Brain cell ion balance and swelling after sudden brain injury

Official title: Neuronal Ion and Volume Shifts After Acute Brain Injury

Funded at Massachusetts General Hospital · NIH-11324023 · Data updated 2026-11-12

They are looking at how changes in ion levels and cell size after a sudden brain injury cause swelling or shrinkage for people with acquired brain injuries, including newborns.

Who could benefit from this research

Could help

People with recent acquired brain injuries — including adults with traumatic or stroke-related brain swelling and parents of very low birthweight or newborn infants with brain injury or seizures — would be most relevant to this research.

Less likely to help

People without brain injuries, those with chronic stable neurological conditions unrelated to acute ion/volume problems, or individuals unable to access the study site are unlikely to receive direct benefit.

What this research studies

This work focuses on how neurons control ions (especially chloride) and cell volume after an acute brain injury, and how that control affects GABA signaling and seizures. The team studies the physical effects of charged macromolecules (Donnan effects) that change chloride and water movement inside and outside neurons. They explain why mature brains tend to swell (cytotoxic edema) while immature brains may shrink, and how those changes can cause MRI differences, tissue stretch, and bleeding in very low birthweight infants. The program builds on prior lab-to-clinic work and combines laboratory experiments, analysis of imaging and tissue effects, and steps toward clinical applications at Massachusetts General Hospital.

Why it matters

Potential benefit: If successful, this could lead to new ways to prevent or treat brain swelling in adults and reduce tissue injury and bleeding in premature infants.

How similar studies have gone: The lead investigator has already moved a therapy based on anion homeostasis into clinical use for neonatal seizures, so related approaches have shown clinical promise.
