Apple Explores Dementia Detection Using Apple Watch and iPhone Sensor Data in Collaboration with Eli Lilly and Evidation Health

As we all know, since the Apple Watch Series 4, Apple has sought to pivot into the health and medical sector, endowing wearable devices with more practical functionalities. The surge in Apple Watch sales appears to further validate that this strategic direction was indeed the right choice.

Now, there are reports that Apple is trying to innovate in the healthcare sector. In the future, the Apple Watch may be able to detect dementia. According to MacRumors, a research paper titled "Developing Real-World Measures of Cognitive Impairment from Consumer-Grade Multimodal Sensor Streams" revealed this information.

According to the paper abstract, Apple Inc. has partnered with pharmaceutical company Eli Lilly and health startup Evidation Health in an effort to detect early symptoms of dementia using data collected from iPhones and Apple Watches. It is reported that these companies monitored 31 individuals with cognitive impairment and 82 individuals without cognitive impairment over a 12-week period, collecting 16 TB of data.

Analysis reveals that individuals exhibiting symptoms of cognitive decline demonstrate slower input speeds, fewer keystrokes, greater reliance on assistive applications, and reduced frequency of text messaging. These metrics are sufficient to distinguish individuals with early-stage cognitive impairment from healthy controls.

In response, Christine Lemke, co-founder of Evidation, stated, “Through this study, we analyzed how daily behavioral data—such as that captured by iPhones, Apple Watches, and Beddit sleep monitors—can effectively distinguish patients with mild cognitive impairment and early Alzheimer’s disease from asymptomatic individuals.”

At first glance, the notion that a compact smartphone or smartwatch could successfully detect dementia is truly jaw-dropping. Yet, in today’s era of rapid technological advancement, nothing is impossible; there is only what we have yet to imagine, not what tech giants cannot achieve. Optimistically speaking, if future iPhones or Apple Watches were to integrate dementia detection features, it would undoubtedly be a positive development. After all, early detection and diagnosis can better help patients manage symptoms and improve their quality of life.

The key question now is when Apple’s proposal to use smartwatch sensor data and activity information to identify the “physiological and behavioral characteristics of cognitive impairment” will truly be implemented, bringing hope to dementia patients worldwide?
