The lesions (i.e., scar tissue) caused by the loss of these neurons can result in groups of neurons forming a seizure "focus" area with episodic abnormal firing that can cause seizures if the focus is not abolished or suppressed via anticonvulsant drugs.
In its extreme form, reactive astrogliosis can lead to the appearance of newly proliferated astrocytes and scar formation in response to severe tissue damage or inflammation. Molecular triggers that lead to this scar formation include epidermal growth factor (EGF), fibroblast growth factor (FGF), endothelin 1 and adenosine triphosphate (ATP ...
Micrograph showing gliosis in the cerebellum. Reactive astrocytes on the left display severe proliferation and domain overlap. Reactive astrogliosis is the most common form of gliosis and involves the proliferation of astrocytes, a type of glial cell responsible for maintaining extracellular ion and neurotransmitter concentrations, modulating synapse function, and forming the blood–brain ...
If anticonvulsants fail to control seizure activity, neurosurgery may be an option to remove or disconnect the abnormal cells from the rest of the brain (depending on where the cortical dysplasia is located and the safety of the surgery relative to continued seizures). Neurosurgery can range from removing an entire hemisphere (hemispherectomy ...
In some cases, certain parasites can cause seizures. The Schistosoma sp. flukes cause Schistosomiasis. Pork tapeworm and beef tapeworm cause seizures when the parasite creates cysts at the brain. Echinococcosis, malaria, toxoplasmosis, African trypanosomiasis, and many other parasitic diseases can cause seizures.
A glial scar formation is a reactive cellular process involving astrogliosis that occurs after injury to the central nervous system.As with scarring in other organs and tissues, the glial scar is the body's mechanism to protect and begin the healing process in the nervous system.
Anything that causes epilepsy causes epileptogenesis, because epileptogenesis is the process of developing epilepsy. Structural causes of epilepsy include neurodegenerative diseases, traumatic brain injury, stroke, brain tumor, infections of the central nervous system, and status epilepticus (a prolonged seizure or a series of seizures ...
Magnetic resonance-guided laser interstitial thermal therapy, stereotactic radiosurgery, and stereotactic radiofrequency ablation are surgical methods that treat epilepsy by destroying the abnormal brain tissue that causes seizures. [35] [36] [37] Neurostimulation may also improve seizure control. [6]
