What causes Athetosis?

Causes. Athetosis is a symptom primarily caused by the marbling, or degeneration of the basal ganglia. This degeneration is most commonly caused by complications at birth or by Huntington’s disease, in addition to rare cases in which the damage may also arise later in life due to stroke or trauma.

What is Athetosis in cerebral palsy?

Athetoid cerebral palsy (also known as “dyskinetic cerebral palsy”) is a movement disorder caused by damage to the developing brain. This type of cerebral palsy is characterized by abnormal, involuntary movement. Children with athetoid CP fluctuate between hypertonia and hypotonia.

What is Athetosis disorder?

How does chorea affect the body?

Speech problems: Kids and adults may develop slurred speech as the muscles involved in making speech lose coordination. Headaches and seizures: Kids who develop chorea after rheumatic fever can have seizures and headaches. Some children also have behavioral and emotional issues.

What is the treatment for chorea?

Doctors prescribe deutetrabenazine (Austedo®) or tetrabenazine (Xenazine®) to control muscle movements of Huntington’s chorea. If chorea is part of a tardive dyskinesia syndrome, the medications valbenazine (Ingrezza®) and deutetrabenazine are usually considered.

What is the difference between chorea and Athetosis?

Chorea is an ongoing random-appearing sequence of one or more discrete involuntary movements or movement fragments. Athetosis is a slow, continuous, involuntary writhing movement that prevents maintenance of a stable posture.

What happens to a baby with athetosis during birth?

If a baby is cut off from air supply during birth, their risk for developing athetosis is higher. Asphyxia, or a lack of sufficient oxygen levels, can damage the brain. It also cuts off the supply of necessary nutrients and increases dopamine levels in the brain. These effects may damage the basal ganglia.

What causes a person to have symptoms of athetosis?

Drugs that increase levels of dopamine in the brain may damage the basal ganglia and cause symptoms of athetosis. Athetosis may also occur after a stroke or trauma in adults. Damage to the brain may interfere with neuron movement. This can lead to symptoms of athetosis and other movement disorders.

Is there a symptom of cerebral palsy called athetosis?

Athetosis is a commonly occurring symptom in the disease cerebral palsy. Of all people with the disease, between 16% and 25% of them actually exhibit the symptom of athetosis. A component of this is the finding that most often the symptoms that involve athetosis occur as a part of choreoathetosis as opposed to athetosis alone.

What’s the difference between athetosis and chorea?

Athetosis and chorea are very similar. In fact, they can occur together. When they do, they’re jointly called choreoathetosis.
