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 7 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)
- Young-onset Alzheimer’s disease (YOAD)
The diagnosis of a rare dementia can bring with it a set of unique and complex challenges. Rare dementias are proportionately more likely to develop in individuals at a younger age (before 65 years old), raising challenges relating to individual and family transitions (e.g. work, retirement planning, childcare and care transitions).
Following diagnosis, many find that existing health, social and voluntary services do not cater adequately for their individual needs. More specifically, they may find that established dementia support groups are not particularly relevant to their situation. Members of these groups can often be significantly different to them in terms of age, life situation and symptoms.
30% of people living with a rare dementia initially receive an incorrect diagnosis and there is a widespread lack of understanding and a shortage of dedicated resources to support those affected. We are working together with people affected by rare dementias, to provide social, emotional and practical support alongside research and training about rare dementias. By increasing awareness about these conditions, we hope to empower communities to better support everyone affected by a rare dementia diagnosis.
