Insights
Posterior reversible encephalopathy syndrome (PRES) is a neurological condition characterized by hypertension and brain imaging abnormalities. Prompt management, including blood pressure control and anti-epileptic drugs, often leads to recovery in children.
Area of Science:
- Neurology
- Pediatrics
- Radiology
Background:
- Posterior reversible encephalopathy syndrome (PRES) is a neurological disorder.
- It is characterized by severe hypertension and specific brain imaging findings.
- PRES may result from impaired cerebral autoregulation in response to acute blood pressure changes.
Purpose of the Study:
- To review the current understanding of Posterior Reversible Encephalopathy Syndrome (PRES) in children.
- To discuss predisposing factors, clinical presentation, and management strategies for pediatric PRES.
- To highlight the importance of early diagnosis and intervention in improving outcomes.
Main Methods:
- Literature review of pediatric cases with PRES.
- Analysis of predisposing factors, clinical manifestations, and imaging findings.
- Evaluation of treatment outcomes and prognostic indicators.
Main Results:
- Common predisposing factors in children include renal disease, autoimmune disorders, malignancy, transplantation, hypertension, sepsis, and certain medications.
- Management involves controlling hypertension, removing causative agents, and administering anti-epileptic medications.
- Most children achieve complete recovery, though recurrence is possible and persistent imaging abnormalities may indicate a poorer prognosis.
Conclusions:
- Early recognition and management of PRES in children are crucial.
- Addressing underlying causes and providing supportive care can lead to favorable outcomes.
- Further research is needed to fully elucidate the incidence and long-term prognosis of PRES in pediatric populations.
Purpose Of Review:
Posterior reversible encephalopathy syndrome, or PRES, is a constellation of severe, acute hypertension and specific brain imaging findings. This may be caused by failure of the cerebral autoregulatory system to manage acute or severe changes in blood pressure. The incidence in children is unknown but estimated to be more common in children with predisposing factors including renal disease, autoimmune disease, malignancy, solid organ transplantation, stem cell transplantation, hypertension, sepsis, and exposure to certain medications.
Recent Findings:
Management of PRES includes addressing hypertension, removing offending agents when possible, and anti-epileptic medications. Most children with PRES recover completely, but recurrence is possible. Lack of resolution of imaging findings likely portends a worse prognosis.
