Research Abstract

Cognitive dysfunction and brain atrophy observed in alcoholics could improve partially by abstinence. Brain-derived neurotrophic factor (BDNF), a factor adjusting the neuronal growth, synaptic functions, and survival and growth of neurons in the brain, shows neuroprotective effects. Polymorphism of the BDNF gene has been associated with risk of neuropsychiatric disorders such as schizophrenia and mood disorders, although relationship between BDNF gene polymorphism and recovery from alcohol intoxication is unclear. In this study, we examined this issue. As a result, we found no significant effect of BDNF gene polymorphism in the control as well as patients groups in any of neuroimaging findings, suggesting that further evaluations with more participants will be required.
