Le·wy bod·ies

(lā'vē),
intracytoplasmic neuronal inclusion; bodies especially noted in pigmented brainstem neurons and seen in Parkinson disease, diffuse Lewy body disease, occasionally in Alzheimer disease, and rarely in healthy old people.

Lewy bodies

[lā′wē, lo̅o̅′ē]
Etymology: Frederick H. Lewy, German neurologist, 1885-1950
concentric spheres found inside vacuoles in midbrain and brainstem neurons of patients with idiopathic parkinsonism, Alzheimer's disease, and other neurodegenerative conditions.

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).

Specifically, the guidelines, which were last issued in 2007(2), note that SPECT "may increase diagnostic confidence in the evaluation of dementia," adding that dopaminergic SPECT imaging with DaTSCAN is useful in differentiating AD from dementia with Lewy bodies (DLB)(1), a neurological condition that is similar to AD in that it results from the death of nerve cells in the brain.
