People show many kinds of peculiar behavior. Sometimes their certain actions are very weird and very hard to understand. They get engaged in such kind of activities that has no relevance and feels very strange as well as odd. They continuously do such thing and find it very hard to have a control over it. This sometimes not only creates inconvenience for them but also sometimes becomes very irritating for others. But the dilemma is that, it is not that they are doing such thing on their own but it is a result of a disorder that is compelling them to do such thing. This is typically known as Stereotypic movement disorder.
This disorder is a condition in which the person engages in repetitive, often rhythmic but purposeless movements. In some of the cases, it may even cause self injury. Children who suffer from the problem of Stereotypic movement disorder cannot stop themselves from engaging in repetitive and nonfunctional motor behavior. This can happen in the elder people as well. People with this kind of disorder may wave their hands, rock back and forth, twiddle their thumbs, twirl objects or kick their legs.
In the most severe case, they may also include activities like banging their heads on the wall mainly on the hard surfaces, slapping and punching themselves, self biting, nail biting, picking at the skin and mouthing of objects. Such kind of behavior often causes bruises, cuts, bleeding, infection and some more serious injuries to the patient themselves. Such kind of behavior is often found too irresistible and the children are not able to keep themselves from engaging in such activity for long.
What exactly causes the problem of Stereotypic movement disorder is not known yet. But it is assumed that such kind of behavior tends to get increased if the person is stressed, frustrated, or bored. Sometimes this kind of behavior is also triggered due to some physical injury like head injury or due to abuse of drugs. This disorder mainly affects the children with neurological disorders or mental retardation. This problem can happen at any given age and it can happen to both the boys as well as the girls. The other theory that refers to the cause of Stereotypic movement disorder is because of sensory deprivation, drug use, brain disease, psychiatric disorders and also due to the issue of mental retardation.
In case the symptoms of Stereotypic movement disorder are present, the doctor will do a full evaluation which includes complete medical history of the person and also physical examination of the patient. There is no specific lab test available to diagnose the problem. The doctor may use other kind of tests such as blood tests in order to rule out physical illness or some kind of medical side effects. The most common treatment that is used to treat this problem is aimed at reducing stress that triggers the erratic movements and changing behavior. Relaxation techniques are also used in order to teach the children to resist the urge of Stereotypic movement disorder. In some cases medical help is also taken.
