The memory is unique and has not yet been fully explored, so in the future we will have to make many discoveries. Often she plays by her own rules! Scientists claim that the main cause
of a memory failure is malnutrition. Not systematic meals, malnutrition and overeating - all this leaves its mark on the state of the human body. Lack of dairy products, fish and meat in the diet, undoubtedly, leads to a deficiency of vitamin, which is responsible for brain activity (B12). Take note that if you are losing weight, in no case do not deprive yourself of this vitamin.
Another enemy of our body, provoking a memory failure, is our excess weight. The presence of cholesterol in the blood leads to a narrowing of blood vessels, blood flow is reduced, respectively, the brain does not work at full strength - it is less saturated with oxygen, and high pressure leads to physical inactivity. Usually these two factors are inextricable from each other.
Another enemy of memory is alcohol. Bitter venom has a negative effect on the brain, as evidenced by such consequences as: blurry vision, slow reaction, stumbling legs, confused speech and memory failure. All these "special effects" happen after taking alcoholic beverages. It only saves that all these symptoms that appear after taking only a small amount of a dose of alcoholic drinks quickly disappear after the cessation of alcohol intake. However, if you drink alcohol very often or in huge doses, then their negative effect on brain cells is noticeable even after the direct effect of alcohol has long been over.
Personally, I am more inclined toward a psychological explanation of the concept of "memory failure." And I want to defend our memorable mechanism. I’ll clarify right away that this will not be about senile changes in memory, but about elementary rejection of information.

Note that memory is trying to protect its owner from unnecessary stress and psychological trauma, and does it very skillfully. Let's say the girl quarreled and subsequently broke up with her boyfriend. She is ready to accuse him of all sins, in every way assuring herself that he is bad and does not suit her at all. However, after a certain time, her brain gives out only the best, brightest and happiest moments. These are tricks of memory - she made sure that we get only good emotions.
People who have an accident often do not remember the details of the terrible tragedy. The more stress for the body, the better the memory hides what we do not need to remember. You see, a memory failure is sometimes even useful: there are things that we better forget about. Never complain about your memory, it helps us all the time, you only need to support it, train and supply vitamins.
Before worrying about memory lapses, think about why your body started this game with you. Imagine what a difficult task our brain performs. Short-term memory, permanent memory ... Everything is laid out on the shelves. And we can always extract the necessary information from its bowels. Do you think memory lapses are a disease? Think about whether this is actually so. Or is it a natural process based on moral and physiological laws. Well, if memory lapses, the symptoms of which are inattention and forgetfulness, become more frequent and causeless, consult a doctor.
