Abstract

BACKGROUND: Mood, cognitive, and behavioural changes have been reported with deep brain stimulation (DBS) in the thalamus, globus pallidus interna, and anterior limb of the internal capsule/nucleus accumbens region. OBJECTIVE: To investigate panic and fear resulting from DBS. METHODS: Intraoperative DBS in the region of the right and then left anterior limb of the internal capsule and nucleus accumbens region was undertaken to treat a 52 year old man with treatment refractory obsessive-compulsive disorder (OCD). Mood, anxiety, OCD, alertness, heart rate, and subjective feelings were recorded during intraoperative test stimulation and at follow up programming sessions. RESULTS: DBS at the distal (0) contact (cathode 0-, anode 2+, pulse width 210 ms, rate 135 Hz, at 6 volts) elicited a panic attack (only seen at the (0) contact). The patient felt flushed, hot, fearful, and described himself as having a "panic attack." His heart rate increased from 53 to 111. The effect (present with either device) was witnessed immediately after turning the device on, and abruptly ceased in the off condition CONCLUSIONS: DBS of the anterior limb of the internal capsule and nucleus accumbens region caused severe "panic." This response may result from activation of limbic and autonomic networks.

Event-related potential evidence for the processing efficiency theory.

The purpose of this study was to examine the central tenets of the processing efficiency theory using psychophysiological measures of attention and effort. Twenty-eight participants were divided equally into either a high or low trait anxiety group. They were then required to perform a simulated driving task while responding to one of four target light-emitting diodes. Cortical activity and dual task performance were recorded under two conditions -- baseline and competition -- with cognitive anxiety being elevated in the competitive session by an instructional set. Although driving speed was similar across sessions, a reduction in P3 amplitude to cue onset in the light detection task occurred for both groups during the competitive session, suggesting a reduction in processing efficiency as participants became more state anxious. Our findings provide more comprehensive and mechanistic evidence for processing efficiency theory, and confirm that increases in cognitive anxiety can result in a reduction of processing efficiency with little change in performance effectiveness.

Brief report: testing the factorial invariance of the CBCL Somatic Complaints scale as a measure of internalizing symptoms for children with and without chronic illness.

OBJECTIVE: To examine the factorial invariance of the Somatic Complaints subscale of the Child Behavior Checklist as a measure of Internalizing Behavior Problems across a sample of children with and without spina bifida. METHODS: Multisample confirmatory factor analysis was used to compare mother and father report on the Somatic Complaints subscale across a sample of children with spina bifida and a matched comparison sample of able-bodied children ages 8 through 11 years (N = 68 for mother report in each group; N = 54 for father report in the spina bifida group and 53 for the able-bodied group). RESULTS: Although there were no significant between-group differences in the magnitude of factor loadings, significantly more variance in scores on the Somatic Complaints scale was unrelated to Internalizing Behavior Problems for the spina bifida group, compared to the able-bodied group. There were no between-group differences when father data were analyzed, but the latent variable of Internalizing Behavior Problems explained little variance in the Somatic Complaints scale for either group. CONCLUSIONS: Maternal report of Somatic Complaints on the CBCL does not appear to measure Internalizing Behavior Problems in the same manner across groups of children with and without spina bifida. This suggests that the Somatic Complaints subscale should be interpreted with caution when measuring Internalizing Behavior Problems within this population.
