The study involved Information and Communication Technologies (ICT) and more specifically computer exercises blended with game activities. It was hypothesized that ICT facilitated, game blended combined cognitive and physical exercise improves global cognition when compared to a control group; and that the number of sessions within exercising participants predict cognitive benefits. In addition, we explored the impact of potential moderators on combined exercise-induced cognitive benefits.

The multicenter study was part of the Long Lasting Memories (LLM) project (www.longlastingmemories.eu), which was funded by the European Commission (Information and Communication Technologies Policy Support Program (ICT-PSP) for a three year period (2009-2012). It used a pre-post-test design with the between-participant factor group [intervention vs. passive control]. Post-test was conducted within 2 weeks after completion of the exercise period. Interventions were carried out in Athens and Thessaloniki (Greece) within day care centers, hospitals, senior care centers, a memory outpatient center, local parishes, at university campus facilities (university community installations), and at participants' homes.

Institutions had to provide at least 5 exercise weeks, with a frequency of at least 1 physical and 2 cognitive exercise sessions per week, resulting in at least 5 physical and 10 cognitive exercise sessions in total.

Inclusion Criteria:

no severe cognitive impairment [Mini-Mental State Examination, MMSE ≥ 18], fluent language skills, agreement of a medical doctor and time commitment to the test and exercise protocol.

Exclusion Criteria:

concurrent participation in another study, severe physical or psychological disorders which precluded participation in the intervention (i.e., inability to follow instructions), unrecovered neurological disorders such as stroke, traumatic brain injury, unstable medication within the past three months, severe and uncorrectable vision problems, or hearing aid for less than three months.
