The ventral tegmental area (VTA), nucleus accumbens (NAcc), and prefrontal cortex (PFC) are essential for experiencing pleasure and initiating motivated behaviour. The VTA, NAcc, and PFC are connected through the medial forebrain bundle (MFB). In hum

Reduced corticolimbic habituation to negative stimuli characterizes bipolar depressed suicide attempters

Suicide attempts in Bipolar Disorder are characterized by high levels of lethality and impulsivity. Reduced rates of amygdala and cortico-limbic habituation can identify a fMRI phenotype of suicidality in the disorder related to internal over-arousin

Psychopharmacological treatment is not associated with reduced suicide ideation and reattempts in an observational follow-up study of suicide attempters. Journal of psychiatric research, 140, pp. 180-186. Elsevier 10.1016/j.jpsychires.2021.05.068

Background Disorders of mental health are major risk factors for suicidal behavior and require adequate treatment. However, the effect of psychotropic medication on suicidal behavior is unclear. Methods The 120 participants in a randomized clinical t
