    Notes: Summary Neuronal loss from the frontal superior cortex of the brains of alcoholics has recently been documented. In addition to this, a reduction in the mean neuronal area was also seen in the frontal and motor cortices. This suggested a regional specificity of neuronal damage in the brains of alcoholics. Further quantitation of other cortical regions of the same cases as used in the above study has been performed. The frontal cingulate and temporal cortices were examined and there was found to be no significant alteration in the number of neurons when compared to a control population. There was, however, a significant reduction in the mean size of the neuronal soma in the frontal cingulate cortex (P 〈 0.05). These data support the hypothesis of regional variations in the severity of cerebral cortical damage in alcoholism with shrinkage of neurons in most regions examined but neuronal loss only in the superior frontal gyrus.

    Notes: Abstract Previous studies have identified alcohol, thiamine deficiency and liver disease as contributing to the neuropathology of alcohol-related brain damage. In order to examine the effects of alcohol toxicity and thiamine deficiency on serotonergic neurons in the median raphe nucleus (MnR), alcoholic and previously published Wernicke-Korsakoff syndrome (WKS) cases without liver disease, were compared with age-matched non-alcoholic controls. While there was no difference between the estimated number of serotonergic neurons in either controls or alcoholics without WKS (means of 63,010±8,900 and 59,560±8,010 respectively), a substantial loss of serotonergic neurons was previously found in WKS cases (mean of 19,050±13,140). Further analysis revealed a significant difference in the maximum daily alcohol consumption between these groups. However, analysis of covariance showed that the number or serotonergic neurons in the MnR did not correlate with the amount of alcohol consumed. Therefore, our results suggest that cell loss in the MnR can be attributed to thiamine deficiency rather than alcoholper se.
