Cognitive and mood improvements of caffeine in habitual consumers and habitual non-consumers of caffeine
TLDR
The present placebo-controlled, double-blind, balanced crossover study investigated the acute cognitive and mood effects of caffeine in habitual users and habitual non-users of caffeine and found that caffeine tended to benefit consumers’ mood more while improving performance more in the non-consumers. Expand
Chewing gum selectively improves aspects of memory in healthy volunteers
TLDR
The effects of chewing gum was examined using acomprehensive and sensitive cognitive assessment battery and two tasks manipulating cognitive load, and heart rateresponses were also measured. Expand
Consumption of cocoa flavanols results in acute improvements in mood and cognitive performance during sustained mental effort
TLDR
This is the first report of acute cognitive improvements following CF consumption in healthy adults, and the mechanisms underlying the effects are unknown they may be related to known effects of CF on endothelial function and blood flow. Expand
Glucose administration, heart rate and cognitive performance: effects of increasing mental effort
TLDR
It is suggested that supplemental glucose preferentially targets tasks with a relatively high cognitive load, which itself mobilises physiological reserves as part of a natural response to such tasks. Expand
Cognitive and physiological effects of an “energy drink”: an evaluation of the whole drink and of glucose, caffeine and herbal flavouring fractions
TLDR
There is some degree of synergy between the cognition-modulating effects of glucose and caffeine which merits further investigation, and the whole drink resulted in significantly improved performance on “secondary memory” and “speed of attention” factors. Expand
Cognitive demand and blood glucose
TLDR
It is suggested that the amount of cognitive load associated with task performance is an index of its sensitivity to enhancement by glucose, which may be linked to increased neural energy expenditure during a period of intense cognitive processing. Expand
The effects of l-theanine, caffeine and their combination on cognition and mood
TLDR
The results suggest that beverages containing L-theanine and caffeine may have a different pharmacological profile to those containing caffeine alone. Expand
Cognitive Performance, Hyperoxia, and Heart Rate Following Oxygen Administration in Healthy Young Adults
TLDR
The results confirm that oxygen administration significantly enhances cognitive performance above that seen in the air inhalation condition, and suggest that under periods of cognitive demand a number of physiological responses are brought into play that serve to increase the delivery of metabolic substrates to active neural tissue. Expand
Increased intensity of Ecstasy and polydrug usage in the more experienced recreational Ecstasy/MDMA users: a WWW study.
TLDR
The increased use of Ecstasy is associated with more intensive patterns of Ec ecstasy/MDMA intake, and the greater use of illicit CNS stimulants and hallucinogens, but not of alcohol, nicotine, or cannabis. Expand
Herbal medicine for depression, anxiety and insomnia: A review of psychopharmacology and clinical evidence
TLDR
A review of the literature was conducted to ascertain mechanisms of action of these botanicals, in addition to a systematic review of controlled clinical trials for treatment of mood, anxiety and sleep disorders, which are common comorbid psychiatric disorders. Expand
