RECOVERY OF HIPPOCAMPUS-RELATED FUNCTIONS IN CHRONIC ALCOHOLICS DURING MONITORED LONG-TERM ABSTINENCE

Alcohol and Alcoholism 2007 42(2):92-102;


The hippocampus (HC) is characterized by high vulnerability to noxious influence, but also by a considerable regenerative potential. Although deficits in HC-related functions are among the most commonly reported cognitive sequelae in alcoholism, little and conflicting information is available concerning regeneration upon abstinence.

The present study has been designed to evaluate (i) the frequency of measurable dysfunction in so called HC tests and (ii) its predictive value for risk to relapse in a cohort of 50 severely affected chronic alcoholic patients and (iii) to monitor recovery of HC-related functions upon strict abstention from alcohol.

Demonstrating slow but remarkable regeneration of HC functions upon strict abstention from alcohol, our data strongly support abstinence-oriented long-term treatment of alcoholics. The absence of functional recovery in patients with additional causes of brain damage might be explained by the ‘dual hit’ exhausting the regenerative potential of the HC.
