Personalized Medicine

Background: The current coronavirus disease 2019 (COVID-19) pandemic has put an enormous stress on the mental health of frontline health care workers. Objective: Psychiatry departments in medical centers need to develop support systems to help our colleagues cope with this stress.
Trillions of microbes cover the surfaces of our bodies and inhabit our gastrointestinal tract. In the past decade, research efforts examining the role of the microbiome in mental health have moved to the forefront of neuroscience and psychiatry. Based on a foundation of animal studies demonstrating the vital role for microbiota-brain communication in brain development, behavior, and brain function over the life span, clinical studies have started to consider the microbiome in psychiatric disorders.
Traumatic brain injury (TBI) is one the most common human afflictions, contributing to long-term disability in survivors. Emerging data indicate that functional improvement or deterioration can occur years after TBI. In this regard, TBI is recognized as risk factor for late-life neurodegenerative disorders. TBI encompasses a heterogeneous disease process in which diverse injury subtypes and multiple molecular mechanisms overlap.
Perinatal depression (PND) is a heterogeneous disorder with differences in timing of onset of depression, which influences symptomology, severity, and treatment efficacy. Researchers must embrace the heterogeneity to bring fruition to a precision medicine approach for women in reproductive mental health care. Galea and Frokjaer discuss the heterogeneity of perinatal depression based on timing onset, which influences symptoms and has implications for etiology and treatment efficacy. The clinical and research community can exploit this heterogeneity to uncover precision treatment strategies.
