The aim of the present study was to report the levels of ascorbic acid in amyotrophic lateral sclerosis (ALS) and Alzheimer's disease (AD) and the effectiveness of ascorbic acid homeostasis in the central nervous system. Plasma and CSF ascorbic acid levels were measured by high performance liquid chromatography in 19 ALS patients, 17 AD patients and 15(More)
HYPOTHESIS AND BACKGROUND Experimental evidence suggests that steroids as well as various neurotransmitters are critically involved in the functioning of the vestibular system in health and disease. Yet there are no pertinent human data. We hypothesized that changes in the serum levels of cortisol and plasma levels of excitatory and inhibitory(More)
Defective glutamate (Glu) metabolism and glutamate excitotoxicity have been implicated in the pathogenesis of amyotrophic lateral sclerosis (ALS). Glycine (Gly), the main inhibitory neurotransmitter, has been shown to potentiate excitatory transmission. In the present study, the levels of Glu and Gly in fasting plasma were measured by high performance(More)
