  1. BRAIN FITNESSClinical Trial to measure the effect of cognitive training in the brain’s abilities

  2. The scientific investigation as a process: • 1. Formulation of the question • 2. Study Design • 3. Selection of data sources • 4. Selection of participants • 5. Protocol draft • 6. Data collection* • 7. Data processing and analysis* • 8. Dissemination of results* * 2nd semester

  3. 1. Formulation of the question Can “brain exercise” develop the brain’s performance, in younger people?

  4. 2. Study Design CLINICAL TRIAL Objective - Testing the influence of exercise programs in : - Memory - Concentration - Speed of processing In a clinical trial, the BLINDING is as important as the RANDOMIZATION. Blinding/Double Blinding – Impossible (in this clinical trial) Randomization – Possible: Division of the participants in two groups – Experimental Group and Control Group

  5. 3. Selection of data sources • 67 Neuropsychological tests found; • Excluded those who didn’t measure: • Memory; • Concentration; • Speed of Processing; • Problems with the remaining tests: • Too expensive; • Usually used/focused on elderly people; • Usually not applied to healthy individuals; • TOMAL; WAIS-III; d2 Test of Attention; • Problem finding applicable tests;

  6. 4. Selection of participants • Inclusion criteria: • - 1st year ‘s students, Medicine, FMUP • Exclusion criteria: • - Class 13 1st year • - Mental diseases • - Age < 17 • - Age > 19 • - Not having internet at home The participant is volunteer; Questionary about basal variables (age,sex…) to further analysis; The participant is considered eligible for inclusion; The participant joins the study; Randomization in two groups. The number of participants will be determined as soon as we confirm the kind of test that we’ll apply.

  7. 5. Protocol draft • - Studies/clinical trials on this matter are mainly about: • - the elderly • - keeping the brain fit and functional; • Our clinical trial aims to draw some conclusions about : • younger people; • developing the brain’s abilities; • Training method: Online daily brain training program; • Evaluation method: Offline written tests (pretest and final test); • Expected results: Some improvement in the experimental group’s test results comparing to those of the control group;
