Early intervention for cognitive decline: can cognitive training be used as a selective prevention technique?

CT offers promise as a preventive therapeutic technique in healthy older adults and particularly as a secondary prevention method for "at risk" groups. Future investigations need to focus on methodological constraints and delineating possible neuroplastic mechanisms of action. Nonetheless, CT programs may represent a viable, non-pharmacological early intervention strategy, as they are easily-implemented, engaging and promote social interaction in group settings.
