Exploring Research on Alzheimer’s Disease and other Types of Dementia
Welcome to Minding Memory. In this podcast we discuss topics related to dementia research. This is an all-hands-on-deck moment for dementia research, and we have topics for both those new to the space as well as old pros. We start with some basics, like: What exactly is dementia? What are the different types of dementia? What is the TICS, if not a swarm of blood-sucking insects? But we also invite researchers on to discuss their interesting work to give you a glimpse at the questions, data, and methods moving the field forward.
Minding Memory is co-hosted by Matthew Davis and Donovan Maust. Matt and Donovan are Associate Professors and health services researchers at the University of Michigan. Matt’s PhD is in data science and Donovan is a psychiatrist.

Has the Likelihood of Receiving a Dementia Diagnosis at the End of Life Changed?
In this episode we’ll speak with Dr. Julie Bynum who was the senior author on a recent study that examined how the likelihood of receiving a diagnosis of dementia has changed over the last decade or so. We’ll discuss what this might mean clinically and what researchers that rely on Medicare data should take-away from this finding. We also will talk in general about the various approaches that exist for identification of dementia in Medicare billing data.

Personality Type and Cognitive Resilience
In this episode we discuss what’s known about the association between personality type and cognitive function. Further, the idea of resilience—or what protects the cognition of individuals with a high level of neuropathology associated with cognitive decline—might have important implications for dementia prevention. Our guests are Dr. Eileen Graham and Dr. Dan Mroczek. Drs. Graham and Mroczek are both faculty at Northwestern University with interests in how personality factors influence physical and cognitive health over the life course.

The Secret Life of a Health Data Analyst
Health data analysts are an elusive bunch in the wild. While we see their names periodically show up as middle authors on manuscripts or in the Acknowledgement section they work largely behind the scenes; yet they play a vital role in conducting research that use large data. In this episode we speak with several health data analysts to better understand the role they play in research and, for all the researchers out there, discuss how to make the process as smooth as possible when working with an analyst.

Healthcare at Home for People Living with Dementia
This week we feature a recent study by Katherine Ornstein and colleagues that was published in the Journal of the American Geriatrics Society. Dr. Ornstein studies family caregiving and the home-based clinical care. The study used Medicare claims linked to the National Health and Aging Trends Study to estimate the degree to which people living with dementia use health services from home. We’ll discuss what exactly home-based health services are (and how they are typically categorized) and discuss the role these services are expected to play for people living with dementia.

Cognitive Impairment and Susceptibility to Scams
For older adults living with dementia, cognitive impairment can lead to susceptibility to fraudulent activities. In this episode we’ll discuss with Dr. Duke Han from the Keck School of Medicine at USC what’s known about the intersection of aging, cognition, and susceptibility to scams.

Dementia as a Cause of Death
Causes of death were reclassified by the CDC to include contributing factors such as dementia. These changes resulted in dementia jumping up from the 8th cause of death in 2000 to the 6th cause of death in 2018 (and the 5th cause of death among older adults). In this episode we’ll talk with Dr. Bryan James from Rush University about dementia as a cause of death (versus contributing factor).

What is the Value of Early Detection of Dementia?
In this episode we talk with Dr. Ken Langa about the implications of identification of “preclinical” Alzheimer’s disease (situations where individuals may have biological signs of Alzheimer’s but no symptoms). Ken is a leading dementia researcher and our discussion focuses on an article he published called “Preclinical Alzheimer Disease – Early Diagnosis or Overdiagnosis” that was published in JAMA Internal Medicine. In his article co-authored with Dr. Jim Burke, he brings up some of the potential indirect effects of early detection.

Could the FDA’s Approval of a New Drug to Treat Alzheimer’s Disease do More Harm than Good?
Aducanumab is a new drug designed to remove amyloid in the brain. Following an accelerated process, the Food and Drug Administration approved Aducanumab as a treatment for Alzheimer’s disease despite (what many experts feel) little evidence of effectiveness. In this episode we discuss the approval of Aducanumab with Dr. Jason Karlawish from the University of Pennsylvania and talk about what it could mean for drug discovery going forward.

What are the Different Types of Dementia? A Primer for those of us who aren’t Healthcare Clinicians
Often research studies consider dementia as either present or absent, while others specify particular types of dementia. For example, what exactly is frontotemporal dementia? In this episode, we talk with Dr. Henry (Hank) Paulson, who directs the Michigan Alzheimer’s Disease Center, to introduce listeners to the most common types of dementia and hear about some of their defining features. For those of you without clinical backgrounds, consider this your crash course on the types of dementia.

Keep it Down out There: You’re Hurting my Brain
Our guest in this episode is Dr. Sara Adar. She is an associate professor at the University of Michigan School of Public Health in the department of epidemiology. Dr. Adar was the senior author on a study titled “Long-term community noise exposure in relation to dementia, cognition, and cognitive decline in older adults” that was published in the journal Alzheimer’s & Dementia. The study used data from the Chicago Health and Aging Project to examine the association between exposure to community noise and cognitive impairment. We talk with her about how exposure to noise affects cognition.

Drugs and Dementia: The Good, the Bad, and the Ugly
While there are some FDA-approved medications for dementia, more individuals living with dementia are actually prescribed psychotropic medications. In this episode, Donovan introduces Matt to the concept of the behavioral and psychological symptoms of dementia, which are just as much part of dementia as the memory loss—and are probably a big reason for all this other prescribing.

Donovan Takes the Telephone Interview for Cognitive Status
One of the richest data sources available to study cognition and aging is the Health and Retirement Study (HRS). This nationally representative survey includes questions to help assess cognition, but many researchers may use this data without actually knowing the questions behind the variables—don’t be That Guy! (or Gal!) Listen to Dr. Lindsay Ryan, an HRS team member, coach Matt as he administers the Telephone Interview for Cognitive Status (TICS) to Donovan, who is surprisingly good at recalling types of birds.

The Study Most Often Cited in the First Sentence of Dementia Research Papers
If you’re new to dementia research, you’ll soon come to find that most research papers on dementia start off something like this: “In the United States there are 5.8 million individuals living with dementia and this is expected to increase to 13 million by 2015. . . .” In this episode we discuss the study on dementia prevalence that has been cited thousands of times with one of the authors. Dr. Jennifer Weuve from Boston University joins us today. We also talk more broadly about what makes a research paper highly citable in general.
