What is convulsion? These clinical manifestations are all considered convulsions!

Occasional twitching is a "self" reaction of the muscles. It is a normal phenomenon and you don't need to worry too much. If a man twitches frequently, it may be a disease. However, many men don't know much about this disease. It doesn't matter. Today, let's talk about what twitching is and what are its clinical manifestations.

1. Systemic tonic convulsions:

The muscles of the whole body are rigid and twitching, with opisthotonos (the head is tilted back and the whole body is bent backward in a bow shape), the eyes are rolled up or staring, and the patient is unconscious.

2. Localized convulsions:

Only local muscle twitching, such as twitching of only one side of the limb, or twitching of facial muscles, or twitching of fingers and toes, or eye movement, nystagmus, blinking, staring, etc. Most of them are unconscious. The above convulsions can last for a few seconds or minutes, and in severe cases, they can last for several minutes or recur. Seizures lasting more than 30 minutes are called continuous state of convulsion.

3. High fever and syncope:

It is mainly seen in children aged 6 months to 4 years who have convulsions during high fever. The high fever convulsion is short-lived, and consciousness recovers quickly after the convulsion. It often occurs in the early stage of fever. In a fever, there is often only one convulsion. Brain diseases and other serious diseases can be ruled out, and the EEG is normal one week after the fever subsides.

Shock:

It is a common involuntary movement, which is a tonic and convulsive convulsion of the whole body or local muscle groups. It can be generalized like epileptic seizures and localized like focal seizures. Seizures may be accompanied by or without impaired consciousness.

Tonic spasm:

It refers to a tonic contraction of muscles, such as the tonic phase of a grand mal seizure, the intramuscular spasms of the hands and feet in tetany, and the lockjaw and opisthotonos in tetanus.

Muscle spasms:

A short, rapid, electric shock-like, repetitive muscle contraction may occur in several muscle groups or in some muscles. A myoclonus may be so mild that it does not cause movement of a part of the body, or it may be so violent that the patient falls.

Tremor:

It is a rhythmic alternating movement of the agonist and antagonist muscles of the joints. The amplitude can be large or small, and the speed can be fast or slow, depending on the disease. Common parts of tremor are the fingers, jaw, lips and head.

Dance-like movements:

It is a sudden, rapid, amorphous, purposeless, coarse muscle twitching, most commonly seen in the head, face and upper limbs, especially the distal ends of the limbs.

Athetosis:

It refers to the relatively slow twisting movement of the fingers or toes, which manifests in various strange shapes and its speed is between dance movements and torso spasms.

Torsion spasm:

It is a slow twisting movement of the proximal limbs and spinal muscles, also caused by basal ganglia disease. Fasciculation is an extremely rapid and brief contraction limited to certain muscle bundles, without joint movement, which can be induced by manual stimulation of the affected area.
