The dementia that affects your vision
If you ask someone to name a symptom of dementia, chances are they would mention becoming forgetful or problems with memory. While these are the most well-known symptoms of Alzheimer’s, which is the most common cause of dementia, there are some more varied and lesser known symptoms that can affect things like vision, speech, personality and behaviour. What’s more, there are other forms of dementia in which these are the primary symptoms and where memory is relatively unaffected.
One of these other forms of dementia is posterior cortical atrophy (PCA), which is a rare subtype of Alzheimer’s disease. Find out more from Alzheimer’s Research UK
