Dementia: posterior cortical atrophy (PCA)
If you have posterior cortical atrophy, tissue in your brain atrophies (shrinks) as cells are lost.
PCA can affect your visual processing, spelling, writing and arithmetic.
People often experience the first symptoms of posterior cortical atrophy in their mid-50s or early 60s. However, it can also affect older people.
