First, anxiety.
Anxiety, also known as anxiety neurosis, is the most common neurosis, and its main feature is anxiety experience. It can be divided into chronic anxiety (generalized anxiety) and acute anxiety (panic attack).
The main manifestations are: anxiety without a clear objective object, fidgeting, autonomic nervous dysfunction symptoms, such as palpitation, shaking hands, sweating, frequent urination, exercise anxiety and so on. Pay attention to distinguish between normal anxiety. If the severity of anxiety is obviously inconsistent with objective facts or situations, or lasts too long, it may be pathological anxiety.
Second, depression.
Depression is the most common mental illness at present, characterized by persistent and long-term depression, and it is the main type of mental illness of modern people.
Clinically, we can see that we are depressed, unhappy, depressed for a long time in reality, from depression at the beginning to heartbreak at the end, feeling inferior, miserable, pessimistic and world-weary, feeling that we are desperately torturing ourselves every day, being negative and escaping, and finally even having suicidal tendencies and behaviors. The patient has somatization symptoms. Chest tightness and shortness of breath.
I just want to lie in bed every day and don't want to move anything. There is obvious anxiety. More serious people will have hallucinations, delusions, thinking (speech) disorders and other symptoms of schizophrenia.
Each episode of depression lasts at least 2 weeks, 1 year, or even several years, and most cases have a recurrence trend.
Third, neurasthenia.
Neurasthenia is one of the diagnoses of China's neurosis. It is precisely because of long-term tension and stress that mental excitement and mental fatigue occur, often accompanied by emotional distress, irritability, sleep disorders, muscle tension and pain. These symptoms cannot be attributed to brain, physical diseases and other mental diseases.
Symptoms vary from mild to severe, fluctuations are related to psychosocial factors, and the course of disease is prolonged. In the last century, the concept of neurasthenia experienced a series of changes. With the change of doctors' understanding of neurasthenia and the classification of various special syndromes and subtypes, this diagnosis is no longer made in the United States and western Europe. The field test of CCMD-3 working group proves that the diagnosis of neurasthenia in China has also dropped significantly.
