Intracranial Hypotension With Mild Parkinsonism And Bulbar Dysfunction

Spontaneous intracranial hypotension (SIH) is a well-studied entity that presents most classically with a postural headache.(1) However, many other symptoms have been characterized and can occur as a presenting complaint or as part of a broader syndrome, including alterations in arousal, memory, and bulbar function, and motor symptoms including bradykinesia and ataxia.(2) Kinetic and postural tremor has been reported as a presenting symptom of SIH,(3) but the frequency has not been well described, and this phenomenology rarely has been shown in video format. When appropriately identified, SIH represents a potentially reversible etiology for these symptoms.
