Schizencephaly - Influence, Manifestation And Remedy

Schizencephaly, popularly called split brain, is an absurd situation in which brain breaks into grooves

. General building of brain in the first 210 days prior to pregnancy takes a wrong route; culminating in it. Precise precondition of the disease is unknown however.

Two Forms:

Splits can occur on any or two sides of brain and spread from its periphery to ventricles that carry fluid. There are two sorts of the malaise:

Open Lipped: The walls of the cleft are separated

Closed Lipped: No separation of cleft walls

The fissure in schizencephaly (an evolutionary disturbance), may simulate the boils that occur in porencephaly (problem due to superficial embryonic brain damage). They can be differentiated through MRI examination and the exact nature of brain tissue can be diagnosed.

In Schizencephaly disease, split is layered with brain tissue. Meanwhile scar tissue and white matter are evident in porencephaly.

Causes:

Reasons of the disease are unknown. Embryonic brain damage through the period of 4-6 months pregnancy is believed to be a cause. Damage may occur because of:

- Infection

- Reduced blood flow resulting in cerebrovascular accident (CVA, stroke)

- EMX2 gene mutation

Whereas splits may be layered with gray matter, they can also be enveloped by thick oversized tissue with voluminous bags, termed polymicrogyria. There may be Heterotopias (offensive neural clumps) as well situated in different portions of the brain. Polymicrogyra and heterotopias are thought to be the upshot of oversized nerve movement during parturition.

What are the manifestations?

Symptoms for this condition are dependent upon the the size of the clefts. Symptoms may include:

- Delay in development Small heads (microencephaly)

- Accumulation of fluid on the brain (hydeocephalus)

- Limb paralysis Hypotonia (reduced muscle tone)

- Spasticity (increased muscle tone)

- Mental retardation Seizures

How is it diagnosed?

Examination of genes is not presently possible. The disease comes to light only post MRI or CT scan of the brain.

Treatment:

Presently, there is no cure, but the goal of treatment is to manage the symptoms. Treatment may include:

- Anticonvulsants

- Surgical shunt in the brain to drain the fluid

- Surgical removal of the offending brain tissue that surrounds the cleft

The grave extent of split brain may be ascertained by the number of fissures and damage to the brain. Some sufferers may undergo fits and no other manifestations. Thanks to the unknown stature of the malaise, serious patients need total external assistance till death.
