Prevention of cognitive decline in subjective cognitive decline APOE ε4 carriers after EGCG and a multimodal intervention (PENSA): Study design

Background: Education could offer a protective effect on cognition in individuals with Subjective Cognitive Decline (SCD), which is considered to be the early stage of Alzheimer’s Dis- ease (AD). However, the effect of education on cognition in SCD individuals with SCD-plus fea- tures is not clear. Objective: The aim of the study was to explore the effect of education on cognition in SCD individ- uals with SCD-plus features. Methods: A total of 234 individuals with SCD were included from the Sino Longitudinal Study on Cognitive Decline (SILCODE). Cognition was assessed across 4 domains (memory, executive, lan- guage, and general cognitive functions). Multiple linear regression models were constructed to ex- amine the effect of education on cognitive scores in individuals without worry (n=91) and with wor- ry (n=143). Furthermore, we assessed differences in effects between APOE ε4 noncarriers and APOE ε4 carriers in both groups. Results : Multiple linear regression analysis showed a positive effect of education on memory, ex- ecutive, and language cognition in individuals without worry and all cognitive domains in individu- als with worry. Furthermore, we found a positive effect of education on executive cognition in APOE ε4 noncarriers without worry and language and general cognition in APOE ε4 carriers with- out worry. Meanwhile, education had a positive effect on all cognitive domains in APOE ε4 noncar- riers with worry and executive, language, and general cognition in APOE ε4 carriers with worry. Conclusion: This study indicates that education has the potential to delay or reduce cognitive dec- line in SCD individuals with SCD-plus features.

Background: Some genes could interact with cardiovascular risk factors in the development of Alzheimer’s disease. We aimed to evaluate the interaction between ApoE ε4 status, Clock T3111C and Per2 C111G polymorphisms with cardiovascular profile in Subjective Cognitive Decline (SCD) and Mild Cognitive Impairment (MCI). Methods: We included 68 patients who underwent clinical evaluation; neuropsychological assessment; ApoE, Clock and Per2 genotyping at baseline; and neuropsychological follow-up every 12–24 months for a mean of 13 years. We considered subjects who developed AD and non-converters. Results: Clock T3111C was detected in 47% of cases, Per2 C111G in 19% of cases. ApoE ε4 carriers presented higher risk of heart disease; Clock C-carriers were more frequently smokers than non C-carriers. During the follow-up, 17 patients progressed to AD. Age at baseline, ApoE ε 4 and dyslipidemia increased the risk of conversion to AD. ApoE ε4 carriers with history of dyslipidemia showed higher risk to convert to AD compared to ApoE ε4− groups and ApoE ε4+ without dyslipidemia patients. Clock C-carriers with history of blood hypertension had a higher risk of conversion to AD. Conclusions: ApoE and Clock T3111C seem to interact with cardiovascular risk factors in SCD and MCI patients influencing the progression to AD.
