Scary analyzes reveal that the damage to the brain by alcohol lasts up to SIX WEEKS after stopping drinking.
- Experts in Germany and Spain examine the brains of alcoholics and non-drinkers
- They found that there was less activity in the brain of the drinkers even weeks later.
- Areas of the brain controlling emotions, behavior and memory have been affected
Headaches, nausea and fatigue caused by hangovers usually disappear the next day.
But one study found that your brain could still feel the effects of alcohol for six weeks.
Scientists have used brain scans of alcoholics to find white matter – parts of the brain containing nerves – continues to change after more than a month of sobriety.
Analyzes by Spanish and German researchers revealed that there was significantly less electrical activity (indicated by the blue lines) in the brain of an alcoholic after two weeks of sobriety (left). ) that in the brain of a teetotaler (right).
Researchers from the Spanish Institute of Neuroscience and the Central Institute of Mental Health in Germany have examined the brains of 90 alcoholic men.
The patients had been hospitalized because of their alcohol problems and the scanners were compared to 36 men who were not addicted.
And although it is known that alcohol consumption changes the way nerves communicate in the brain, experts have realized that changes continue when smoking stops.
Although drinking can make people happier and more sociable, excessive drinking can damage parts of the brain that control thoughts and movements.
The analyzes showed that there was significantly less electrical activity in the brain of the drinkers than in those of the phone calls, even after two weeks of sobriety.
The changes were still present in the brain after six weeks of absence of alcohol, according to research published in the journal JAMA Psychiatry.
The researchers said their findings run counter to the conventional wisdom that alcohol damage ceases when consumption is over.
Dr. Santiago Canals, one of the authors of the study, said: "Until now, no one could believe that without alcohol, brain damage would progress."
The analyzes showed that the two most affected areas were the hippocampus and the prefrontal cortex.
Memories, emotions, decision-making and behavior are controlled by these parts of the organ, suggesting that these features could be particularly impaired.
"We found that at two and six weeks of abstinence, microstructural changes had progressed," the scientists wrote in their report.
They said the journey of nerve signals continued to be limited in the brain.
And they added, "These results challenge the conventional wisdom that microstructure changes begin to return to normal. [normal] immediately after you stop using alcohol. & # 39;
