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]
Here, we present a rare case of left, unilateral, open lip schizencephaly in an adult patient presenting with partial seizures but with an asymptomatic childhood. [jfmpc.com]

Other Pathologies
- Gliosis
On the other hand, lesions arising later are associated with gliosis, macrophage reaction, and calcification. [neuropathology-web.org]
Gliosis will develop if the insult is late enough, usually thought to be after the start of the third trimester, although perhaps insults as early as 20 weeks of gestation may result in gliosis 11. [radiopaedia.org]
There may be cortical atrophy and gliosis around the cyst margin. There may be ex vacuo dilation of the ipsilateral ventricle. [epilepsydiagnosis.org]
More mature brains have a greater capacity to develop a glial scar (gliosis) around the cyst. 13 After approximately 30 weeks’ gestation, there is a greater chance of reactive glial scarring. 14 Hydranencephaly represents an extreme form of bilateral [radiologykey.com]
The cyst is lined by white matter, which may or may not demonstrate evidence of gliosis (this depends on the age at which the insult occurred). [medigoo.com]
- White Matter Lesions
We observed porencephaly and white matter lesions in members from two families that lack COL4A1 mutations. [ncbi.nlm.nih.gov]

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]
Make the best clinical decisions with an enhanced emphasis on evidence-based practice and expert opinions on treatment strategies. Zero in on the most relevant and useful references with the aid of a more focused, concise bibliography. [books.google.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]
