sleep paralysis
Introduction
Introduction This is medically called "nightmare (eye)", also known as the "ghost press". Like dreaming, nightmares are also a physiological phenomenon. When a person suddenly wakes up, a part of the nerve center of the brain has awakened, but the nerve center that dominates the muscle has not fully woken up, so although there is an uncomfortable feeling, it cannot move. At this time, if someone wakes him or pushes him One, the nightmare will disappear immediately. The decline in sleep quality is a common complaint, and the number of long-term sleep disorders in the adult population can be as high as 15%.
Cause
Cause
Sleep paralysis syndrome is usually produced during sleep. It can block our ability to act. It is that we don't really act in our dreams to avoid hurting ourselves. In general, sleep paralysis will fade after we wake up. It is believed that the main "sleep regulation center" is located in the ventral region of the hypothalamus, that is, the suprachiasmatic nucleus. In addition to causing disturbances in the sleep-wake cycle, this area of the disease can also cause changes in body temperature and eating activity. Sleep-related anatomy is quite extensive, including at least the frontal lobe and the ankle cortex. The suprachiasmatic nucleus, the giant cell area of the midbrain cover, the blue spot, the interstitial nucleus, the medullary reticular formation inhibition zone, and the ascending reticular system.

Polysomnography check EEG examination
Various scales such as the Epworth Sleep Scale (ESS); nocturnal polysomnographic recordings (NPSG) records; the Multi Sleep Latency Test (MSLT) and the like.
NPSG is best for evaluating endogenous sleep disorders such as obstructive sleep apnea syndrome and periodic leg movements or frequent deep sleep conditions such as REM behavioral disorders or nighttime head movements. There is no benefit in the evaluation of insomnia, especially insomnia, which is mainly difficult to fall asleep.
MSLT is often performed after NPSG to assess oversleeping. This method often finds daytime excessive sleep in narcolepsy and REM in the early stages of sleep. MSLT should be performed during the patient's normal awake cycle and then observe a normal night's sleep.
