Warning Symptoms Of Posterior Cortical Atrophy

Posterior cortical atrophy (Benson's syndrome) is a rare condition that is considered a variation of Alzheimer's disease. It is known as a visual variant, meaning it primarily affects an individual's vision, and it may impact cognitive function as it progresses as well. Approximately five percent of Alzheimer's disease patients have posterior cortical atrophy. In addition to Alzheimer's disease, posterior cortical atrophy may occur with Lewy body dementia and some other progressive neurological conditions. Typically, the first symptoms begin in patients in their fifties and sixties. Since the initial symptoms are subtle, proper diagnosis is often delayed. To diagnose posterior cortical atrophy, doctors begin with a physical examination, mental status exam, and a neurological exam. Patients may also have an ophthalmic exam, blood tests, and MRI, PET, or SPECT scans. Although posterior cortical atrophy cannot be cured, treatments are available to slow the progression of the disease and improve quality of life. Medications, physical and occupational therapy, support groups, and home modifications are all recommended to help patients with this condition.
