The Mangan classification of degenerative disorders categorizes these disorders into three main groups: cortical, subcortical, and mixed. Cortical degenerative disorders primarily affect the cerebral cortex, leading to impairments in cognitive and motor functions. Subcortical degenerative disorders primarily affect the structures beneath the cortex, leading to disturbances in movement, coordination, and emotion. Mixed degenerative disorders involve a combination of cortical and subcortical pathology, resulting in a wide range of symptoms affecting both cognitive and motor functions. This classification helps to organize and understand the diverse array of degenerative disorders based on their underlying neuroanatomical and clinical features. **
