Linus Health raises $55M for early screening for Alzheimer’s illness

Linus Health, a digital well being firm focused on enhancing brain well being, has raised $55 million in funding for screening tools to diagnose dementia and Alzheimer’s illness.

Morningside Ventures led the round, and current investors participated. The funds will allow Boston-based Linus Health to develop its group and accelerate the development of its platform to address the urgent will need for cognitive screenings and insights as the prevalence of dementia grows to more than a million diagnoses per year in the U.S. alone.

Linus’ platform provides an accessible, noninvasive, and time-effective system to assess cognitive well being, which includes pre-symptomatic detection of cognitive impairment, which optimizes interventional outcomes and advances analysis capabilities.

The funding news follows a string of research that validate the efficacy of the Linus platform in detecting cognitive illnesses, mentioned David Bates, CEO of Linus Health, in an interview with VentureBeat.

“Some reports would say Alzheimer’s disease starts to set in 20 years before it becomes clinical,” Bates mentioned. “So what are those very, very early symptoms? And through lifestyle modification, can you enable disease course modification? I’d say there’s a good body of evidence to suggest yes, you can. The sooner we can intervene, the better the outcome will be.”

A 2020 study discovered that the financial burden of Alzheimer’s illness remedy in the U.S. is estimated at $305 billion, and it is anticipated to develop to more than $1.5 trillion as the population ages. Given the staggering price of Alzheimer’s illness and associated dementias, today’s funding news comes at a important time for Linus Health and brain well being as a entire, as early diagnosis and remedy can lead to superior outcomes and reduced expenses for patients, caregivers, and well being care systems.

“We’re very committed, not just in the U.S., but globally. The thing I love the most is we have great technology and great science, but the people are very committed, and they give up other opportunities, maybe more lucrative opportunities from a salary standpoint, but they really care about this,” Bates mentioned.

Starting out

Linus Health desires to allow millions of men and women to get tests. The trouble is that it requires educated physicians time to diagnose patients in sessions for just about every particular person who demands a test for dementia or Alzheimer’s.

“About 80% of dementia is treated in primary care, but they’re not as equipped to treat it,” Bates mentioned. “They don’t have the tools and insights for the early detection.”

Bates came from venture capital, and he teamed up with a healthcare specialist. Dr. Alvaro Pascual-Leone, Linus Health’s cofounder, is a behavioral neurologist, neuroscientist, and professor of neurology at Harvard Medical School. They named the firm immediately after Linus in the Peanuts comics, as he was a sort of trusted adviser.

“Even though it’s high tech, we really want to be that trusted advisor, that friend, to everyone we serve,” Bates mentioned.

After years of searching for an investment, they began the firm themselves in 2019, focusing on assessments like one identified as DCT clock, exactly where a patient draws a clock.

“We grew rapidly because we were able to partner and license technologies like the DCT clock, which was a pretty mature digital tool,” Bates mentioned. “It was already registered with the FDA. So that was a boost that we’ve just continued to forge some really strong relationships. We looked at it not only from an objectivity and sensitivity standpoint of these tools but from scalability.”

They also wanted to make the testing more accessible and standardize detection and suggestions.

“What Linus Health does, in a nutshell, is multimodal signal detection,” Bates mentioned. “We look at people’s behavior, a variety of different standpoints, like eye-tracking, voice, motion, as well as the output. Then we extract insights from that.”

The group has about 40 men and women, which includes engineers, information scientists, and a clinical group that involves neuropsychologists, consultants, and neurologists.

While there are other cognitive screening businesses, Linus Health tries to analyze the particular person taking the test, rather than searching at the final results of a test.

“That’s why our data is much richer, more insightful,” he mentioned. “And we can do a lot more with it. And we can do it in a much shorter period of time. We use machine learning to understand what is significant, what is meaningful. And then we use the advances in science and medicine to understand how these signals tie to brain function. And we can get better insights into what the person is experiencing now and what they are experiencing over time.”

How the tests work

Researchers have utilized the Linus platform and assessments, such as the DCTclock digital clock-drawing test, to recognize the beginnings of Alzheimer’s illness pathology in their research.

Tests such as the Montreal Cognitive Assessment (MoCA) and the Clock Drawing Test (CDT) are used to detect cognitive adjust arising from a wide variety of causes, from strokes and concussions to dementias such as Alzheimer’s illness. The trouble is most tests detect the impairment in brains only immediately after it impacts people’s lives.

With Alzheimer’s, modifications in the brain could take place 10 or more years ahead of the cognitive adjust becomes noticeable, and no simply administered test can detect these modifications at the extremely earliest stage. But in current years researchers have created a predictive model that, coupled with current hardware, opens up the possibility of detecting problems such as dementia earlier than ever ahead of.

Clock-drawing test

For various decades, physicians have screened for circumstances which includes Parkinson’s and Alzheimer’s with the CDT, which asks subjects to draw an analog clock-face displaying a specified time and to copy a pre-drawn clock.

But the test has limitations for the reason that its benchmarks rely on doctors’ subjective judgments, such as figuring out whether or not a clock circle has “only minor distortion.” Researchers at MIT discovered that the Anoto Live Pen, a digitizing ballpoint pen that measures its position on the paper upwards of 80 occasions a second, can give more precise information when patients use it to draw on a tablet.

The pen gives information that is far more precise than can be measured on an ordinary drawing, and it captures timing information and facts that enables the method to analyze just about every one of a subject’s movements and hesitations. If you take a lengthy time to draw a circle, then that can be measured. Bates mentioned some of these tests can generate telling final results in a couple of minutes.

Bates mentioned that Linus Health has been in a position to do tests in the tens of thousands. But the company’s target is to scale up to millions of tests and allow some men and women to be tested repeatedly. Digital tools such as tablets can gather objective information and turn it into actionable insights.

The remedy enables care experts to monitor brain well being remotely, simply, and conveniently more than extended periods of time, even outdoors of clinical settings. Linus collects, aggregates, and analyzes information and facts drawn from information points like voice and speech patterns, visuospatial memory, dual-tasking capacity, and fine motor handle, as effectively as movement, balance, and pulmonary capacity and can hyperlink with electronic well being records to provide a extensive image of individuals’ brain well being.

More progress

Most lately, Linus’ platform was established hugely efficient in detecting early Alzheimer’s symptoms in a study from researchers at Massachusetts General Hospital (MGH). The firm is expanding these understandings by way of a significantly bigger study carried out by the Global Alzheimer’s Platform Foundation (GAP).

Bates mentioned the group at Linus Health is devoted to the trigger and feels a lot of duty to create and fantastic the speedy early detection of subtle modifications that can predict cognitive decline in men and women.

“When we go to these memory care facilities and we just know that each one of them has family,” Bates mentioned. “They’ve been through so much. They’re frustrated because they can’t even communicate sometimes anymore. And we really feel like we have an opportunity to help, and that’s what we’re we’re intently focused on.”

Linus utilizes multimodal digital tools made to be simply scalable and accessible, lowering the price of care considerably though detecting symptoms earlier than regular testing and at the most perfect time for an intervention. Early detection is the initial step in addressing cognitive decline, and Linus Health is supplying the foundation to provide screening and specialist insights into major care globally.

Pascual-Leone mentioned in a statement that Linus has aggressive ambitions in the next 3 years to address the threat that dementia poses to the aging population, and today’s funding news is an essential piece to accelerating the timeline.

Insurance has begun to cover these tests. Bates mentioned it could take a couple of years or more to scale up tests to the millions. The challenge is big. Anywhere from 3 million to 5 million men and women in the U.S. have Alzheimer’s, and quite a few millions more have dementia, such as my mother. COVID-19 has also taken a toll on the brain well being of quite a few men and women.

“You can’t mess around with human health. You need to be precise, and you have to show that, and I think we have shown that,” Bates mentioned. “There will be increasingly rapid adoption across these different verticals. We’re very much in research in pharma. But we’re increasingly moving into senior care and clinical care.”
