Classic Cases Mr. Li (a pseudonym) 29 years old, is an interior decorator, art professional background, income is good, the future looks good. Two years ago, a small gathering of friends, but let him regret it …… It was the year before last, the Spring Festival holiday day, a few friends meet to play in the bar, friends asked him to smoke some methamphetamine, said this thing can inspire the design inspiration. Out of friends “face”, sucked a little, that night at home to do the design really feel more active than before, energetic thinking. Afterwards, friends occasionally asked him to smoke a little, he did not much excuse, in the next 1 year or so, about 10 times. In April last year, after drinking methamphetamine, began to insomnia, the first more than ten days a day to night a little sleep can not sleep, can not sleep all night, more sleep during the day, and have a panic attack, it is difficult to concentrate. After nearly two weeks of sleepless days and nights, I had no choice but to take sleeping pills to maintain a short period of sleep. Since then, the more late at night, the more awake, always yawning during the day, drowsiness, slow reaction of thinking, memory loss, sometimes forgetting things, feeling numbness of the scalp, head swelling and pain, mental fatigue, unable to work. Everyday sad face, extremely poor mood, loss of appetite, grumpy. And always panic, tinnitus, timidity, nervousness, sometimes hands and legs shivering, feet unsteady standing before and after a slight rocking, walking is also unsteady left and right rocking. One day also had a hallucination, saw a friend holding a kitchen knife standing in the street to kill him, then extreme panic, fleeing the road. Afterwards, he was worried and scared for a long time, had episodes of rapid heartbeat, felt like he was going to collapse and go crazy, and was afraid to go out. When he had to go out, he was so scared in crowded places that he shivered and did not dare to look up at people. Have been to the city inside and outside of a number of hospitals, have done a number of tests, electroencephalography, electrocardiogram, liver and kidney function …… diagnosis are said to be phytoneurological dysfunction and sleep disorders or neurasthenia, prescribed a lot of drugs to eat eat a little effect has not been. By now it has been more than 8 months can not work and live a normal life. Yesterday, accompanied by his parents to the hospital drug dependence department. Expert analysis Mr. Lee’s condition is very typical, in the diagnosis of psychoactive substances caused by mental and behavioral disorders, in layman’s terms, is the methamphetamine poisoning caused by mental and psychological disorders. Why did Mr. Li suffer from insomnia, panic and hallucinations? The culprit is methamphetamine. Methamphetamine, a common illegal psychoactive substance, is chemically known as methamphetamine and belongs to the stimulant class of drugs. Methamphetamine is a stimulant drug. Methamphetamine strongly excites and damages the central nervous system, and is highly addictive; it is generally addictive when used several times, and sensitive people can become addicted to it once they use it. The first time a small amount of methamphetamine is used, the person often feels refreshed, energized, and even more focused. Repeatedly used several times or in slightly larger doses at one time, meth damages the central nervous system and some users soon develop psychosomatic and neurological symptoms. Meth’s damage to the central nervous system generally includes three aspects: (1) causing neurotransmitter disorders in the brain, causing an imbalance between the excitatory and inhibitory functions of the brain, for example, the anxiety, panic, panic and hallucinations exhibited by Mr. Lee are the result of over-excitatory brain function. (2) Directly lead to the apoptosis of nerve cells, commonly known as methamphetamine directly kills nerve cells, kills more nerve cells, will form brain atrophy, showing memory, intellectual decline, hallucinations, paranoia, personality changes, emotional control and behavioral disorders. (3) It leads to contraction and spasm of small blood vessels, especially cerebral blood vessels and cardiovascular vessels. Cerebral small blood vessel spasm, brain tissue will be insufficient blood supply, the formation of point or small pieces of necrosis, manifested by dizziness, headache, intelligence, memory loss, psychotic symptoms, emotional disorders. Spasm of small blood vessels in the heart, will myocardial ischemia, arrhythmia, manifested as panic, chest tightness, fatigue, etc.. A single super-heavy use of methamphetamine may also result in stroke or myocardial infarction. The series of mental, psychological and physical symptoms shown by Mr. Li in this case are precisely the result of damage to the central nervous system caused by repeated use of methamphetamine several times. Generally speaking, people have different physical qualities, different degrees of response to drugs, sensitive people use a few times or even once can appear chronic mental and psychological and neurological symptoms, and insensitive people tend to be addicted to the use of one to two years after the emergence of specific to different people need to be specifically analyzed. Treatment Countermeasures So how should such patients be treated? For the treatment of mental and behavioral disorders caused by psychoactive substances, the principles of balancing cause and effect, treating both the symptoms and the root cause, combining drug therapy with psychotherapy, and individualized treatment should be followed in treatment. First, methamphetamine is the root of the problem, patients should isolate and reject drugs, psychotherapy should be carried out throughout the whole process of treatment, through cognitive behavioral therapy, so that patients can understand the harm of drugs and learn how to reject drugs; at the same time, they should strengthen the determination and confidence in treatment and rehabilitation, and cooperate with the diagnosis and treatment process. Secondly, for drug-induced brain damage, treatment should be given to protect the brain, improve cerebral blood flow, repair the brain nerves, and rehabilitate brain function, including appropriate drug treatment and physical rehabilitation therapy, such as transcranial magnetic stimulation therapy. Thirdly, for mental, psychological and physical problems, medication should be given to treat the symptoms, so that patients can resume normal life and work as soon as possible. Although the apoptosis of brain cells can not be regenerated, but the brain tissue has a strong compensatory recovery ability, if we can do early treatment, with the diagnosis and treatment of the rehabilitation process, Mr. Li’s can still be restored to normal, without affecting the occupational function.
