As a psychologist working with older adults, I often collaborate with neurologists and primary care providers. This course deepened my understanding of the biological processes behind cognitive aging and dementia in a way that enhances my therapeutic approach. The discussion on cognitive reserve and how lifestyle, social interaction, and education affect brain resilience really hit home for me. I also found the session on racial disparities and social determinants to be crucial. It’s rare to find a course that integrates neuroscience, psychology, and public health so seamlessly. I now feel better equipped to contribute to multidisciplinary teams and advocate for holistic treatment plans.
