Reversible posterior leukoencephalopathy syndrome (PRES/RPLS) requires prompt recognition and immediate action. The central objective is identifying and reversing whatever is driving the syndrome — before irreversible injury occurs.
Management is supportive. The first priority is identifying and removing or reversing the precipitating factor — this may include a causative medication such as a chemotherapy or immunosuppressive agent. Hydration and correction of electrolyte disturbances are also required as part of immediate management.
When acute hypertension is present, the protocol calls for a structured, gradual reduction in blood pressure using first-line intravenous antihypertensive agents delivered by continuous infusion. The approach is carefully titrated to avoid overshoot and end-organ ischaemia.
Controlled blood pressure reduction — by no more than 20–25% within the first few hours — targeting a mean arterial pressure within the safe therapeutic range, without precipitating cerebral, coronary, or renal ischaemia.
