A significant share of patients with depression don't respond adequately to standard treatments, and doctors currently have limited ability to predict who will respond to which approach. Better personalized treatment matching remains an open challenge.

Glaucoma often causes irreversible vision loss before it's diagnosed, since early stages typically have no noticeable symptoms. Better early detection and prevention methods remain a pressing unmet need in eye care.

Chronic sinus inflammation affects a large number of people and current treatments, from medication to surgery, often only partially resolve symptoms long-term. A more definitive treatment remains undeveloped.

Effective treatments for hepatitis B exist, but cost and access remain out of reach for many of the hundreds of millions of people living with the infection globally, particularly in lower-income regions. Closing this access gap remains unresolved.

The same virus or bacteria can cause mild illness in most people while triggering severe, sometimes life-threatening complications in others, and we still don't fully understand why. This gap makes predicting and preventing severe outcomes difficult.

Current treatments for multiple sclerosis can reduce the frequency and severity of flare-ups but can't stop or reverse the underlying immune attack on the nervous system. A true cure remains an unmet goal after decades of research.

By the time visible symptoms of Parkinson's appear, significant neurological damage has usually already occurred, limiting how much treatment can help. Detecting the disease years earlier could open the door to more effective intervention.

Age-related muscle loss, known as sarcopenia, contributes to frailty and falls in older adults, and current treatments rely mainly on exercise and diet rather than addressing the underlying biological decline. A more direct medical solution remains undeveloped.

Chronic skin conditions often require lifelong management with creams and medications rather than a resolution of the underlying immune or genetic causes. A real cure, rather than continuous symptom control, remains unavailable.

Existing treatments for hair loss can slow the process for some people but rarely reverse it completely, and the underlying biology of hair follicle loss isn't fully understood. A true prevention or reversal method remains undiscovered.

Fertility treatments like IVF help many people conceive, but success rates still drop significantly with age due to biological factors that current medicine can't fully reverse. Understanding and addressing this decline remains incomplete.

Kidney disease often advances silently for years before symptoms appear, and by the time it's caught, treatment options are limited mainly to slowing further decline. Catching and reversing it earlier remains an open medical challenge.

Bone density loss often goes unnoticed until a fall causes a serious fracture, by which point significant damage has already occurred. Better early detection and prevention could avoid many of these life-altering injuries.

Drug-resistant tuberculosis requires longer, more expensive, and more toxic treatment regimens that many patients in affected regions simply can't access or complete. This keeps a preventable disease deadly in the parts of the world least equipped to fight it.

Severe bleeding after childbirth remains one of the leading causes of maternal death worldwide, disproportionately in regions lacking access to blood transfusions and advanced medical care. Affordable, effective solutions for these settings remain limited.

Patients sometimes continue to experience pain months or years after the original injury has healed, suggesting the nervous system itself has changed in ways doctors don't fully understand. Solving this could transform treatment for chronic pain conditions.

Lung cancer screening guidelines are generally built around smoking history, but a meaningful share of cases occur in people who never smoked at all and often go undetected until later stages. Better screening approaches for this group remain underdeveloped.

IBS causes chronic digestive discomfort for a significant portion of people worldwide, yet treatment options remain limited to symptom management rather than addressing root causes. The underlying biology is still not fully mapped out.

Preeclampsia can develop suddenly and seriously endanger both mother and baby, and current screening still misses many cases until symptoms are already severe. Earlier, more accurate prediction could prevent serious harm.

Despite strict hygiene protocols, patients still frequently contract infections during hospital stays that they didn't have when they arrived. Closing this gap could save both lives and enormous healthcare costs.
