If an ultrasound shows the possibility of clefts in the cerebral hemispheres at this point, doctors may order a magnetic resonance imaging (MRI) scan, which can more definitively identify the defect. The brain will not heal itself with time. The Hydrocephalus Clinical Research Network (HCRN) has been established by philanthropic funding to conduct multi-institutional research (clinical trials and observational studies) on pediatric hydrocephalus. At least three different kinds of therapists can help people with schizencephaly live more independently and improve their quality of life: Because so little is known about this schizencephaly, researchers are often looking for people who have the condition to participate in clinical trials. Potential long-term complications of Schizencephaly include: Avoidance of risk factors during pregnancy is the best way to decrease the risk of Schizencephaly: Parents with a family history of the disorder or who have had another child with familial Schizencephaly are advised to consult a genetic counselor to assess their risk if they plan to have another child. These problems can be mild, moderate, or severe. -, Klingensmith WC, 3rd, Cioffi-Ragan DT. Childs Nerv Syst. These clefts can appear on one or both sides of the brain. Babies with clefts in both hemispheres (bilateral clefts) commonly have: Individuals with clefts in only one hemisphere (unilateral clefts) are often paralyzed on one side of the body but may have average to near-average intelligence. Approximately 70 percent of cerebral clefts are found in the frontal lobes and parietal lobes of the brain, although if they are large they may extend into the occipital lobes and temporal lobes. The unilateral form of the condition is less severe than the bilateral type. In these cases, the condition seems to have been inherited.

Sometimes, schizencephaly can be completely asymptomatic. Careers. These are called bilateral clefts, and they often cause developmental delays and intellectual impairments. . In addition, it has been associated with mutations in several genes, including the EMX2, SIX3, SHH, and COL4A1 genes. Patients with unilateral schizencephaly often survive well into adulthood while those with the bilateral form are unlikely to survive past the age of 20. Walk and talk later than other children The underlying cause of schizencephaly is that the neurons of the brain fail to properly distribute themselves during early fetal development, leaving the characteristic cracks in the grey matter of the cortex. During fetal brain development, cells must move. Schizencephaly is considered a rare disease, which often means there is not much information known about it. 2015 Apr;31(4):551-6. https://doi.org/10.1007/s00381-015-2638-1.

JUMP TO Some scientists believe the COL4A1 mutations interfere with the normal production of type IV collagen, and, as a result, tissues are weaker than usual. Electroencephalogram (EEG): to evaluate seizures Seizure medication: Many children with schizencephaly will have seizures. Average age at the time of imaging of 14 patients (seven men; seven women) with SEH was 35 years (range 1750). Schizencephaly occurs very rarely. Our Information Specialists are available to you by phone or by filling out our contact form. The structural brain abnormalities are usually diagnosed by brain MRI or sometimes CT scans. Although many genetic abnormalities of the brain are rare and lethal, rapidly advancing knowledge of the structure of the human genome makes it a realistic goal to identify genes responsible for several other epileptic conditions. Fluid accumulation in the brain (hydrocephalus) that may cause neurological symptoms. 1988;150:13916. 2020 Feb 25;15(1):159-161. doi: 10.4103/ajns.AJNS_293_19. Common treatments and therapies include: In some cases, where seizure activity was localized near the cleft, and the seizures did not respond to medication, surgery to remove the cleft has effectively controlled the seizures. Surgery to place a thin tube (called a shunt) in the brain to drain fluid when hydrocephalus is a complication. CNF is not responsible for actions taken based on the information included on this webpage. Unfortunately, schizencephaly is so rare that it is often misdiagnosed early on, and it is only after an MRI is finally performed that the true condition is identified.
