disorders associated with TBI. This list is not exhaustive, and inclusion of any specific treatment approach does not imply endorsement by ASHA.
Augmentative and alternative communication (AAC) involves supplementing or replacing natural speech and/or writing with aided (e.g., pictures, line drawings, speech-generating devices, and tangible objects) and/or unaided (e.g., manual signs, gestures, and finger spelling) symbols. AAC may be temporary (e.g., used by patients postoperatively in intensive care) or permanent (e.g., used by an individual with a disability who will need to use some form of AAC throughout their lifetime).
Factors that influence selection and use of appropriate AAC systems following TBI include the individual's communication abilities and needs, as well as their cognitive, neurobehavioral, motor, sensory, and perceptual impairments. Individuals with TBI may rely on assistive technologies to compensate for their cognitive impairments in the absence of linguistic or motor speech disorders (Fried-Oken, Beukelman, & Hux, 2011).
See ASHA's Practice Portal page on Augmentative and Alternative Communication.
Cognitive-communication treatment may focus on restoring skills and/or compensating for deficits. Treatment can address discrete cognitive-communication domains (e.g., attention) or can focus more globally on functional communication.
Cognitive-communication treatments include the following:
Instructional or teaching techniques used in cognitive-communication treatment include the following:
Social communication interventions are designed (a) to improve functional conversational skills, including the use of appropriate pragmatic language norms (e.g., taking turns and remaining on topic) and (b) to help the individual with TBI navigate social situations.
Components of social communication intervention in adults with TBI include
Communication partner training (CPT) is an example of social communication intervention. The goal of CPT is to improve the communication effectiveness of individuals with TBI by training communication partners to use strategies such as
See also ASHA's Practice Portal page on Social Communication Disorder.
TBI can result in dysarthria and apraxia, as well as problems with respiration, phonation, and resonance. Intervention may focus on the individual speech subsystems of respiration, phonation, articulation, and velopharyngeal function or, more globally, on overall verbal communication function using behavioral and instrumental treatments, compensatory strategies, and/or environmental modifications.
The goal of dysphagia treatment is to support safe and efficient oral intake and to ensure adequate nutrition and hydration.
Considerations for dysphagia management in individuals with TBI include
Effective dysphagia management relies on the consistent implementation of compensatory strategies. Deficits in any of the areas noted above can have a negative impact on the success of treatment.
See ASHA's Practice Portal page on Adult Dysphagia.
Audiologists are integral to rehabilitation of hearing and balance deficits associated with TBI. Treatment for hearing loss includes selection and fitting of amplification devices and training in the use of assistive technologies (e.g., hearing assistive technology [HATS]).
The treatment goals for balance disorders associated with TBI are (a) to promote the central nervous system's natural compensation processes to reduce or eliminate symptoms, (b) to decrease the individual's sensitivity to symptom-provoking movements, and (c) to reduce the risk of falls.
Audiologists are also involved in the management of tinnitus associated with TBI. Management can include the use of hearing aids, sound masking, counseling, and cognitive-behavioral interventions.
Treatment for audiology-related symptoms may include counseling about the use of coping and compensatory skills that can minimize the effects of hearing and balance disorders and reduce safety risks.
See ASHA's Practice Portal pages on Hearing Loss—Beyond Early Childhood, Hearing Aids for Adults, Balance System Disorders, and Tinnitus and Hyperacusis. See also ASHA's resources titled Hearing Assistive Technology (HATS) and Audiology Information Series: Hearing Assistive Technology.
Treatment considers the cultural values and norms of the individual. Different dimensions of culture may influence an individual's views on seeking care and external support following a TBI (see ASHA's resource on examples of cultural dimensions). For example, some cultures may have a sense of shame or feel the need to hide a disability. This may influence how an individual and their family/caregivers approach treatment. See ASHA's Practice Portal page on Cultural Competence.
Treatment is also sensitive to linguistic diversity. It is provided in the language(s) used by the individual with TBI. See ASHA's Practice Portal pages on Bilingual Service Delivery and Collaborating With Interpreters, Transliterators, and Translators.
Individuals with persistent cognitive-communication deficits after a TBI may continue to face challenges as they return to work or academic settings and manage daily activities such as shopping and handling finances (e.g., Colantonio et al., 2004; Kennedy, Krause, & Turkstra, 2008; Meulenbroek, Bowers, & Turkstra, 2016; Meulenbroek & Turkstra, 2016).
The potential impact of persisting deficits highlights the need for continued support. The role of the SLP is to identify communication-related deficits, determine how they might affect the individual in various settings, and design treatment approaches to minimize the impact of these deficits.
The nature of deficits associated with TBI creates unique challenges in work settings. Fatigue, sensory issues, health concerns, and cognitive-communication deficits (e.g., language processing, reading and writing, verbal reasoning, memory, and pragmatics) can have a negative impact on performance (see, e.g., Meulenbroek et al., 2016; Meulenbroek & Turkstra, 2016).
The SLP identifies current cognitive-communication deficits, determines how these may affect life skills and job performance, and then trains the individual on strategies they can use to minimize the impact of the deficits in work settings (Bonelli, Ritter, & Kinsler, 2007). The SLP collaborates with counselors and psychologists, vocational rehabilitation specialists, job coaches, and employers, as appropriate, to help implement necessary accommodations for maximum outcomes.
Individuals with TBI may be eligible for protections in the workplace under Section 504 of the Rehabilitation Act of 1973. This law protects a qualified individual from discrimination based on their disability. Section 504 prohibits employment discrimination against individuals who meet job requirements and can perform essential job duties with or without reasonable accommodations. It may also provide vocational training and employment services for eligible individuals. SLPs can give input about reasonable accommodations to minimize the effects of cognitive-communication deficits. These include providing written task instructions and using time management devices to help the individual stay on task.
Attention, memory, learning, executive function, and social–emotional impairments—coupled with self-regulation challenges—place individuals with TBI at greater risk for failure in academic settings (Kennedy et al., 2008).
The SLP can provide support to individuals in college (and vocational training programs) by identifying systems and services to facilitate studying, learning, and time management, and by training individuals to use compensatory strategies and promoting self-advocacy (Kennedy & Krause, 2011; Turkstra, Gamazon-Waddell, & Evans, 2004; Volkers, 2015).
Disability support services staff may collaborate with SLPs to select courses, modify schedules, and implement accommodations (under Section 504 or similar plans, if applicable). Accommodations might include notetakers, extended time for tests and assignments, and assistive technology (e.g., text-to-speech and speech-to-text devices that help with reading and writing tasks).
In addition to determining the optimal treatment approaches for individuals with TBI, SLPs consider other service delivery variables—including format, provider, dosage, and timing—that may affect treatment outcomes.
Format is the structure of the treatment session (e.g., group vs. individual). Group therapy can provide individuals with TBI an opportunity to initiate social interaction in a structured environment with feedback from the clinician and peers. The combination of individual and group therapy is more effective in reaching functional goals than the group format alone (Tate et al., 2014).
Technology has been incorporated into the delivery of services for TBI, including the use of telepractice to deliver face-to-face services remotely. Videoconferencing and interactive skills-based programs via telepractice may be more meaningful for providing support and information to caregivers than self-guided web sessions (Rietdijk, Togher, & Power, 2012). Telepractice may allow clinicians to help patients practice skills in the context in which those skills will be used (Turkstra, Quinn-Padron, Johnson, Workinger, & Antoniotti, 2012). See ASHA's Practice Portal Page on Telepractice.
Provider refers to the person providing the treatment (e.g., SLP, trained volunteer, caregiver). Cognitive rehabilitation is most successful in the context of the individual's needs and current living environment. Family members and significant others play a critical role in supporting the individual with TBI and augmenting the treatment plan. Training that incorporates everyday communication partners may allow partners to facilitate carryover beyond the training sessions (Togher et al., 2014).
Dosage refers to the frequency, intensity, and duration of service. Clinicians consider the individual's arousal level and ability to tolerate therapy sessions, prognosis, stage in recovery, and frequency of other therapeutic activity when determining the appropriate frequency, intensity, and duration of services.
Timing refers to the timing of intervention relative to the injury. Treatment typically begins with assessment in the acute or rehabilitation inpatient setting and may continue in post-acute care (e.g., post-acute rehabilitation).
Setting refers to the location of treatment (e.g., home, community-based). Clinicians consider the individual's functional abilities and goals and how best to facilitate carryover when determining the most appropriate setting for intervention. Time-limited residential programs and community-based programs are available in some areas to foster community integration and provide peer support.
