No changes in neocortical cell volumes or glial cell numbers in chronic alcoholic subjects compared to control subjects
Alcohol and Alcoholism 2007 42(5):400-406

To study if the total glial cell population in the neocortex is intact in subjects with a history of severe alcohol abuse compared to control subjects. Further, to investigate whether the cortical nerve cell nuclei and nerve cell perikarya volumes are the same in chronic alcoholic subjects as in the control subjects.

We found the mean neuronal cell volumes to be unaffected by severe alcohol abuse (p = 0.84) and a normal total number of glial cells (p = 0.39) in chronic alcoholic subjects compared to control subjects.

Only glial cells and dendritic/synaptic changes have so far been reported in stereological studies of the brains of alcoholic subjects. We thus have increasing evidence that it may be possible for some individuals to return to their previous cognitive abilities after cessation of alcohol which may give hope and encouragement for chronic alcoholic subjects to stop the abuse.
