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.

Clinical TrialAssociations between bilateral subthalamic nucleus deep brain stimulation (STN-DBS) and anxiety in Parkinson's disease patients: a controlled study.
The authors explored the associations between subthalamic nucleus deep brain stimulation (STN-DBS) and anxiety in Parkinson's disease (PD) patients. Recent research suggests that anxiety may be one of the earliest manifestations of PD; however, the lack of a dopamine-medication control group is a major limitation of these studies. Authors paired a group of 31 bilateral STN-DBS PD patients (STN-DBS group) with 31 dopamine-medicated PD patients (Medication-control group) and used various psychological assessment scales for group evaluations. ⋯ Anxiety scores remained stable before 3rd-month Stimulator Power-On, but got worse after that time. In the STN-DBS group, S-AI was positively related to motor symptoms and life quality preoperatively and 4 months postoperatively, but, in the Medication group, this correlation existed throughout the study. PD-related anxiety decreased in STN-DBS patients because of the improvement in motor function for a short time; however, as the voltages and pulse-widths grew higher with time, the PD-related anxiety became worse.
