Later stages of the disease
As the disease progresses, word finding, day-to-day memory and general cognitive functions may become affected. In the later stages of the disease, people with posterior cortical atrophy (PCA) may develop jerking movements of their limbs and occasionally seizures. Unfortunately as with typical Alzheimer’s disease, the condition is progressive with a gradual deterioration of skills and abilities over the years following diagnosis. The duration of the PCA condition is poorly understood, with some people living approximately the same length of time as individuals with typical Alzheimer’s disease (on average 10-12 years following the onset of symptoms) and others living with the condition for longer.
