Low Intracranial Pressure: Causes & Reasons

Possible Causes for Low Intracranial Pressure

Hypovolemia and low mean arterial blood pressure are severe threats to cerebral perfusion in brain injury. [nursestudy.net]

After inflammation, hemorrhage, and trauma, the latter causes intracranial hypertension, causing circulation to be more pressure-dependent. Acute tubular necrosis. [nursestudy.net]

Spinal Epidural Hematoma

High pressure decreases the perfusion pressure in brain blood vessels (since the perfusion pressure is the mean arterial pressure minus the intracranial pressure). [dartmouth.edu]

If this is too low, there will be further damage to neural tissue due to ischemia, which will result in further edema and an even greater increase in pressure. [dartmouth.edu]

Dehydration

Abstract Exercise-induced dehydration can lead to impaired perfusion to multiple regional tissues and organs. We propose that the impact of dehydration on regional blood flow and metabolism is dependent on the extent of the cardiovascular demand imposed by exercise, with the greatest physiological strain seen when[…] [ncbi.nlm.nih.gov]

Syringomyelia

About Syringomyelia General Information Syringomyelia is a condition in which a cyst (pocket of fluid) forms within the spinal cord. This cyst, called a syrinx, can expand over time, damaging the center of the spinal cord. Since the spinal cord connects the brain to nerves in the arms and legs, this damage can result[…] [neurosurgery.ucla.edu]

Intracranial Hypotension

Low pressure headache without apparent provocation is termed spontaneous intracranial hypotension (SIH). [bmj.com]

Some authors postulate that the development of SDHs corrects the abnormally low intracranial pressure or volume [ 1 ]. [journals.plos.org]

Previously used terms: Headache attributed to spontaneous low CSF pressure or primary intracranial hypotension; low CSF-volume headache; hypoliquorrhoeic headache. [ichd-3.org]

Essential Intracranial Hypotension

Classic low-CSF-pressure headaches are severe, exacerbated by postural factors, and often mimic the ball valve effect seen in some intraventricular brain tumors. [aibolita.com]

Meningeal enhancement is usually thickest in patients with low intracranial pressure and subdural fluid collections are only seen in patients with meningeal enhancement. [brainscape.com]

Two main mechanisms tried to explain bleeding in the subdural space: First, tearing or rupture of bridging veins stretched by low intracranial pressure and the brain downward [omicsonline.org]
