What is the delayed sleep syndrome?

Just as that sounds, the delayed sleep syndrome is a disorder that occurs when a person can not fall asleep regularly after his desired sleep. Those who experience this syndrome often take two or more hours than falls asleep, which not only often leads to awakening at the desired time, but often also leads to insufficient rest. It is considered to be a weakening disorder, because suffering sleep patterns do not follow normal circadian rhythm, a biological cycle of the body, which usually repeats at 24 -hour intervals. Due to the inability of sleep at night, suffering from a delayed sleep syndrome, often too sleepy during the day, disrupts their work or school. Symptoms include insomnia, lots of energy during the evening and excessive daily drowsiness. The effects of the delayed sleep phase include irritability, depression and sleep depression. Syndrome differs from insomnia in patients with Delayed Sleep Phase tend to fall asleep almost at the same time every night/morning without bendDu on when they go to sleep.

The delayed sleep phase syndrome often begins in adolescence; Although some cases start in childhood. It is rare that it begins with someone older 30. Similar symptoms, but not the syndrome itself, can be caused by an event such as staying all night to study or party, or to exchange work.

Most patients experience calm, sound sleep and awaken normally if they receive the appropriate number of hours of sleep. These patients are often described as "night owls" or "night people" because of their alertness and a high level of energy, which usually occurs in later evening and night hours.

There are many possible treatments for the delayed sleep phase syndrome. Exposure to bright light in the early morning hours can be useful. This light therapy is Similk that is used for those with seasonal affective disorders.

ChronoterPie is the process of moving before bedtime later three hours every 24 -hour period until the patient reaches the desired sleep. Other patients found benefits of melatonin or vitamin B12. Patients generally do not find long -term success, using relaxation techniques or sleeping pills. In fact, the use of sleeping pills can worsen drowsiness problems.

Since there is no diagnostic test to determine the delayed phase syndrome, the doctor takes the patient's sleep history. The patient should maintain a sleep diary so that doctors can provide accurate and long -term information. Symptoms must usually persist for at least a month for diagnosis, but often symptoms persist much longer.
