Sunrise Session
Your Brain on Drugs: Alcohol
Your Brain on Drugs: Alcohol
Sunrise Session

ORGANIZERS: Andre Obenaus, Pia Maly Sundgren

 
Monday, 18 June 2018
S05  07:00 - 07:50 Moderators:  Andre Obenaus, Natalie Zahr

Session Number: S-M-07

Overview
The sunrise sessions will provide an overview of the effects of common legalized drugs (alcohol, nicotine, cannabis) and their effects on the developing and adult brain.

Target Audience
Basic scientists to clinicians will benefit from this overview of the effects of alcohol, nicotine, and cannabis using neuroimaging as a biomarker.

Educational Objectives
As a result of attending this course, participants should be able to:
-Name the current knowledge of the effects of drug exposure to brain;
-Identify the neuroimaging methods/techniques to investigate drug exposure; and
-Describe the changes to the developing brain as a result of drug use

Alcohol: WM & Alcohol
Natalie Zahr, Edith Sullivan, Adolf Pfefferbaum
Brain imaging technology has allowed researchers to conduct rigorous studies of the dynamic course of alcoholism through periods of drinking, sobriety, and relapse and to gain insights into the effects of chronic alcoholism on the human brain. Magnetic resonance imaging (MRI) studies have distinguished alcohol-related brain effects that are permanent from those that are reversible with abstinence. In support of postmortem neuropathological studies showing degeneration of white matter, MRI studies have shown a specific vulnerability of white matter to chronic alcohol exposure. Such studies have demonstrated white-matter volume deficits as well as damage to selective gray-matter structures. Diffusion tensor imaging (DTI), by permitting microstructural characterization of white matter, has extended MRI findings in alcoholics. This lecture will focus on DTI findings in neurological disorders that commonly co-occur with alcoholism, including Wernicke's encephalopathy, Korsakoff's syndrome, and hepatic encephalopathy. Also reviewed are neuroimaging findings in animal models of alcoholism and related neurological disorders. The dynamic course of alcoholism presents a unique opportunity to examine brain structural and functional repair and recovery.
