Traumatic Brain Injury and Stroke

TBI and stroke are among the leading causes of acute and chronic disability in this country. TBI occurs in more than 500,000 individuals in the United States every year and may result from such causes as motor vehicle accidents, falls, bicycle accidents, and other traumatic injuries.

Stroke is among the leading causes of death in the United States for women and men, with an incidence of just more than 500,000 individuals each year. Stroke accounts for nearly one-half of all those hospitalized for acute neurological conditions annually. Although the majority of individuals who sustain a stroke survive, a significant proportion of survivors require rehabilitation, and nearly one-third have some type of permanent disability. Among those who survive stroke, 50 percent are alive more than five years after the event, which means that rehabilitation needs continue well after the initial event. The rehabilitation needs and goals of individuals with stroke vary considerably. For some, the goal may be to return to full independence and resumption of all previous life activities. For others, the goal may be to return home with family assistance.

This program supports research to understand all aspects of TBI and stroke, including their underlying mechanisms, and to develop and assess medical rehabilitation therapies and interventions related to improving function, quality-of-life, and outcomes for stroke and TBI patients. In addition, the program supports efforts related to secondary conditions of TBI and stroke, such as muscle atrophy, speech and language problems, pain, and psychological and psychosocial effects of these conditions.

Stroke: Estimated Number of Incidences - U.S. - Annually

The 1996 results were compared to those of 1995 [8] (in parentheses). The NIS database contained 384,968 (377,544) patient discharges with a principal or secondary (first code reported) diagnosis of cerebrovascular disease. This was extrapolated to 2,082,005 (1,977,794) patient discharges in the United States. Table ‚ÄčTable11 uses the ICD-9 code-specific pooled PPVs [8] to adjust for false positives and reports that there were 712,000 (682,000) hospital strokes in the United States, with a 95% confidence interval of 688,000 (660,000) to 737,000 (704,000). We believe that at least 71,000 (68,000) additional strokes were nonhospital strokes, 10% of the total occurrences of stroke. We thus estimate that there were over 783,000 (750,000) incident and recurrent strokes in the United States in 1996 (1995). The sensitivity analysis on the nonhospital stroke rate produced a range from 748,000 (716,000) to 819,000 (784,000).
