The rubbing of the hands is one of the clinical manifestations of Parkinson’s syndrome. It is a degenerative disease of the substantia nigra and substantia nigra striata pathways that occurs in adults over middle age. 10% of patients have a family history; some patients can have similar manifestations due to encephalitis, cerebral atherosclerosis, and traumatic brain injury. The cause of Parkinson’s disease is not well understood. It is now recognized that the cause of Parkinson’s disease is degenerative changes of nerve cells, with the main lesions in the substantia nigra and striatum. The gradual decrease in the number of nigrostriatal cells and the gradual loss of their function leads to a decrease in a substance called dopamine, which causes the above symptoms. According to the results of animal experiments and epidemiology, Parkinson’s disease also has a genetic relationship. According to the cause, tremor paralysis symptoms can be divided into two categories, one is called primary tremor paralysis, that is, no clear cause can be found or the cause may be related to genetics, we will call it Parkinson’s disease or Parkinson’s disease. The other category is called secondary tremor paralysis, that is, due to some kind of encephalitis, poisoning (such as carbon monoxide, manganese, cyanide, reserpine poisoning, phenothiazines and butylphtalazine and tricyclic antidepressants and other drugs poisoning, etc.), cerebrovascular disease, cranial injury, brain tumor, etc., we also call it Parkinson’s syndrome or Parkinson’s syndrome, tremor paralysis syndrome. 1, Parkinson’s disease is mostly seen in the elderly, while combined with plant nerve dysfunction, digestive function more than a decline in gastrointestinal peristalsis weakness, spasm, prone to constipation and excessive skin oil secretion, etc.. We should take into account the patient’s condition, dietary preferences, pay attention to the structure of food ratios, side dishes, meat and vegetables, and the combination of fancy varieties. Eat more fiber-rich and easily digestible food, eat more fresh vegetables, fruits, drink more water, eat more foods containing tyramine such as melon seeds, almonds, sesame, skim milk, etc. can promote the synthesis of dopamine in the brain, and properly control the intake of fat. 2. Protein diet should not be excessive, blindly giving too much protein diet can reduce the efficacy of levodopa, because the large amount of neutral amino acids produced in protein digestion can compete with levodopa to enter the brain and affect its efficacy. Therefore, the daily requirement of protein is 0.8-1.2g/kg body weight, and the supply of protein is ensured by giving eggs, milk, fish and meat in the diet. If there is fever, decubitus ulcer and other conditions, the supply of protein should be increased. 3.For people with mastication and swallowing dysfunction, it is appropriate to sit down when eating, and foods that are easy to chew, easy to swallow, high in nutrition and high in fiber should be chosen. Recall the swallowing steps before eating. Let them swallow the excess saliva in the mouth when eating, move the food around with the tongue when chewing, eat little at a time and eat slowly, drink water after eating and swallow the residual food to prevent aspiration pneumonia. 4. For patients with diabetes, a diabetic diet should be given; for patients with coronary heart disease and hypertension, a diet high in sugar and vitamins and moderate protein is appropriate, and the intake of animal fat and salt should be restricted.
