Definitions
Reduction of CEREBROSPINAL FLUID pressure characterized clinically by ORTHOSTATIC HEADACHE and occasionally by an ABDUCENS NERVE PALSY; HEARING LOSS; NAUSEA; neck stiffness, and other symptoms. This condition may be spontaneous or secondary to CEREBROSPINAL FLUID LEAK; SPINAL PUNCTURE; NEUROSURGICAL PROCEDURES; DEHYDRATION; UREMIA; trauma (see also CRANIOCEREBRAL TRAUMA); and other processes. Chronic hypotension may be associated with subdural hematomas (see HEMATOMA, SUBDURAL) or hygromas. (From Semin Neurol 1996 Mar;16(1):5-10; Adams et al., Principles of Neurology, 6th ed, pp637-8)
