First, the cause of the disease, which is a gene-carrying recessive disorder. So there is a family tendency. I find in my clinic that 90% of the parents of children have low blood pressure, that is, one parent or the parent of the previous generation had blood pressure at 90/60 mmHg when they were young. As for the twitching symptoms adult parents do not always show them. It is possible that the disease was transient in childhood. Most of the symptoms do not show up in adulthood, or there are some compulsive movements that are not easily detected. The age of first onset of the disease is concentrated between 1-10 years. Predisposing factors: 1. Fever and recurrent respiratory infections. 2. 2, early and extensive learning of cultural knowledge, musical instruments, Go, abstract mental arithmetic. 3, Excessive and overly detailed attention, stereotyped rules, frequent reminders. 4, laboratory tests are generally not abnormal, and trace elements and allergens are not related. Treatment: 1. Exercise, blood pressure is impossible to change, but you can “move” the exercise to make the heart strong, to ensure good microcirculation, improve the state of oxygen supply to the brain, the brain will automatically adjust the “twitch” to regulate the rhythm of central media activity Promote self-healing. 2, exercise, more outdoor activities can broaden the horizons of relaxation, reduce the parents and children’s self-concern to achieve self-recovery. 3.Parents should be strong and restrain too much attention and reminders. 4. If the child is not a potential genius, it is better not to learn musical instruments, Go and mental arithmetic before the age of 7. Do not teach word recognition, poetry and arithmetic before the age of 5. 5, the conditions can be appropriate amount of Chinese medicine. Generally to strengthen the spleen and dissolve phlegm mainly accompanied by clearing heat and detoxification, small doses of short-term use of drugs to dispel wind. Do not use mineral heavy Chinese medicine. Children’s internal organs are delicate do not make a blow to cause unnecessary damage. Chinese medicine also does not have to be taken for a long time. 6, prohibit all kinds of psychotropic drugs. Rather not treat or use such drugs, the use of drugs is more harm than good. These drugs are: thiopride, haloperidol, Vistone, aripiprazole, clonidine, toltaren, kepulan. Without treatment, most children will also recover naturally to varying degrees. 7, do not have to spend a lot of money to treatment. Any treatment that is more than a thousand dollars a month is basically a scam. 8, the most important point is to stay away from the use of electronic products, such as not playing with cell phones and computers, including tablet computers, watch less television.
