- Reduced hippocampal volume among adolescents with alcohol use disorders without psychiatric comorbidityBonnie J Nagel
Department of Psychiatry, University of California, San Diego, School of Medicine, 9500 Gilman Drive, La Jolla, CA 92093-0804, USA
Psychiatry Res 139:181-90. 2005..Because hippocampal volume did not relate to alcohol use characteristics, it is possible that premorbid volumetric differences could account for some of the observed group differences in hippocampal volume...
- Hippocampal volumes in adolescents with and without a family history of alcoholismKaren L Hanson
VA San Diego Healthcare System, Psychology Service, San Diego, California, USA
Am J Drug Alcohol Abuse 36:161-7. 2010..However, differences in hippocampal volume may be due to risk factors such as a family history (FH) of alcoholism. We examined hippocampal volumes in youth with and without a FH of alcoholism prior to the initiation of alcohol use...

Department of Psychiatry, Yale University, New Haven, CT, USA
Alcohol 44:111-7. 2010..Longitudinal studies will be needed to ascertain the degree to which emergence of binge drinking is linked temporally to these brain response patterns...
