Motor laterality as an indicator of speech laterality.

Objective: The determination of speech laterality, especially where it is anomalous, is both a theoretical issue and a practical problem for brain surgery. Handedness is commonly thought to be related to speech representation, but exactly how is not clearly understood. This investigation analyzed handedness by preference rating and performance on a reliable task of motor laterality in 34 patients undergoing a Wada test, to see if they could provide an indicator of speech laterality.

Attentional control in patients with temporal lobe epilepsy.

Across different studies, patients with temporal lobe epilepsy (TLE) demonstrate impairments on numerous measures of attentional control that are classically associated with frontal lobe functioning. One aspect of attentional control that has not been examined in TLE is the ability to execute two modality-specific tasks concurrently. We sought to examine the status of dual-task coordination in TLE.

Controlled recall of verbal material in temporal lobe epilepsy.

This study used a guided process-dissociation procedure to examine the contribution of controlled and automatic uses of memory to a cued-recall task in 24 patients with unilateral temporal lobe epilepsy (TLE: 12 left-sided; 12 right-sided), and 12 neurotypical controls. In an inclusion task, participants attempted to complete three-letter word stems using previously studied words, in an exclusion task they aimed to avoid using studied words to complete stems. Patients with left TLE produced fewer target completions under inclusion conditions.

Chance guessing in a forced-choice recognition task and the detection of malingering.

Guessing occurs on forced-choice (FC) tests for which responses cannot be based on relevant knowledge. Its importance is in inverse relation to the level of knowledge being measured, so that it becomes an increasing component of test scores as the level of knowledge decreases. It is also used as a benchmark to detect simulated impairment.

Attention and executive function in people with schizophrenia: Relationship with social skills and quality of life.

Objective. Executive function and attention are highly complex cognitive constructs that typically reveal evidence of impairment in people with schizophrenia. Studies in this area have traditionally utilised abstract tests of cognitive function and the importance of using more ecologically valid tests has not been extensively recognised.

A case of ulnar positive variance found on x-ray.

A briefcase report is presented that demonstrates the advantage of the therapist's viewing of a series of wrist x-rays in guiding the clinical management of a patient with an ulnar plus configuration. The positive findings revealed on these images facilitated an improved outcome. This case is offered to encourage therapists to routinely look at x-rays in their clinical practice.

Cognitive function and social abilities in patients with schizophrenia: relationship with atypical antipsychotics.

Although atypical antipsychotics have been associated with improvements in cognitive function in schizophrenia, the neurochemical basis for such effects is not well understood. Candidate neurotransmitter systems primarily involve dopamine and serotonin. The current study explored this issue by examining the cognitive abilities, social function and quality of life in patients with schizophrenia who were medicated with atypical antipsychotics.

Pretreatment with hyperbaric oxygen and its effect on neuropsychometric dysfunction and systemic inflammatory response after cardiopulmonary bypass: a prospective randomized double-blind trial.

Objective: Animal studies have shown that pretreatment with hyperbaric oxygen can induce central nervous system ischemic tolerance and also modulate the inflammatory response. We evaluated this therapy in patients undergoing cardiopulmonary bypass.

Methods: Sixty-four patients were prospectively randomized to group A (n = 31; atmospheric air, 1.
