SUMMARY

# Lifestyle Intervention Mechanisms in Alzheimer's Disease ## Background and Rationale Alzheimer's disease (AD) affects over 55 million people worldwide, with limited therapeutic options. Epidemiological studies consistently demonstrate that lifestyle interventions including physical exercise, cognitive stimulation, Mediterranean diet, and social engagement reduce AD risk by 30-60%. However, the underlying molecular mechanisms remain poorly characterized, limiting translation into evidence-based

METHODOLOGY NOTES

Phase 1 (Weeks 1-2): Randomize 200 5xFAD mice (8 weeks old) into 8 groups (n=25 each): control, exercise-only, cognitive-only, diet-only, social-only, and three combination groups. Establish baseline measurements via Morris water maze, novel object recognition, and blood biomarker collection. Phase 2 (Weeks 3-14): Implement interventions - exercise group receives 24/7 voluntary wheel access; cognitive group undergoes daily 30-minute enrichment sessions with rotating novel objects and puzzle feeders; diet group receives custom chow with 2% omega-3 fatty acids, curcumin (500mg/kg), and resveratrol (200mg/kg); social group housed in larger cages (6 mice vs 3 controls) with tunnels and platforms. Phase 3 (Weeks 8, 12, 16): Conduct behavioral testing batteries including Morris water maze, Y-maze spontaneous alternation, novel object recognition, and elevated plus maze. Collect blood samples for ELISA-based biomarker analysis (Aβ40/42, p-tau, GFAP, NFL). Phase 4 (Week 16): Terminal sacrifice
