Objective: To investigate neurobehavioral symptoms in older adults with/without traumatic brain injury (TBI), other neurological conditions, and/or mental health issues. Design: Cross-sectional study. Setting: Community. Participants (or Animals, Specimens, Cadavers): English-speaking older adults (>65 years, n=309) with a self-reported history of TBI (n=18; n=13 without, n=5 with mental health history), other neurological conditions (n=18; n=10 without, n=5 with mental health history), mental health history only (n=29), and no neurological or mental health history (healthy controls; n=244). Interventions: Not applicable. Main Outcome Measure(s): Behavioral Assessment Screening Tool (BAST) subscales: Negative Affect, Substance Abuse, Executive Function, Fatigue, Impulsivity. Results: Older adults with only mental health history reported the highest negative affect (M=3.07, SD=0.63), followed by individuals with TBI and mental health history (M=2.88, SD=0.56) and other neurological conditions and mental health history (M=2.78, SD=0.53). Older adults with mental health history only reported the highest substance abuse (M = 1.62, SD = 1.02) and impulsivity (M=2.29, SD=0.75), followed by individuals who had other neurological conditions with mental health history (M=1.38, SD = 0.52) and older adults with TBI, regardless of metal health history, other neurological conditions only and healthy controls (M=1.10 -1.31, SD=0.32-0.44 and M=1.77-2.10, SD=0.47-0.82 respectively). Older adults with mental health history, regardless of neurological conditions, reported more symptoms of fatigue (M=3.06-3.30, SD=0.63-0.75) than those without mental health history (M=2.79-2.30, SD=0.37-0.65). Conclusions: Negative affect and fatigue were more severe in older adults with a history of mental health issues, regardless of the presence/absence of TBI or other neurological conditions, suggesting affect and fatigue are more related to mental health than neurological function.
