**Background:** The COVID-19 pandemic disproportionately affected older adults through both direct infection risk and the consequences of social isolation and lockdown measures. While much research focused on negative outcomes, few studies examined whether healthy older adults could maintain or improve neuropsychological functioning during the pandemic. Cognitive reserve (CR)—the brain's resilience to age-related changes—may protect against cognitive decline and emotional dysregulation. This study leveraged pre-pandemic data from a cohort of older adults enrolled in the University of the Third Age (UNITRE) in Turin, Italy, to assess longitudinal changes in cognition, mood, physical status, and emotional regulation during the pandemic.
**Methods:** From April to October 2019, 81 volunteers (60–80 years) from UNITRE underwent baseline neuropsychological assessment. After pandemic restrictions, 39 subjects (31 women; mean age 70.72 years, SD 5.62; mean education 13.28 years, SD 2.14) completed follow-up assessment between June and October 2021. Thirty-five subjects also participated in a psychophysiological assessment (October–December 2021) measuring heart rate variability (HRV) during presentation of 75 pandemic-related images. The neuropsychological battery assessed global cognition (ACE-R, MMSE), executive function (MoCA, TMT parts A and B), memory (RMT—15 immediate and delayed words), language comprehension (Token Test), mood (AES, BDI, HARS, MAS, DIS), and physical frailty (Fried phenotype, CIRS). Bayes factors (BFs) and paired t-tests compared pre- and during-pandemic measures. Correlation and multiple regression analyses examined relationships between neuropsychological changes and emotional (dys)regulation indexed by the LF/HF ratio of HRV.
**Key Results:** Participants showed significant improvements in global cognition (ACE-R: t = −2.952, p = 0.006), executive function (MoCA: t = −2.609, p = 0.013), and language comprehension (TT: t = −4.70, p = 0.001). Bayes factors confirmed stability in memory (RMT immediate: BF01 = 4.14; delayed: BF01 = 4.33), attention (TMT part A: BF01 = 5.46; part B: BF01 = 3.53; B-A: BF01 = 3.15), and global cognition (MMSE: BF01 = 4.22). Mood measures showed significant increases in apathy (AES: t = −7.43, p < 0.001) and anxiety (HARS: t = −3.71, p < 0.001), with 36% of the sample scoring below cut-off on AES and 13% on HARS during the pandemic. Depression (BDI: BF01 = 5.33), hypomania (MAS: BF01 = 5.51), and disinhibition (DIS: BF01 = 3.07) remained stable. Physical frailty status did not change significantly (McNemar χ² = 2.29, p = 0.515). The correlation matrix showed significant associations between LF/HF ratio and both AES (p < 0.05) and ACE-R (p < 0.05). A multiple regression model (R = 0.711, R² = 0.506) revealed that higher apathy was significantly predicted by lower ACE-R scores (t = −2.391, p = 0.024), higher HARS scores (t = 3.704, p = 0.001), and higher LF/HF ratio (t = 3.011, p = 0.006), while gender (p = 0.540) and age (p = 0.534) were not significant predictors.
**Clinical Implications:** This study provides novel evidence that healthy older adults can maintain or even improve cognitive function during a major health crisis when they remain socially and educationally engaged. The findings highlight the protective role of cognitive reserve against pandemic-related emotional dysregulation and apathy. The UNITRE model—combining cognitive stimulation, social interaction, and physical activity—represents a scalable intervention to promote healthy aging and resilience. These results are particularly relevant given global demographic trends (by 2050, 2 billion people will be over 60) and the need for evidence-based strategies to support cognitive health during future health emergencies. Limitations include the small sample size (n = 39), predominantly female and medium-to-high socioeconomic status participants, and the lack of a control group not engaged in similar programs.
