Anxiety scans show how brain damage from alcohol lasts up to six weeks after you stop drinking
- Experts in Germany and Spain scanned the brain of alcoholics and non-addicts
- brain of those who are Even a few weeks later
- The brain areas that control emotions, behavior and memory are influenced
Headaches, illness and fatigue caused by a hangover usually go the next day.
But your brain can still feel the consequences
Scientists have used a brain scan of alcoholics to find white matter – parts of the brain that contain nerves – continue to change after more than a month of sobriety
researchers in Spain and Germ, any detected there is significantly less electrical activity (indicated by blue lines) in the alcoholic brain after two weeks of sobriety (left), than in the brain of the tobacco (right)
Researchers from the Spanish Institute for Neurology and the Central Institute of Mental Health in Germany have examined the brain of 90 male alcoholics.
Patients were hospitalized due to drinking problems, and scans were compared with 36 men who had no addiction.
And although it was known that the use of alcohol changes the way nerve communication in the brain, experts realized that changes would continue when the drink stops.
Scans have shown that the electrical activity of those in the brain in the brain is much less than in three-stroke – even after two weeks of sobriety.
A patient is present in the brain after six weeks of lack of alcohol, according to a study published in the journal JAMA Psychiatry.
The researchers said their findings contradict the generally accepted notion that alcohol damage stops when alcohol ends.
The two worst sites, the scans shown, were hippocampus and prefrontal cortex.
Memories, emotions, decision-making, and behavior are controlled by those parts of the Authority, which suggests that these characteristics may be particularly modified.
"We found that after two and six weeks of retention, the microstructural changes progressed," the researchers wrote in their report.
They said that the movement of the nerve signals continued to be restricted to the brain
And they added: "These results deny the generally accepted idea that microstructural changes begin to return to [normal] immediately after the termination of alcohol consumption."
Alcohol damages the brain more than cannabis, suggested research in February 2017.
Unlike alcohol, marijuana does not affect the size or integrity of white or gray matter in the brain, even after many years of exposure.
Gray matter allows the brain to function, while white controls the bond between nerve clusters.
Research author Professor Kent Hutchinson of the University of Colorado Boulder said: "Although marijuana may also have some adverse effects, it is definitely
Scientists add, however, that research on the mental effects of cannabis is still very limited.
Leading author Rachel Teyer said: "Especially when using marijuana, we still do not know how much it affects the brain.
In the United States, 44 percent of people aged 12 years and older use cannabis at some point in their lives.
Although their results turn out to be positive, do not The rs also add that there is a long way before cannabis is likely to be widely legalized.
Many are still concerned about how a class C drug affects people of all ages, manages pain and causes addiction.
