How does meningitis cause increased intracranial pressure?

Increased ICP in patients with bacterial meningitis seems to be multifactorial in origin. Cytotoxic and interstitial edema due to increased permeability of the blood-brain barrier is the main factor leading to increased ICP, although increased intracranial blood volume and disturbances in CSF flow may be important [2].

Does meningitis cause hypertension?

transient hypertension is known to occur in diseases associated with raised intracranial pressure,’ the association with acute meningitis is not documented. There was no clear evidence in our patient for raised intracranial pressure.

What are the signs and symptoms of bacterial meningitis?

Symptoms

  • Sudden high fever.
  • Stiff neck.
  • Severe headache that seems different from normal.
  • Headache with nausea or vomiting.
  • Confusion or difficulty concentrating.
  • Seizures.
  • Sleepiness or difficulty waking.
  • Sensitivity to light.

Does meningitis raised intracranial pressure?

Elevated ICP is a major and common complication of meningitis irrespective of the offending pathogen. For instance, when defining intracranial hypertension as ICP ≥ 15 mm Hg, Rebaud et al. observed that 86% of the patients with acute viral meningoencephalitis suffered intracranial hypertension.

What are signs of intracranial pressure?

What are the symptoms of ICP?

  • Headache.
  • Blurred vision.
  • Feeling less alert than usual.
  • Vomiting.
  • Changes in your behavior.
  • Weakness or problems with moving or talking.
  • Lack of energy or sleepiness.

What is meningeal intracranial hypertension?

Intracranial hypertension is a spectrum of neurological disorders where cerebrospinal fluid (CSF) pressure within the skull is elevated. Normal CSF pressure varies by age. In general, CSF pressure above 250 mm H20 in adults and above 200 mm H2O in children signifies increased intracranial pressure (ICP).

How does meningitis affect intracranial pressure?

Meningitis causes an imbalance between the water content of the brain parenchyma, CSF volume, and cerebral blood flow (CBF), resulting in an increase of ICP.

How is aseptic meningitis contracted?

For viral aseptic meningitis, risk factors include those for the specific agents. Enteroviruses can be transmitted by exposure to an infected individual’s secretions entering the oral cavity through sneezing or oral fecal contact.
