Neurologic
- Seizure
Individuals whose seizures at the most recent visit were fully controlled (seizure-free) for 6 months or longer were more likely to have ever tried, or currently used, oxcarbazepine or carbamazepine than those with uncontrolled seizures. [ncbi.nlm.nih.gov]

[…] or a delayed systemic hypersensitivity reaction after intake of a drug that they had also taken during a previous anticonvulsant DRESS which had occurred months or years earlier; in the fifth, a possible reaction was prevented thanks to the allergy workup [ncbi.nlm.nih.gov]
Initial emergency interventions by the interprofessional team include: Obtaining a thorough history and drug history whenever possible Recognition of toxidromes when present Stabilization including hemodynamic and airway support Laboratory workup including [statpearls.com]
Refer patients with intractable spells to a neurologist or an epileptologist for further workup, including video-electroencephalographic (EEG) monitoring, to characterize the etiology of their seizures. [emedicine.medscape.com]
Treatment
[…] should be avoided if possible → teratogenic effects Newer anticonvulsants: lack of medical data and trials during pregnancy Choice of treatment depends on type of seizure and which substance enables optimal control of treatment. [amboss.com]
Severe neurological and psychomotor deterioration combined with increased seizure activity showed a lack of response to the treatment. At the age of 29 mon the patient was in a pre-comatose stage at which time melatonin was added to treatment. [ncbi.nlm.nih.gov]
Anticonvulsants are also being used in the treatment of neuropathic pain and as mood stabilizers in the treatment of psychiatric disorders such as bipolar disorder. [medlink.com]
Prognosis
As has been the trend with prognosis in sICH, scores have been developed to stratify sICH patients’ risk of seizures. [ahajournals.org]
Prognosis Patients often recover fully from anticonvulsant toxicity. Cardiac and neurologic complications may lead to permanent debilitating conditions if resuscitation is not available. This can cause significant morbidity and mortality. [ncbi.nlm.nih.gov]

There is some evidence that initiating anticonvulsants after a single seizure may not result in improvement in the long term prognosis and may not reduce the risk of injury or mortality.1,2 Selection of an anticonvulsant is generally guided by the type [bpac.org.nz]
Etiology
The most common etiologic factors were hypoglycemia (14.6%), hypoxic ischemic encephalopathy (12.2%), and hypocalcemia (12.2%). [go.gale.com]
Investigations ruled out an infectious etiology; an adverse event following phenobarbital administration was considered. [ncbi.nlm.nih.gov]
It is hoped that this will further our understanding of the initial stages of pregnancy and the etiology of various reproductive disorders. [news-medical.net]

Perhaps the greatest evidence that glutamate modulation might be important in the pathophysiology of mood disorders comes from the clinical use of the anticonvulsant lamotrigine. [dictionary.cambridge.org]
