Intracranial hypertension (IH), also known as intracranial pressure (ICP), refers to the pressure inside the skull and thus in the brain tissue and cerebrospinal fluid. Millimeters of mercury (mmHg) is used to measure intracranial hypertension which is normally 7–15 mm Hg. When it rises at 20–25 mm Hg, treatment will be needed to lower the intracranial pressure. Benign intracranial hypertension means the situation is not serious, and it develops in slow pace. But, benign intracranial hypertension needs medical treatments, too. Here are the possible causes of intracranial hypertension:
  • Increased venous pressure
  • Brain tumor
  • Generalized brain swelling
  • Obstruction to CSF flow and absorption
  • Craniosynostosis
