A brief summary of current research.
Smania, N, Avesani, R, Roncari, L, Ianes, P, Girardi, P, Varalta, V, Gambini, MG, Fiaschi, A, and Gandolfi, M. Journal of Head Trauma Rehabilitation: Vol. 28 (2), pp 131–140.
These Italian researchers studied people with severe traumatic brain injury, cerebrovascular brain injury, and anoxic brain injury. People with TBI achieved greater functional and cognitive improvements than those with cerebrovascular brain injury or anoxic brain injury. Patients with TBI also had a greater chance of returning home than individuals with other kinds of brain injuries.
Age, gender, cause of injury, and the disability rating score at the time of hospital admission also contributed to predicting when people would be discharged and to where — home or a long-term facility.
