Hi. Have you ever been told that this or that relative has Alzheimer’s and or has Dementia and have you ever wondered what the difference between them. - Primary progressive aphasia

Primary progressive aphasia

Primary progressive aphasia (PPA) is a condition caused by damage to parts of the brain that control our personality, emotions, language and behaviour. In most cases, this damage is caused by frontotemporal dementia. Most people who develop PPA will be in their 50s and 60s.

PCA is caused by damage to the brain cells at the back of the brain that make sense of what our eyes are seeing.

Alzheimer’s disease is most often the cause of the brain cell damage in PCA. PCA is sometimes called a visual form of Alzheimer’s. However, the early signs of PCA and typical Alzheimer’s can be very different. Alzheimer’s disease usually affects memory first. In PCA the first signs are often problems with vision and perception.

People often develop PCA at an earlier age than typical Alzheimer’s disease, usually between the ages of 50 and 65. PCA is a less common form of dementia, and at the moment we can’t be sure how many people around the world are affected by it.
