Depression in patients with acute traumatic brain injury.
ABSTRACT This study was undertaken to examine patients with closed head injuries for the presence of depressive disorders.
A consecutive series of 66 patients with closed head injuries but no significant spinal cord or other organ system injury were examined by means of a semistructured psychiatric interview. The Hamilton Rating Scale for Depression as well as scales measuring impairment in activities of daily living, intellectual functioning, and social functioning were administered. The patients' CT scans were also examined.
Seventeen patients had major depression and two had minor depression. The presence of left dorsolateral frontal lesions and/or left basal ganglia lesions and, to a lesser extent, parietal-occipital and right hemisphere lesions was associated with an increased probability of developing major depression. Compared to the nondepressed group, the group with major depression had a higher frequency of previous psychiatric disorder and showed evidence of poorer social functioning.
Major depression occurs in about one-quarter of patients after traumatic brain injury. This is the same frequency as in other major disorders such as stroke. Major depression appears to be provoked by one or more factors that include poor premorbid social functioning and previous psychiatric disorder or injury to certain critical brain locations.

ABSTRACT: Objectives Major depression disorder (MDD) is the most frequent psychiatric complication after traumatic brain injury (TBI), with a prevalence of 14-77%. The aim of this study was to analyse the psychiatric sequelae of TBI, and to identify the neuropsychological and psychopathological correlates of post-TBI MDD in order to highlight their differences from those of primary MDD. Methods This was a longitudinal, prospective, case-control study. Sixteen patients with closed brain injury, and a lesion revealed by computed tomography (CT), were recruited and were evaluated one (T1), three (T3) and six (T6) months after discharge from Neurosurgery Department; the controls were six patients with MDD. The psychiatric symptoms were evaluated using Brief Psychiatric Rating Scale (BPRS), Hamilton Depression Rating Scale (HRSD), Beck Depression Inventory Scale (BDI), Hamilton Anxiety Rating Scale (HRSA), Global Assessment of Functioning (GAF) and Instrumental Activity of Daily Living (IADL). Neuropsychological profiles were assessed by using neuropsychological tests, focused on memory and frontal-executive functioning. Results At T1, MDD was observed in 10 cases (62.5%), a manic episode in 12.5%, and post-traumatic stress disorder in 6.5%. At T3 and T6, MDD was diagnosed in respectively eight (50%) and six cases (37.5%). Post TBI MDD had less severe depressive symptoms, showed greater social isolation and hostility and more cognitive deficits in comparison with the control group. Conclusions MDD is a frequent TBI complication. Patients with post-TBI MDD have a specific psychopathological profile characterised by a less severe depressive symptomatology and a neuropsychological pattern that is significantly associated with greater deficits in cognitive functions than those with primary MDD.Asian Journal of Psychiatry 08/2014; DOI:10.1016/j.ajp.2014.07.003

ABSTRACT: Rates of major depressive disorder (MDD) following traumatic brain injury (TBI) are estimated to be between 20% and 45%, a higher prevalence than that seen in the general population. These increased rates may be due to specific changes in brain function following TBI. Event related potentials (ERPs) are well suited for measuring the electrophysiological differences between groups in areas of cognitive processing impaired in both MDD and TBI, such as response inhibition. The current study presented an emotional Go/Nogo task (with schematic emotional faces as stimuli) to participants with TBI, participants with MDD, and participants with both TBI and MDD (TBI-MDD). Topographical distribution of activity and global field power comparisons were made across stimulus-locked epochs between these groups and healthy controls. The results indicated that ERPs were not altered by TBI alone. Both MDD and TBI-MDD groups showed similar alterations in topographical distribution and global field power in the N2 window, as well as late epoch alterations. The MDD and TBI-MDD groups showed significantly less fronto-central negativity during the N2 window in Nogo trials compared with the control group. The MDD and TBI-MDD groups also showed significantly less global field power in Nogo trials than Go trials during the N2 window while the control group showed the opposite pattern. The MDD and TBI-MDD groups showed no mood-congruent bias in behavioural or ERP measures. The results suggest that TBI-MDD displays similar electrophysiological changes to those found in the MDD group without TBI.Psychiatry Research Neuroimaging 12/2014; DOI:10.1016/j.pscychresns.2014.09.008 · 2.83 Impact Factor
