The domain-specific attentional benefits of modafinil have yet to be quantified objectively in healthy human volunteers using tasks validated for comparison across species. These experiments were designed to test for domain-specific enhancement of attention and cognitive control by modafinil and mg in healthy volunteers using the 5-choice continuous performance task 5CCPT and Wisconsin Card Sort Task WCST. An additional cross-species assessment of arousal and hyperactivity was performed in this group and in mice 3.

A series of drugs have been reported to increase memory performance modulating the dopaminergic system and herein modafinil was tested for its working memory WM enhancing properties. Cognitive enhancement CE is one of the major concerns as cognitive impairment is a hallmark of aging and several brain disorders. Several drugs are available for the treatment of cognitive impairment and modafinil 2-[ diphenylmethyl sulfinyl] acetamide is one recommended and prescribed recently for CE Farah et al. Eagle et al. Cognitive enhancement effects of modafinil have been studied extensively in human volunteers: modafinil improved performance in short-term memory, WM, and inhibition control in sleeping disorders Scoriels et al. In attention deficit hyperactivity disorder, modafinil exhibited positive effects on short- and long-term memory Turner et al. Studies using modafinil on memory deficits in schizophrenic patients are quite promising and improvement of short-term verbal memory, verbal WM performance, spatial WM errors WMEs and strategy use is furthermore observed in schizophrenics Turner et al. Minzenberg et al. Moreover, modafinil was studied in healthy volunteers and significantly enhanced performance in trials of cognition such as WM, cognitive flexibility, and planning Muller et al. As to probable mechanisms of actions, modafinil binds to the dopamine transporter DAT increasing synaptic dopamine levels exciting dopaminergic and adrenergic receptors resulting in wakefulness Wisor,

In up-all-night, work-work-work America, a prescription medication like modafinil was sure to make major inroads from the get-go. Theodore A. Modafinil is also widely seen as a cognitive enhancement drug that helps patients do what must be done, without the jitters, sleeplessness and addiction potential of stimulant medications widely prescribed for attention deficit and hyperactivity disorder. On the Bulletproof Executive blog, self-described Silicon Valley entrepreneur and computer security expert Dave Asprey discusses his use of modafinil to boost alertness after marathon sessions of work and travel. While Asprey touts the benefits of healthy diet and exercise too, he nevertheless defends modafinil as a cognitive enhancement agent not unlike coffee. In , the FDA approved modafinil for the first time, for narcolepsy patients, and in , expanded the uses for which it could be marketed to patients with daytime sleepiness resulting from obstructive sleep apnea or shift-work sleep disorder. Physicians are expected to use their judgment and scientific knowledge gleaned from people other than drug-company representatives to recommend certain drugs to their patients who do not fit the FDA profiles.

Modafinil is a non-amphetamine central nervous system CNS stimulant with wakefulness-promoting properties. It is used in the treatment of conditions that cause excessive daytime sleepiness. Modafinil is known to be a weak inhibitor of dopamine reuptake, which may be its primary clinically important property. It has little to no in vivo affinity for the serotonin 5HT or norepinephrine NE transporters. However, elevated concentrations of NE and 5HT in the prefrontal cortex and hypothalamus have been observed following modafinil administration, possibly as an indirect effect of increased extracellular dopamine. Modafinil exists as a racemic mixture of S- and R-enantiomers. Additionally, modafinil has been postulated to increase signaling in the hypothalamic orexin and histamine neurotransmitter pathways, [13] and animal studies have also suggested a glutamatergic effect. This has been attributed to differences in its interaction with the dopamine transporter at the molecular level.

The novel wake-promoting agent modafinil has been in use for the treatment of several sleep disorders for a few years and is now undergoing clinical trials for its use in the treatment of stimulant addiction, but its primary mechanism of action remains elusive. Previous laboratory studies have shown that modafinil has antioxidative and neuroprotective effects, which have not previously been suggested to be related to its wake-promoting effects. In a unique drug for the treatment of narcolepsy was approved by the Food and Drug Administration for the narcolepsy armamentarium. Despite several years of pre-clinical research, the mechanism of action of modafinil was unknown.

Table 1 A description of behavior, calculations, and interpretation used to quantify effects in the 5C-CPT. Modafinil reduces extreme sleepiness due to narcolepsy and other sleep disorders, such as periods of stopped breathing during sleep obstructive sleep apnea. Even though modafinil is reported to reduce GABA-activated currents and extracellular GABA levels in different brain regions, the drug exerts antiepileptic effects Chen et al. Differential contributions of dopaminergic D1- and D2-like receptors to cognitive function in rhesus monkeys. Pronunciation moe-DAF-i-nil. Modafinil induces hyperactivity in mice at high doses.

Mice were tested in eight BPM chambers; each chamber consisting of a During the training session, the same arms were baited for each rat once at the beginning of each session to assess WM, while the other four arms were always left un-baited in order to test reference memory.

In attention deficit hyperactivity disorder, modafinil exhibited positive effects on short- and long-term memory Turner et al. Res 33 , 69— Membranes with bound radioligand were collected after dilution with buffer, with Brandel harvester on glass fiber filters GF-B or GF-C pre-soaked in 0. More From the Los Angeles Times. A multimethod approach to assessing perseverations in schizophrenia patients. Before entering the BPM room, patients were fitted with an ambulatory monitoring device Vivometrics, Ventura, CA worn around the torso to quantify motor activity. No significant main effects or interactions with gender were evident for any of these variables. Total brain concentrations of classical AEDs were quantified using a fluorescence polarization immunoassay technique. We also determined the effects of modafinil on the arousal and exploratory behavior of male and female mice at doses that are directly comparable to those used in human testing. Though it helps many people, this medication may sometimes cause addiction. Epilepsy Res. Plasticity of glutamate synaptic mechanisms.
