General dystonia

Dystonia refers to dyskinesias that are characterized by abnormal movements and postures of muscle tone caused by uncoordinated or excessive contraction of active and antagonist muscle contractions. General dystonia: refers to dystonia of three or more head, neck, limb, and trunk muscle groups, such as torsion spasm. Dystonia can be classified as systemic, focal, or segmental. General dystonia (deformative dystonia, formerly known as torsional spasm) is a rare progressive syndrome that is characterized by torsional involuntary movements resulting in a continuous, often weird, posture. Symptoms usually begin Appeared in childhood. Appears as foot inversion and fixed in plantar flexion while walking. Systemic dystonia is often hereditary. The main genetic pattern is autosomal dominant heredity with partial penetrance. Some members of the family of a prior patient who appear to be "not diseased" are often frustrated cases of this disease. . In several families, the causative gene appears to be localized to chromosome 9q. The pathological anatomy of this disease is unknown. The most severe form of the disease shows an unforgiving and steadily progressing course of the disease. Cases with very severe symptoms may often be in a peculiar fixed posture formed by whole-body torsion. Mental and thinking functions usually remain normal. The child has a noticeable abnormal posture distortion and involuntary change of movement. Postural torsion causes abnormal postures, including twisting the neck and leaning backwards, twisting both upper limbs and stretching backwards, and spasm and flexion when holding the hand. Diversified, disappear when lying down. Complete remission after sleep. Localization of dystonia due to dysfunction of skeletal muscles and antagonists caused by basal ganglia damage. Presented as systemic dystonia, also known as torsion spasm. Focal dystonia affects only a single body part. Rarely, dystonia can spread to adjacent body parts, forming segmental dystonia, and more rarely, it can further expand into systemic dystonia. There are also certain dystonia syndromes.
