Brief summary: Neurophysilogical, neuropsychological evaluation and cognitive and physical training

Detailed description: 24 sessions (8 weeks, 3 times per week) of cognitive and physical training via computer. Each session consisted of 45 minutes of cognitive traing (BrainHQ platform https://www.brainhq.com/) and 45 minutes of physical training (FitForAll platform https://www.fitforall.gr/play/app/). Cognitive training included memory, attention, velocity, intelligence etc. Physical training included aerobic, strength flexibility and other excercises. All evaluations were performed 1-14 before the initiation of the interventions and 1-14 after their completion. Neurophysiological evaluation consisted of EEG with the use of 128 electrode-machine and the protocol included 5 minuted of eyes closed and 5 minutes of eyes open. Neuropsychological evaluation included Trail Making Test (A \& B), Verbal Fluency, Stroop test, Wechsler Memory - Cubes (visuospatial), MoCA, FAB (Screening for frontal damage) and Eyes Test (Theory of Mind). Also, the physical condition evaluation included 6-Minute Walking Distance (6MWD), ΒΜΙ, HandGrip Strength Test, Short Physical Performance Battery Protocol.
