MATERIALS AND METHODS In a prospective study we evaluated patients with first generalized tonic-clonic seizure (GTCS) (n = 16, age: 31 +/- 11 years, 8 women) and patients with vaso-vagal syncope (VVS) (n = 17, age: 32 +/- 13 years, 8 women), diagnosed on the basis of past history and clinical presentation who had serum creatine kinase (CK) levels assessed(More)
There is meager information in the literature regarding the characteristics and risk factors for injuries caused during epileptic seizures in adults. Previous studies focused mainly on specific types of injuries incurred, and only few explored associated risk factors. A questionnaire regarding lifetime seizures and their traumatic consequences was(More)
Information on the effects of newer antiepileptic drug (AEDs) on the electroencephalogram (EEG) is sparse and contradictory. Quantitative EEG (qEEG) provides a method of estimating the effects of drugs on the central nervous system. Twenty-three adult patients with difficult-to-control complex partial seizures, with or without secondary generalization,(More)
Data are available on the yield of a single EEG recording in patients with epilepsy but there is little information on EEG findings as an aid in supporting the diagnosis of an epileptic event in patients presenting with a first-ever event suspected of being an unprovoked seizure. We retrieved files of patients above the age of 15 years admitted through the(More)
Epilepsy is a multifaceted chronic disorder which has diverse and complex effects on the well-being of the patient. Although it is evident that seizure type and frequency play a critical role in the quality of life (QOL) of patients with epilepsy, it is less clear what the major determinants are that influence QOL in seizure-free patients receiving(More)
Acute meningitis is associated with headache, but the natural history of the headache following recovery is unknown. We addressed this issue in 141 patients admitted during 1990 to 1993 with laboratory-confirmed meningitis. We excluded patients younger than 5 years (n=44), elderly demented patients (n=6), and those with potential causes of headache other(More)
Acetazolamide-responsive periodic ataxia (ARPA) is a rare movement disorder, characterized by recurrent episodes of vertigo, cerebellar ataxia, and nystagmus, which has recently been characterized genetically. The pathophysiology is unknown, but it is probably not epileptic. By definition, acetazolamide produces an impressive symptomatic relief. Because of(More)
IRDA (intermittent rhythmic delta activity) is an abnormal generalized EEG pattern that is not specific to any single etiology and can occur with diffuse or focal cerebral disturbances. To determine whether different electrographic features of IRDA and associated EEG findings can differentiate underlying focal from diffuse brain disturbances, we performed a(More)
To determine the incidence of traumatic events among epileptic patients compared with non-epileptic individuals, we distributed a questionnaire on physically traumatic events occurring during the preceding three months to consecutive epileptic patients and to age- and sex-matched controls. There were 145 epileptic patients, 121 with seizures (age 36 +/- 15(More)
It has not been established whether electroencephalography (EEG) is a contributing factor in predicting the outcome of surgery for epilepsy. We conducted a prospective study on 26 patients (M/F 14/12, age: 33 +/- 7.5 years, range 19-48) with mesial temporal lobe epilepsy (MTLE) who were followed for 2 years after surgery and who underwent routine EEG(More)
