1. (Noninvasive) Brain Stimulation offers valuable
translatable perturbation biomarkers to bridge the
model systems to humans
2. Characterization of the dynamics of such circuits can
provide novel insights into the neurobiology of
neuropsychiatric diseases and offer new individualized
therapeutic opportunities

To better understand lifestyle determinants and their mechanisms leading to optimal
brain function in advanced age.
Prospective on the Catalonia (Barcelona) population 2014
Josefson et al. JAGS 2012•Population is ageing
•Ageing is an important risk factor for major brain diseases
•Brain diseases are #1 leading cause of disability Maintenance of optimal cognitive performance occurs
in around 20% of elders.

In summary…..
• The BBHI combines a follow-up study cohort and a multimodal intervention to
investigate the impact of positive lifestyles on brain health.
• The study is focused on middle-aged healthy individuals and incorporates
biological-based measures for the investigation of the mechanisms through
with such lifestyles exert its effects.
• It provides individual web-based/APP feedback to participants and uses mobile
Health technologies and a personalized coach approaches, aiming to increase
engagement and adherence.
