We haven't solved why some children develop severe allergic asthma while others with similar exposure don't.
open
Global / Unspecified, Global
Childhood asthma rates have risen substantially, but why some children develop severe, persistent symptoms while others exposed to similar triggers don't remains only partly understood. A clearer answer could improve both prevention and treatment.

We can't yet fully treat chronic Lyme disease symptoms that persist after standard antibiotic treatment.
open
Global / Unspecified, Global
Some patients continue experiencing symptoms long after completing standard treatment for Lyme disease, and doctors disagree on both the cause and the best way to treat this lingering illness. Resolving this uncertainty remains a significant unmet need.

We don't have an effective way to prevent the recurrence of depression after a first episode.
open
Global / Unspecified, Global
Many people who experience one episode of depression go on to experience another, and current treatments don't reliably prevent this recurrence. Better long-term prevention strategies remain an important gap in mental health care.

We haven't found a reliable way to detect early-stage stomach cancer before it becomes advanced.
open
Global / Unspecified, Global
Stomach cancer often causes no clear symptoms until it has progressed significantly, particularly in regions without routine screening programs. Earlier, more accessible detection could substantially improve survival outcomes.

We can't yet fully prevent the birth defects caused by certain infections during pregnancy.
open
Global / Unspecified, Global
Infections like Zika or cytomegalovirus can cause serious birth defects if contracted during pregnancy, and prevention options remain limited in many regions. Better vaccines or protective treatments remain needed to close this gap.
Citation ID: WS00530

We don't have an effective way to reverse the cartilage loss that causes osteoarthritis.
open
Global / Unspecified, Global
Osteoarthritis treatment currently focuses on managing pain and preserving remaining function rather than restoring lost cartilage. A regenerative treatment could transform care for one of the most common causes of chronic pain in older adults.
Citation ID: WS00529
Title: We don't have an effective way to reverse the cartilage loss that causes osteoarthritis.

We haven't solved how to make organ transplants available to more patients without relying solely on donor scarcity.
open
Global / Unspecified, Global
Thousands of patients remain on transplant waiting lists that never resolve in time, largely because donor organ supply can't keep pace with demand. Alternatives like lab-grown organs remain the most promising but still unrealized solution.

Title: We haven't solved how to make organ transplants available to more patients without relying solely on donor scarcity.

We can't yet fully explain why chronic fatigue sometimes follows viral infections long after the virus is gone.
open
Global / Unspecified, Global
Post-viral fatigue syndromes, including long COVID, leave some patients exhausted for months or years after the initial infection has cleared, and the biological mechanism remains unclear. Understanding this could unlock treatment for a currently poorly understood condition.

We don't have a reliable way to prevent the joint damage caused by gout attacks over time.
open
Global / Unspecified, Global
Repeated gout attacks can cause lasting joint damage even with treatment, and prevention still relies mainly on managing uric acid levels rather than fully eliminating the underlying risk. A more definitive prevention method remains unmet.
Citation ID: WS00526
Title: We don't have a reliable way to prevent the joint damage caused by gout attacks over time.

We haven't found a way to cure narcolepsy, only manage its symptoms with medication.
open
Global / Unspecified, Global
Narcolepsy causes sudden, uncontrollable sleep episodes that significantly disrupt daily life, and current treatments manage symptoms rather than address the underlying cause. A true cure remains undiscovered.

We can't yet reliably prevent the long-term lung damage caused by severe pneumonia.
open
Global / Unspecified, Global
Even after recovering from severe pneumonia, some patients experience lasting reductions in lung function that current treatments don't fully reverse. Preventing this lasting damage remains an unmet medical goal.

We don't have an affordable cure for leishmaniasis available in all the regions where it's endemic.
open
Global / Unspecified, Global
This parasitic disease affects millions in tropical and subtropical regions, but effective treatment remains expensive, difficult to access, or logistically challenging for many affected communities. Closing this access gap remains unresolved.

We haven't solved how to treat postpartum psychosis quickly enough to prevent serious harm.
open
Global / Unspecified, Global
This rare but severe condition can develop rapidly after childbirth, and delays in recognition and treatment can have dangerous consequences for both mother and baby. Faster, more reliable detection and treatment protocols remain an urgent unmet need.

We can't yet fully prevent the vision loss caused by diabetic retinopathy in all diabetic patients.
open
Global / Unspecified, Global
Diabetic retinopathy remains a leading cause of blindness among working-age adults, and while treatment can slow progression, prevention before damage begins remains incomplete. Earlier, more effective prevention could protect vision for millions of diabetics.
