The investigators hypothesize that the Q-collar compression on bilateral internal jugular veins of patients with low pressure hydrocephalus will decrease venous drainage from the intracranial space, therefore increasing intracranial volume, decreasing brain compliance, and increasing CSF drainage through the shunt. This should improve persistent hydrocephalus symptoms and demonstrate improved ventricular drainage on imaging with decompressed ventricles.
