    Health and Cognition among Adults with and without Traumatic Brain Injury: A Matched Case-Control Study
    (Taylor & Francis, 2022) Kumar, Raj G.; Ketchum, Jessica M.; Hammond, Flora M.; Novack, Thomas A.; O’Neil-Pirozzi, Therese M.; Silva, Marc A.; Dams-O’Connor, Kristen; Physical Medicine and Rehabilitation, School of Medicine
    Objectives: To evaluate associations between traumatic brain injury (TBI) and presence of health conditions, and to compare associations of health and cognition between TBI cases and controls. Methods: This matched case-control study used data from the TBI Model Systems National Database (TBI cases) and Midlife in the United States II and Refresher studies (controls). 248 TBI cases were age-, sex-, race-, and education-matched without replacement to three controls. Cases and controls were compared on prevalence of 18 self-reported conditions, self-rated health, composite scores from the Brief Test of Adult Cognition by Telephone. Results: The following conditions were significantly more prevalent among TBI cases versus controls: anxiety/depression (OR = 3.12, 95% CI: 2.20, 4.43, p < .001), chronic sleeping problems (OR = 2.76, 95% CI: 1.86, 4.10, p < .001), headache/migraine (OR = 2.61, 95% CI: 1.50, 4.54, p = .0007), and stroke (OR = 6.42, 95% CI: 2.93, 14.10, p < .001). The relationship between self-rated health and cognition significantly varied by TBI (pinteraction = 0.002). Conclusion: Individuals with TBI have greater odds of selected neurobehavioral conditions compared to their demographically similar uninjured peers. Among persons with TBI there was a stronger association between poorer self-rated health and cognition than controls. TBI is increasingly conceptualized as a chronic disease; current findings suggest post-TBI health management requires cognitive supports.

    Patterns of Functional Change Five to Ten Years after Moderate-Severe Traumatic Brain Injury
    (Mary Ann Liebert, Inc., 2021) Hammond, Flora M.; Malec, James F.; Corrigan, John D.; Whiteneck, Gale G.; Hart, Tessa; Dams-O’Connor, Kristen; Novack, Thomas A.; Bogner, Jennifer; Dahdah, Marie N.; Eagye, C.B.; Sevigny, Mitch; Ketchum, Jessica M.; Physical Medicine and Rehabilitation, School of Medicine
    This study aims to characterize the patterns of functional change experienced between 5 and 10 years after moderate-severe traumatic brain injury (TBI). The study included TBI Model Systems national database participants (N = 372) at six sites who experienced TBI, received inpatient rehabilitation, and were followed at 5 and 10 years post-TBI. Outcome measures included self- or proxy-reported Functional Independence Measure (FIMTM) structured interview at 5 and 10 years post-TBI and domain change indices (DCIs) at 10 years to assess subjective change over the previous 5 years. When all seven FIM and subjective DCI subscales were considered together, 69% reported improvement in at least one subscale and 41% reported decline in at least one subscale; 51% reported more domains improved than declined, and 20% reported more domains declined than improved. Age at injury, post-traumatic amnesia duration, FIM, and depression and anxiety at year 5 were associated with FIM change and DCI measures. Although most persons with moderate-severe TBI do not experience widespread change from year 5 to 10 on individual FIM subscales or perceived domain-specific subscales, the vast majority do report change in one or more domains, with more improvement than decline and more change in subjective DCI than in FIM. Clinicians and researchers should be alert to the possibility of both positive and deleterious changes many years after TBI.

    Prevalence of Medical and Psychiatric Comorbidities Following Traumatic Brain Injury
    (Wolters Kluwer, 2019-08-01) Hammond, Flora M.; Corrigan, John D.; Ketchum, Jessica M.; Malec, James F.; Dams-O'Connor, Kristen; Hart, Tessa; Novack, Thomas A.; Bogner, Jennifer; Dahdah, Marie N.; Whiteneck, Gale G.; Physical Medicine and Rehabilitation, School of Medicine
    Objective: To examine the prevalence of selected medical and psychiatric comorbidities that existed prior to, or up to 10 years following, traumatic brain injury (TBI) requiring acute rehabilitation. Design: Retrospective cohort. Setting: Six TBI Model Systems centers. Participants: 404 participants in the TBI Model System National Database who experienced TBI 10 years prior. Interventions: Not applicable. Main Outcome Measure: Self-reported medical and psychiatric comorbidities and the onset time of each endorsed comorbidity. Results: At 10 years post-injury, the most common comorbidities developing post-injury, in order, were: back pain, depression, hypertension, anxiety, fractures, high blood cholesterol, sleep disorders, panic attacks, osteoarthritis, and diabetes. Comparing those 50 years and older to those less than 50 years, diabetes (OR = 3.54; p = 0.0016), high blood cholesterol (OR = 2.04; p = 0.0092), osteoarthritis (OR = 2.02; p = 0.0454), and hypertension (OR = 1.84; p = 0.0175) were significantly more prevalent in the older cohort while panic attacks (OR = 0.33; p = 0.0022) were significantly more prevalent in the younger cohort. No significant differences in prevalence rates between the older and younger cohorts were found for back pain, depression, anxiety, fractures, or sleep disorders. Conclusions: People with moderate-severe TBI experience other medical and mental health comorbidities during the long-term course of recovery and life after injury. The findings can inform further investigation into comorbidities associated with TBI and the role of medical care, surveillance, prevention, lifestyle, and healthy behaviors in potentially modifying their presence and/or prevalence over the life span.
