Neurophysiologic tests screening cognitive impairment in idiopathic intracranial hypertension patients.

ABSTRACT:

Background

Idiopathic intracranial hypertension (IIH) is a disorder with increased intracranial pressure of obscure cause. Patients with IIH may suffer from difficulty in thinking or concentrating. This work aimed at highlighting the neurophysiologic suggestions of cognitive impairment in IIH patients.

Methods

Twenty patients with IIH-and a similar number of matched control subjects-were examined in this case-control study. The P300 and contingent negative variation (CNV) were performed. Results from both groups were compared.

Results

There were significant lower means of P300 amplitude and CNV amplitude (early and late response) in patients than in controls. Also, there were significant delayed latencies of P300 and CNV in patients than in normal control subjects. Fi
