Screening of dementia indicating signs in adults with intellectual disabilities

Abstract

<p><strong>Background: </strong>In intellectual disability, the cognitive delay is observed during developmental age, whereas in dementia, cognitive decline occurs during post-developmental period. So far, the risk of dementia in people with intellectual disability, excluding those with Down syndrome, is poorly known.</p><p><strong>Method: </strong>We screened dementia signs in a study group of 230 adults (34-80 years of age) with the help of the British Present Psychiatric State-Learning Disabilities assessment.</p><p><strong>Results: </strong>Of the study members, 42% showed two or more signs. The overall frequency of symptoms did not differ between age groups. The number of individuals with a genetic syndrome or disease manifesting with a shortened lifespan was greater in the younger age groups when compared to the older age groups.</p><p><strong>Conclusion: </strong>People with an intellectual disability represent numerous rare syndromes with comorbidities. It seems that dementia signs may affect any age groups of adults with intellectual disability.</p>
