The increased pressure causes a rupture of the cranial dura mater, leading to a CSF leak and intracranial hypotension. [46] [47] Patients with a nude nerve root, where the root sleeve is absent, are at increased risk for developing recurrent CSF leaks. [48] Lumbar disc herniation has been reported to cause CSF leaks in at least one case. [49]
One of the most damaging aspects of brain trauma and other conditions, directly correlated with poor outcome, is an elevated intracranial pressure. [10] ICP is very likely to cause severe harm if it rises too high. [11] Very high intracranial pressures are usually fatal if prolonged, but children can tolerate higher pressures for longer periods ...
One of the common causes of subdural hygroma is a sudden decrease in pressure as a result of placing a ventricular shunt. This can lead to leakage of CSF into the subdural space especially in cases with moderate to severe brain atrophy. In these cases, symptoms such as mild fever, headache, drowsiness and confusion can be seen, which can be ...
Occasionally, the CSF pressure measurement may be normal despite very suggestive symptoms. This may be attributable to the fact that CSF pressure may fluctuate over the course of the normal day. If the suspicion of problems remains high, it may be necessary to perform more long-term monitoring of the ICP by a pressure catheter. [8]
Normal pressure hydrocephalus (NPH), also called malresorptive hydrocephalus, is a form of communicating hydrocephalus in which excess cerebrospinal fluid (CSF) builds up in the ventricles, leading to normal or slightly elevated cerebrospinal fluid pressure. The fluid build-up causes the ventricles to enlarge and the pressure inside the head to ...
Camptocormia, also known as bent spine syndrome (BSS), is a symptom of a multitude of diseases that is most commonly seen in the elderly. It is identified by an abnormal thoracolumbar spinal flexion, which is a forward bending of the lower joints of the spine, occurring in a standing position.
The virus usually causes mild, cold-like symptoms, and most people recover in a week or two. In some cases, adults can be infected with the virus and not have symptoms. The virus is highly ...
It can cause headaches, made worse by standing, moving and coughing, [33] as the low CSF pressure causes the brain to "sag" downwards and put pressure on its lower structures. [33] If a leak is identified, a beta-2 transferrin test of the leaking fluid, when positive, is highly specific and sensitive for the detection for CSF leakage. [ 34 ]
