Compaired to neurologically normal controls, the number of large neurons was reduced by approximately 65% in the caudate nucleus and putamen in these diseases and especially, in AD and GuamPDC, by more than 90% in the nucleus accumbens. The decreased number of large neurons in the neostriatum was significantly correlated to that in the bnM in AD and GuarnPDC, but not in PSP. The remaining large neurons in the neostriatum and nucleus accumbens of these three diseases contained neurofibrillary tangles (NFTs). The NFTs were composed varying amounts of 21-to 25-nm wide paired helical filaments admixed with straight tubules (STs) in AD and GuamPDC, and composed mainly of STs in PSP. Extremely severe loss of large neurons in the nucleus accumbens in AD and GuamPDC may be linked to marked degeneration of the limbic and ventral tegmental areas and nucleus dorsal raphe.}, pages = {475--480}, title = {加齢および痴呆と基底核}, volume = {108}, year = {1994} }
