This week, lets get into some of the more cutting edge treatments out there for our neurological ailments. We have a great startup spotlight featuring a great company beginning phase-3 trials. Investments in neurotech have also picked up in recent weeks, so I’m really excited to get back into the swing of research. Enjoy, and thanks for stopping by!

Introduction

When Robert, a 65-year-old former engineer, was diagnosed with early-stage Alzheimer’s in 2023, his family feared the worst. Traditional medications offered little hope of slowing his cognitive decline. Yet today, Robert participates in a clinical trial using a simple light-and-sound therapy headset for one hour daily. After six months, not only has his cognitive decline slowed dramatically, but his family reports moments of the “old Robert” returning. His story represents a glimpse into the future for the billion-plus people worldwide affected by neurological disorders – conditions that cost our global economy over $800 billion annually.

Traditional pharmaceutical approaches to neurological conditions have hit roadblock after roadblock, with CNS drug development facing failure rates exceeding 95%. This staggering inefficiency has created an urgent need for novel neurotechnologies that don’t just manage symptoms but potentially modify disease progression. The innovations below represent what’s possible when we think beyond pills.

Why Neurotechnology’s Moment Is Now (2025)

The global neurotechnology market is experiencing unprecedented growth, projected to reach $19.3 billion by 2026 at a compound annual growth rate of 13.5%. This surge isn’t happening in a vacuum. Recent FDA approvals for novel devices, expanded Medicare coverage decisions, and increased investor confidence have created a perfect storm for accelerated commercialization and adoption of these technologies.

Behind this market inflection point lies a powerful technological convergence. Advances in artificial intelligence for signal processing, miniaturization of electronics, improved battery technologies, and deeper understanding of neural circuits have collectively enabled breakthrough devices that seemed like science fiction just five years ago. The neurotechnology revolution isn’t coming – it’s already here.

Stem Cell Innovations: Cell-Free Therapies

What Are EVs and Why They Matter

Imagine tiny “messenger packages” released by stem cells – microscopic bubbles containing healing proteins, RNA, and other therapeutic molecules. These extracellular vesicles (EVs) deliver precise repair instructions to damaged brain tissue without the risks and complications of whole-cell transplants. Unlike entire stem cells, EVs can’t form tumors, trigger immune rejection, or persist inappropriately in tissue, making them potentially safer while conveying many benefits.

The global EV therapeutics market is poised for explosive growth and is expected to reach $2.2 billion by 2030. CNS applications represent the fastest-growing segment at an 18% CAGR. This remarkable expansion reflects technological improvements in EV production/purification and mounting evidence of efficacy across neurological conditions, from stroke to traumatic brain injury.

Clinical Applications & Investment Case

The clinical data supporting EVs is increasingly compelling. Recent studies demonstrate up to 45% improvement in blood-brain barrier function post-stroke and 33% reduction in inflammation markers in traumatic brain injury models. Perhaps most exciting is their potential in autoimmune conditions like multiple sclerosis, where they modulate immune responses without the broad immunosuppression of current therapies.

From a regulatory perspective, several EV therapeutics have received FDA Fast Track designation, with first approvals possibly arriving by 2027. Key players in this space include Capricor Therapeutics and Evox Therapeutics, both of which have attracted significant venture funding in recent rounds. For investors, the appeal lies in the scalability of EV production compared to cell therapies, potentially offering better manufacturing economics while addressing similar conditions.

Wearable Neurostimulation Revolution

Cala Health’s TAPS Therapy

Imagine a sleek, watch-like device that acts like a “pacemaker for tremors.” This is the elegant solution Cala Health has developed with its Transcutaneous Afferent Patterned Stimulation (TAPS) technology. The wrist-worn device first reads the unique tremor pattern in each patient, then delivers personalized electrical pulses designed to interrupt the specific neural circuits causing the shaking. For patients with essential tremor or Parkinson’s disease, the impact can be life-changing – from the regained ability to eat without spilling to writing legibly again.

The market implications are substantial following Medicare’s 2024 coverage approval decision, which expanded Cala’s addressable market to over 7 million Americans with essential tremors. At approximately $3,500 per device plus subscription services, and with clinical data showing an approximately 50% reduction in tremor in most patients, Cala has positioned itself at the sweet spot of clinical efficacy and economic value.

Investment Highlights & Competitive Landscape

Cala Health’s recent $50 million funding round, led by Longitude Capital, has fueled its expansion beyond essential tremor into Parkinson’s disease treatment, with projected revenues reaching $300 million by 2027. The company’s growth trajectory reflects broader investor confidence in wearable medical devices with demonstrated efficacy and reimbursement pathways.

When compared to alternatives, Cala’s competitive advantage becomes clear. Surgical options like Deep Brain Stimulation cost upwards of $50,000 and carry significant surgical risks, while medications for tremors typically offer only 25-40% efficacy and often come with troublesome side effects. Cala’s non-invasive, insurance-covered solution with minimal side effects presents a compelling value proposition for patients and payers, explaining its rapid market penetration since FDA clearance.

Next-Generation Neuromodulation

Light & Sound Therapies: Beyond Traditional Stimulation

The most exciting frontier in neuromodulation moves beyond electrical stimulation to leverage the precision of light and sound. Breakthroughs in optogenetics—using light-sensitive proteins to control specific neurons—and noninvasive gamma stimulation are enabling unprecedented control over neural circuits without invasive procedures or systemic medications.

The scientific evidence supporting these approaches continues to strengthen. A landmark 2024 study published in Nature demonstrated a remarkable 32% improvement in memory retention in Alzheimer’s models using targeted light stimulation of hippocampal circuits—far exceeding results from existing medications. Meanwhile, noninvasive 40Hz sensory stimulation has shown the ability to reduce amyloid buildup and enhance cognitive function across multiple animal models and early human studies.

Deep Brain Stimulation: Precision Targeting

Traditional Deep Brain Stimulation (DBS) has evolved dramatically from its first-generation implementations. Modern systems now offer directional stimulation capabilities and closed-loop feedback, allowing for precise targeting of specific brain circuits while minimizing off-target effects. This evolution dramatically increases efficacy while reducing side effects compared to earlier DBS devices.

The global DBS market reflects this technological maturation, projected to reach $2.2 billion by 2028. While movement disorders like Parkinson’s disease remain the primary indication, new applications beyond movement disorders – including treatment-resistant depression, obsessive-compulsive disorder, and, most recently, Alzheimer’s disease – represent the most significant growth opportunities. Early trials stimulating the fornix region in Alzheimer’s patients have shown promising results in slowing cognitive decline, opening an entirely new market for DBS technologies.

Startup Spotlight: Cognito Therapeutics

The Gamma Stimulation Breakthrough

Cognito Therapeutics has developed perhaps the most user-friendly approach to treating Alzheimer’s disease: patients wear a headset for one hour daily that delivers precisely calibrated 40Hz light and sound stimulation. This seemingly simple intervention synchronizes brain waves at the gamma frequency (40Hz), which research shows can reduce Alzheimer’s pathology and improve neural function. The results have been striking—clinical trials demonstrate a 76% slower decline than standard care, with significant preservation of brain volume in key regions affected by Alzheimer’s.

Founded by MIT scientists following their breakthrough research on gamma oscillations, Cognito has translated academic discoveries into a practical therapy with remarkable speed. Their Spectris™ device has received FDA Breakthrough Device designation and successfully completed Phase 2 trials, with Phase 3 studies underway. What distinguishes their approach is its non-invasiveness, lack of significant side effects, and potential for home use without medical supervision.

Investment Case & Future Outlook

Cognito recently secured a $73 million Series B funding round led by Morningside Ventures at a reported $300 million valuation—impressive for a pre-approval medical device company. The investment thesis is compelling: With 5.8 million Alzheimer’s patients in the US alone and a projected annual cost of approximately $12,000 per patient, the addressable market exceeds $70 billion. Even capturing a modest percentage of this market would represent a significant return on investment.

Looking ahead, Cognito isn’t limiting itself to Alzheimer’s disease. The company is actively exploring applications of its gamma stimulation platform in Parkinson’s disease, autism spectrum disorders, and other neurological conditions characterized by neural synchronization abnormalities. This expansion strategy could triple their addressable market by 2030, offering investors multiple shots on goal from a single technology platform.
