Young onset dementia & learning disability

People with a learning disability are at increased risk of developing dementia as they age.  Figures show that one in ten people with a learning disability develop young onset Alzheimer’s disease between the age of 50 and 65.  People with Down's syndrome are more at risk of developing dementia from their mid-30’s onwards; with one in three people with Down's syndrome developing dementia in their 50s.  

Dementia is less likely to be detected in the early stages for people with a learning disability due to 'diagnostic overshadowing', meaning that a diagnosis is either given much later down the pathway, or even not at all.  Alternatively, a person’s learning disability could also lead to an inaccurate diagnosis being given - a person could be presumed to have dementia if for example, they are of a certain age and have Down’s syndrome, when in fact their symptoms could be another health condition.
