  2. Occipital neuralgia - Wikipedia

    Patients presenting with a headache originating at the posterior skull base should be evaluated for ON. This condition typically presents as a paroxysmal, lancinating or stabbing pain lasting from seconds to minutes, and therefore a continuous, aching pain likely indicates a different diagnosis. Bilateral symptoms are present in one-third of cases.

    VBI is often considered when a patient complains of dizziness. It is important to distinguish dizziness caused by vertigo from the sensation of being light-headed, as the latter is more commonly a result of other conditions. Brief episodes of vertigo brought on by head movements are more likely to be Benign paroxysmal positional vertigo.

    At the same time the cranium triples in volume from 500 cm 3 to 1500 cm 3 to accommodate the growing brain. [60] During human evolution, the skull underwent numerous changes to accommodate the growing brain. The evolutionary changes included increased size and shape of the skull, decreased basal angle and basicranial length.

  6. Idiopathic intracranial hypertension - Wikipedia

    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]

  7. Intracranial pressure - Wikipedia

    en.wikipedia.org/wiki/Intracranial_pressure

    Intracranial pressure (ICP) is the pressure exerted by fluids such as cerebrospinal fluid (CSF) inside the skull and on the brain tissue. ICP is measured in millimeters of mercury and at rest, is normally 7–15 mmHg for a supine adult. This equals to 9–20 cmH 2 O, which is a common scale used in lumbar punctures. [1]

    Heavy-headedness is the feeling of faintness, dizziness, or feeling of floating, wooziness. [1] [2] [3] Individuals may feel as though their head is heavy; also feel as though the room is moving/spinning also known as vertigo.

    The ICD-10 established a set of diagnostic criteria for PCS in 1992. [38] In order to meet these criteria, a patient has had a head injury "usually sufficiently severe to result in loss of consciousness" [33] [39] and then develop at least three of the eight symptoms marked with a check mark in the table at right under "ICD-10" within four weeks.
