  • Title: Morphological changes in the corpus callosum in chronic alcoholism.
    Author: Tarnowska-Dziduszko E, Bertrand E, Szpak GM.
    Journal: Folia Neuropathol; 1995; 33(1):25-9. PubMed ID: 8673416.
    Abstract:
    In a group of 66 patients (age 24 to 78 years) with the clinical diagnosis of chronic alcoholism the changes in the corpus callosum were evaluated. The period of alcohol abuse varied from 3 to over 30 years. In 57 cases atrophy of the corpus callosum was noted. The trunk was involved most frequently. Myelin sheaths exhibited abnormalities from slight pallor to total destruction. In 19 cases the damage of myelin sheaths was restricted to disseminated, perivascular, spongy degenerations. The vessels were sclerotic, especially periventricular ones exhibited degenerative changes. Perivascular gliosis was also seen. Conclusions from the present study indicate that the structural changes observed in the corpus callosum during chronic alcohol abuse are connected with CNS involution and with degenerative changes within vessels walls. The damage of myelin sheaths localized in our material similarly as Marchiafava-Bignami disease, differs from the later by less advanced changes, perivascular spreading of demyelination, and frequent destruction of axons.
