| Abstract | Posterior cortical atrophy is a neurodegenerative syndrome characterized by a progressive decline in visuospatial processing and other posterior cognitive functions, relatively preserved memory and language in the early stages, and atrophy of posterior brain regions. Atypical Alzheimer's disease accounts for more than half of the cases, but dementia with Lewy bodies and corticobasal degeneration are also known. The symptoms are based on impairment of the bilateral dorsal/ventral visual pathways. Diagnosis may be delayed by ophthalmological consultation due to subjective visual complaints or overlooking abnormalities on routine cognitive screening. Early diagnosis can be achieved by detecting visuospatial cognitive impairment through appropriate examination and testing. With advances in neuroimaging and other diagnostic methods, it is becoming possible to diagnose underlying diseases. It is important to make an early diagnosis that leads to adequate treatment and management. |
