A morphologic study of central nervous system aging in Hiroshima, Japan. 1978

R L Wollmann, and Y Mitsuyama, and L S Webber

The presence of intraparenchymal small vessel arteriosclerosis, senile plaques, neurofibrillary tangles and granulovacuolar degeneration was quantified in the brains of autopsided patients from three age groups: 1) 90--99 years old 2) 70--79 years old and 3) 50--59 years old. Neurofibrillary tangles particularly in the hippocampus were the best indicator of chronologic aging, but senile plaques and granulovacuolar degeneration were also age related. Intraparenchymal small vessel sclerosis, cerebral infarction and hemorrhage, cause of death and radiation exposure at the time of the atomic bomb explosion in Hiroshima apparently had little or no effect on the development of these aging changes. Each type of aging change appeared to be independent of the others, to progress to a different combination of physiologic processes.

D001921 Brain The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM. Encephalon
D002537 Intracranial Arteriosclerosis Vascular diseases characterized by thickening and hardening of the walls of ARTERIES inside the SKULL. There are three subtypes: (1) atherosclerosis with fatty deposits in the ARTERIAL INTIMA; (2) Monckeberg's sclerosis with calcium deposits in the media and (3) arteriolosclerosis involving the small caliber arteries. Clinical signs include HEADACHE; CONFUSION; transient blindness (AMAUROSIS FUGAX); speech impairment; and HEMIPARESIS.
