Insulin produces seizures in healthy and diabetic animals. Amongst suggested mechanisms, the role of neuromodulators and neurotransmitters is not clear. The present study explores the mechanisms involved in insulin-induced convulsions. Convulsions were induced in Swiss male albino mice with graded
The purpose of the study was to investigate the relation between the catecholamines: noradrenaline and dopamine in the rat brain on one hand and hypoglycemic convulsions and coma on the other. Concentrations of noradrenaline in the hypothalamus, brain stem and cerebral cortex were decreased during
The influence of hyperglycemia and moderate hypoglycemia plus electroconvulsive seizure on the permeability of the blood-brain barrier to protein was studied in rats. Evans blue was used as a blood-brain barrier tracer. Following a single electroconvulsive seizure, slight staining of brain tissue
OBJECTIVE
(1) To determine the characteristics of seizures and/or epilepsy among patients with adult onset type 1 diabetes mellitus (T1DM), and (2) to determine glutamic acid decarboxylase antibody (antiGADab) titres and other autoimmune characteristics of T1DM patients with seizure and/or
In order to determine the effects of acetate on signs and symptoms of hypoglycemic seizures, Swiss Webster albino mice were injected intraperitoneally with solutions of NaCl, NaHCO3, NH4Cl, Na-acetate, or NH4-acetate, followed by subcutaneous injection of 7 U of insulin/kg body wt. Administration of
A case of hypopituitarism in a female, aged 6 months, whose first symptom consisted of hypoglycemic convulsions is reported. Making use of TRH we confirm the hypothalamic origin of pituitary failure. Substitution therapy controlled the episodes of convulsions and normalized the growth rate of the
Based on the effects of gold thioglucose (GTG), we have previously proposed a regulatory center in brain which adjusts the convulsive response to insulin hypoglycemia. The sensitivity to insulin hypoglycemic convulsions is decreased 24 hr and increased 1 week after a single i.p. injection of GTG.
Six diabetic patients are described who sustained serious musculoskeletal injuries during insulin-induced hypoglycemia. The convulsions were associated with nocturnal hypoglycemia, superoptimal glycemic control, pregnancy, hypoglycemic unawareness, or errors in self-management.
Hyperekplexia is a rare, nonepileptic, genetic, or sporadic neurologic disorder characterized by startle responses to acoustic, optic, or tactile stimuli. Genetic defects in glycine receptors as well as encephalitis, tumors, inflammation, and disgenesis are among the etiologic causes of the disease.
A 12-year-old, 195 kg Shetland pony broodmare had eight seizures between May 29 and August 7, 1979. Plasma glucose levels during three of these seizures were markedly depressed (16, 18 and 19 mg/100 ml). Serum insulin levels were elevated during two of the seizures (86.0 and 97.7 microU/ml).
The brain is heavily dependant on glucose for its function and survival. Hypoglycemia can have severe, irreversible consequences, including seizures, coma and death. However, the in vivo content of brain glycogen, the storage form of glucose, is meager and is a function of both neuronal activity and
BACKGROUND
The neuropathology of hypoglycemia and its mechanisms have been well studied. However, the physiopathogenesis of hypoglycemia-related seizures has escaped elucidation. Various animal models reportedly show "seizures" when rendered hypoglycemic, however, correlation with the
The long-term follow-up of chronic hyperinsulinemic seizures, epileptogenesis and other neurological complications in five patients who were treated with conservative therapy followed by pancreatectomy during the neonatal period and infancy, who were confirmed to have diffuse nesidioblastosis are
We report a 74-year-old white woman with type 1 diabetes and major depressive disorder refractory to multiple medications who received 15 electroconvulsive therapy treatments with minimal improvement. After an accidental hypoglycemic seizure, the patient's symptoms completely resolved. In
Introduction Primary adrenal insufficiency is a potentially life-threatening condition that can have many underlying causes. Mutations in the steroidogenic acute regulatory protein (StAR) gene produce lipoid congenital adrenal hyperplasia (LCAH) which usually presents in the infantile period with
