Presentation
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]
Polymicrogyria was present inside 23 clefts (43%), while subependymal heterotopias were present at the cleft orifice in 27 clefts (50%). [link.springer.com]
She presented at birth with growth retardation and microcephaly, and on the 3rd day of life she developed seizures. [cags.org.ae]
Polymicrogyria presents on MRI as very small fused gyri. Porencephalies are generally thought to arise from a destructive process. [medlink.com]
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]
Entire Body System
- Feeding Difficulties
She presented with severe psychomotor retardation, inability to speak, severe feeding difficulties, contractures of the large joints, and left-sided spasticity. She was found to have no metabolic or infectious disorders, and had a normal karyotype. [cags.org.ae]
Behavior and performance: Feeding difficulty. Heredity: The syndrome is familial and is transmitted as an autosomal recessive trait. [bridges4kids.org]
Psychiatrical
- Suggestibility
She had four healthy siblings, and no mutations were identified in the EMX2 gene, suggesting a sporadic neonatal schizencephaly. [cags.org.ae]
Several familial cases have been described and autosomal dominant inheritance linked to chromosome 13q has been suggested. COL4A1 is an essential component in basal membrane stability. [jmg.bmjjournals.com]

However, some observations of fami-lial recurrences have been reported, suggesting thatgenetic factors could be involved [Berg et al., 1983;Airaksinen, 1984; Smit et al., 1984; Zonana et al.,1986; Sensi et al., 1990; Robinson, 1991; Hilburgeret al., 1993 [docslide.com.br]

Neurologic
- Focal Seizure
Clinical findings include focal seizures in most patients (about 80% of cases in one large review), usually beginning before age 3 years in bilateral cases. [neuroscienceandgenetics.it]
We observed that 50% of the patients had epileptic seizures, which were mainly focal. In general, patients responded well to antiepileptic drugs. [elsevier.es]
- Cranial Nerve Involvement
Signs and symptoms were as follows: developmental delay and motor problems (unilateral or bilateral) in almost all patients, with differing degrees of severity; cranial nerve involvement, especially cranial nerve VI (bilateral in several cases), and focal [elsevier.es]
- Delayed Speech and Language Development
Possible symptoms include: delayed development and growth lack of muscle tone (also known as hypotonia) seizures a smaller or larger head circumference than average delayed speech and language development paralysis (usually on one side of the body) stiff [medic8.com]
- Spastic Quadriplegia
The primary diagnoses of the clients were listed as Cerebral palsy, Multiple sclerosis, Rhett syndrome, Developmental delay, Spinal muscular atrophy, Mitochondrial respiratory disorder, Tay-Sachs disease, Pelizaeus-Merzbacher disease, Spastic quadriplegia [medical-dictionary.thefreedictionary.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]
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]
There may be cortical atrophy and gliosis around the cyst margin. There may be ex vacuo dilation of the ipsilateral ventricle. [epilepsydiagnosis.org]
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]
Treatment
In general, treatment for individuals with schizencephaly usually consists of physical therapy, occupational therapy, treatment for seizures and, in a few cases complicated by hydrocephalus, a shunt is required. [thescipub.com]
Treatment Treatment generally consists of physical therapy and drugs to prevent seizures. [brainfacts.org]
If epileptic symptoms are present, treatment for seizures is given. [allhealthsite.com]
Treatment [ edit ] Treatment for individuals with schizencephaly generally consists of physical therapy (KG-ZNS with Vojta Methode), occupational therapy (with specific emphasis on neuro-developmental therapy techniques), treatment for seizures, [4] and [en.wikipedia.org]
Prognosis
Prognosis The prognosis for individuals with schizencephaly varies depending on the size of the clefts and the extent of neurological disabilities. [brainfacts.org]
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 [ edit ] The prognosis for individuals with schizencephaly varies depending on the size of the clefts and the degree of neurological deficit. [4] Frequency and inheritance [ edit ] In some cases, the defect is linked to mutations of the EMX2 [en.wikipedia.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]
Etiology perinatal cerebral ischemia trauma infection antenatal intraparenchymal hemorrhage 4 familial porencephaly: mutations in the COL4A1 gene (a COL4A1-related disorder ) leading to fragile blood vessels causing antenatal/perinatal hemorrhagic strokes [radiopaedia.org]
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]

Indeed, epidemiologic findings indicate that exogenous causes interfering with pregnancy have to be considered in addition to genetic defects. [medlink.com]
