Sogar leichte Alkoholtrinkern erhöht das Demenzrisiko, so die bisher größte genetische Studie. Die Studie zeigte einen stetigen Anstieg des Demenzrisikos mit zunehmender Alkoholkonsum, ohne dass ein Anzeichen von Nutzen in niedrigeren Niveaus war.

I’ve linked to the news release in the post above. In this comment, for those interested, here’s the link to the peer reviewed journal article:

From the linked article:

**Even light alcohol drinking raises dementia risk, according to largest genetic study to date**

A large-scale international study combining genetic data and observational records suggests that alcohol consumption of any amount may raise the risk of developing dementia. While earlier research indicated light drinking could be protective, this new study provides evidence that such findings may reflect reverse causation rather than a true beneficial effect. The authors conclude that reducing alcohol consumption could be an effective public health strategy to lower dementia rates.

These analyses told a different story. **They showed a steady increase in dementia risk as alcohol intake increased, without any sign of benefit at lower levels**. A genetically predicted increase in weekly alcohol consumption was linked to a 15 percent higher dementia risk. Likewise, genetic risk for alcohol use disorder was associated with a 16 percent increase in dementia risk.

The research team also analyzed how alcohol use changed over time in people who eventually developed dementia. Using repeated clinical alcohol screening data from the Million Veteran Program, they found that individuals who went on to develop dementia tended to reduce their alcohol intake in the years before diagnosis.

This suggests that lower drinking levels in people with early signs of cognitive decline may have contributed to the misleading appearance of a protective effect in past observational studies. In other words, rather than alcohol preventing dementia, it may be that the onset of dementia leads people to drink less.

The genetic analyses were bolstered by data from over 2.4 million individuals and considered a wide range of alcohol-related traits. This included both how much people drank and whether they exhibited problematic or dependent drinking patterns. Results were consistent across different types of alcohol exposure, and the findings held up in several sensitivity tests. Notably, the researchers found no evidence of a non-linear or U-shaped relationship in their genetic analyses. The more alcohol a person was genetically predisposed to consume, the higher their risk of dementia appeared to be.

> without any sign of benefit

What people perceive as benefit is highly subjective and likely differs from what medical researchers define as benefit.

For example, if it helps with socializing and prevents loneliness, there are enough studies to show that loneliness is also a health risk.

If this is from the Trump administration of pseudo science or based on one journal entry or study, then there is no possible validity and I will not come close to giving any amount of credence !

I drink all the time and my memory is fine also I drink all the time and my memory is fine 

But for years it’s been the alcohol fans ragging on pot smokers for being the ones who got dumber. Where the majority of studies show cannabis intake may have a “barely perceptible level of cognition impairment”, and this is after decades of chronic use. And alcohol used in that manner would not only dissolve a brain but most likely kill the user.
