Abnormal movements - Abnormal movements symptom, treatment, causes
Many neurological diseases cause abnormal movements, most of which are involuntary. These can take the form of spasms or repetitive muscular activity resulting in anything from a twitch to a convulsion. Abnormal movements themselves are symptoms of underlying disorders. In some cases, the abnormal movements are the only symptoms.
Abnormal movements primarily affect the extremities, trunk, or jaw . Abnormal movements and tardive dyskinesia and cigarette smoking. The abnormal movement may be reduced or disappear during sleep, but it is worsened by emotional stress. Abnormal and sometimes grotesque postures may be a manifestation of these movements.Abnormal movements were measured using the abnormal involuntary movement. Abnormal movements in sleep as a post-polio sequelae the dopamine autoreceptor agonist 3-PPP were studied in three Cebus apella monkeys with persistent abnormal movements induced by prior long-term treatment.
Some disorders slow movements down, making it difficult for the patient to initiate or sustain an activity. Movement is produced and coordinated by several interacting brain centers, including the motor cortex, the cerebellum, and a group of structures in the inner portions of the brain called the basal ganglia. Sensory information provides critical input on the current position and velocity of body parts, and spinal nerve cells (neurons) help prevent opposing muscle groups from contracting at the same time.
When an abnormal movement is noticed, get your doctor to diagnose its cause immediately. 'Jittery' people may not be clumsy by intent. They could be suffering from a movement disorder.
The same is true of people who appear slow and apathetic. Let your doctor decide what ails them. There are special names for abnormal movements. Slow movements which are often noticed as a peculiar twisting posture or a writhing movement, are called dystonia or athetosis.
Fast, irregular abnormal movements are tics, chorea, myoclonus. Of these, only tics can be voluntarily controlled.
An abnormal restriction or slowing of movement is typical of Parkinson's Disease, where the patient often shows a Buddha-like calm, not because of some inner peace, but because the facial muscles do not allow him to express his inner turmoil. Disorders causing abnormal movements include:
- Parkinson's disease
- Parkinsonism caused by drugs or poisons
- Parkinson-plus syndromes (progressive supranuclear palsy, multiple system atrophy, and cortical-basal ganglionic degeneration)
- Huntington's disease
- Wilson's disease
- Inherited ataxias (Friedreich's ataxia, Machado-Joseph disease, and spinocerebellar ataxias)
- Tourette syndrome and other tic disorders
- Essential tremor
- Restless leg syndrome
- Dystonia
- Stroke
- Cerebral palsy
- Encephalopathies
- Intoxication
- Poisoning by carbon monoxide, cyanide, methanol, or manganese.
