 Memory problems may occur later in the disease. Causes The most common cause of posterior cortical atrophy is a form of Alzheimer's disease that's not typical. It affects the back of the brain. Other less common causes include corticobasal degeneration, Lewy body dementia and Creutzfeldt-Jakob disease. Researchers are looking at potential gene variations that may be related to the condition. Risk factors Further study is needed to determine whether the risk factors for Alzheimer's disease may play a role in posterior cortical atrophy.
