Figure 2. Additive effects of TBI and other risk factors on dementia incidence.

Figure 2

The additive association between traumatic brain injury (TBI) and other dementia risk factors is illustrated by showing the cumulative incidence of dementia with age as the time scale for veterans with TBI only (blue), other risk factor only (orange), both risk factors (brown), or neither risk factor (green). Other risk factors examined include depression (A), posttraumatic stress disorder (PTSD) (B), and cerebrovascular disease (CVD) (C).
