Myoclonus and chorea are hyperkinetic movement disorders that confer a jerky appearance. Myoclonus involves a quick and simple jerk, whereas the jerking in chorea combines with other, slower movements in a continuous, flowing fashion.
What is the difference between chorea and ataxia?
Unlike ataxia, which affects the quality of voluntary movements, or Parkinsonism, which is a hindrance of voluntary movements, the movements of chorea and ballism occur on their own, without conscious effort. Thus, chorea is said to be a hyperkinetic movement disorder.
What does Athetosis look like?
Athetosis is a symptom characterized by slow, involuntary, convoluted, writhing movements of the fingers, hands, toes, and feet and in some cases, arms, legs, neck and tongue. Movements typical of athetosis are sometimes called athetoid movements.
How is Athetosis treated?
Treatment of athetosis
These include: anti-dopamine medicines: drugs that suppress the hormone’s effect on the brain. Botox injections: treatment that may temporarily limit involuntary muscle actions. occupational therapy: muscle training to regain some control.
What causes Choreoathetoids?
All the causes of choreoathetosis overstimulate an area of the brain called the basal ganglia. Similar to the way that someone might vomit for a variety of reasons, choreoathetosis is a response to stress or trauma on the body. Choreoathetosis can be caused by any of these conditions: Huntington’s disease.
What is chorea Athetosis?
Chorea typically involves the face, mouth, trunk, and limbs. Athetosis is a continuous stream of slow, flowing, writhing involuntary movements. It usually affects the hands and feet. Hemiballismus is a type of chorea, usually involving violent, involuntary flinging of one arm and/or one leg.

Is chorea a type of dyskinesia?
Dyskinesia refers to a category of movement disorders that are characterized by involuntary muscle movements, including movements similar to tics or chorea and diminished voluntary movements.
Can chorea go away?

Where is the lesion in chorea?
The most consistent biochemical lesion in patients with Huntington chorea appears to be a loss of neurons in the basal ganglia that synthesize and contain GABA.
What does chorea feel like?
Chorea is a movement disorder that causes involuntary, unpredictable body movements. Chorea symptoms can range from minor movements, such as fidgeting, to severe uncontrolled arm and leg movements.
What is Athetoid?
Dyskinetic CP (also called athetoid CP) is one type of cerebral palsy. Kids with dyskinetic CP have trouble controlling muscle movement. They have twisting, abrupt movements. Other types of cerebral palsy can lead to stiff muscles (spastic CP) or problems with balance and walking (ataxic CP).

- Poor posture.
- Unsteadiness.
- Twisting of the torso.
- Slow, writhing movements.
- Abrupt movements.
- Grimacing or drooling.

What is St Vitus dance?
Sydenham chorea, also called St. Vitus Dance, chorea minor, infectious chorea, or rheumatic chorea, a neurological disorder characterized by irregular and involuntary movements of muscle groups in various parts of the body that follow streptococcal infection.
What is a chorea episode?
Chorea causes fast, unpredictable muscle contractions like fidgeting, or arm and leg movements. Chorea mostly affects the face, limbs or trunk of the body. Athetosis causes slow writhing movements, typically of the hands and feet. Choreoathetosis can affect people of any age or gender.

What is the difference between bradykinesia and akinesia?
