Because hepatitis B is a contagious disease caused by the hepatitis B virus, because there is no effective drug eradication, so that some patients do not heal, or even deteriorate or cancer, often make people “talk about liver”, coupled with work, study, family, marriage and other invisible obstacles, as well as the invisible hand of society, will inevitably cause Some patients with poor psychological quality appear more serious psychological disorders, here I will only hepatitis B patients in one of the most common symptoms of neurosis “neurasthenia” performance is summarized below, for the reader’s reference. Neurosis, also known as neurosis, or psychoneurosis, is a general term for a group of milder brain dysfunctions. Neurosis can be divided into neurasthenia, hysteria, anxiety, obsessive-compulsive disorder, phobia, neurotic depression and hypochondria, each of which has its own clinical point, but they have common points, as shown in: the onset of the disease is often closely related to the spirit; unhealthy personality characteristics often become the basis for the onset of the disease; a variety of symptoms, whether manifested in the mental, neurological or somatic aspects, can not be detected in the corresponding pathological anatomical changes; the personality remains intact, good contact with reality. Personality remains intact, in good contact with reality, still maintaining some or all of the ability to socialize, live and work; self-awareness of the disease and request for treatment. Neurosis is characterized by chronic fatigue, emotional instability, disturbance of plant nerve function and accentuated by excitement and ease of fatigue or exhaustion, and is accompanied by many somatic symptoms and sleep disorders. Research data illustrates that; adverse emotions, are often the causative factor of neurasthenia. Other common causes are: death of a loved one, family discord, career failure, tension with leaders and colleagues, and various setbacks in life and other mental tension stimuli. The emotional experiences of worry, anger, resentment, aggression and sadness caused by these stressful stimuli lead to dysfunctional cortical nerve activity and neurasthenia. At the same time, such as suffering from infection, poisoning, cranial trauma, maternal hemorrhage, long-term insomnia, or other factors that weaken the function of the body, can contribute to the occurrence of neurasthenia. Most patients with neurasthenia have physical and personality characteristics. Some scholars have noted that most of these patients belong to the weak type with a long, thin body and weak muscles. The personality of these patients is more on the side of cheerless, sensitive and suspicious, subjective and impatient and poor self-control. However, there are a few exceptions. Except for a few people caused by excessive mental stimulation, neurasthenia is usually not caused by a single factor, but is the result of a combination of adverse emotional experiences, unhealthy personality traits and weakened functional conditions of the body. The pathogenesis of the disease lies mainly in the aforementioned stressful stimuli that cause excessive tension in the excitatory or inhibitory processes of higher neural activity, or a conflict between the two, resulting in a weakening of the internal inhibitory processes and a relative hyperactivity of the excitatory processes. The weakening of the internal inhibitory processes, in turn, reduces the recovery capacity of the nerve cells, resulting in easy exhaustion. The weakening of the cerebral cortex weakens the regulation of the subcortical vegetative nerve centers, and a disturbance of the vegetative nerve function occurs. Clinical manifestations; most of them are slow onset, with complex and diverse symptoms, mental symptoms and somatic symptoms often appear simultaneously, and the symptoms are inconsistent depending on the characteristics of each individual. I. Easily excited and provoked; self-control is reduced, temperament becomes impatient and easily agitated, and mood is obviously unstable. Patients often become angry or sad, tearful, and unable to restrain themselves because of trivial matters. Due to increased excitability, the patient is on edge all day and speaks and behaves in a hurry. Attention is also difficult to concentrate. The patient is particularly sensitive and averse to external sounds, bright lights or unpleasant smells. It is not easy to rest calmly because of the distracting thoughts and changing emotions. Before going to bed, you often cannot fall asleep because of excitement and irritability. Even if they do fall asleep, the sleep is shallow and dreams are particularly frequent, so patients still feel fatigued when they wake up in the morning and, on the contrary, feel less symptomatic at night. Second, easily fatigued and exhausted; the patient is easily excited and aroused, but with it comes exhaustion. Dizziness, dizziness, and even inability to persist after thinking about problems with the brain for a little while. A similar situation occurs with other activities, but is more pronounced with mental activities. Active attention is weakened and becomes worse with time, thus affecting near memory and making it more difficult to remember numbers and names. When the disease progresses to a severe stage, the patient may experience generalized weakness. The most common clinical manifestation of hepatitis B patients is weakness of the limbs, which will become more pronounced here. Third, somatic symptoms; due to the increased excitability of the nervous system, the perceptiveness of the receptors and endoreceptors is also enhanced. Patients often have dizziness and pain or head tightening sensation. The senses of touch, pain and temperature are also abnormally sensitive, and the slightest stimulus is unbearable. As a result of increased endoreception, visceral activities that are not usually easily perceived are sensed, such as palpitations, pain in the precordial region, or peristalsis in the gastrointestinal tract. For hepatitis patients performance such as swelling sensation in the liver area, tingling sensation, obvious enlargement of the liver and other manifestations. Phytodysfunction, tachycardia, high or low blood pressure, excessive sweating, cold extremities, diarrhea, constipation, frequent urination, seminal emission, premature ejaculation, impotence, or menstrual disorders, etc. may occur. Fourth, the pathological psychological reaction; each person has different feelings about the symptoms, and therefore different reactions. Most people have a tendency to be suspicious, such as suspecting organic lesions in the brain because of headache, dizziness and memory loss, or suspecting heart disease because of palpitations, or worrying about incurable diseases because the treatment is not effective for a while. For patients with hepatitis B, some discomfort in the body is usually attributed to the hepatitis B virus, without a proper understanding. Always beware of the progress of the disease or whether it is worsening. It is because of the concerns and worries about the disease that cause anxiety and nervousness and fear, which aggravate the original disease. This is repeated again and again, forming a vicious cycle that complicates the clinical manifestations. This pathological psychological reaction is often influenced by the patient’s subjective opinion, personality characteristics and the attitude of the surrounding people.
