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 .
Effect of Modafinil on Learning and Task-Related Brain Activity in Methamphetamine-Dependent and Healthy Individuals
Methamphetamine (MA)-dependent individuals exhibit deficits in cognition and prefrontal cortical function . Therefore , medications that improve cognition in these subjects may improve the success of therapy for their addiction , especially when cognitive behavioral therapies are used . Modafinil has been shown to improve cognitive performance in neuropsychiatric patients and healthy volunteers . We therefore conducted a r and omized , double-blind , placebo-controlled , cross-over study , using functional magnetic resonance imaging , to examine the effects of modafinil on learning and neural activity related to cognitive function in abstinent , MA-dependent , and healthy control participants .  Modafinil ( 200 mg ) and placebo were administered orally ( one single dose each ) , in counterbalanced fashion , 2 h before each of two testing sessions . Under placebo conditions , MA-dependent participants showed worse learning performance than control participants . Modafinil boosted learning in MA-dependent participants , bringing them to the same performance level as control subjects ; the control group did not show changes in performance with modafinil . After controlling for performance differences , MA-dependent participants showed a greater effect of modafinil on brain activation in bilateral insula/ventrolateral prefrontal cortex and anterior cingulate cortices than control participants . The findings suggest that modafinil improves learning in MA-dependent participants , possibly by enhancing neural function in regions important for learning and cognitive control . These results suggest that modafinil may be a suitable pharmacological adjunct for enhancing the efficiency of cognitive-based therapies for MA dependence
