Epileptogenesis is the gradual process by which a typical brain develops epilepsy. [1] Epilepsy is a chronic condition in which seizures occur. [2] These changes to the brain occasionally cause neurons to fire in an abnormal, hypersynchronous manner, known as a seizure. [3]
After brain injuries, there is a limited window of time to intervene with treatments to prevent epilepsy, similar to the therapeutic approach used in stroke therapy. Epileptogenesis may occur rapidly, further narrowing this window, but a delayed process known as "secondary epileptogenesis" can influence the progression and severity of epilepsy ...
There are many causes of seizures. Organ failure, medication and medication withdrawal, cancer, imbalance of electrolytes, hypertensive encephalopathy , may be some of its potential causes. [ 2 ] The factors that lead to a seizure are often complex and it may not be possible to determine what causes a particular seizure, what causes it to ...
Systemic infection with high fever is a common cause of seizures, especially in children. [3] [25] These are called febrile seizures and occur in 2–5% of children between the ages of six months and five years. [26] [25] Acute infection of the brain, such as encephalitis or meningitis are also causes of seizures. [3]
A seizure is a paroxysmal episode of symptoms or altered behavior arising from abnormal excessive or synchronous brain neuronal activity. [5] A focal onset seizure arises from a biological neural network within one cerebral hemisphere, while a generalized onset seizure arises from within the cerebral hemispheres rapidly involving both hemispheres.
[2] [1] The involvement of the anterior insula in ecstatic seizures was first elucidated in 2009, and ecstatic experiences were first artificially induced by stimulation of this brain area in 2013. [2] [1] [4] [5] [6] Some leading historical religious figures, such as Saint Paul the Apostle and Joan of Arc, have been suspected as having ...
However, the most common mechanical models of traumatic brain injury such as fluid percussion injury, controlled cortical impact, and weight-drop injury models exhibit epileptogenesis at chronic time points with documented remote electroencephalographic and behavioral seizures, and increased seizure susceptibility. [43]
Epilepsy refers to a group of chronic neurological disorders that are characterized by seizures, affecting over 50 million people, or 0.4–1% of the global population. [3] [4] There is a basic understanding of the pathophysiology of epilepsy, especially of forms characterized by the onset of seizures from a specific area of the brain (partial-onset epilepsy).
