In our life, we often encounter such elderly people who behave differently from normal people, who have tremors in their hands, feet and even head at rest, slow movement, muscle tonus and postural gait instability when moving, and these people are manifesting a common medical disease – Parkinson’s disease, which is of course translated from foreign names, in layman’s terms, also known as senile tremor paralysis. People are curious to ask what causes it. As medicine has evolved, it is true that the causes of many diseases have been clarified, but there are also many diseases whose causes are unclear, or where the cause of a certain part or stage is clear, but the underlying cause is not yet clear. The human brain is probably the most complex, vivid and interesting structure in the world, it is a huge “engine room”, where each part manages a certain function of the person. “In addition, there is a structure called “striatum” in the deep part of the brain. Medical scientists believe that these brain structures are capable of producing specific substances that flow through these structures. One of these substances is called “dopamine”, which affects the normal activities of people, and if it is not produced in sufficient amounts, it can cause tremors and movement disorders. This is the common medical understanding of what happens in Parkinson’s disease. Again, one may ask, under what conditions is this dopamine produced in insufficient amounts? Obviously, using the theory of production, either the “machine” is faulty or the “raw material” is inadequate, which is why the disease is more common in people of older ages. People also ask why some people of the same age are sick and others are normal? This is similar to the causes of other diseases in medicine, and is the result of multiple factors and individual differences. At present, it is believed that the structural degeneration of these brain tissues with age is the main one, which means that their ability to produce dopamine decreases, which is the main one, but family genetic factors, the influence of individual living environment, and different living habits also have different degrees of influence with the disease, which is the reason why some people of the same age have it and some do not. A clear understanding of the causes of the disease can understand the principle of treatment, according to the reasons described above, two types of treatment is desirable, one is drug therapy, for the human brain can not produce enough dopamine, we can give him ready-made dopamine, now the internal medicine doctors are doing this, known as dopamine replacement or complementary therapy. Another approach is to target structures to figure out what to do, and that’s what functional neurosurgeons are currently studying and doing, destroying those related structures that inhibit or bind the dopamine-producing structures, or inhibiting its action through stimulators. These methods make up for the lack of drugs that also don’t work. Since it is a degenerative disease of the elderly, the goal of treatment is certainly not to cure the disease, but to control the symptoms and improve the quality of life so that these elderly people live as long as they should as other elderly people. To achieve one of the above goals, early diagnosis must be made, early drug intervention, and after standardized drug treatment, still cannot improve, surgical treatment is given as early as possible, and the current deep electrode implantation stimulation technique is a more ideal choice, although it is a surgical procedure, the damage is small and the elderly can afford it, but the cost is relatively high, and the elderly generally depend on their children financially, so the patients themselves are not determined enough and need family members Therefore, the patient himself is not determined enough and needs encouragement and support from his family. The good thing is that the domestic machine has been used in the clinic, the cost has been reduced by half, and the medical insurance also allows the reimbursement, and the personalization can be done with 50-60 thousand Yuan. The happiness of the elderly requires the attention of the society, the state and the care of the family.
