What are the classifications of insomnia?

  Classification by clinical manifestations
  ① Sleep latency: sleep duration more than 30 minutes;
  ② Sleep maintenance: more than 2 awakenings at night or early awakening in the morning;
  ③ Sleep quality: more nightmares;
  ④ Early awakening, unable to fall back to sleep after waking up;
  ⑤ Total sleep time is less than 6 hours;
  ⑥Daytime residual effects: feeling dizzy, mental weakness, drowsiness and weakness in the next morning.
  Classification by severity
  Mild: Occasional, with little impact on quality of life;
  Moderate: Occurs every night, moderately affects quality of life, with certain symptoms (irritability, anxiety, fatigue, etc.);
  Severe: occurring every night, seriously affecting the quality of life, with prominent clinical symptoms.
  Classification by cycle
  Transient insomnia (less than one week)
  Transient insomnia disorder can occur when experiencing stress, stimulation, excitement, anxiety; when sick; to high altitude; or when sleep patterns change such as jet lag; shift work, etc.).
This type of insomnia usually improves as the event disappears or lengthens over time, but some transient insomnia can lead to chronic insomnia if not handled properly.
  The main principles of treatment for transient insomnia are intermittent use of low-dose sedative sleeping pills or other sleep-aiding medications such as antidepressants and good sleep hygiene practices.
  Short-term insomnia (one week to one month)
  Severe or persistent stress, such as major physical illness or surgery, the death of a close friend or family member, or serious family, work or relationship problems, may cause short-term insomnia. There is a clear correlation between this type of insomnia and stress.
  Treatment is based on the short-term use of low-dose sedative sleeping pills or other sleep-aiding medications such as antidepressants and behavioral therapy (e.g., muscle relaxation). Short-term insomnia can also lead to chronic insomnia if not treated properly.
  Chronic insomnia (greater than one month)
  Chronic insomnia can last for several years. Some people suffer from insomnia when faced with stress (or even just normal stress), just as some people are prone to chronic gastritis or migraines and have developed a habitual pattern of stress.
  Classification by time
  1.It occurs at the early stage of sleep and manifests itself as very difficult to fall asleep, and is the most common form of insomnia.
  2.It is manifested as waking up and sleeping at times throughout the night.
  3.It occurs at the end of sleep, when the patient wakes up too early and cannot fall back to sleep. All these patients have less heterophasic sleep and are prone to induce arousal response of EEG. The consequences of insomnia are not serious. Long-term insomniacs are sometimes mentally depressed and can be corrected by medication.
  Initial sleep: i.e., they cannot fall asleep at the beginning of sleep, that is, they do not sleep easily and fall asleep slowly, and fall asleep only in the latter half of the night when it is almost dawn. Most of them are caused by tension, anxiety, anxiety and fear in life.
  End point sleep: i.e., no difficulty in falling asleep, but it does not last long and cannot fall asleep again after waking up in the second half of the night. It is an inevitable phenomenon of high age, often occurs in hypertension and vascular sclerosis, and mental depression often occurs with such insomnia.
  Classification of chronic insomnia
  Clinical classification of chronic insomnia into primary insomnia and secondary insomnia.
  1, primary insomnia: is an unexplained, long-term or lifelong presence of frequent sleep interruptions, short sleep with daytime fatigue, tension, depression and sleepiness. In addition to other intrinsic causes and environmental disturbances, some patients may have a family history of insomnia. The etiology is unknown but the most progressive chronic psychosomatic insomnia.
  2, secondary insomnia: insomnia caused by pain, cough, dyspnea, nocturnal polyuria, angina and other physical fatigue and symptoms. Many metabolic diseases can cause changes in sleep structure and interfere with normal sleep.
