Hemiballismus or hemiballism is a basal ganglia syndrome resulting from damage to the subthalamic nucleus in the basal ganglia. [1] It is a rare hyperkinetic movement disorder, [2] that is characterized by pronounced involuntary limb movements [1] [3] on one side of the body [4] and can cause significant disability. [5]
The feeling experienced by the individual is described as uncontrollable jolts common to receiving a mild electric shock. [5] The sudden jerks and twitching of the body can often be so severe that it can cause a small child to fall. A myoclonic seizure (myo "muscle", clonic "jerk") is a sudden involuntary contraction of muscle groups. The ...
Late-onset dyskinesia, also known as tardive dyskinesia, occurs after long-term treatment with an antipsychotic drug such as haloperidol (Haldol) or amoxapine (Asendin). The symptoms include tremors and writhing movements of the body and limbs, and abnormal movements in the face, mouth, and tongue – including involuntary lip smacking, repetitive pouting of the lips, and tongue protrusions.
Symptoms: Involuntary, repetitive body movements [1] Causes: Neuroleptic medications (antipsychotics), metoclopramide [1] [2] Diagnostic method: Based on symptoms after ruling out other potential causes [1] Differential diagnosis: Huntington's disease, cerebral palsy, Tourette syndrome, dystonia [2] Prevention: Using lowest possible dose of ...
The amount of time that passes between stroke event and presentation of hyperkinesia depends on the type of hyperkinetic movement since their pathologies slightly differ. Chorea tends to affect older stroke survivors while dystonia tends to affect younger ones. Men and women have an equal chance of developing the hyperkinetic movements after ...
This is characterized by attacks of involuntary movements (dystonia, chorea, or ballism), which are typically triggered by sudden voluntary movements, but can also be triggered by involuntary movements as well (for example, hyperventilating). These voluntary movements usually involve whole body activity such as standing, walking, and running.
Over the period of time leading into the late 20th century, the definition of athetosis was expanded to include movements of the neck, tongue, face, and even the trunk. Along with the expansion of the symptoms came the recognition that it was a part of many medical conditions, including cerebral palsy and stroke. [23]
Motor disorders are malfunctions of the nervous system that cause involuntary or uncontrollable movements or actions of the body. [3] These disorders can cause lack of intended movement or an excess of involuntary movement. [4] Symptoms of motor disorders include tremors, jerks, twitches, spasms, contractions, or gait problems.
