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]

Hypovolemia

Intact cerebral blood flow (CBF) is essential for cerebral metabolism and function, whereas hypoperfusion in relation to hypovolemia and hypocapnia can lead to severe cerebral damage. This study was designed to assess internal carotid artery blood flow (ICA-BF) during simulated hypovolemia and noninvasive positive[…] [ncbi.nlm.nih.gov]

Dehydration

Abstract This hospital-record review describes the clinical profile of hypernatremic dehydration in neonates. 49 neonates (3.4% of the total admitted newborns) developed hypernatremic dehydration between January 2014 and August 2015. The major presenting complaints were fever (34.6%), poor feeding (42.8%), loose[…] [ncbi.nlm.nih.gov]

Cervical Spondylosis

Overview Cervical spondylosis is a general term for age-related wear and tear affecting the spinal disks in your neck. As the disks dehydrate and shrink, signs of osteoarthritis develop, including bony projections along the edges of bones (bone spurs). Cervical spondylosis is very common and worsens with age. More[…] [mayoclinic.org]

Syringomyelia

Syringomyelia is a generic term referring to a disorder in which a cyst or cavity forms within the spinal cord. This cyst, called a syrinx, can expand and elongate over time, destroying the spinal cord. The damage may result in loss of feeling, paralysis, weakness, and stiffness in the back, shoulders, and extremities.[…] [en.wikipedia.org]

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]

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]
