Intervention Details:
    Dietary Supplement: Phosphatidylserine-Omega3 (SharpPS™-Gold)
    Treatment will consist of capsules containing 100 mg phosphatidylserine-Omega3. Dosage: 1 capsule X 3 times daily, with meals. Duration: 15 weeks

Primary Outcome Measures :
  1. Change From Baseline in Neuropsychological Computerized Test [ Time Frame: baseline, 15 weeks ]
    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).

Secondary Outcome Measures :
  1. Clinical Global Impression of Change (CGI-C)Scale [ Time Frame: 15 weeks ]
    The Clinical Global Impression of Change (CGI-C)scale is designed to record the clinician's global impression of change. Global improvement score ranges from 1 = "Very much improved", through 4 = "No change", to 7 = "Very much worse". Participants who experienced an improvement (scores 1, 2 or 3) were classified as improved over the treatment period.
