Presentation
Presentation and outcome are variable ◦ Seizures ◦ Hemiparesis ◦ Developmental deficits Usually, the severity of symptoms is related to the amount of brain affected by the abnormality 5. [slideshare.net]
Increased tone known as spasticity or low-tone (hypontonia) may be present as well. While the above characteristics may be present in some patients, other patients may present with only seizures. [physio-pedia.com]
Patients with closed-lip schizencephaly typically present with hemiparesis and/or motor delay whereas patients with open-lip schizencephaly usually present with hydrocephalus and/or seizures. [pediatricneurosciences.com]
the patients also presented infantile spasms and tonic, clonic and tonic-clonic seizures. [elsevier.es]

- Developmental Delay
Signs and symptoms : Patients usually display signs and symptoms of global developmental delays, abnormalities and delays in speech and language skills, and seizures. [xpertdox.com]
Patients may show developmental delay that can range from mild to severe. Bilateral and open-lip clefts are associated with more severe delay. [checkorphan.org]
Developmental delays are common in these patients and the level of delay can range from mild to severe. If the clefts are either bilateral or open-lip, the delay will typically be more severe. [physio-pedia.com]
Some characteristics include developmental delays, seizures, and decreased muscle tone. Common symptoms reported by people with schizencephaly Reports may be affected by other conditions and/or medication side effects. [patientslikeme.com]

Treatment
If epileptic symptoms are present, treatment for seizures is given. [allhealthsite.com]
Treatment for Schizencephaly Individuals with schizencephaly may benefit from physical therapy and treatment to control seizures. Cases involving hydrocephalus may call for implantation of a shunt. [healthcommunities.com]

Treatment Treatment is addressed to alleviating symptoms, not to curing the underlying problem, as there is no treatment to induce the brain to grow missing sections of the cerebrum. [encyclopedia.com]
Treatment generally consists of physical therapy and drugs to prevent seizures. [diseaseinfosearch.org]
Prognosis
Prognosis for Infants with Hydranencephaly Prognosis is poor. Most infants die within their first year. Schizencephaly Schizencephaly is a form of porencephaly in which the brain's hemispheres are marked by abnormal slits or clefts. [healthcommunities.com]
Prognosis The prognosis for individuals with schizencephaly varies depending on the size of the clefts and the extent of neurological disabilities. [brainfacts.org]
Prognosis - Schizencephaly The prognosis for individuals with schizencephaly varies depending on the size of the clefts and the degree of neurological deficit. [checkorphan.org]
Etiology
The etiology of the disease is not well understood, but genetic and nongenetic etiologies have been postulated [ 5 ]. The role of genetics remains controversial, namely the gene EMX-2 [ 6 ] and COL4A1 mutations [ 7 ]. [karger.com]
Etiology/Causes As previously mentioned, the cause of schizencephaly is unknown. In fact, multiple causes have been proposed. [physio-pedia.com]
Its overall incidence is unknown, etiology must be multi-factorial and some series suggest that there is a risk that a patient with Porencephaly has at 2-4 per cent chance of having a child with a neural tube defect. [bridges4kids.org]
