We haven't solved how to prevent the long-term kidney damage caused by certain common pain medications.
open
Global / Unspecified, Global
Long-term use of some widely available pain medications can gradually damage kidney function, often without obvious symptoms until damage is significant. Better awareness and prevention methods remain incompletely applied.

We can't yet fully explain why chronic fatigue syndrome affects women more frequently than men.
open
Global / Unspecified, Global
Chronic fatigue syndrome is diagnosed in women considerably more often than men, and the biological or social reasons behind this imbalance remain only partly understood. A clearer answer could improve diagnosis and treatment for both sexes.

We don't have an effective, scalable way to treat childhood obesity before it leads to related diseases.
open
Global / Unspecified, Global
Many children with obesity go on to develop related health issues as adults, and current interventions haven't proven consistently effective at reversing childhood obesity at a population scale. A more effective, scalable approach remains an urgent unmet need.

We don't have an effective way to prevent the long-term lung effects of childhood asthma into adulthood.
open
Global / Unspecified, Global
Children with poorly controlled asthma can experience lasting reductions in lung function as adults, even if their symptoms improve over time. Preventing this long-term damage remains an incomplete area of pediatric respiratory care.

We haven't found a reliable way to detect early cognitive decline in adults before it becomes clinically obvious.
open
Global / Unspecified, Global
Subtle cognitive changes often precede a formal dementia diagnosis by years, but current screening tools aren't sensitive enough to reliably catch this earliest stage. Better early detection could open the door to earlier, more effective intervention.

We can't yet fully explain why some children outgrow food allergies while others carry them into adulthood.
open
Global / Unspecified, Global
Some childhood food allergies resolve naturally over time while others persist for life, and predicting which pattern a given child will follow remains largely uncertain. A clearer understanding could guide better long-term management.

We don't have an effective way to treat most cases of chronic idiopathic urticaria that resist standard therapy.
open
Global / Unspecified, Global
This form of chronic hives has no identifiable trigger and can resist standard antihistamine treatment in a subset of patients, leaving them with few further options. A more effective treatment approach remains undeveloped.

We don't have a scalable way to reduce maternal mortality in regions with limited access to emergency obstetric care.
open
Global / Unspecified, Global
Complications during childbirth can become fatal within minutes without access to emergency care, and many regions still lack the infrastructure to respond quickly enough. Closing this gap remains one of the most urgent unmet needs in global health.

We haven't found an effective, widely available way to treat chronic tinnitus caused by nerve damage.
open
Global / Unspecified, Global
Tinnitus caused by underlying nerve damage is particularly difficult to treat, and current options mostly focus on management strategies like sound therapy rather than addressing the nerve issue directly. A more direct treatment remains undeveloped.

We don't have a reliable way to detect testicular cancer early enough in populations without routine screening awareness.
open
Global / Unspecified, Global
Testicular cancer is highly treatable when caught early, but a lack of widespread screening awareness means some cases are diagnosed later than they should be. Improving early detection and awareness remains an underaddressed public health gap.
