What are the rare forms of dementia?

This post is on the rarer forms of dementia, which make up the minority of dementia diagnoses. These also include reversible and treatable dementias, such as those resulting from infectious diseases or nutrition deficiencies. As Alzheimer’s disease is the most commonly diagnosed form of dementia, it receives the majority of focus in awareness raising, research, and funding for treatment and prevention.

What is Posterior Cortical Atrophy (PCA)?

This information comes from Alzheimer’s Society, a wonderful organization based out of the UK. They are one of my go-to sources for information and I highly recommend taking a look around their website.

You can access the same article on their website as well as resources on dementia by clicking on the title, below.

The first symptoms of PCA tend to occur when people are in their mid-50s or early 60s. However, the first signs are often subtle and so it may be some time before a formal diagnosis is made.

Initially, people with PCA tend to have a relatively well-preserved memory but experience problems with their vision, such as difficulty recognising faces and objects in pictures. They may also have problems with literacy and numeracy. These tasks are controlled by the back part of the brain, where the initial damage in PCA occurs. Continue reading
