If you're over 60, drink up: Alcohol associated with better memory

To quote Lewis Carroll, "damn, that's good news." Actually, I think he said something like, "Frabjous day, etc., etc," but I think it what I wrote is closer to the point.
 This means the older author can continue to follow Ernest Hemingway's advise, "Write drunk, edit sober."  Well, no, not a good idea.  I mean editing sober is always a good idea, but writing drunk?  Not so much. But a glass of wine or a highball before?  Perhaps.

 Here's the story:

For people 60 and older who do not have dementia, light alcohol consumption during late life is associated with higher episodic memory -- the ability to recall memories of events.

Researchers from the University of Texas Medical Branch at Galveston, University of Kentucky, and University of Maryland found that for people 60 and older who do not have dementia, light alcohol consumption during late life is associated with higher episodic memory -- the ability to recall memories of events.

Moderate alcohol consumption was also linked with a larger volume in the hippocampus, a brain region critical for episodic memory. The relationship between light alcohol consumption and episodic memory goes away if hippocampal volume is factored in, providing new evidence that hippocampal functioning is the critical factor in these improvements.

This study used data from more than 660 patients in the Framingham Heart Study Offspring Cohort. These patients completed surveys on their alcohol consumption and demographics, a battery of neuropsychological assessments, the presence or absence of the genetic Alzheimer's disease risk factor APOE e4 and MRIs of their brains. The researchers found that light and moderate alcohol consumption in older people is associated with higher episodic memory and is linked with larger hippocampal brain volume. Amount of alcohol consumption had no impact on executive function or overall mental ability.

The Classic Guide
by William Zinsser
Findings from animal studies suggest that moderate alcohol consumption may contribute to preserved hippocampal volume by promoting generation of new nerve cells in the hippocampus. In addition, exposing the brain to moderate amounts of alcohol may increase the release of brain chemicals involved with cognitive, or information processing, functions.

"There were no significant differences in cognitive functioning and regional brain volumes during late life according to reported midlife alcohol consumption status," said lead author Brian Downer. "This may be due to the fact that adults who are able to continue consuming alcohol into old age are healthier, and therefore have higher cognition and larger regional brain volumes, than people who had to decrease their alcohol consumption due to unfavorable health outcomes."

Although the potential benefits of light to moderate alcohol consumption to cognitive learning and memory later in life have been consistently reported, extended periods of abusing alcohol, often defined as having five or more alcoholic beverages during a single drinking occasion is known to be harmful to the brain.

Workout supplements: An emerging eating disorder in men?

Image
therewontbeanydoves.wordpress.com When developing a fictional character, you may not think about the character using large amounts of over-the-counter dietary supplements.  Especially a man who uses large amounts of workout supplements. While there has been widespread publicity on the dangers of the non-prescribed use of anabolic steroids, not much is said about legal, over-the-counter supplements.  Are there risks?  And if so, what are they?  There are several things the writer should consider. Supplement use is becoming an eating disorder with many men who use them to prepare for and recover from a workout. There is growing evidence of a link between muscle-building supplements and testicular cancer. There is evidence that over-the counter medications and supplements are the most common causes of drug-induced liver failure (a rare event, but still a risk.)  There is even evidence that, “certain popular herbal and dietary supplements can also ...

Remember faces but not names? You got it wrong.

Source:   Daily Excelsior So, you think you're good at remembering faces, but terrible with names? New research has revealed we are actually better at remembering names than faces The cringe-worthy experience of not being able to remember an acquaintance's name leads many of us to believe we are terrible with names. However, new research has revealed this intuition is misleading; we are actually better at remembering names than faces. With the Christmas party season fast approaching, there will be plenty of opportunity to re-live the familiar, and excruciatingly-awkward, social situation of not being able to remember an acquaintance's name. This cringe-worthy experience leads many of us to believe we are terrible at remembering names. However, new research has revealed this intuition is misleading; we are actually better at remembering names than faces. The authors of the study, from the University of York, suggest that when we castigate ourselves f...

Children's drawings during abuse investigations

Image
Source:  rutherfordcountytn.gov I llustrations by children can be a critical tool in forensic investigations of child abuse. A recent study compared the results when child abuse victims were offered the opportunity to draw during questioning with results when victims were not offered this opportunity. "The act of drawing was not only an empowering experience for these children," said Dr. Katz. "We also found it to be forensically more effective in eliciting richer testimonies in child abuse cases. We had no idea the gap would be so great between those who drew and those who weren't given this option." A chance to express themselves Some 125 alleged child victims of sexual abuse were randomly selected for the field study. The children, aged 5-14, were questioned by nine well-trained forensic interviewers about a single occurrence of alleged sexual abuse. The children were divided into two sets -- a control group, questioned and allowed to rest during t...

M.I.T. Research Explains How Will Rogers Observation Works

Image
Finally it appears that MIT has gotten involved in proving Will's syllogism, "There are three kinds of men. The one that learns by reading. The few who learn by observation. The rest of them have to pee on the electric fence for themselves." Read his statement carefully.   ONE learns by reading.   A FEW who learn by observation. Then there's the rest of us. The reason for this, it turns out, is a special circuit in the brain that you or I need to have a functioning version of to actually learn by observing others.  Based on how we all behave, it is a circuit most of us must be missing.   Or perhaps it shorted out the first time we peed on an electric fence and it has yet to grow back.   *  *  *  *  * Brain circuit helps us learn by watching others Scientists pinpoint neural interactions that are necessary for observational learning Researchers have identified a brain circuit requir...
