Dance-like movement

Introduction Paroxysmal dance, hand and foot akinesia, that is, involuntary motor syndrome, paroxysmal dance, and motion-like epilepsy, also known as exercise-induced epilepsy, paroxysmal dystonia, hand-foot-motion hyperactivity disorder, familial paroxysmal ADHD, Focal motor-borne paroxysmal dance of hand and foot hyperactivity disorder, secondary paroxysmal ADHD. This symptom is a hereditary, paroxysmal disease that is extremely rare from childhood.

Cause

This symptom is an autosomal dominant hereditary disease. Different types of causes, such as paroxysmaldystonic choreoathetosis (PDC), are rare hereditary dyskinesias. Paroxysmal kinesigenic choreoathetosis (PKC) is a rare dyskinesia disease that is often induced by exercise and sometimes associated with diffuse or focal brain injury. It is also considered to be epilepsy. In one form, anti-epileptic treatment is effective because of similar causes of seizures. The cause of seizures is often sudden activity, fatigue, and high concentration of attention.

1. In childhood, there is a family history of the first onset of childhood, most of the family reported by Feng, 7 to 9 years old, a small number of 13 to 15 years old onset. There is a family history, mostly autosomal dominant inheritance.

2. There are many induced factors such as sudden activity, fatigue, nervousness, excitement, and high concentration of attention.

3. There are often short-lived sensory auras before the onset of seizures, such as floating sense.

4. The main manifestations of seizures at the time of attack are limbs, body involuntary convulsions, writhing, unstable standing and strange postures.

5. The duration of each episode is less than 10 s, but it can occur multiple times a day.

6. Unconscious loss of unconscious loss, seizure interval is completely normal.

7. There may be incomplete self-control ability after multiple episodes, some patients can find ways to avoid or reduce the onset.

8. There is a tendency to self-remission after entering the elderly.

9. Does not affect the intelligent development Although it starts from childhood, but has no effect on the child's intelligent development. One of Feng's 11 cases has a doctoral student and three college students.

10. Anti-epileptic drugs are effective in this disease, but various anti-epileptic drugs often have good curative effect.

According to the above clinical features, intermittent symptoms, muscle tension in the onset, rigidity, dance, hand movements, movement, consciousness, family history, etc., can make a diagnosis.

Differential diagnosis

1. Rickets: It is often misdiagnosed as a rickety before it is poorly understood. The paroxysmal dance of hand-foot-and-shoulder syndrome occurs in childhood, with special causes of seizures, short episodes, obvious family history, and suggestive treatment ineffectiveness, which can be distinguished from rickets.

2. Epilepsy: episodes of unconscious disturbances in the onset of hand and foot Xu Mou syndrome can be distinguished from epilepsy and small seizures.

3. Others: In addition, it needs to be differentiated from reflex epilepsy, cataplexy, hand and foot snoring, acute and chronic chorea, congenital myotonia and periodic familial palsy.
