Friday 03 November 2023Guttmann Cognitest®, preliminary validation of a digital solution to test cognitive performance
Frontiers in Aging Neuroscience
The study validated the "Guttmann Cognitest", a digital solution for cognitive assessment, by comparing it with traditional neuropsychological tests. 274 individuals of different ages participated in the study. The results showed that the Cognitest measures four main cognitive domains, negatively correlates with age, is related to educational level, and has a gender effect. It was concluded that this digital solution is useful for assessing cognitive functioning in large population samples.
Sunday 15 October 2023Functional connectivity mediates the relationship between cardiorespiratory fitness and stress in midlife.
Mental Health and Physical Activity
The study investigates the relationship between cardiovascular fitness, functional brain connectivity, and mental health in middle-aged adults. Data from 418 participants from the BBHI were analyzed, revealing that higher cardiovascular fitness was associated with lower symptoms of anxiety and stress. Additionally, it was found that functional connectivity within the Default Mode Network (DMN) and between the Frontoparietal Network (FPN) and the Salience Network (SN) mediated the relationship between cardiovascular fitness and stress. These findings suggest that cardiovascular fitness can positively impact mental health in middle age through functional brain connectivity.

Thursday 17 August 2023Brain Connectivity Correlates of Cognitive Dispersion in a Healthy Middle-Aged Population: Influence of Subjective Cognitive Complaints
The Journals of Gerontology: Series B
The study examines cognitive dispersion, which represents fluctuations in cognitive performance within an individual, in middle-aged adults. 520 healthy volunteers from the Barcelona Brain Health Initiative, aged 40-66, were analyzed and stratified into high and low subjective cognitive complaints (SCC) groups. It was found that cognitive dispersion was negatively related to cognitive performance and resting-state functional connectivity of brain networks but not to white matter integrity. These associations were stronger in those with high SCC, suggesting that cognitive dispersion may serve as an early indicator of age-related cognitive and functional changes in middle age.
Friday 14 July 2023Remote cognitive assessment to early detection of cognitive decline
The increase in life expectancy has led to a significant rise in the aging population, which poses a substantial challenge for public health. Age-related cognitive decline is a pressing issue, with a growing number of initiatives seeking early detection and intervention strategies. Self-administered computerized cognitive assessments, like "Gutmann Cognitest," offer a cost-effective and scalable solution for population-wide screenings in middle to old-aged adults. They can identify subtle cognitive changes, facilitating early interventions or monitoring cognitive function in diagnosed individuals over time. These digital tools will play a vital role in providing efficient clinical services and tracking cognitive functioning in an aging world.
Monday 17 April 2023COVID-19 after two years: trajectories of different components of mental health in the Spanish population
Epidemiology and Psychiatric Sciences
Our study aimed to identify trajectories for different components of mental health during a two-year follow-up of the COVID-19 pandemic, contextualizing them according to pandemic periods. We investigated the associations between mental health trajectories and various exposures, determining if differences existed among different mental health outcomes regarding these associations. We identified three latent trajectories for the studied outcomes, distinguishing between 'resilient' and 'chronic-worsening.' Overall, global health, cognitive health, and coping strategies were identified as common protective factors. Our results support heterogeneity in reactions to the pandemic and the need to study different mental health components over a longer follow-up. Understanding modifiable protective and risk factors associated with these trajectories would allow targeted interventions for specific population segments.

Thursday 16 March 2023Brain system segregation and pain catastrophizing in chronic pain progression
Frontiers in Neuroscience
The study investigates the association between pain catastrophizing, brain system segregation, and the progression of chronic pain. It found that higher levels of catastrophizing and lower segregation of brain networks were strongly associated with a worsening in pain experience over time. These findings suggest that approaches focusing on these factors could minimize the impact of chronic pain on daily life activities.
