Dementia Matters

How much does it cost to live with dementia in the United States? The hidden costs are often overlooked, but these numbers and trends are important to understand in order to inform the public and effectively allocate resources. Dr. Julie Zissimopoulos leads the United States Cost of Dementia Project, where they recently published a report on the total cost of dementia in 2025. Dr. Zissimopoulos joins the podcast to discuss the report’s findings and analyze what this means for patients and families, as well as for public policy, in the future.

Everyone has habits. Some are beneficial for brain health while others are less so, but it turns out that habits as simple as brushing your teeth at the same time each morning can help your brain adapt to changes from cognitive impairment. Dr. Gordon Giles joins the podcast to dive into the fascinating world of neurological rehabilitation and how building small, consistent habits can rewire the brain and support healthy lifestyle choices. He also gives a sneak peek into his upcoming talk for the Healthy Living with Mild Cognitive Impairment (MCI) program titled “Unlocking the Power of Habits, Routines and Strategies.”

Holistic medicine, alternative medicine, complementary medicine – you may have heard these terms or seen them used online and wondered what they mean. Each term refers to the concept of integrative medicine, a comprehensive approach to healthcare that focuses on treating a person’s mind, body and spirit rather than addressing symptoms or a specific disease through a combination of medical treatments and other evidence-based therapies. By integrating practices like nutrition, mindfulness, supplements and other alternative therapies with traditional care, integrative medicine aims to promote overall wellness, enhance healing and improve quality of life, especially for individuals managing chronic conditions like dementia. Dr. David Rakel, a leader in integrative medicine, joins the podcast to share about how this holistic approach can help people experiencing memory change and how diet, mindset and lifestyle can play a crucial role in supporting brain health.

Dementia diagnoses affect families in many different ways. One of the most challenging to navigate is that of younger-onset dementia (YOD), a form of dementia that affects someone below the age of 65. This diagnosis can be particularly jarring for young families, as resources, support and research for this form of dementia are limited. When Diana Cose’s husband Lorenzo received this diagnosis, she decided to change that by founding Lorenzo’s House, a nonprofit that supports families grappling with younger-onset dementia and works toward lessening the stigma surrounding it. Diana Cose joins the podcast with programs lead Patti LeFleur to share their experiences with younger-onset dementia and how Lorenzo’s House brings light in the darkness.

Guests: Diana Cose, founding executive director, Lorenzo’s House, and Patti LeFleur, youth and lighthouse outreach lead, Lorenzo’s House

What exactly does a mild cognitive impairment (MCI) diagnosis mean, and what should you do after receiving one? Hearing this diagnosis from a doctor can bring up a lot of emotions and questions for individuals and family members. Jennifer McAlister joins Dementia Matters to offer advice for next steps after receiving an MCI diagnosis and share strategies and resources that have been successful for individuals she’s worked with over the course of her career.
