Alzheimer type II astrocyte

The Alzheimer type II astrocyte is thought to be a pathological type of cell in the brain; however, its exact pathology remains unknown. Like other astrocytes, it is a non-neuronal glial cell. It's mainly seen in diseases that cause increased levels of ammonia (hyperammonemia), such as chronic liver disease and Wilson's disease.[1]

They are not associated with Alzheimer's disease, but were first described by the same neuroscientist who first described the eponymous disease, Alois Alzheimer.[1]
