Wales needs more services to deal with the growing number of people suffering disabilities caused by head traumas, a brain injuries expert says.
Prof Rodger Wood of Swansea University said rehabilitation units for patients after they leave hospital can save millions every year in care costs.
A charity is building a residential unit in Carmarthenshire but Prof Wood said another four were needed.
The Welsh government said it was working to improve services.
