The author reports his results of parenteral piracetam treatment in 193 patients admitted to the Psychiatric Department of Semmelweis Hospital with alcohol withdrawal delirium. Alcohol withdrawal delirium is a complex metabolic disorder, the disturbance of the highest cerebral integrative functions, which is caused by the impairment of cerebral oxidative metabolism. Piracetam is effective on most neurotransmitter systems, without a...
Abstract Glutamate alpha-amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid (AMPA) receptors mediate most of the excitatory neurotransmission in the mammalian central nervous system and also participate in forms of synaptic plasticity thought to underlie memory and learning, and the formation of neural networks during development. Molecular cloning techniques have shown that the AMPA receptor family is composed of four different subunits named GluR1-4 or...
Abstract This case study from Santa Cruz County Children's Mental Health Agency (CMH), California, reviews the use of measurement of heart rate variability (HRV) to enhance emotional regulation of patients. CMH serves seriously emotionally disturbed youths, many of whom have been separated from their parents for a prolonged period or have been vulnerable without the consistent presence of their...
Piracetam is a prototype of nootropic drugs used to improve cognitive impairment. However, recent studies suggest that piracetam can have analgesic and anti-inflammatory effects. Inflammatory pain is the result of a process that depends on neutrophil migration, cytokines and prostanoids release and oxidative stress. We analyze whether piracetam has anti-nociceptive effects and its mechanisms. Per oral pretreatment with piracetam...
Abstract Aniracetam, a cognition enhancer, has been recently found to preferentially increase extracellular levels of dopamine (DA) and serotonin (5-HT) in the prefrontal cortex (PFC), basolateral amygdala and dorsal hippocampus of the mesocorticolimbic system in stroke-prone spontaneously hypertensive rats. In the present study, we aimed to identify actually active substances among aniracetam and its major metabolites and to clarify...
Abstract The present study tests the activity of nootropic drugs in a behavioral test linked to depression. This test measures the reduction of submissive behavior in a competition test as the relative success of two food-restricted rats to gain access to a feeder. Nootropic drugs tested include piracetam (2-oxo-1-pyrrolidineacetamide), aniracetam (1-(4-methoxybenzoyl)-2-pyrrolidinone), the Ampakine, Ampalex, 1-(quinoxalin-6-ylcarbonyl)piperidine, and analogs were compared...
Abstract RATIONALE: Aniracetam has been reported to be efficacious for treating poststroke depression, but no studies that basically examined the antidepressive effects have been made. OBJECTIVE: We aimed to test the antidepressant-like property of aniracetam in rats and to clarify the mechanisms of action through the interaction studies with some receptor antagonists.
Abstract The anxiolytic effects of aniracetam have not been proven in animals despite its clinical usefulness for post-stroke anxiety. This study, therefore, aimed to characterize the anxiolytic effects of aniracetam in different anxiety models using mice and to examine the mode of action. In a social interaction test in which all classes (serotonergic, cholinergic and dopaminergic) of compounds were...
"These incorrect responses often matched the incorrect response of the majority group... Overall, in the experimental group, 75% of the participants gave an incorrect answer to at least one question while only 25% never gave an incorrect response." "interview data revealed that participants who did not conform to the majority group and thus, remained "...independent" from the group, reacted...
Biochemical markers of niacin status were studied in healthy young men fed 6.1 to 32 niacin equivalents (NE) per day over an 11-wk period while residing in a metabolic unit. Methylated metabolites of niacin, N1-methylnicotinamide (NMN) and N1-methyl-2-pyridone-5-carboxamide (2-pyr), in urine and plasma were determined during periods of low (6.1 or 10.1 NE per day), adequate (19 NE per...
