Case ReportsSuccessful treatment of hallucinations associated with sensory impairment using gabapentin.
Sensory impairment hallucinations, such as visual hallucinations with visual loss, may not respond to traditional treatments such as antipsychotics. In this case series, the authors describe four patients with either visual or musical hallucinations associated with sensory impairment who were successfully treated with gabapentin.

Comparative StudyA new data-based motor subtype schema for delirium.
The authors sought to validate a new approach to motor subtyping in delirium based on data from a controlled comparison of items from three existing psychomotor schema combined into the Delirium Motoric Checklist. Principal components analysis of the Delirium Motoric Checklist identified two factors that correlated significantly with independently assessed motor agitation and retardation. Symptoms loading at >0.65 were extracted to form subtype criteria composed of four hyperactive items and seven hypoactive items which, when applied to the delirious population, suggested a cutoff of two items for subtypes. This new scale is derived from existing approaches but is more concise, focused on motor disturbances, and validated against nondelirious comparison subjects and independently rated motor disturbance.

ReviewRecent neuroimaging techniques in mild traumatic brain injury.
Mild traumatic brain injury (TBI) is characterized by acute physiological changes that result in at least some acute cognitive difficulties and typically resolve by 3 months postinjury. Because the majority of mild TBI patients have normal structural magnetic resonance imaging (MRI)/computed tomography (CT) scans, there is increasing attention directed at finding objective physiological correlates of persistent cognitive and neuropsychiatric symptoms through experimental neuroimaging techniques. The authors review studies utilizing these techniques in patients with mild TBI; these techniques may provide more sensitive assessment of structural and functional abnormalities following mild TBI. Particular promise is evident with fMRI, PET, and SPECT scanning, as demonstrated by associations between brain activation and clinical outcomes.
