Seizure threshold
Glutamatergic and GABAergic balance in the brain that affects seizure susceptibility
The term seizure threshold is used to describe the balance between excitatory (glutaminergic) and inhibitory (GABA-ergic) forces in the brain which affect how susceptible a person is to seizures. Those diagnosed with epilepsy or certain other neurological conditions are more vulnerable to seizures if the threshold is reduced, and should be compliant with their anticonvulsant drug regimen.
Medications that lower seizure threshold include the antidepressant and nicotinic antagonist bupropion, the atypical opioid analgesics tramadol and tapentadol, reserpine, theophylline, antibiotics (fluoroquinolones, imipenem, penicillins, cephalosporins, metronidazole, isoniazid) and volatile anesthetics. So can other factors, including:
sleep deprivation
illicit drug use, such as cocaine
withdrawal from drugs or certain stimuli
fever
exposure to flashing or flickering lights (photosensitive epilepsy) including neon lights, strobe lights, video games or even patterns like narrow stripes
lengthy periods of fasting, malnutrition, starvation, high stress, fear, fatigue and exhaustion
menstruation
uncontrolled diabetes, and
other endocrine and metabolic irregularities like electrolyte or hormonal imbalances (for example, metabolic alkalosis)
Cancer and certain disorders of the nervous, cardiovascular and gastrointestinal systems can also influence the severity and frequency of seizures.
The public source identifies “Seizure threshold” as glutamatergic and GABAergic balance in the brain that affects seizure susceptibility. This brief keeps that definition visible, then builds a research path around Seizure, threshold and Glutamatergic.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Seizure threshold”, the useful work is to connect “glutamatergic and GABAergic balance in the brain that affects seizure susceptibility” to the records capable of establishing context and consequence.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 29, 2022. The linked authority identifier is Q7447053. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
