There are many reasons for memory decline, among which, long-term lack of sleep, lack of exercise, lack of fresh air, excessive alcohol and tobacco, etc. Will lead to memory loss, which is a physiological reason. Long-term excessive anxiety, depression, excessive psychological pressure, etc. , will also make memory decline, which is a psychological reason. This kind of memory disorder is a functional disorder caused by brain fatigue, which has no damage to brain structure, so it is functional, temporary and reversible.

Excessive drinking can lead to memory loss and slow response.

Some diseases, such as neurasthenia, depression, cerebral arteriosclerosis and chronic sinusitis, are common causes of memory loss.

Patients with neurasthenia often show memory loss, and the fundamental reason lies in distraction and inability to concentrate, which affects memory ability.

Sleep is also closely related to memory, poor sleep will also affect memory function, and neurasthenia patients often have sleep disorders. From this point of view, patients with mental weakness have inattention and sleep disorders, leading to forgetfulness.

Smoking is harmful to people's brains. As smokers get older, their memory may decline. Studies have proved that smoking is one of the risk factors for dementia in the elderly. An important reason of dementia is that the blood flow in the brain is blocked, and smoking will just lead to blood vessel stenosis and insufficient blood supply to the brain.

When people with drinking habits have memory loss, this is a signal of chronic alcoholism.

If the memory ability of middle-aged and elderly people, especially those with hypertension and cerebral arteriosclerosis, fluctuates obviously, it may be the result of cerebral arteriosclerosis.

Therefore, paying attention to the law of life, combining work with rest, relaxing, staying away from alcohol and tobacco, strengthening physical exercise and actively preventing arteriosclerosis are important measures to protect brain health.

A small amount of alcohol has an exciting effect on the human body, which is generally not a big problem; However, when a large amount or excessive intake of alcohol, it will have an inhibitory effect on the nervous system of the human brain, that is to say, it will begin to be slow to respond, and the hearing, vision, language, hands and feet will be out of control, often accompanied by symptoms such as headache, dizziness, excitement, irritability, vomiting, etc., and in severe cases, it will appear unconsciousness, lethargy and acute gastroenteritis.

Because of the excitement of alcohol and the loss of self-control, ordinary drunkards behave arbitrarily and feel a bit like "little people become little people." They don't listen to other people's advice and do some abnormal things, such as talking crazy, fighting, fighting, throwing things and even losing the will to hurt and kill people. The effects of alcohol on drivers are: (1) blurred vision, disorientation or hallucinations, and inability to concentrate; (2) The tactile ability is reduced. Under the anesthesia of alcohol, it is difficult for hands and feet to control the steering wheel, joystick, throttle, brake and other operating systems, resulting in uncoordinated hands and feet. (3) the ability to judge is declining. Due to the slow response, it is difficult to accurately judge the road conditions (distance, speed, traffic lights), surrounding scenery and avoidance ability. (4) Fatigue, irregular driving, sometimes falling asleep on the steering wheel while driving.
