hyperthyroidism/癲癇性発作

A 16-year-old girl with a history of Graves' disease presented with two episodes of generalised tonic-clonic seizures, necessitating intensive care admission. Laboratory examination demonstrated a suppressed thyroid-stimulating hormone level with dramatically elevated free triiodothyronine, free

Although simple febrile seizures are relatively common and benign in toddlers, it is important to rule out any underlying critical disease that necessitates further intervention and treatment. Thyroid storm, the extreme manifestation of hyperthyroidism, is relatively rare and not often considered in

Thyroid hormones are essential for brain development, and maternal thyroid disease may affect child neurocognitive development. Some types of seizures may also depend upon early exposure of the developing central nervous system, and we hypothesized that maternal thyroid dysfunction could increase

Brain excitability has been inconsistently reported to be increased both in hypo- and hyperthyroidism, but there have been few studies on the effects of thyroid hormones on brain excitability in children. With this in mind, we investigated the incidence of febrile convulsions (FCs) among patients

Superior sagittal sinus thrombosis (SSST) is associated with a variety of hypercoaguable states. Although coagulation disturbances are reported in hyperthyroidism, a direct link between hyperthyroidism and cerebral venous thrombosis is not established. We report a 39-year-old man who developed

Graves' disease, which is an organ-specific autoimmune disorder, is the most frequent cause of thyrotoxicosis. Females are more often affected than males. The clinical pattern varies, however, and nearly every organ system may be involved. This case study describes a formerly healthy young woman

Epilepsy is the most common serious neurological condition and sudden unexpected death in epilepsy (SUDEP) is the most important direct epilepsy-related cause of death. Information concerning risk factors for SUDEP is conflicting, but high seizure frequency is a potential risk factor. Additionally,

Thyroid hormone deficiency is frequently associated with central nervous system (CNS) disturbances such as mental retardation, convulsions, coma etc. Studies of quantitative changes in CNS in hypo- or hyperthyroidism are scarce. Evoked potentials is a good method of assessing the electrical response

Cerebral venous sinus thrombosis (CVT) is an uncommon yet serious condition. While CVT has many known precipitants and etiologies, hyperthyroidism as a precipitant of CVT is not well understood. This study reported a case of a 41-year-old male with a 4-year history of hyperthyroidism presented with

A 48-year-old woman was admitted to our hospital because of headache and fever. She was diagnosed with aseptic meningitis. Five days later, she had a seizure and developed left hemiparesis. Magnetic resonance imaging showed hyperintensity in the right parietal area on fluid attenuated inversion

Superior sagittal sinus thrombosis (SSST) is an uncommon cause of stroke, whose symptoms and clinical course are highly variable. It is frequently associated with a variety of hypercoagulable states. Coagulation abnormalities are commonly seen in patients with hyperthyroidism. To the best of our

MELAS syndrome is a form of mitochondrial myopathy with manifestations of seizure, stroke-like syndrome, lactic acidosis, ragged red muscle fibres and mitochondrial encephalopathy. The syndrome has been reported in association with a variety of endocrine and metabolic disorders including diabetes

Thyroid hormone lowers the seizure threshold. We present the case of a female patient who developed generalized convulsions emerging with Graves' disease, and clarified the clinico-electroencephalographic characteristics. Before treatment, electroencephalography (EEG) showed 2- to 2.5-Hz diffuse

Seizures or encephalopathy associated with thyrotoxicosis are very rare. A 30-year-old man with thyrotoxicosis and strongly positive thyroid antibodies presented with generalised seizures preceded by an encephalopathic illness of a few days duration. CSF protein was raised and EEG showed bilateral

The stroke occurs in nearly 800,000 patients per year in the United States with significant morbidity if not treated and managed in a time sensitive manner. Acute bulbar weakness can be a common presenting manifestation of acute stroke and transient ischemic attack. However, up to 30% of the
