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 Improves Cognition and Attentional Set Shifting in Patients with Chronic Schizophrenia
Modafinil , a novel cognitive enhancer , selectively improves neuropsychological task performance in healthy volunteers and adult patients with attention deficit hyperactivity disorder ( ADHD ) . It has been argued that persistent cognitive deficits in patients with schizophrenia are responsible for the failure of many patients to rehabilitate socially even when psychotic symptoms are in remission . The present study examined the potential of modafinil as a cognitive enhancer in schizophrenia . Twenty chronic patients with a diagnosis of schizophrenia were entered into a double-blind , r and omized , placebo-controlled crossover study using a 200 mg dose of modafinil . Modafinil had some cognitive enhancing properties in schizophrenia similar to those observed in healthy adults and adult patients with ADHD . Improvement was seen on short-term verbal memory span , with trends towards improved visual memory and spatial planning . This was accompanied by slowed response latency on the spatial planning task . No effect on stop-signal performance was seen . Importantly , significant improvement in attentional set shifting was seen , despite no effect of modafinil on this task being seen in healthy volunteers or ADHD patients . Modafinil may have potential as an important therapy for cognitive impairment in patients with schizophrenia , particularly because of its beneficial effects on attentional set shifting
