Primary Outcome Measures :
  1. Changes in Beck Anxiety Inventory BAI [ Time Frame: Screening to week 16 ]

    Measures 21 items in physical and cognitive anxiety ranges 0-7 mild, to 26-63 severe

    Questionnaire BDI-11

  2. Changes in Beck Depression Inventory 02 - BDI-II [ Time Frame: screening to week 16 ]
    Measures 21 items in the presence and severity of depressive symptoms 0-9 no depression, 10 -18 mild depression, 19-29 moderate to severe depression

Secondary Outcome Measures :
  1. Change in the European Quality of life 5 dimensions- EQ-5D [ Time Frame: screening to week 16 ]
    changes between the intervention PSIL-428 and placebo groups for mobility, self-care, pain & discomfort, usual activities and anxiety & depression

  2. Cognitive flexibility, using the Stroop Color & Word Test (SCWT) [ Time Frame: Screening to week 16 ]
    Changes in cognition between the PSIL-428 and placebo groups in the reading of words as compared to identifying & naming colors. A stopwatch is used and the test-taker reads color words or names ink colors from different pages as quickly as possible. An interference score, cognitive flexibility, creativity and reaction to cognitive pressure are measured

  3. Changes in resilience using the Brief Resiliency Scale [ Time Frame: Screening to 16 weeks ]
    assesses the ability of the individual to bounce back or recover from stress a score of one means low resiliency and a score of 5 means high resiliency

  4. Measurement of higher level cognitive processes using the Wisconsin Card Sorting Test [ Time Frame: screen to 16 weeks ]
    Uses two card packs, having 4 stimulus cards and 64 response cards measures attention, perseverance , abstract thinking and set shifting.

  5. The incidence of adverse events [ Time Frame: Screening to 16 weeks ]
    The number of reported cases of adverse events

  6. The severity of adverse events [ Time Frame: Screening to 16 weeks ]
    Adverse events which range from mild,moderate, severe and lethal

    Blood pressure which is consistently above and below120/80

  8. Incidence of abnormal heart rate [ Time Frame: Screening to 16 weeks ]
    The incidence of atrial fibrillation, supraventricular tachycardia or bradycardia

  9. incidence of irregular heart rate [ Time Frame: Screening to 16 weeks ]
    incidence of arrhythmias

  10. incidence of suicidal ideation using the Columbian Suicide Severity Rating Scale [ Time Frame: Screening to 16 weeks ]
    Measures Suicidal Ideation items 1-5; Suicidal Behavior 6-10 and both Suicidal Ideation and Behavior Items 1-10
