Brain scans find why some people 'black out' after drinking
People who wake up after an evening's drinking and find the details are a little fuzzy might be reassured by a new study.
People who suffer memory loss don't always do so because they drink more than others certain brains are just prone to losing memories when under the influence, according to a new study using MRI brain scanners.
The Hangover: Researchers found that alcoholic blackouts aren't necessarily due to drinking more than others some people have a chemical 'switch' that makes them forget
'Our study's findings suggest that some people are more likely to experience alcohol induced blackouts than others due to the way alcohol affects brain activity in areas involved in self monitoring, attention, and working memory,' said Reagan R. Wetherill of the University of California, San Diego.
Wetherill says, 'Some people may be more vulnerable to alcohol's effects than others. In other words, just because your friend may be able to drink a certain number of drinks and appear to be functioning fine, it does not mean that you or everyone else can.'
'Blackouts',replica alhambra clover necklace, where very heavy drinkers wake up and are unable to remember anything that happened, are quite rare, says Weatherill but their cousin,replica van cleef and arpels magic alhambra necklace, the 'brown out', where details vanish, is much more common.
The study using 24 students, 12 of whom suffered 'brown outs' while drinking, and 12 who did not, challenged the students to complete memory exercises both while drunk and while sober.
The study found that the students had similar abilities to remember and to multi task while sober but alcohol acted as a 'magic switch' for some which stopped them remembering.
It suggests there is a biochemical trigger for some people to forget what happens while drinking.
'Through use of imaging technology, this study has made the really intriguing finding that the unique patterns of blood flow and neural activity seen in persons prone to experience those amnestic phenomena emerged only after they became intoxicated,'she said.
'That finding,replica vca sweet alhambra necklace, taken together with results from prior research on fragmentary blackouts, suggests there are individual differences in how alcohol impacts memory.'
'Alcohol intoxication reduced activity in a brain region involved in 'multitasking,replica van cleef black onyx necklace,'' said Wetherill.
'Thus, alcohol appears to affect a person's ability to multitask, and also affects some people's ability to engage brain areas required for encoding and remembering previous experiences.'
'Irrespective of the specific type of alcohol related memory loss involved, if one is experiencing blackouts it is an important signal that negative personal and health consequences are more likely to occur,' said Weatherill.
'Not fully recalling one's life experiences, particularly those that occur while one is intoxicated, creates a state of vulnerability where the chances increase for the individual to incur all kinds of problems.'
