Digital Biomarkers for Cognitive Disorders

Julie Carty

In a data-rich world, digital biomarkers have the potential to reduce costs, and improve patient outcomes. But what is a digital biomarker? Today we decided to take a look at the third and final topic that will feature in the HealthXL Global Gathering on February 22-23 in Basel Switzerland, Digital Biomarkers for Cognitive Disorders. We took a look at some of the innovations and companies that are developing the solutions of tomorrow, but first, what is a biomarker?

What is a Biomarker?

Simply put a biomarker is a measurable indicator of the severity or presence of some disease state. Thus, a digital biomarker is a measurable indicator of some disease state that is determined using a connected digital device. We decided to take a closer look at some of the companies and innovations in the space. Check it out below!

Why are we talking about it?

Cognitive disorders, often not well understood, are a disease category that has the potential to be impacted by digital biomarkers. Take for example a person with diagnosed with Parkinson’s Disease, they develop the disease from a complex interaction between their genotype and environment which leads to the parkinson’s phenotype: Tremor, Bradykinesia, postural instability. The beauty of digital biomarkers comes from when they can be deployed to objectively detect these phenotypes which can usually only be detected subjectively by a doctor later on in the progression of the disease. Check out three companies that we have found that are making strides within this nascent space:

Companies to watch that are innovating in the space


Neurotrack’s first product, Imprint, released early this year, is a digital cognitive test that enables earlier and more effective evaluation of patients who may be at risk for cognitive decline. Imprint is a 5-minute web-based test that uses eye-tracking technology to assess brain function. Neurotrack has raised $8 million in funding to date and recently partnered with Welkin Health for a Study on Advanced Solutions for Individuals At Risk for Cognitive Decline.


Akili is building a clinically validated, cognitive therapeutic assessment and diagnostic tool that looks and feels like a video game. Akili’s leading project, EVO is currently being evaluated in the STARS-ADHD study. They have raised $73 million in funding to date.


Neurametrix detects and monitors brain diseases, disorders, and injuries with non-invasive software that measures sub-clinical human cognitive and motor function based on typing cadence. The solution is so sensitive it notices inconsistencies in typing cadence that would usually go unnoticed by the naked eye.

What’s a Rich Text element?

The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.

Static and dynamic content editing

A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!

How to customize formatting for each rich text

Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.
