Neonatal encephalopathy from birth asphyxia is not curable, but it is treatable. Therapeutic hypothermia is a disease-modifying therapy that slows the progression of brain injury and reduces death and major disability. It does not reverse damage already done Mend. Access to this treatment varies around the world, so not every baby can receive it. In high-resource settings, deaths and severe disability have been falling steadily over the past decades, though global progress is uneven. The single most important milestone remains the introduction of therapeutic hypothermia. Research continues with 28 trials started in the last five years, 26 still active, seeking better ways to protect the newborn brain.

What does therapeutic hypothermia do?

It lowers the baby's body temperature for about 72 hours. This slows down the secondary injury process in the brain, reducing the chances of death or severe disability.

How soon after birth must cooling start?

Ideally within six hours of birth. Early initiation is linked to better outcomes. After that window, the protective effect diminishes.

Does cooling reverse brain damage that has already happened?

No. It cannot repair established injury. It works by limiting further damage, giving the brain a better chance to recover on its own.

Why isn't cooling available everywhere?

It requires intensive care settings with trained staff, monitoring equipment, and consistent protocols. In many low-resource regions, these resources are lacking.

What are researchers working on now?

Over two dozen recent trials are exploring additional neuroprotective drugs, better cooling techniques, and ways to identify which infants benefit most. Some are in final testing phases.
