Pure autonomic failure is defined as an idiopathic sporadic disorder characterized by orthostatic hypotension, usually with evidence of more widespread autonomic failure and no other neurologic features. It remains a diagnosis of exclusion. Specific attention should be directed toward some of the clinical features that were found to predict future development of multiple system atrophy or dementia with Lewy bodies in cases that are initially diagnosed with pure autonomic failure.

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.

Optic neuritis (ON) can occur alone or in many cases as a symptom of an underlying CNS autoimmune or demyelinating process like multiple sclerosis. It can also be associated with other causes like infection, granulomatous disease, and paraneoplastic and metabolic disorders. Optic nerve inflammation causes subacute loss of vision, usually in 1 eye, and usually associated with retro-orbital pain that is worsened with eye movement. Clinical recovery and prognosis will vary depending on the etiology.
