They include movement dysfunction such as dystonia (continuous spasms and muscle contractions), akathisia (may manifest as motor restlessness), [1] parkinsonism characteristic symptoms such as rigidity, bradykinesia (slowness of movement), tremor, and tardive dyskinesia (irregular, jerky movements). [2]
Parkinsonism is a clinical syndrome characterized by tremor, bradykinesia (slowed movements), rigidity, and postural instability. [1] [2] Both hypokinetic (bradykinesia and akinesia) as well as hyperkinetic (cogwheel rigidity and tremors at rest) features are displayed by Parkinsonism. [3]
Four motor symptoms are considered cardinal signs in PD: slowness of movement (bradykinesia), tremor, rigidity, and postural instability. [1] Typical for PD is an initial asymmetric distribution of these symptoms, where in the course of the disease, a gradual progression to bilateral symptoms develops, although some asymmetry usually persists.
Often the symptoms of tardive dyskinesia are not apparent until the individual comes off of the antipsychotic drugs; however, when tardive dyskinesia worsens, the signs become visible. [24] Other dopamine antagonists and antiemetics can cause tardive dyskinesia, such as metoclopramide and promethazine, used to treat gastrointestinal disorders.
Essentially, by blocking this protein’s function, they could stop dyskinesia symptoms from developing in the mouse models, effectively erasing the brain’s memory of the motor response to L-DOPA.
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.
