What Are the Most Common Causes of Anxiety Disorders?

Anxiety, also known as anxiety neurosis, is the most common type of neurosis, and is characterized by anxiety and emotional experience. Can be divided into two forms of chronic anxiety (generalized anxiety) and acute anxiety (panic attack). The main manifestations are: nervousness without a clear objective object, restlessness, and symptoms of autonomic dysfunction, such as palpitations, hand tremors, sweating, frequent urination, and motor restlessness. Pay attention to distinguish normal anxiety emotions. If the severity of anxiety is clearly inconsistent with objective facts or situations, or if the duration is too long, it may be pathological anxiety.

(4) Easily misdiagnosed When an attack occurs, patients often call the "120" emergency phone to see the emergency department of cardiology. Although the patient appears to be very symptomatic, most of the relevant test results are normal, so the diagnosis is often unclear. After the attack, the patient is still extremely scared and worried about his condition. He often goes to various departments in major hospitals and performs various tests, but the diagnosis cannot be confirmed. Both delay treatment and waste of medical resources.

Anxiety diagnosis

It is mainly diagnosed by a specialist based on medical history, family history, clinical symptoms, course and physical examination, scale test and laboratory-assisted examination. The most important of these are clinical symptoms and disease course.

Early screening or self-diagnosis can use some simple anxiety self-assessment scale (SAS) assessment. If the score is high, it is recommended to go to the psychiatric or psychological department for further examination.

According to the 3rd Edition Chinese Classification and Diagnostic Standard of Mental Disorders (CCMD-3), a subtype of anxiety neurosis must first meet the characteristics of neurosis, that is, it has a certain personality foundation, and its onset is often affected by psychosocial factors The symptoms are not based on a verifiable organic lesion, which is not commensurate with the actual situation of the patient, but the patient is painful and powerless about the existing symptoms, has complete self-knowledge, and has a prolonged course.

Eliminate secondary panic attacks such as phobias, depression, or somatic disorders; exclude secondary panic attacks such as epilepsy, heart attack, pheochromocytoma, hyperthyroidism, or spontaneous hypoglycemia. The characteristics of mild symptoms meet the following 4 points, plus severe symptoms plus point 5:

(1) There is no obvious cause of the attack, and there is no relevant specific scenario, and the attack is unpredictable;

(2) In the intermission period, there are no obvious symptoms except for fear of recurrence;

(3) Strong onset of fear, anxiety, and obvious autonomic symptoms at the onset, and often have painful experiences such as dying fear and sense of loss of control;

(4) The attack begins suddenly and reaches its peak quickly. The consciousness is clear during the attack and can be recalled afterwards.

(5) The patient feels pain because it is unbearable and cannot be relieved. The standard duration of the disease is at least 3 episodes within 1 month, or the anxiety of fear of recurrence after the first episode lasts for 1 month.

2. General anxiety (chronic anxiety)

(2) With autonomic symptoms or motor disturbances.

(3) The social function is impaired, and the patient suffers because it is difficult to bear and cannot be relieved. The course criteria meet the above symptoms for at least 6 months.

Differential diagnosis of anxiety disorder

Normal tension

Normal tension is different from pathological anxiety, and it shows an emotional response to the objective threat of reality. This emotional response is compatible with the actual threat.

2. Anxiety symptoms associated with physical illness

Anxiety secondary to physical illness should be diagnosed as anxiety syndrome. Anxiety manifests in a variety of medical diseases, especially cardiovascular and endocrine diseases.

3. Anxiety symptoms associated with drugs

Due to the widespread use of hormonal drugs, the symptoms of anxiety caused by drugs are no longer rare, as long as the history of medication is not ignored, identification is not difficult. If the diagnosis is suspicious, the hormone should be reduced or discontinued for observation. Cocaine, cannabis, heroin administration or withdrawal can cause anxiety and autonomic dysfunction, and even typical panic attacks. Antipsychotics can cause anxiety.

4. Anxiety symptoms associated with mental illness

If the patient is too old, the dosage is not large, and the effect is better, you can not change the drug. As long as the dosage of tranquilizers does not increase, and within the normal range, the efficacy does not decrease, it can be considered that there is no dependence.

(2) Antidepressants Because the cause of anxiety can lead to disorders of the body's neuro-endocrine system and imbalance of neurotransmitters, antidepressants can make the unbalanced neurotransmitters tend to normal, so that anxiety symptoms disappear and emotions return to normal. General anxiety The commonly used drugs for treatment are paroxetine (Xelortex), escitalopram (Raspor), venlafaxine (Bolexin, Yinuosi), Dilixin and so on.

Drug therapy is the cure, and psychotherapy is the cure. Both are indispensable.

There are also psychotherapy biological feedback treatment and relaxation treatment suitable for anxiety patients.

Anxiety prognosis

The sooner you diagnose and the sooner you treat, the better the prognosis for anxiety. After specialized treatment, the vast majority of patients will get clinical rehabilitation and return to the happy mood of the past.
