Disease: Posterior Cortical Atrophy
Symptoms: Posterior cortical atrophy symptoms vary among people. Symptoms also can vary over time. They tend to gradually get worse.

Judging how far away objects are. Using everyday objects or tools. Identifying left from right.  Other common symptoms include:  Anxiety. Confusion. Changes in behavior and personality.

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.
