Mutations in QARS, encoding glutaminyl-tRNA synthetase, cause progressive microcephaly, cerebral-cerebellar atrophy, and intractable seizures Zhang et al. (2014) The American Journal of Human Genetics;94(4):547-558.

AIM To study the difference between pyridoxine (PN) and its active form, pyridoxal phosphate, (PLP) in control of idiopathic intractable epilepsy in children. METHODS Among 574 children with active epilepsy, 94 (aged 8 months to 15 years) were diagnosed with idiopathic intractable epilepsy for more than six months. All received intravenous PLP 10 mg/kg, then 10 mg/kg/day in four divided doses...

Intractable epilepsy is commonly believed to be the main cause of uncontrolled seizures and hospitalization in epileptic patients. We study frequency and types of potential provocative factors in epileptic patients admitted with seizures, and suggest methods to decrease seizure occurrence and hospitalization. Over 6 months we prospectively studied all epileptic patients hospitalized for seizure...

Isolated sulfite oxidase deficiency is a very rare autosomal recessive disorder associated with metabolism of sulfur containing amino acids. A 4-month-old girl with intractable seizures and feeding difficulty diagnosed as isolated sulfite oxidase deficiency is presented.

A patient with medically intractable seizures and mesial temporal sclerosis underwent a left anterior temporal lobectomy and amygdalohippocampectomy. After 4 months, his seizures recurred and a left temporal, subdural grid of electrodes was placed to localise his seizure focus. Stimulation through the grid evoked four distinct "memories", or experiential phenomena, despite absence of the ipsila...

We report a case of Congenital peri-sylvian syndrome with intractable seizures, hypotonia and feeding problems since birth. MRI brain helped in making an early diagnosis and counselling parents.

This is a review of the use of neuroimaging in epilepsy outlining the imaging strategy for new onset seizures and also those with intractable focal seizures being investigated as potential epilepsy surgery candidates. The review describes the radiological features of conditions which may be encountered in each clinical context, together with advice on the optimum imaging protocols to detect epi...

Hypoglycaemia can lead to acute disorders of cognition, consciousness, epilepsy, transient ischemia, psychosis and chronic disorders of dementia and neuropathy. Misdiagnosis and delay in treatment are common and prolonged hypoglycemia can lead to permanent neurological deficit or fatal coma. Hypoglycemia caused by an insulinoma is a readily treatable condition that should be considered in the d...

In epilepsy, novel pharmacological and nonpharmacological treatment approaches are commonly assessed in model systems of acute motor and often generalized seizures. We developed a rodent model with short-term electrical stimulation of the perforant path resulting in stereotyped limbic seizures. Limbic structures play a major role in human intractable epilepsy. In 10 rats, single electrical 5-se...

We report a case of a 5-year-old boy with intractable partial seizures who developed a transient hemiparesis, worsening of the electroencephalogram (EEG) and a change in his seizure pattern with increased seizure frequency after receiving topiramate (TPM). Symptoms resolved within a month after TPM was discontinued. Clinicians need to be aware that TPM use may occasionally be associated with fo...
