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 a single dose of citalopram on amygdala response to emotional faces
Background Selective serotonin reuptake inhibitors ( SSRIs ) are typically thought to have a delay of several weeks in the onset of their clinical effects . However , recent reports suggest they may have a much earlier therapeutic onset . A reduction in amygdala responsivity has been implicated in the therapeutic action of SSRIs . Aims To investigate the effect of a single dose of an SSRI on the amygdala response to emotional faces . Method Twenty-six healthy volunteers were r and omised to receive a single oral dose of citalopram ( 20 mg ) or placebo . Effects on the processing of facial expressions were assessed 3 h later using functional magnetic resonance imaging . Results Volunteers treated with citalopram displayed a significantly reduced amygdala response to fearful facial expressions compared with placebo . Conclusions Such an immediate effect of an SSRI on amygdala responses to threat supports the idea that antidepressants have an earlier onset of therapeutically relevant effects than conventionally thought
