Hyperkinesis is an extra involuntary movement that can be a self-contained disorder or a sign of another disease.
Hyperkinesis - a large group of motor disorders, the main property of which is the presence of excessive involuntary movements. Hyperkinesis can occur in various diseases of the nervous system, be the result of organic pathology of the nervous system or functional disorders.
Depending on the level of damage to the nervous system and its nature, the clinic of hyperkinesis will also be different. Hyperkinesis can be widespread, with the involvement of all skeletal muscles, or local, local.
There are several types of hyperkinesis.
Dystonia is characterized by pathological poses and violent movements in different parts of the body, more often rotational. In accordance with the degree of capture of skeletal muscles in hyperkinesis distinguish the following types of dystonia: focal, segmental, multifocal, gemidistonia, generalized.
Primary dystonias, in which dystonia is the only symptom, is an independent disease, such as generalized torsion dystonia, spastic cervix.
A tremor is called rhythmic involuntary movements in any part of the body. There is a resting tremor, which is observed in the absence of arbitrary movements in this part of the body, and the tremor of the action that occurs in the implementation of motion and amplifies in the course of movement. Rest Tremor is typical for Parkinson's disease.
The reduction of muscle or muscle groups or the fall of their tone, which are abrupt, short-acting, throbbing-like, is called myoclonus. Allocate positive myoclonus (muscle contraction) and negative (drop of tonus). Myoclonus can be focal, segmental, multifocal, and generalized.
The main features of chorea are rapid, disorderly movements, varying in intensity and amplitude.
These may be movements similar to ordinary gestures, or continuous, large-scale gestures, vocalizations. When chorea in hyperkinesis involves the muscles of the limbs, trunk, throat, larynx, face.
Tyami are called fast, violent, stereotypic movements. Tiki can be motor and vocal. Motor teaks are divided into simple and complex ones. Frequently, ticks are an independent neurological disorder, and not a sign of another disease of the nervous system.
Hyperkinesis as symptoms and complications
Hyperkinesis can be symptoms of diseases of the nervous system such as epilepsy, Parkinson's disease, Wilson's disease - Konovalova, Huntington's disease, homocystinuria, multiple sclerosis.
Hyperkinesis can be complications of various diseases of the nervous system: perinatal CNS damage, craniocerebral trauma, brain tumors, transferred encephalitis, vascular diseases of the nervous system.
Hyperkinesis can also be observed in poisoning, mainly in poisoning with toxicants in the group of convulsants.
