A community survey of dementia was conducted on a Chinese islet. A total of 221 men and 234 women in the age range of 50-92 were assessed. The Cognitive Abilities Screening Instrument (CASI), a 100-point cognitive test designed for cross-cultural studies and adapted in Chinese for individuals with little or no formal education, was administered twice by(More)
Lamotrigine (LAG) is an antiepileptic drug which is believed to suppress seizures by inhibiting the release of excitatory neurotransmitters. The present study was aimed at investigating the effect of LAG on the 4-aminopyridine (4AP)-evoked glutamate release in cerebrocortical nerve terminals (synaptosomes). LAG inhibited the release of glutamate evoked by(More)
BACKGROUND Most published studies have shown lower prevalence rates of Parkinson's disease (PD) in Asian and black African than in Western countries, leading to the hypothesis that Asians and blacks might be protected from PD. OBJECTIVE To investigate the prevalence of PD in a Chinese population. DESIGN Community-based survey. SETTING Registered(More)
To test the psychometric properties of the Chinese (Taiwanese) version of the short form 36 health survey (SF-36), 1,439 women, aged 40-54 years and living in Kinmen (a Taiwanese island reflecting a predominantly rural community) were recruited to participate in this survey. The rate of unavailable data points for the 36 tested items remained consistently(More)
Dysphagia is a frequent and potentially serious complication of Parkinson's disease (PD). We examined the oropharyngeal swallowing ability in 19 PD patients (15 men and 4 women, mean age 68.42 years, mean Hoehn and Yahr stage 1.8) using modified barium swallow before and after administering oral levodopa (in combination with benserazide). Twelve (63.2%)(More)
BACKGROUND Two recent surveys of depression among Chinese elderly people sampled different populations, used different case ascertainment methods and resulted in a seven-fold difference in prevalence rates. The present study was conducted to compare prevalence rates obtained with two commonly used methods in the same population, and to examine the risk(More)
In view of the fact that both kindling and fear-potentiated startle are expressed by long-term enhancement of synaptic transmission in the amygdala, synaptic plasticity in this area of the brain is of particular importance. Here, we show for the first time that low-frequency stimulation of the lateral nucleus at 1 Hz for 15 min elicited a long-term(More)
The Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE) provides ratings of an individual's changes in everyday cognitive functions during the previous 10 years. Original studies conducted in Australia showed that its score was not influenced by the subjects' educational backgrounds and that it performed at least as well as the Mini-Mental(More)
The actions of serotonin on rat basolateral amygdala neurons were studied with conventional intracellular recording techniques and fura-2 fluorimetric recordings. Bath application of 5-hydroxytryptamine (5-HT or serotonin) reversibly suppressed the excitatory postsynaptic potential in a concentration-dependent manner without affecting the resting membrane(More)
