Congenital or perinatal stroke may occur due to a cerebral injury that can manifest as early as 20-28 weeks gestation. This condition may cause seizures and an altered mental status that results in chronic developmental and neurologic disabilities. There are many reasons why congenital or perinatal strokes occur – the most common of which are asphyxiation at birth, blood or cardiac disorders, dehydration, infection, and maternal disorders (the mother's pre-existing conditions). While it can be difficult to pinpoint a specific treatment for congenital or perinatal stroke, an MRI of the brain is typically done to accurately diagnose the severity of the condition. If seizures and epilepsy become a concern, then an EEG may be performed. Depending on the type of stroke, testing for blood clotting issues and other disorders may also be ordered. Since recurrent seizures may occur in children who have experienced perinatal stroke, anticonvulsive medication is often part of the treatment. In the event that drugs do not correct the problems, multiple surgical procedures may be considered.
