Habit choreas, also known as chronic motor stereotypies, is a neurological disorder characterized by repetitive, purposeless movements predominantly affecting the upper body. These movements may include hand flapping, arm waving, head nodding, body rocking, and similar repetitive gestures. Habit choreas typically begin in childhood, often around the age of 2 to 4 years, and may continue into adolescence and adulthood.
The specific cause of habit choreas is unknown, although it is believed to arise from a combination of genetic and environmental factors. Individuals with habit choreas generally have normal intelligence and do not experience any cognitive impairment. The condition is usually not associated with any underlying neurological or psychiatric disorders.
Habit choreas are considered voluntary movements that are performed unconsciously and without any purpose. The movements are typically stereotyped, meaning they are repetitive and consistent in form. They can vary in intensity, frequency, and duration throughout the day, and may be temporarily suppressed during times of intense focus or concentration.
Although habit choreas do not cause significant physical discomfort or pain, they can pose challenges in social situations and may interfere with activities of daily living. Treatment options for habit choreas include behavioral interventions, such as habit reversal therapy, as well as medication management aimed at reducing the frequency and severity of the movements.
In summary, habit choreas are a neurological condition characterized by repetitive, purposeless movements primarily affecting the upper body. They typically begin in childhood and may persist into adulthood. While not associated with cognitive impairment, habit choreas can present challenges in daily life and may require treatment to manage symptoms.
