A review of its effects in schizophrenia suggests that modafinil facilitates cognitive functions , with pro-mnemonic effects and problem solving improvements .
The systematic review on the neurochemical modulation of the modafinil suggests that its mnemonic enhancing properties might be the result of glutamatergic and dopaminergic increased neuronal activation in the hippocampus and in the prefrontal cortex respectively .
Other neurotransmitters were also activated by modafinil in various limbic brain areas , suggesting that the drug acts on these brain regions to influence emotional responses .
Modafinil is a central nervous system wake promoting agent used for the treatment of excessive daytime sleeping .
Its vigilance promoting properties and low abuse potential has intrigued the scientific community and has led to use it as a cognitive enhancer , before its neural functions were understood .
Here , we review the effects of modafinil in human cognition and emotion and its specific actions on symptoms in patients with schizophrenia and whether these are consistently effective throughout the literature .
We also performed a systematic review on the effects of modafinil on neurotransmitter signalling in different areas of the brain in order to better underst and the neuromechanisms of its cognitive and emotional enhancing properties .
Modafinil Attenuates Disruptions in Cognitive Performance During Simulated Night-Shift Work
Common complaints among shift workers are sleep disruptions and increased sleepiness while working , which may contribute to shift workers being more susceptible to diminished performance and work-related accidents . The purpose of this double-blind , within-participant study was to examine the effects of the alerting agent modafinil on cognitive/psychomotor performance , mood , and measures of sleep during simulated shift work . In all , 11 participants completed this 23-day residential laboratory study . They received a single oral modafinil dose ( 0 , 200 , 400 mg ) 1 h after waking for three consecutive days under two shift conditions : day shift and night shift . Shifts alternated three times during the study , and shift conditions were separated by an ‘ off ’ day . When participants received placebo , cognitive performance and subjective ratings of mood were disrupted during the night shift , relative to the day shift . Objective and subjective measures of sleep were also disrupted , but to a lesser extent . Modafinil reversed disruptions in cognitive performance and mood during the night shift . While modafinil produced few effects on sleep measures during the night shift , the largest dose produced several sleep alterations during the day shift . These data demonstrate that abrupt shift changes produced cognitive performance impairments and mood disruptions during night shift work . Therapeutic doses of modafinil attenuated night-shift-associated disruptions , but the larger dose produced some sleep impairments when administered during day-shift work
