Abuse of methamphetamine and methamphetamine can lead to mental abnormalities, which are not fully recognized by many patients’ families at the initial stage, or they may even think that these are just changes in the patient’s personality, or they may be half-hearted about what the patient says is “true” and mislead the patient. In fact, marijuana, methamphetamine caused by mental abnormalities in the clinical manifestations of which patients are almost the same, the following I will do a detailed answer to some of the representative symptoms one by one. Hallucinations Hallucinations are the most common symptom of patients, among which hallucinations are the most common. Patients may hear voices that do not exist, and often hear people talking in their ears, and the content of the speech is various, sometimes it is a lot of people talking badly about him, and sometimes it is a person who says everything he thinks. The patient cannot distinguish between what is a real voice and what is a hallucination, and is in a state of panic and confusion. The patient is very nervous because he thinks that what he is thinking is known and widely disseminated, so he thinks that everywhere is unsafe and there are monitors and bugs everywhere. Some patients may interact with the hallucinations, have conversations with them, or even argue with them, appearing to outsiders as talking to themselves. Some severe abusers may experience hallucinations, i.e., seeing something unreal, such as someone chasing them, and may appear to be emotionally tense, frightened, and impulsive. Some patients may experience hallucinations, such as smelling a meal with a bad odor or poison in the air. Delusions Delusions are distorted beliefs, pathological reasoning and judgments that do not conform to objective reality or to the level of education, but patients are convinced of them and cannot be persuaded, nor can they be persuaded by their personal experiences and experiences. 1. Jealous delusion: Jealous delusion refers to the patient’s unwarranted suspicion that his or her spouse is unfaithful to him or her and is having an affair. This symptom is difficult to identify clinically, and some of the patients’ family members are half-hearted about it. In fact, one key point to identify this symptom is whether the patient’s suspicion is generalized. Generalization means that the patient often suspects that his or her spouse is having an inappropriate relationship with one person at the beginning, and as the disease progresses, he or she gradually suspects that his or her spouse is having an affair with multiple people, even all members of the opposite sex, or even other members of the opposite sex in the family. If this generalization is present, it must be a psychiatric symptom. Some patients’ family members are often too shy to talk about this symptom, which may lead to misunderstanding of the patient’s condition. 2. Relationship delusion: Relationship delusion means that the patient thinks that things around him that are not related to him are related to him. For example, if the patient sees someone spitting on the roadside, he thinks that the person is spitting on him; if he sees others talking together, he thinks that they are talking about him together. Everything around him seems to be directed at him. 3. Delusions of victimization: Delusions of victimization are the most common in this kind of patients, which simply means that the patients suspect for no reason that they are being framed and hunted. Patients often believe that they are caught in a conspiracy, that they are being murdered by a group, and that they are being hunted down and killed. Patients may be nervous and fearful, hiding everywhere, or even calling the police for protection; some patients are on edge all day long, carrying sharp knives for self-defense, or in severe cases, “fighting back” with knives to hurt others. Some patients stay on high alert, stay awake all day, and even do not eat or drink because they suspect that the food is poisonous. Abnormal experience This kind of symptoms is also common among patients, mainly manifested as being stalked, being watched, and being bugged. Patients may think they are being followed by others, so they are nervous and fearful, and drive away or keep changing cars and rooms; some patients think there are monitors installed everywhere in the room, so they tear down the TV, refrigerator, and even the walls; many patients feel that there are eavesdropping devices installed in their cell phones or telephones, so they frequently change their cell phones or smash them, or even remove them to find a wiretap. The psychiatric classification of symptoms is relatively fixed, but the manifestation of these symptoms will be somewhat variable in different patients, and will not necessarily be as typical as I have described. Therefore, the patient’s family should try to understand as much as possible about the patient’s thoughts and send him/her to the doctor for a clear diagnosis in time to avoid delaying the condition. I hope the above will be helpful to you.
