Randomized Controlled TrialA randomized, double-blind trial of repetitive transcranial magnetic stimulation in obsessive-compulsive disorder with three-month follow-up.
Recent findings indicate that the motor and premotor cortices are hyperexcitable in obsessive-compulsive disorder (OCD). The authors have performed the first randomized, double-blind clinical trial of repetitive transcranial magnetic stimulation (rTMS) in OCD, with a 3-month follow-up. ⋯ After 14 weeks, the response rate was 41% (7/12) with active and 10% (1/10) with sham treatment. At 14 weeks, patients receiving active rTMS showed, on average, a 35% reduction on the Y-BOCS, as compared with a 6.2% reduction in those receiving sham treatment.

Human medial forebrain bundle (MFB) and anterior thalamic radiation (ATR): imaging of two major subcortical pathways and the dynamic balance of opposite affects in understanding depression.
The medial forebrain bundle (MFB), a key structure of reward-seeking circuitry, remains inadequately characterized in humans despite its vast importance for emotional processing and development of addictions and depression. Using Diffusion Tensor Imaging Fiber Tracking (DTI FT) the authors describe potential converging ascending and descending MFB and anterior thalamic radiation (ATR) that may mediate major brain reward-seeking and punishment functions. Authors highlight novel connectivity, such as supero-lateral-branch MFB and ATR convergence, caudally as well as rostrally, in the anterior limb of the internal capsule and medial prefrontal cortex. These anatomical convergences may sustain a dynamic equilibrium between positive and negative affective states in human mood-regulation and its various disorders, especially evident in addictions and depression.

ReviewWhat are the opportunities for EEG-based monitoring of delirium in the ICU?
Recognition of delirium in intensive care unit (ICU) patients is poor, despite the use of screening tools. Electroencephalography (EEG) with a limited number of electrodes and automatic processing may be a more sensitive approach for delirium monitoring. ⋯ The relative power of the theta and alpha frequency band most often (7/14 studies) distinguished delirium from non-delirium subjects. Given the feasibility for continuous EEG monitoring in ICU, EEG delirium monitoring in ICU patients is promising.

Psychiatric disorders after pediatric traumatic brain injury: a prospective, longitudinal, controlled study.
The objective was to examine the effects of traumatic brain injury (TBI), as compared with orthopedic injury (OI), relative to the risk for psychiatric disorder. There has only been one previous prospective study of this nature. Participants were age 7-17 years at the time of hospitalization for either TBI (complicated mild-to-severe) or OI. ⋯ This difference was not accounted for by pre-injury lifetime psychiatric status; pre-injury adaptive functioning; pre-injury family adversity, family psychiatric history, socioeconomic status, injury severity, or age at injury. Furthermore, none of these variables significantly discriminated between children with TBI who developed, versus those who did not develop, NPD. These findings suggest that children with complicated mild-to-severe TBI are at significantly higher risk than OI-controls for the development of NPD in the first 3 months after injury.
