Consider Alzheimer disease, Lewy body disease, postencephalitic parkinsonism, idiopathic PD, ALS, and motor neuron disorders in the differential diagnosis of PDALS. Regarding treatment, patients do not respond to levodopa, and psychiatric treatment may be indicated. A progressive clinical picture is characteristic of both subtypes of PDALS. Death within 10 years is usual.
