Can heterotopia cause seizures?

Periventricular heterotopia is a condition in which the nerve cells (neurons) do not migrate properly during early development of the fetal brain. People with this condition typically develop recurrent seizures ( epilepsy ) beginning in mid-adolescence.

What causes subependymal heterotopia?

As with other grey matter heterotopias, subependymal heterotopia is thought to result from interruption of normal neuronal migration.

What causes periventricular heterotopia?

In most cases, periventricular heterotopia is caused by mutations in the FLNA gene. This gene provides instructions for producing the protein filamin A, which helps build the network of protein filaments (cytoskeleton ) that gives structure to cells and allows them to change shape and move.

Can grey matter cause seizures?

Additionally, seizures may start on one side (unilateral) and can spread to involve both sides of the brain (bilateral) and become a generalized seizure. Bilateral periventricular nodular heterotopia (lining lateral ventricles) is the most common form of grey matter heterotopia.

Can heterotopia be cured?

Although there is no cure for X-linked periventricular heterotopia, there may be ways to manage the signs and symptoms in each individual. Seizures are typically treated with antiepileptic medications.

What is an example of heterotopia?

Some examples of heterotopia are cemeteries, movies, gardens and carpets, boarding schools, bordellos, toilets, pornographic spaces, holiday camps, mental institutions and saunas. Foucault also demonstrates how carpets were initially like gardens which could move across space.)

How common is GREY matter heterotopia?

GMH may constitute about 15% of cortical developmental malformations and may be found in about 2% of patients with epilepsy. In a study of 16 patients who were being evaluated for intractable epilepsy, all of them were found to have GMH – both laminar and nodular forms were discovered.

Does Gray Matter Heterotopia cause seizures?

Clinical context Developmental, cognitive and motor impairments can occur, and are more severe in those with bilateral or extensive heterotopia or other brain abnormalities. Seizures are common, seen in 80-90% of cases. There is a female predominance in cases of bilateral periventricular nodular heterotopia.

Is heterotopia a genetic disorder?

X-linked periventricular heterotopia or FLNA-related periventricular nodular heterotopia is a genetic disorder in which nerve cells in the brain do not migrate properly during early fetal development (a neuronal migration disorder). It is characterized by the presence of clumps of neurons near the brain’s ventricles.

What is heterotopia according to Foucault?

Heterotopia is a concept elaborated by philosopher Michel Foucault to describe certain cultural, institutional and discursive spaces that are somehow ‘other’: disturbing, intense, incompatible, contradictory or transforming. Heterotopias are worlds within worlds, mirroring and yet upsetting what is outside.

Are Heterotopias bad?

At the other extreme, heterotopia can result in severe seizure disorder, loss of motor skills, and mental retardation. Fatalities are practically unknown, other than the death of unborn male fetuses with a specific genetic defect.

Is gray matter Heterotopia a disability?

GMH is a neuronal migration disorder which is more common than was once thought in the time before MRI scans were regularly used. The condition most frequently presents with epilepsy but intellectual disability of varying severity is also commonly found.
