Paroxysmal dyskinesias are a relatively rare subset of hyperkinetic movement disorders that are defined by their episodic nature. They may be categorized into paroxysmal kinesigenic dyskinesia, paroxysmal nonkinesigenic dyskinesia, and paroxysmal exertion-induced dyskinesia. Paroxysmal dyskinesias may be sporadic, genetic, or caused by metabolic or structural etiologies. Another common cause of paroxysmal dyskinesias is psychogenic movement disorders.

Startle epilepsy is characterized by seizures precipitated by sudden, unexpected stimuli, usually sound or touch. Startle-induced seizures mainly consist of axial tonic posturing, frequently causing falls, which can often be traumatic. Typically it affects children with severe neurologic deficits, brain anoxia, infantile hemiparesis, and Down syndrome. The prognosis is often poor, particularly for those with severe preexisting encephalopathies

Wilson disease is caused by mutations in ATP7B that result in abnormal copper metabolism, and subsequent excess free copper is toxic. The main clinical categories of neurologic Wilson disease have been traditionally divided variably into tremor, dysarthria, pseudosclerosis (tremor +/- dysarthria), parkinsonism, dystonia, or chorea. The aim of treatment is to reduce the amount of toxic free copper.

Neuromyelitis optica spectrum disorder (NMOSD) is a destructive, inflammatory disease of the CNS historically characterized by selective involvement of the spinal cord and optic nerves. Manifestations of NMOSD include optic neuritis, transverse myelitis, and simultaneous optic nerve and spinal cord involvement. A prodrome of headache, low-grade fever, myalgia, fatigue, upper respiratory symptoms, or gastrointestinal symptoms can precede neurologic deficits.
