Cerebellum and cognition: Impact of co-use of alcohol and cigarettes

There is consistent evidence that having an alcohol use disorder is associated with abnormalities in the cerebellum, a structure attached to the bottom of the brain that is involved in coordinating posture and balance but also in supporting some cognitive functions. Cigarette smoking, which often co-occurs with alcohol use, has also been shown to impact brain structure and function, and co-use of these substances is purported to accelerate aging of the brain. A report published in the journal Alcoholism: Clinical & Experimental Research examines neuroimaging (MRI) data from 92 people in order to further investigate the impact of smoking and alcohol status on the volume of the cerebellum and related cognitive function.
