“…It is, therefore, unlikely that the high proportion of generalized convulsions in the ES group is due to unwitnessed focal seizures. Janz (1962) and Gibberd and Bateson (1974) also found in patients with sleep epilepsy that generalized convulsions predominated over focal, absence, atypical absence and myoclonic seizures. It is difficult to determine, however, how often apparently generalized convulsions in sleep have a focal onset.…”

“…Figure I gives a graphic display of the previous and present studies of sleep epilepsy. ( Only the studies of Kajtor (1962), Gibberd andBateson (1974), D'Allesandro (1983) and our study identify the ES group while others combine ES and PS groups.) The relative occurrence of sleep epilepsy in these series varies from 7.5% to 45%.…”

“…Several authors (Gowers, 1901;Gibberd and Bateson, 1974;Janz, 1974;D'Allesandro, 1983) reported that 11 to 30% of patients whose seizures initially occur only in sleep may ultimately develop seizures during wakefulness. Since this usually occurs within six years (Gibberd and Bateson, 1974), we established a subgroup within the ES group with seizures only in sleep for at least six years.…”

“…To obtain a comparable group of patients with attacks mainly in wakefulness (W group) we selected 71 patients in alphabetical order, from the remainder. Because patients with seizures only in sleep infrequently develop seizures in wakefulness after six years (Gibberd and Bateson, 1974) we established a subgroup of ES patients with seizure disorders of greater than six years (ES>6 subgroup).Seizures were grouped according to the International Classification of Epileptic Seizures (1981) when possible. Because of the difficulty in determining whether generalized convulsive seizures occurring in sleep were primary or secondarily generalized, they were classified as "generalized convulsions"…”

ABSTRACT:A review of patients with epilepsy showed that 5.9% had seizures exclusively in sleep (ES) and 4.7% had seizures predominantly but not exclusively in sleep (PS). These groups were compared with a group (W) with seizures mainly in wakefulness. The following significant differences were obtained: 1) generalized convulsions predominated in the ES while partial seizures were more common among PS and W patients, 2) seizures occurred less frequently in the ES group, and 3) more W patients had EEGs with generalized epileptiform activity and positive family histories for epilepsy.We suggest the lower frequency of seizures in the ES group and the declining prevalence of sleep epilepsy are due to: 1) the high proportion of generalized as opposed to partial seizures in sleep and 2) more effective control of generalized seizures compared to partial seizures by modern anti-epileptic drug management. RESUME: Aspects differentiels de I'epilepsie du sommeil Une revision de nos patients epileptiques a montrd que 5.9% font des crises uniquement lors du sommeil (ES) et qu'un autre 4.7% font des crises de fa?on predominante, mais non exclusive, lors du sommeil (PS). Ces patients furent compares a un groupe (W) chez qui les crises ne sont qu'a l'eveil. Nous observons les differences significatives suivantes: (1) les convulsions generalisees predominent ches les ES alors que les crises partielles sont plus frequentes chez les sujets PS et W; (2) les convulsions sont moins frequentes dans le groupe ES; (3) plus de patients W avaient des EEG avec une activite epileptiforme generalised et une histoire familiale d'6pilepsie positive.Nous suggerons que la frequence plus basse des crises dans le groupe ES et la prevalence a la baisse d'6pilepsie du sommeil sont dues: 1) a la proportion plus elev£e de crises generalisees que partielles lors du sommeil et 2) au meilleur controle des crises gdneralisees par les traitements anti-epileptiques modernes.Can. J. Neurol. Sci. 1985: 12:317-320 "Sleep epilepsy" and "nocturnal epilepsy" are terms applied to seizure disorders in which the attacks occur only or predominantly during sleep. Most authors have considered sleep epilepsy as a single entity, contrasting it to seizures occurring on awakening or occurring randomly in the wake-sleep cycle.We examined two groups of patients with sleep epilepsythose with seizures occurring only during sleep and a group with seizures predominantly but not exclusively during sleep -to determine how they differed from each other and from a group with seizures mainly in wakefulness. METHODSWe searched our files of patients who were followed in epilepsy clinics at the University Hospitals in London, Ontario and Saskatoon, Saskatchewan for those with seizures exclusively in sleep (ES group) and for those with attacks predominantly but not exclusively in sleep (PS group). To obtain a comparable group of patients with attacks mainly in wakefulness (W group) we selected 71 patients in alphabetical order, from the remainder. Because patients with seizures only in...

Dangerous driving by drivers with diseases or disabilities such as dementia, epilepsy, or higher brain dysfunction is viewed as a problem In Worldwide. Given that the majority of such cases of dangerous driving are caused by impairments to cognitive function resulting from these conditions, there is an urgent need to create systems to detect drivers with cognitive functional disability and develop criteria for safe resumption of driving. Because driving would understandably be extremely dangerous for people with higher brain dysfunction, particularly in cases of attention dysfunction, we first examined the correlation between the Clinical Assessment of Attention (CAT), a theoretical task offering an index of attention function, and the cathode ray tube (CRT) driving aptitude test. We then examined correlations between CRT total score and CRT sub-scores. Only the time required for the position Stroop test had a moderate correlation (r = -0.43, p < 0.01) with CRT total score. Correlations between CRT total score and sub-scores relating to reaction speed showed a strong correlation. Other than reaction speed, items with significant moderate to strong correlations were also seen in the maintenance of moderate mental tension, attention distribution and situation processing skill.The present results show a correlation between CAT score and CRT total score, indicating that CRT total score places relative weights on speed of information processing and suppression of stereotypes, representing a very meaningful result.
