Sale P, Zampolini M, Juocevicius A, Lains JM, Giustini A, Negrini S, Franceschini M: The Role of the European Physiatrist in Traumatic Brain Injury. Am J Phys Med Rehabil 2011;90:83Y86.The purpose of this commentary was to show the role of the physiatrist and the organization of the rehabilitation of patients with traumatic brain injury (TBI) in Europe. TBI is a heterogeneous condition that encompasses a broad spectrum of disorders and remains one of the most difficult and challenging problems facing many clinicians, particularly neurosurgeons, physiatrists, and critical care specialists. The World Health Organization publishes an International Classification of Diseases, where trauma and head injury are included in the chapter ''Injury and poisoning.'' 1 A TBI from a road accident, fall, or sportsrelated incident can lead to a variety of sensorimotor, behavioral, and cognitive impairments, depending on the areas of the brain that are injured. The last 20 yrs has seen major advances in the prevention and treatment of head injury, resulting in a substantial decrease in mortality. An estimated 1.5 million Americans sustain a TBI each year, which is 8 times the number of people diagnosed with breast cancer and 34 times the number of new cases of HIV or AIDS, according to the Centers for Disease Control and Prevention. 2 TBI is also a major public health problem in Europe, with an estimated annual incidence of up to 500 per 100,000 population and more than 200 hospital admissions per 100,000 admissions each year. 3 The long-term disabilities can be severe, and specific difficulties are experienced in social functions and family lives. 4Y6 Most of the literature on mild TBI has been based on patients treated in single national clinics or hospitals. 7 A review by Tagliaferri et al. 3 showed how difficult it was to reach a consensus on all epidemiologic findings across 23 published European studies because of critical differences in methods used across the reports. He highly recommended the development of research guidelines to standardize definitions, case finding, and data reporting parameters to help establish a more precise description and enhance the utility of the studies on the epidemiology of TBI in Europe. 3 The review identified 23 reports with data on epidemiologic parameters of TBI in the published literature. Six reports were of
