Outcome Measures

Primary Outcomes (1)

  • Improvement of Cognitive Performance (Change From Baseline in Neuropsychological Computerized Test)

    The computerized neuropsychological assessment software consists of seven separate tasks: symbol spotting, pattern identification, pattern recall, digit-symbol substitution, digits span forward, digits span backward and delayed pattern recall. Based on the results obtained in the single tasks, eight cognitive composite scores are calculated including focused attention, sustained attention, memory recognition \& recall, visuospatial learning, spatial short term memory, executive functions and mental flexibility.The total score range is from 0 to 100 points(0 is worse, 100 is best).

    Base line and 12 weeks

Interventions

CognitexDIETARY_SUPPLEMENT

Treatment will consist of one capsule of Cognitex (Life Extension, USA), three times a day, with meals, delivering a total of 600 mg GPC, 100 mg PS-omega 3, 20 mg vinpocetine, 50 mg uridine-5'-monophosphate (disodium), 550 mg plant extracts (150 mg wild blueberry, 125 mg ashwagandha, 150 mg grape seed, 125 mg hops, ginger and rosemary).
