By “neuropsychologically healthy human' is meant However, because cognitive performance fundamentally lim a person who does not have and has not been diagnosed with its achievement throughout life, it would be desirable for a neurological, cognitive, psychiatric, or sleep disorder, e.g., neuropsychologically health persons to improve cognitive one listed herein; who is not suffering from sleep deprivation, performance. disrupted sleep-wake cycles, head trauma, cerebral vasocon striction sequelae, stroke, or otherischemic event in the brain; SUMMARY OF THE INVENTION who does not have age-related dementia or cognitive decline; 0005. In one aspect, the invention features a method of who is not using, abusing, withdrawing from, or dependent on improving cognitive performance by administering a cyti a controlled Substance, e.g., alcohol, stimulants including dine-containing or uridine-containing compound to a neurop amphetamines, methamphetamine, methylphenidate, and sychologically healthy human. cocaine, marihuana, and opiate or opioid drugs; and who is 0006. In preferred embodiments, the improved cognitive not using or dependent on tobacco or nicotine. performance is increased attention or attentional control, 0013 By “improving cognitive performance' is meant accuracy under time pressure, working memory, or learning increasing in speed, accuracy, or effectiveness the perfor aptitude; the compound administered is CDP-choline, uri mance of a cognitive function. By “cognitive function' is dine, or triacetyluridine; the cytidine-containing or uridine meant mental processes involving manipulation of informa containing compound is provided in a nutraceutical compo tion and sensory input. sition, e.g., a drink or tablet, optionally containing one or 0014. By “increased' is meant detectably higher in ability more of vitamin B6, vitamin B12, niacin, folic acid, tyrosine, or capacity, as may be perceived by the human or evidenced phenylalanine, taurine, malic acid, glucuronolactone, and by, e.g., a neuropsychological test. The increase may be, e.g., caffeine; and the cytidine-containing or uridine-containing a 2%. 5%, 10%, or 50% increase in cognitive performance of compound is administered orally. a human relative to the cognitive performance of the human 0007. In another embodiment, the cytidine-containing or prior to treatment with the cytidine-containing or uridine uridine-containing compound is administered chronically, containing compound. e.g., for a period of 3, 5, 10,90, or 180 days or 1, 5, or 10 years. 0015. By “attention' is meant the cognitive process of 0008. In certain embodiments, the method may involve selectively focusing on one aspect of the environment while diagnosing a human as neuropsychologically healthy prior to ignoring other aspects. administration of the cytidine-containing or uridine-contain ing compound. 0016. By “attentional control' is meant the appropriate 0009. In another aspect, the invention features a nutraceu direction of attention to the most relevant aspect of the envi tical composition comprising an effective amount of a cyti rOnment. dine-containing or uridine-containing compound and option 0017.
