Nashville Brain Institute (NBI) is a Neuropsychiatric clinical and research institution that specializes in precision psychiatric diagnosis and treatment. Precision psychiatry is an approach that focuses on understanding the underlying neurobiological mechanisms that cause the symptoms of mental health conditions. Our goal is to develop personally tailored, measurement-based evaluations and interventions by targeting the underlying mechanisms, which in turn will address previously overlooked aspects of mental health conditions and offer a long term solution for mental illness. In NBI, our mental health specialists work together with our neurologist to bridge the gap between neurobiology and psychiatry, therefore we can resolve complicated neuropsychiatric conditions through comprehensive diagnostic approaches and treatment modalities, including neurotransmitter assessment, neuropsychological tests, Ketamine treatment, Ketamine-assisted psychotherapy, TMS Treatment, Suboxone treatment, IOP group therapy.
