The aim of the present study was to investigate the association of prodromal PD (pPD) with trajectories of healthy aging, according to its latest definition by the WHO. In a sample of 1,226 older adults (704 women), PD diagnosis was reached through standard clinical research procedures. Probability of pPD was calculated according to the International Parkinson and Movement Disorder Society's research criteria for PD-free participants.

Methods: The dataset of the Hellenic Longitudinal Investigation of Aging and Diet was the basis for the present longitudinal analysis. In a sample of 1226 older (> 65 years) adults (704 women), adherence to the Mediterranean diet was assessed through the calculation of the MedDietScore.
Prevalence of dementia or of milder form of cognitive impairment is increasing and a pharmaceutical treatment remains pending. These facts underline the need of identifying modifiable factors and targeted interventions that could reduce the incidence or control disease progression. Physical activity (PA) has been shown to have a beneficial effect on cognitive function, however findings to date remain controversial.

The aim of this study was to identify latent groups following similar trajectories in cognitive performance assessed with the verbal fluency test, as well as their determinants.
Methods: Data from English Longitudinal Study of Aging (ELSA) were studied.
The aim of this study was to evaluate several sociodemographic, lifestyle, and clinical characteristics of the IKARIA study participants and to find healthy aging trajectories of multimorbidity of Ikarian islanders. During 2009, 1410 people (aged 30+) from Ikaria Island, Greece, were voluntarily enrolled in the IKARIA study. Multimorbidity was defined as the combination of at least two of the following chronic diseases: hypertension; hypercholesterolemia; diabetes; obesity; cancer; CVD; osteoporosis; thyroid, renal, and chronic obstructive pulmonary disease.

- - The study aimed to identify different patterns of processing speed changes as people age and what factors influence these patterns, using data from nearly 12,100 participants in the English Longitudinal Study of Aging (ELSA) as part of the ATHLOS project.
- - Four distinct trajectory groups were found: High, Middle/Stable, Low/Stable, and Low Decline, with various demographic and health factors influencing membership in these groups.
- - Factors such as female gender, higher education, mild physical activity, marital status, and wealth were linked to better processing speeds, while health issues like cardiovascular disease and depression were associated with lower scores, indicating potential intervention targets to help combat cognitive decline.
