Patients always forget things, mainly consider the following aspects of the cause: 1, related to psycho-psychological factors, patients who are under continuous stress or mental tension, will cause brain cells to produce fatigue, thus prone to the problem of forgetfulness. Excessive smoking and lack of vitamins may lead to memory loss; 2. Some psychological factors also have a non-negligible impact on the formation of amnesia in patients, such as emotional anxiety and depression in many patients, which can easily lead to low brain function activity; 3. Patients with brain atrophy or cerebral arteriosclerosis, insufficient blood supply to the brain, etc., can also easily lead to a decrease in brain function activity. Because the amount of blood to the brain is reduced, this can cause patients to have memory loss and usually have dizziness and dullness.
