Down Syndrome - Onset Age of Dementia

Arvio Maria and Bjelogrlic-Laakso Nina M

Background: Alzheimer’s disease is the most common cause of death in people who have Down syndrome. This prospective, population-based, 15-year follow-up study aimed to define the onset age of dementia. Methods: At baseline 98 adults were screened for the first time by using the Present Psychiatric State-Learning Disabilities assessment. These screenings were repeated twice more during the study. Results: The indicative signs for dementia increased rapidly after the age of 35 and appeared most frequently as reduced self-care skills, loss of energy, impaired understanding and forgetfulness. Conclusion: Regular follow-up of people who have Down syndrome from the age of 30 onward enables appropriate interventions to delay the progression of dementia.
