What are the rarer types of dementia?
Alzheimer's disease is the most common cause of dementia, but there are many rarer diseases and conditions that can lead to dementia, dementia-like symptoms or mild cognitive impairment. Rarer forms of dementia account for only around 5 per cent of all dementia cases in the UK. This page outlines some of these rarer causes and gives some suggestions for where to go for more specialist advice and information.

- Normal pressure hydrocephalus (NPH)
- Parkinson's disease dementia (PDD)

Being told that you or a loved one has dementia can be very difficult and you may experience a range of different emotions as time goes on. Support is available if you need it. Alzheimer's Society's National Dementia Helpline (0300 222 11 22) can provide information, support, guidance and signposting to other organisations.
