Alzheimer’s disease is the most common cause of dementia, but there are many other diseases and conditions that can lead to dementia. These conditions are rarer, can occur at a younger age, and can cause symptoms that are not only memory-related. These include difficulties with vision, language, movement and behavioural changes.
Between 5% and 15% of people living with a dementia receive a diagnosis of a rare, inherited or young onset dementia. RDS provides support for 6 rare dementias. These are:
Posterior cortical atrophy (PCA)
Primary progressive aphasia (PPA)
Frontotemporal dementia (FTD)
Familial frontotemporal dementia (fFTD)
Familial Alzheimer’s disease (FAD)
Lewy body dementia (LBD)
