In everyday life you often encounter things that don’t go your way. When you do something wrong or say something wrong, someone says you are a psychopath. It is easy for people to say psychosis as neurosis, but in fact, neurosis and psychosis are not the same disease, they are two different diseases, and they have essential differences. Neuropathy refers to organic lesions collected from central nervous system or peripheral nerve diseases, such as: cerebrovascular disease, infection, poisoning, trauma, degeneration, compression, or Camp B. It may manifest as limb paralysis, aphasia, sensory impairment, muscle atrophy, and involuntary movements. Psychosis is a disorder of brain activity due to the influence of internal and external harmful factors (social environment, family, physical, mental, genetic, etc.). The main manifestations are disorders in sensory awareness, perception, thinking, emotion, will and behavior, hallucinations and delusions, lack of initiative to seek medical help, lack of self-awareness, and reduced ability to take care of oneself, which can seriously affect social security and the safety of family members and oneself.
