The predisposing factors consist mainly of the individually inherited seizure threshold
(personal history of febrile convulsions or a family history of seizures) and other comorbid seizurogenic conditions, such as a history of head trauma, brain injury, intellectual disability, cerebral arteriosclerosis, neurodegenerative diseases, encephalopathy, chronic renal insufficiency, and hyponatremia.
(15) One of the important parameters in predicting clinical response is the degree to which the electrical stimulus exceeds the seizure threshold
. (16) The maintenance of adequate seizure duration on patients is a complicated issue.
The immediate early gene (IEG) expression is related to the seizure history, seizure threshold
and development of EL mouse (Murashima et al.
Whatever the reason, a person's seizure threshold
will play a key role.
He was treated with fight unilateral electrode placement, and seizure threshold
was determined by dose titration.
A low epileptic seizure threshold
may be inherited.
This is no longer recommended because neuroleptics impair heat dissipation and may lower the seizure threshold
. Neuroleptics may be useful if psychosis persists after the acute toxicity has resolved.
Once the seizure threshold
has been determined, the ECT machine is set using the mCi (millicuries) calibration at low (50% over threshold), moderate (150% over threshold), or high (400-500% over threshold).
Home Secretary Charles Clarke is to consult on whether the cash seizure threshold
under the Proceeds of Crime Act should be lowered from pounds 5,000 to pounds 1,000.
In 1964, Forster and his co-workers (Forster, Ptacek, Peterson, Chun & Bengzon, 1964) publish a study showing that it is possible to alter the seizure threshold
through the process of habituation.
Animal studies have shown that a drop in serum levels of the endogenous neurosteroid allopregnanolone, a progesterone metabolite, lower the seizure threshold
. But attempts to quell catamenial epilepsy via progesterone therapy have generally been thwarted by the finding that effective doses also result in depressive symptoms and other side effects, Dr.
Lindane is contraindicated in patients who are using drugs that lower the seizure threshold
such as antipsychotic drugs, benzodiazepines, systemic steroids, quinolone antibiotics, and antimalarials.
