Hyperkinesis is muscle contraction during nerve impulses. When they continue for too long, the condition is called "hyperkinesia syndrome." Childhood hyperactivity disorder (CHD) is a common neurological diagnosis in children that can manifest as sudden body movements (eg, jerking), speech or non-speech tics.
Symptoms of SDH most often occur at the age of 4–7 years, but are not excluded at other ages. They can be either temporary or permanent. SDH is manifested by deterioration in school performance, while children do not experience difficulties in performing everyday activities, such as getting dressed, tying shoelaces, etc. They cannot control impulses to move and do not know what to do with them.
The causes of SDH may be hereditary, psychosocial, or mixed. More than 50% of children with ADHD have a family history of another family member who also has ADHD. The syndrome often occurs in families where there have been difficult or maladaptive psychological conditions, such as psychiatric disorders, violence, abuse or substance abuse. Some children with DDH may have excess activity in the nervous system as a result of genetic defects or disorders during fetal development.
Treatment for SDH includes the use of medications, physical therapy, training in techniques to manage one's emotions and behavior, consultation with a neurologist, and social support. It is important to remind children of the importance of the ability to control their involuntary movements and prevent social manifestations of emotions in the children's social environment.
