About the Symptom
Stereotypic movement disorder is a condition in which a person engages in repetitive, often rhythmic, but purposeless movements. The exact cause is usually unknown but movements tend to increase if the person is stressed, frustrated, or bored. Some things which have been known to cause the disorder are certain physical conditions, head injuries, and certain drugs (such as cocaine).
When to see a doctor
Seek professional care if you experience any of the following symptoms
Repetitive movements
Related serious diseases
Sometimes, Repetitive movements may be related to these serious diseases:
A type of epilepsy (recurrent seizures) that occurs in young children. These are more commonly called infantile spasms (IS) because they are seen most often in the first year of life, typically between ages 4 and 8 months. They often look like a sudden bending forward of the body with stiffening of the arms and legs lasting for one to two seconds; some children arch their backs as they extend their arms and legs. Spasms tend to happen when the infant wakes up, and often happen in many clusters, with hundreds of seizures per day. It results from damage to the developing brain, with various causes like chromosomal abnormalities (e.g. Down's syndrome), brain malformations, or brain infections.
