Chorea, Athetosis And Hemiballism

Chorea is a non-rhythmic, quivering, quick, nichtunterdrückbare involuntary movement, usually the distal muscles and the face; the movements can be included in targeted effective actions that mask the involuntary movements. Athetosis (slow chorea) is not rhythmic, slow, spiraling, screwing movements primarily in the distal muscles, often alternating with stances of the proximal extremities. Hemiballismus is a unilateral fast, non-rhythmical, nichtunterdrückbare, wild slinging motion of the proximal arm and / or leg; rarely such a movement occurs bilaterally (Ballismus). Hemiballism can be berachtet as a severe form of chorea.

Chorea and athetosis be defined by clinical manifestations; Many experts believe that their common occurrence (as choreoathetosis) the athetosis is a dystonia, overlying the Chorea. Chorea and athetosis are the result of the limited inhibition of the thalamocortical neurons through the basal ganglia. The mechanism may be due to an excessive dopaminergic activity.

Chorea and athetosis are the result of the limited inhibition of the thalamocortical neurons through the basal ganglia. The mechanism may be due to an excessive dopaminergic activity. Whenever possible, doctors should look for the cause of chorea and treat. M. Huntington is the most common degenerative disorder that causes choreatic symptoms. In M. Huntington drugs that suppress the dopaminergic activity may as antipsychotics (eg. As Risperidone, Olanzapine) and dopamine depleting drugs (eg. As reserpine, tetrabenazine) are used for the treatment of chorea. Antipsychotics can also help by attenuate the neuropsychiatric symptoms that are associated generally with Huntington’s disease (z. B. impulsivity, anxiety, psychotic behavior) However, limits the improvement and be temporary. These drugs can reasonably be used to treat chorea without definable cause. Other causes of Huntington’s disease are hyperthyroidism, hypoparathyroidism, hyperglycemia, oral contraceptive use, pregnancy, SLE (affecting the central nervous system, medications / drugs (eg. As levodopa in patients with Parkinson’s disease, phenytoin, cocaine), tardive dyskinesia due to conventional and most atypical antipsychotics), autoimmune diseases and paraneoplastic syndromes. Sydenham chorea may occur in rheumatic fever and be the first symptom. A tumor or infarction in the striatum (caudate nucleus or putamen), acute unilateral chorea (hemichorea) cause. Sydenham chorea and chorea due to infarction of the caudate nucleus often go over time without treatment. Chorea due to hyperthyroidism or other metabolic cause (z. B. hyperglycemia) sinks in general, if the function of the thyroid gland or the blood sugar levels are normalized. Senile Chorea is a type of chorea that> 60 years occurs in patients; they tend to affect the oral and perioral muscles. Senile Chorea is diagnosed when chorea occurs as an isolated symptom. No other cause can be identified. Chorea is not progressive. No dementia is present. In many cases, seemingly senile chorea a special investigation identified symptomatic cause of chorea (. Eg toxic, metabolic, autoimmune); in all patients symptomatic causes should be ruled out. Chorea gravidarum occurs during pregnancy, often in patients who had previously had rheumatic fever. Chorea usually begins during the first trimester and disappears spontaneously at or after birth. If treatment before birth is necessary because the chorea is severe, barbiturates are displayed, because they have less fetal risks than other medications for control of chorea. Rarely occurs in a similar disorder in women taking oral contraceptives. Hemiballismus, is caused by a lesion, usually an infarct, which is located in the subthalamic nucleus or the contralateral. A Hemiballism Although disabling, but he limited himself and lasts about 6-8 weeks. In severe cases can be treated with antipsychotic 1-2 months.
