Long-term cognitive outcomes after pediatric stroke

Area of Science:

• Pediatric Neurology
• Neuropsychology
• Developmental Neuroscience

Background:

• Pediatric stroke is a significant cause of acquired brain injury in children.
• Understanding the long-term neurocognitive and neurologic sequelae is essential for effective management.
• Previous research highlights the impact of stroke on child development, but comprehensive assessments are needed.

Purpose of the Study:

• To assess and compare neurocognitive and neurologic outcomes in children with neonatal and childhood strokes.
• To identify specific areas of neurocognitive impairment and their correlation with stroke type and location.
• To emphasize the importance of early detection and intervention for pediatric stroke survivors.

Main Methods:

• Utilized the Estonian Pediatric Stroke Database (1995-2006) to identify participants.
• Included 21 children with neonatal strokes (mean age 6.86 years) and 10 with childhood strokes (mean age 8.21 years).
• Employed a developmental neuropsychologic assessment and the Paediatric Stroke Outcome Measure for outcome evaluation.

Main Results:

• Neuromotor impairment was observed in 62% of neonatal and 70% of childhood stroke cases.
• Children with strokes demonstrated poorer attention, language, memory, and sensorimotor functions compared to controls.
• Executive functions remained intact, potentially explaining normal intelligence, but neonatal strokes led to more severe visuospatial deficits.

Conclusions:

• Pediatric stroke survivors exhibit significant neurocognitive deficits, with sensorimotor and visuospatial domains being particularly affected.
• Neonatal strokes result in more severe neurocognitive impairments than childhood strokes.
• Epilepsy and left-hemisphere strokes are associated with poorer prognoses, underscoring the need for specialized neuropsychologic assessment and ongoing care.
