Best of: Computational modeling can help us understand Alzheimer’s disease

We’re re-running an important episode on Alzheimer’s disease — a topic that touches many people. We still don’t have a complete understanding of the disease and that makes it hard to design effective therapies. In 2022, Russ Altman sat down with mechanical engineer Ellen Kuhl who offered a glimpse into the way she’s using computational modeling to help improve our understanding of Alzheimer’s disease.

Chapters:

(00:00:00) Introduction 
Russ introduces the episode on Alzheimer's disease, highlighting its global impact, challenges treating it, and Dr. Ellen Kuhl’s research on it.

(00:02:08) The Approach and Research Methods
Ellen Kuhl discusses her lab's interdisciplinary approach, and method of using existing data to create dynamic models to study the brain's lifecycle and degeneration in Alzheimer's disease.

(00:03:46) Key Features of Alzheimer's Disease and Detection
Biomarkers of Alzheimer's, their role in brain cell death and cognitive decline, and the possibilities for early detection methods of these protein issues.

(00:07:20) How Computational Models Function
How the models integrate various data points and physics principles to comprehensively understand Alzheimer's progression.

(00:08:43) Spread of the Disease
Exploring the mechanisms of how Alzheimer's spreads from cell to cell in the brain, and the progression through the lobes of the brain, regardless of the cause genetic or trauma induced.

(00:12:33) Interdisciplinary Collaboration 
The challenges and benefits of working as a mechanical engineer in Alzheimer's research and the opportunities of a multidisciplinary approach.

(00:14:33) Alzheimer's Drug Development 
Modeling a controversial Alzheimer's drug, its potential impact, and the importance of early diagnosis for effective treatment.

(00:16:04) Transition to COVID Research and Modeling
How the Alzheimer's model was rapidly adapated to study the spread of COVID-19, drawing parallels between brain regions and city networks.

(00:18:38) Covid Modeling Learnings and Applications
How their COVID models highlighted the importance of asymptomatic transmission and helped governments with reopening strategies.

(00:20:24) Responsible Model Application 
The rampant and at times irresponsible use of  models during the pandemic, and metrics for measuring credibility of models

(00:23:59) COVID Data Sharing
The positive legacy of COVID-19, focusing on the accelerated progress facilitated by open and transparent data sharing.

(00:24:53) Model Interpretability and Closing
Insights into the importance of model interpretability and the value of reducing complexity to enhance understanding.
