The optimal cut-off value of 5.6 mm on the affected side corresponded with a sensitivity of 91.7% and a specificity of 100% for confirmation of SWS1 diagnosis. In SWS1 patients CP thickness and CP thickness ratio on non-contrast brain MRI was significantly increased. We studied specificity and sensitivity for SWS diagnosis of LMC and indirect MRI signs such as choroid plexus (CP) size and thickness, abnormal white matter signal, lobar cerebral atrophy, ischemia and cortical calcifications. In this retrospective single centre study, we included 24 SWS1 patients and 20 controls. Identification of sensitive and specific MRI predictors for early SWS1 diagnosis. Identification of pre-symptomatic SWS1 patients is hampered because brain MRI in the first months of life does not always show the for SWS1 characteristic leptomeningeal capillary malformation (LMC). Especially early onset seizures are associated with worse neurocognitive outcome. Clinical manifestations are severe and often progressive.

Up to 35 % of neonates with a high risk PWB develop SWS1. Patients with Sturge-Weber syndrome type 1 (SWS1) have a port-wine birthmark (PWB) as cutaneous hallmark. Advances in DNA sequencing and the development of new tools to correct human gene mutations have brought genetic analysis and gene therapy into the focus of investigations for new therapeutic options for stroke patients. The recent steps forward in our understanding of the disorders underlying strokes has given us a next generation of therapeutics and therapeutic targets by which to improve stroke survival, protect or rebuild neuronal connections in the brain, and enhance neural function. Single polymorphism frequencies may not be sufficient to completely explain the stroke causality and an analysis of several genotype combinations is a more promising approach.

The most frequently studied genetic risk factors are several common polymorphisms in genes associated with thrombophilia these genes code for proteins that are part of the coagulation cascade, fibrolysis, homocystein metabolism, lipid metabolism, or platelets. Besides monogenic disorders that may present with stroke as a first symptom, genetic polymorphisms may contribute to the risk of pediatric and perinatal stroke. In this review, the most significant single gene disorders associated with pediatric stroke are presented, along with specific therapeutic options whenever they exist. The recent development of molecular genetic methods has greatly facilitated the analysis and diagnosis of single-gene disorders. The early recognition of a stroke and stroke risk in children has the potential to advance the application of neuroprotective, thrombolytic, and antithrombotic interventions and rehabilitation strategies to the earliest possible timepoints after the onset of a stroke, improving the outcomes and quality of life for affected children and their families. The multifactorial etiopathology that has an influence on stroke development and occurrence signify the importance of the timely recognition of both modifiable and non-modifiable factors for adequate diagnostic and treatment approaches. Strokes within pediatric populations are considered to be the 10th leading cause of death in the United States of America, with over half of such events occurring in children younger than one year of life.
