Lewy bodies

Abnormal intracellular proteins that occur in the nerve cells of the cerebral cortex, basal ganglia and pigmented brainstem neurons, causing Parkinsonism. If present in large quantities they as associated with dementia (diffuse Lewy body disease). (Frederic H. Lewy 1885–1950, US neurologist of German origin).

Although it is possible that both of the diseases may lie on a continuum of a single disease that begins with ADHD manifested in childhood and continues into adulthood as dementia with Lewy bodies "when neuronal loss and gliosis in the substantia nigra, locus coeruleus, and nucleus basalis of Meynert occur," the authors doubted that this hypothesis could be accurate because low dopamine levels in ADHD are not initially associated with Parkinsonlike or DLB symptoms.
