Are mental illness and mental illness the same thing?

What is the difference between neuropathy, neurosis and psychosis?

In daily life, people often use the word "mental illness" when joking or swearing. In fact, what people want to express in their hearts is mainly the meaning of "mental illness". Ordinary people don't know what the relationship between neuropathy, neurosis and psychosis is, and sometimes even think that they are the same thing. In fact, the three concepts are very different.

(1) neuropathy. Neuropathy refers to an organic disease that occurs in the nervous system. According to the different positions and functions of nerves, the nervous system can be divided into central nervous system and peripheral nervous system. According to the different objects of nerve control, the nervous system can be divided into somatic nerve and visceral nerve. Neuropathy refers to the anatomical and pathological features of central and peripheral nerves or visceral nerves and somatic nerves, and its main feature is the organic pathological changes of nerves.

(2) neurosis. Neurosis, also known as neurosis, psychosis or neurosis, is a group of mild psychological disorders. Neurosis is caused by psychological factors, mainly subjective feelings, without corresponding organic damage. The performance is that the general social adaptability of the parties remains normal or has little influence; Have good self-knowledge, fully feel their discomfort, and generally take the initiative to seek treatment.

(3) mental illness. Mental illness refers to a serious psychological disorder, and patients' cognitive, emotional, will, action, behavior and other psychological activities may appear persistent and obvious abnormalities; Unable to study, work and live normally; Action behavior is difficult to be understood by ordinary people, and it looks strange and different; Under the control of morbid psychology, the act of committing suicide or attacking or hurting others; There are different degrees of self-knowledge defects, and patients often lose judgment on their mental symptoms, think that their psychology and behavior are normal, and refuse treatment.

In many people's minds, there is often a wrong concept, which is to confuse mental illness with mental illness. Whenever I hear someone say "psycho", I immediately think of "madman" and "fool". Therefore, many literary publications, televisions and movies often mistake mental illness for neuropathy. In fact, mental illness and neuropathy are two completely different diseases and cannot be confused.

Mental illness, also known as mental disorder, is the result of abnormal brain function. The existing instruments and equipment can't detect the destructive changes of brain structure. According to the available data, mental illness is caused by the disorder of biochemical processes in patients' brains. Some patients have more central nervous mediators, some patients lack some central nervous mediators, or some metabolites in the body accumulate too much in the brain. Because of the abnormal brain function of mental patients, these patients have obvious mental activity abnormalities, such as talking to themselves inexplicably, crying and laughing, sometimes yelling at the air, sometimes disheveled, and even naked in front of the public. ...

Neuropathy is the abbreviation of nervous system disease. As mentioned above, the nervous system is an important system in the human body, which coordinates the functions of various organs in the human body to adapt to the changes of the external environment and plays the role of "headquarters". Anything that can damage and destroy the nervous system will cause nervous system diseases. For example, head trauma can cause concussion or brain contusion; Bacterial, fungal and viral infections can lead to various types of encephalitis or meningitis; Congenital or hereditary diseases can lead to brain retardation in children; Hypertensive cerebral arteriosclerosis can cause cerebral hemorrhage and so on.

So, what are the symptoms of common nervous system diseases? Headache, dizziness, abnormal sleep, tremor, unsteady walking, rubber paralysis, hemiplegia, numbness of limbs, convulsions, coma, uncontrollable urination and muscle atrophy are the most common manifestations. Generally speaking, symptoms can be divided into two categories: one is irritating symptoms, manifested as pain and numbness; The other is a destructive symptom, which is characterized by paralysis. Of course, some mental patients can also show a certain degree of mental disorder, but this kind of mental disorder is different from mental patients, and doctors can distinguish it according to symptoms, examinations and various tests.

It can be seen that neuropathy and psychosis are two different diseases, and their causes and clinical manifestations are also different, so we should make these two concepts clear in our daily life. Patients with mental illness should be advised to go to a mental hospital or psychiatric department for medical treatment; Neuropathy patients should go to the neurology department to see a doctor.

It should be noted that neurasthenia is completely different from neuropathy and psychosis and cannot be confused.
