Diagnosing autoimmune encephalitis in psychiatry: clinical recommendations and unresolved challenges from the GENERATE network

Psychiatric syndromes can be caused by underlying autoimmune encephalitis (AE). This represents a diagnostic challenge at the interface of psychiatry and neurology. While AE mostly manifests with a combined, complex neuropsychiatric syndrome, some patients with AE may (initially)...

Accelerated TMS is associated with changes of subgenual cingulate–default mode network coupling in depression: an observational 7 Tesla fMRI study

Abstract Background Accelerated transcranial magnetic stimulation (aTMS) is an effective treatment for depression, but its neurobiological mechanisms of action remain to be elucidated. This study used high-resolution 7-Tesla MRI to investigate changes in resting-state functional...

Clinical and neurobiological correlates of tardive dyskinesia in schizophrenia spectrum disorders and mood disorders

Abstract Tardive dyskinesia (TD) is a persistent sensorimotor syndrome associated with antipsychotic exposure in schizophrenia spectrum disorders (SSD) and mood disorders (MOD), yet its neurobiological basis remains poorly understood. We investigated whether TD represents a disti...

Examining smartphone-assessed executive function metrics and intrinsic resting-state functional connectivity in depression

<title>Abstract</title> Major Depressive Disorder (MDD) is a common and costly mental health condition that is often associated with deficits in executive function. Smartphone applications (“apps”) have emerged as promising methods for assessing mental health-related outcomes in...

Frequency of therapeutic drug monitoring in inpatient precision depression care and duration of hospitalization

Abstract In psychiatry, therapeutic drug monitoring (TDM) is routinely used to improve treatment safety and efficacy, yet its association with hospitalization duration and cost-effectiveness remains unclear. We hypothesized that the frequency of routinely requested TDM is associa...
