Introduction

Introduction Sleep is a physiological phenomenon in which the brain's advanced nervous system produces universal inhibition. It is a process from shallow to deep. When a person just falls asleep, he is in a relatively shallow state of sleep, that is, he is in a state of paralysis. Some of the nerve cells in the cerebral cortex have been suppressed, and some of them have not yet been completely suppressed. At this time, some excitatory information existing inside and outside the body can interfere with the inhibition of the cerebral cortex and produce an inanimate neural reflex; if this reflex occurs in the motor nerve, causing local muscle contraction in the extremities, sudden movement of the hands and feet will occur. This is the startle of sleep.

Cause

Cause

There are many children who are shocked during sleep. This is because the child has frequent excitatory activities during the day. The nerve cells that direct movement during sleep are not easily suppressed, and the remaining excitatory information is reflected to the cerebral cortex, which interferes with sleep inhibition. Adults are shocked and sleepy, mostly related to factors such as excessive fatigue, excitement, nervousness, anxiety, panic during the day, or the consumption of stimulating beverages before going to sleep.

When you have just fallen asleep and are not fully asleep, your limbs will involuntarily twitch, and even make people suddenly wake up.

Differential diagnosis

Need to be identified with the following symptoms:

Excessive startle response: Excessive startle response refers to excessive stress, mental allergy, and easy to cause a shocking response due to accidental stimulation (such as sudden closing of the door).

Consternation: Commonly known as cramps, convulsions or convulsions, it is one of the common emergency symptoms in childhood. It often occurs in diseases caused by bacteria and viruses. It can be found in high fever and convulsions caused by high fever and cold. It is found in toxic bacillary dysentery and various encephalitis and meningitis. Another type of convulsion is a disease that is neither accompanied by fever or infection, such as low calcium cramps, infantile spasms, and hypoglycemia. It is worth noting that some premature and artificially fed children are more likely to have low calcium cramps due to lack of reasonable feeding. If they occur at night, they often cause accidents. Low calcium cramps are completely preventable as long as the cod liver oil and calcium powder are increased early (half month to one month after birth).
