Dr. Amy Byers’ research is predominately focused on suicide prevention in older Veterans. This work is highly relevant to and has very high impact on Veterans and VA healthcare. Veterans 50 years and older have the highest number of lives lost to suicide and make up the majority (> 70%) of the Veteran population. Older adults and, in particular, older Veterans accumulate a significant amount of life experiences, including suffering multiple comorbidities, losses, and traumas, that impact their mental and physical well-being. Even further adding to the complexity, mental health care often occurs in non-mental health settings under the influence of personal and society notions and stigmas about mental illness and about aging. Dr. Byers’ Lab is uniquely positioned to conduct research at this level of complexity. Dr. Byers has developed a deep, clinically relevant understanding of the nature of mental health in late life, its course, treatment and impact. Her research covers multiple sub-areas of late-life mental health, i.e., late-life suicide, late-life posttraumatic stress disorder, mental health services use with age, geriatric depression, and gerontological biostatistics. In particular, understanding suicide-related outcomes in older adults/Veterans requires substantially different conceptual and methodologic considerations, which Dr. Byers and her team are uniquely qualified to undertake. There are 4 over-arching research areas and Aims that Dr. Byers will actively pursue during the proposed Research Career Scientist Award period: 1) To characterize and identify patterns of health services use and diagnostic profiles at a national level among older adults/Veterans who have experienced late-life suicide or mental health disorders; 2) To identify predictors of late-life suicide; 3) To advance late-life suicide and mental health research in prominent health disparity and vulnerable groups; and 4) To advance suicide and neuropsychiatric research in Veterans incarcerated and returning to community in later life. In summary, the first 3 Aims are supported by an on-going VA CSR&D Merit Award (I01 CX001119; PI: Byers). Aim 2 and 3 are further supported by a Genius Award (PI: Byes) from the UCSF Older Americans Independence Center (NIA-funded Pepper Center). Aim 4 is supported by a NIMH Multi-PI R01 grant in collaboration with Dr. Lisa Barry from University of Connecticut (MH117604; Multi-PI: Byers/Barry). Additionally, Dr. Byers and Dr. Barry were recently awarded a NIMH/NIA Supplement to the parent grant to determine the burden of Alzheimer’s disease and related diseases in older adults/Veterans with a recent history of incarceration. There are many seminal contributions by Dr. Byers’ Lab in terms of highly cited papers in high impact journals in support of these on-going activities. To name a few, she was the first to determine the high occurrence of late-life mood and anxiety disorders at a national level, first to determine and characterize nationa...
