Description: This is a meta-analysis of research studies addressing the ability of patients with Alzheimer's disease to accurately name living things and non-living things.
Question(s) Addressed:
Is anomia in Alzheimer's disease category specific in nature?
Does Alzheimer's disease differentially affect the ability to name living things and non-living things?
Population: Patients with Alzheimer's disease
Intervention/Assessment: Naming ability of non-living things and naming ability of living things.
Number of Studies Included: 21
Years Included: Any (published in 2007)

Naming
The results of this meta-analysis indicate that the impairment in lexical-semantics in patients with Alzheimer's disease significantly affects the naming of items in the living things (LT) and non-living things (NLT) domains.
There is no significant difference between naming of LT and naming of NLT; however, there appeared to be an effect of stimulus color. Color stimuli increases the level of impairment in naming living things.
