We can't yet fully prevent the long-term joint damage caused by rheumatoid arthritis.
open
Global / Unspecified, Global
Modern treatments can slow rheumatoid arthritis significantly, but many patients still experience some degree of joint damage over time despite treatment. Stopping this damage completely remains an unmet medical goal.
Citation ID: WS00494

We don't have a scalable, affordable treatment for hepatitis B available to everyone infected worldwide.
open
Global / Unspecified, Global
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.

We haven't solved why some people develop severe complications from common infections that most people recover from easily.
open
Global / Unspecified, Global
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.
Citation ID: WS00492
Title: We haven't solved why some people develop severe complications from common infections that most people recover from easily.

We can't yet cure multiple sclerosis, only slow its progression.
open
Global / Unspecified, Global
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.

Title: We can't yet cure multiple sclerosis, only slow its progression.

We don't have a reliable way to detect Parkinson's disease before physical symptoms like tremors appear.
open
Global / Unspecified, Global
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.

We haven't found a way to prevent the muscle loss that comes with aging.
open
Global / Unspecified, Global
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.
Citation ID: WS00489
Title: We haven't found a way to prevent the muscle loss that comes with aging.

We can't yet fully treat eczema and other chronic skin conditions without ongoing management.
open
Global / Unspecified, Global
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.
Citation ID: WS00488
Title: We can't yet fully treat eczema and other chronic skin conditions without ongoing management.

We don't have an effective way to prevent hair loss caused by genetic or hormonal factors.
open
Global / Unspecified, Global
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.
Citation ID: WS00487
Title: We don't have an effective way to prevent hair loss caused by genetic or hormonal factors.

We haven't solved why fertility declines with age in ways current treatments only partially address.
open
Global / Unspecified, Global
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.
Citation ID: WS00486
Title: We haven't solved why fertility declines with age in ways current treatments only partially address.

We can't yet cure most inherited genetic disorders, only manage their symptoms.
open
Global / Unspecified, Global
Conditions caused by a single faulty gene, from cystic fibrosis to muscular dystrophy, still mostly rely on symptom management rather than correcting the genetic cause itself. Gene therapy shows promise but remains far from a widely available cure.
Citation ID: WS00485
Title: We can't yet cure most inherited genetic disorders, only manage their symptoms.

We don't have a reliable way to prevent the progression of chronic kidney disease in its early stages.
open
Global / Unspecified, Global
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.

Title: We don't have a reliable way to prevent the progression of chronic kidney disease in its early stages.

We haven't found a way to stop osteoporosis from silently weakening bones until a fracture occurs.
open
Global / Unspecified, Global
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.

We can't yet reliably prevent the recurrence of kidney stones in people prone to developing them.
open
Global / Unspecified, Global
Kidney stones are painful and prone to recurring, yet prevention methods remain limited mostly to general dietary advice rather than addressing individual underlying causes. More targeted prevention could spare patients repeated painful episodes.

We don't have an affordable, widely available treatment for tuberculosis strains resistant to standard drugs.
open
Global / Unspecified, Global
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.
Citation ID: WS00481
Title: We don't have an affordable, widely available treatment for tuberculosis strains resistant to standard drugs.

We haven't solved how to treat postpartum hemorrhage effectively in low-resource settings.
open
Global / Unspecified, Global
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.

We can't yet fully explain why chronic pain sometimes persists long after an injury has physically healed.
open
Global / Unspecified, Global
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.

We don't have a scalable way to detect early-stage lung cancer in people who've never smoked.
open
Global / Unspecified, Global
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.

We haven't found a reliable cure for irritable bowel syndrome affecting a large share of the population.
open
Global / Unspecified, Global
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.

We can't yet accurately predict which pregnancies will develop dangerous complications like preeclampsia.
open
Global / Unspecified, Global
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.

We don't have a fully effective way to prevent hospital-acquired infections.
