Hemiballismus

Chorea and hemiballismus are both forms of involuntary movement disorders. Some health experts may describe hemiballismus as the most severe form of hyperkinetic movement disorder. There are several types and subtypes of Both chorea and hemiballismus are types of these disorders. They can both cause sudden, unwanted movements on one side of the body. Though similar, they have some differences that set them apart. In this article, we will review the differences between chorea and hemiballismus and explore how they differ from athetosis, another involuntary movement disorder. Share on Pinterest Michelle Pallant/EyeEm/Getty Images Chorea and hemiballismus are similar hyperkinetic involuntary movement disorders. Both can cause: • sudden, irregular movements • typically only involve one side of the body • occur due to damage to the brain • may occur to one of several different underlying conditions Experts Chorea can affect several different muscles on the face, trunk, and limbs. Conversely, hemiballismus typically affects one side of the body’s arm or leg. Both conditions occur due to damage to the areas of the brain that control movement. Additionally, overactivity of the chemical dopamine in the brain may also be responsible. Some experts • athetosis causes slow, writhing, or twisting movements • chorea causes abrupt, irregular, and sudden movements that can give the appearance of a dancing motion • ballismus is the most severe form that involves violent flinging of the limb...

The hallmark of hemiballsimus is the development of large-amplitude, involuntary, irregular and violent movement of the limbs on one side of the body [1]. The proximal aspects of the arm and leg are most commonly affected, whereas facial involvement is seen in about 50% of cases [1]. These large-amplitude movements can cause severe […] hemiballismus [ hem″e-bah-liz´mus ] violent motor restlessness of half of the body, most marked in the upper limbs. hem·i·bal·lis·mus ( hem'ē-bal-iz'mŭs ), Ballism involving one side of the body. Typically in tardive dyskinesia there are: (1) chewing and sucking movements or the mouth and tongue (oro-bucco-lingual dyskinesia). (2) thrusting movements of the pelvis, and (3) motor restlessness (also called akathisia). TREMOR Tremor is a universal phenomenon. The description of tremors often relies on an assessment of the tremor frequency: this is hard to judge with the naked eye. We report two cases of post-stroke hemiballismus and contralateral tremor. Both patients presented acute hemiballismus. In one of the patients, the tremor started with acute symptomatology and the other was delayed. No paciente com tremor de Holmes havia lesões no mesencéfalo e no cerebelo, secundárias à co-infecção pelo bacilo da tuberculose e pelo Toxoplasma gondii.

The basal ganglia (caudate nucleus, putamen, globus pallidus, subthalamic nucleus, and substantia nigra) form the extrapyramidal system. They are located deep in the forebrain and rostral midbrain. The basal ganglia direct their output mainly through the thalamus to the cerebral cortex (see figure Basal ganglia ). Two main motor functions are integrated in the basal ganglia: Chorea, Athetosis, and Hemiballismus Chorea is a nonrhythmic, jerky, rapid, nonsuppressible involuntary movement, mostly of the distal muscles and face; movements may be incorporated into semipurposeful acts that mask the involuntary... read more (including hemiballismus [rapid chorea] and athetosis [slow chorea]) • Rhythmic disorders are primarily tremors—regular alternating or oscillatory movements, which can occur mainly at rest, while maintaining a position, and/or during attempted movement. However, in some cases, a tremor, though rhythmic, is irregular, as occurs when tremor is associated with dystonic disorders. Athetosis and chorea may occur together as choreoathetosis. Chorea is the most characteristic movement disorder in Huntington Disease Huntington disease is an autosomal dominant disorder characterized by chorea, neuropsychiatric symptoms, and progressive cognitive deterioration, usually beginning during middle age.
