The significance of dyslexia screening for the assessment of dementia in older people.

Dyslexia and Dementia are disorders that share cognitive impairments in attention, language, and working memory. It is therefore possible that the presence of dyslexia may influence the assessment of the severity of dementia and potentially lead to the development of atypical forms of dementia. The present study investigated the prevalence of problems suggestive of dyslexia with a brief self-report questionnaire in a sample of 195 older adults referred to a Memory Clinic for dementia assessment. Ten percent reported problems suggestive of dyslexia consistent with the estimated prevalence in the general population. This group performed significantly lower in a number of attention and language related tests but not in other cognitive domains. These results highlight the importance of dyslexia screening for the assessment of dementia, not least because the choice of treatment is guided by the outcome of the assessment of the severity and the type of dementia.
