University of Arizona researchers have revealed new insights into the neurobiological cause of the involuntary, uncontrollable movement disorders that develop in patients with Parkinson’s disease (PD) ...

Motor issues—such as coordination problems, motor slowing or sudden, uncontrolled movements—have been recognized as signs of ...

Tardive dyskinesia, or TD, is a drug-induced movement disorder that can occur in individuals taking certain medications that block dopamine receptors in the brain. Most commonly, cases of TD are ...

People with uncontrolled movement problems can have a harder time doing everyday tasks such as speaking, reading, writing, and cooking, which can cause a loss of independence. This may cause people to ...

Most studies of cognitive control over eye movement have covered more obvious movements, such as the "saccade" movements in which the eyes dart across large parts of the visual field. In the new study ...

Just days after an upbeat R&D event, Neurocrine Biosciences has found itself having to report a phase 3 failure. The company’s Ingrezza (valbenazine), approved to treat certain uncontrolled movement ...

In a novel set of experiments with mice trained to do a sequence of movements and "change course" at the spur of the moment, Johns Hopkins scientists report they have identified areas of the animals' ...

Scientists have identified previously unknown neural modules in the brain that control movement and adapt during skill learning. Their findings challenge long-held ideas about how the brain organizes ...

Athetosis and chorea are two types of involuntary movements that can occur in children and adults with neurological conditions, such as cerebral palsy. The movements have different features, and the ...

Chorea-acanthocytosis is a rare genetic disorder of the nervous system. It causes involuntary jerks and twitches in the muscles, known as chorea, and star-shaped red blood cells, known as ...

A very subtle and seemingly random type of eye movement called ocular drift can be influenced by prior knowledge of the expected visual target, suggesting a surprising level of cognitive control over ...
