| Alcohol doubles the risk of memory loss: |
Research in the United States has found that women and men who drink heavily in their 50s and 60s are at higher risk of memory loss in the next two decades.
The study, published in the American Journal of Geriatric Psychiatry, states that heavy drinking can impair mental processing in later life.
Researchers say this is a public health issue that needs to be addressed.
Scientists surveyed 6,500 middle-aged people about their past drinking habits.
Three Qs were asked:
1.people criticizes ,more drinker than normal?
2.Did he ever regret his drinking?
3.Did they ever take alcohol as the first thing to correct themselves or to get rid of addiction?
Anyone who answered yes to any of these three questions was considered to have a drinking problem.
Research has shown that such people are at high risk of memory loss in old age.
Dr Lane Long, lead researcher at the University of Exeter Medical School, told that: "We know that alcohol is generally harmful to the brain. It's not just about how much you drink or how much it affects you but about quantity and when your close start telling you are addicted to drinking ," he said. Utilize a certain amount of alcohol in a specific time , but if your answer of all the above 03 Qs is positive, then you have to drink less," he said.
Discover the secret to memory impairment:
According to American scientists, they have discovered the secret of memory impairment with age.
According to scientists, experiments on mice showed that a decrease in the amount of a specific protein in the brain can cause memory impairment.
It is hoped that this discovery will help to cure lost memory.
The research is printed in the journal Scien-Translational-Medicine (STM).
The study analyzed the brains of eight dead people between the ages of 22 and 88 who had bequeathed their organs for medical research after death.
The analysis showed that the gene that makes a particular type of protein weakens with age.
Later experiments on mice found that young mice with low levels of this protein did not perform well on memory tests, and older mice with artificially increased levels of this protein had better memory. Started working properly. According to Professor Eric Kendall, who was involved in the study, "The success of mice/rat in recovering from memory loss over time is very encouraging."
Why do we remember some things and forget some?

| Why do we remember some things and forget some? |
About eighty years ago today, the idea was put forward that man quickly forgets his negative or bitter memories. In 1930, psychologists collected life events from people and divided them into good and bad memories. Several weeks later, the experts suddenly spoke to them again and asked them to repeat their memories. Experience showed that people had forgotten 60% of their bad memories, while they had forgotten only 42% of the good memories.
We all seem to be familiar with these results because when we come back from the holidays we remember at first how bad our flight was but the things we liked during holidays we do not forget them.
After this initial psychological experiment, many more experiments were performed and experts began to accept the human habit of forgetting unpleasant events as a regular scientific theory. Therefore, in the 1970s, experts not only talked to people about their memories, but also asked the participants in the experiments to write down each event in a diary and write down how emotional they were about that memory.
But with 80 percent of the research being done in the United States at the time, it was unclear whether people in other countries and civilizations would soon forget their bad memories.
To address this apparent shortcoming in research, University of Ireland researcher Timothy Ritchie asked experts from 60 universities around the world to share their data and experiments so that they could see if the world Whether or not everyone remembers good things for a long time.
After this long experience, it became clear to Timothy and his colleagues that this was not limited to Americans, but that all people quickly forget their bad memories rather than good ones. In further experiments, experts found that people who do not have good memories actually suffer from severe depression.
