Raised Intracranial Pressure
Convulsions are attributed to raised intracranial pressure and elevated glutamate levels
RAISED INTRACRANIAL PRESSURE (↑ ICP)
- Focal mass lesions — tumours, abscesses, haemorrhages
- ↑ ICP → CSF displaced → pressure builds further
- Compresses vasculature → ↓ cerebral perfusion → ischaemic injury → more oedema (vicious cycle)

What our notes say
- Convulsions are attributed to raised intracranial pressure and elevated glutamate levels (Paediatrics end of second semester exam (MBPE 4300): 4 October 2022, cardiology,)
- The contraindications are signs of raised intracranial pressure or brain shift (abnormal posture, unequal or sluggish pupils, irregular breathing). (Paediatrics Year 6 MBChB end of semester CAT: clinical case MCQs, 29 of 30 quest)
- Haemorrhagic stroke: control blood pressure, reverse anticoagulation, treat raised intracranial pressure, and refer for neurosurgery if indicated. (Internal Medicine (MBIM 4100) main exam, Paper One: 3 July 2019)
- (b) Brain injury stimulates the respiratory centre directly (and through raised intracranial pressure, hypoxia and pain). (Chemical Pathology Semester 1 — Short Answer Questions)
