A survey of public awareness and understanding of and attitudes toward epilepsy was made in Taipei City and Chin-San Village, Taiwan in 1992. In a population sample of 2,610 adults, 87% had read or heard about epilepsy, 70% knew someone who had epilepsy, 56% had seen someone having a seizure, 18% would object to having their children associated with persons with epilepsy, 72% would object to having their children marry a person with epilepsy, 31% believed that epileptic persons should not be employed in jobs as other persons are, 7% believed that epilepsy was a form of insanity, 34% did not know the cause of epilepsy, 13% did not know what an epileptic attack was like, and 18% did not know what to recommend if their friends or relatives had epilepsy. Youth, higher education, and upper levels of employment were correlated with answers that were more favorable concerning epilepsy in all survey questions except for the question regarding marriage, for which the reverse was noted. The attitudes toward epilepsy disclosed by this study were more favorable than those detected in a similar survey conducted in Henan Province, China. The comparison suggests that the exposure to Western culture and socioeconomic system in Taiwan might have helped reduce the discrimination against epilepsy.

The awareness, understanding, and attitudes toward epilepsy in 1,278 men and women were surveyed in Henan, China in 1988. Results showed that 93% had read or heard about epilepsy; 77% knew someone who had epilepsy; 72% had seen someone who was having a seizure; 57% would object to having their children associate with persons with epilepsy in school or at play; 87% would object to having their children marry a person with epilepsy; 53% believed that epileptic persons should not be employed in jobs as other persons are; 16% believed that epilepsy was a form of insanity; 40% did not know the cause of epilepsy; 10% did not know what an epileptic attack was like; and 17% did not know what to recommend if their friends or relatives had epilepsy. The relationship between the responses and the respondents' age, sex, marital status, number of offspring, level of education, occupation, and residence was analyzed. Education reduced the respondent's prejudice against play and employment, but did not change their objection to marriage and appeared to have reinforced their linking epilepsy with insanity. As compared with the surveys conducted in Western countries, our survey showed that awareness of epilepsy in China was greater, if not the same, but the attitudes toward epilepsy were much more negative.

To explore whether depth of sleep is related to changes in autonomic control, continuous power-spectral analysis of the electroencephalogram (EEG) and heart rate variability (HRV) was performed in ten normal subjects during nocturnal sleep. Quiet sleep (QS) was associated with an increase in high-frequency power (HF) of HRV (0.15-0.4 Hz) but a decrease in low-frequency power (LF) (0.04-0.15 Hz) to HF ratio (LF/HF) compared with awakening. During QS, LF/HF was significantly and negatively correlated with delta power of EEG (0.5-4.0 Hz), whereas mean R-R interval and HF were not. We conclude that during QS, cardiac sympathetic regulation is negatively related to the depth of sleep, although vagal regulation is not. Our methodology offers a quantitative analysis to study the interaction between cerebral cortical and autonomic functions.

Syncope with and without convulsion was studied in unselected blood donors in a community blood center. Convulsive syncope occurred in 0.03% of all blood donors and was more commonly observed when nursing personnel were alerted to its possible occurrence. It was more common in men. Although tonic extensor spasm was the most common convwithout convulsion was studied in unselected blood donors in a community blood center. Convulsive syncope occurred in 0.03% of all blood donors and was more commonly observed when nursing personnel were alerted to its possible occurrence. It was more common in men.

Convulsive syncope occurred in 0.03% of all blood donors and was more commonly observed when nursing personnel were alerted to its possible occurrence. It was more common in men. Although tonic extensor spasm was the most common convulsive movement, other complex convulsive phenomena occurred, some simulating epileptic seizure. No statistical difference in changes of pulse or blood pressure was found between subjects with convulsive versus nonconvulsive syncope. Similarly, no difference was found between subjects with tonic spasm and those with other convulsive phenomena, nor between those with "early" and those with "delayed" reactions. Marked individual variation may exist in the susceptibility of the central nervous system to ischemia. Some individuals appear to be predisposed to development of seizures in situations of global cerebral ischemia such as occur in hypotension and bradycardia.

Summary:Purpose: To assess the efficacy and safety of adjunctive levetiracetam (LEV) therapy in controlling partial-onset seizures refractory to other antiepileptic drugs (AEDs) in a multicenter study in Taiwanese adults.Methods: Ninety-four patients aged 16-60 years with refractory partial seizures were randomized to receive LEV (n = 47) or placebo (47) for 14 weeks and composed the intention-to-treat (ITT) population. After the first 2 weeks, LEV patients had their dosage increased from 500 mg twice daily to 1,000 mg twice daily. A 12-week maintenance phase followed, after which patients switched to long-term, open-label LEV therapy or entered a 4-week phase of medication discontinuation.Results: All patients from the ITT population, except one LEVtreated patient with missing seizure-count data, were included in the primary efficacy analysis. The least square mean of logarithmically transformed weekly partial-seizure frequency was significantly lower in the LEV than in the placebo group (0.813 vs. 1.085; p = 0.001). LEV reduced log-transformed weekly partial-seizure frequency by 23.8% (95% confidence interval, 10.4-35.2%) relative to placebo. Significantly more LEV than placebo patients (43.5% vs. 10.6%) experienced a response of a ≥50% decrease from baseline in weekly frequency of partial seizures [odds ratio, 6.5 (95% CI, 2.2-19.3); p < 0.001]. Adverse events were reported in 34 (72.3%) of 47 LEV-treated patients and 32 (68.1%) of 47 placebo patients. The three most common adverse events in the LEV and placebo groups were somnolence (40.4% and 14.9%), dizziness (14.9% and 8.5%), and headache (10.6% and 8.5%), respectively. Only four patients (three LEVtreated patients and one placebo patient) were withdrawn from the study because of adverse events.Conclusions: Adjunctive LEV therapy, ≤1,000 mg twice daily, was significantly more effective than placebo and was generally well tolerated in Taiwanese adults with treatmentresistant partial-onset seizures.
