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 ...
The postictal state is the altered state of consciousness after an epileptic seizure.It usually lasts between 5 and 30 minutes, but sometimes longer in the case of larger or more severe seizures, and is characterized by drowsiness, confusion, nausea, hypertension, headache or migraine, and other disorienting symptoms.
Other post-ictal neurological findings that do not involve activity of the area affected by the seizure have been described. They are thought to be caused by a different mechanism than Todd's paresis, and including paralysis of the contralateral limb, [5] and rare genetic causes of hemiplegia and seizures. [6]
It is a type of pain seizure that can remain isolated or be followed by other manifestations of the seizure. [3] On the other hand, a ictal non-epileptic headache is a headache that occurs during a seizure but it is not due to an epileptic mechanism. When the headache does not occur in the vicinity of a seizure, it is defined as inter-ictal ...
In an Israel-based study of infants born between 1995 and 2002, seizures occurred in 102 of 541, or 18.7%, of PVL patients. [9] Seizures are typically seen in more severe cases of PVL, affecting patients with greater amounts of lesions and those born at lower gestational ages and birth weights.
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.
[1] [3] [2] In children seizures may be seein in up to 90% of cases of PRES. [1] If seizures occur they may be focal or generalized. [3] [4] About 18% of people who have seizures develop status epilepticus, where seizures are not controllable with simple measures. [2]
The production of seizure-like symptoms is not under voluntary control; [10] [11] symptoms which are feigned or faked voluntarily would fall under the categories of factitious disorder or malingering. [12] Risk factors for PNES include having a history of head injury, and having a diagnosis of epilepsy. [13]
