Rational self-directed hypnotherapy: a treatment for panic attacks.

A single-subject research design was employed to assess the efficacy of rational self-directed hypnotherapy in the treatment of panic attacks. Presenting symptoms were acute fear, dizziness, constricted throat, upset stomach, loss of appetite, loss of weight, insomnia, fear of doctors, and fear of returning to work. Treatment lasted 13 weeks plus a 2-week baseline and posttherapy period and a 6-month follow-up. Objective measurements (MMPI, TSCS, POMS) and self-report assessments (physiological symptoms and a subjective stress inventory) were implemented. Using hypnosis and guided imagery, the subject reviewed critical incidents identifying self-defeating components within a cognitive paradigm, revising and rehearsing these incidents. Results showed an increased sense of control, improved self-concept, elimination of pathological symptoms, and cessation of panic attacks.

Time perception and hemodialysis.

Subtle alterations in neurological function are often difficult to identify and even harder to quantitate. The identification of a neurotoxic state existing before overt behavioral changes occur has eluded quantification. It was hypothesized that a challenging signal-detection procedure would be used to assess neurological function of dialysis patients and other subjects, the degree of uremic toxicity occuring during an interdialytic interval, and the effects of neuroactive drugs. A vigilance task demanding the detection of an irregularly flashing light from a matrix of regularly flashing lights was administered to 3 groups of 15 men: patients undergoing maintenance hemodialysis, patients with chronic illness and no kidney disease, and healthy subjects. The procedure was found to yield a reliable measure; average test-retest correlation was 0.93, which differentiated not only within the hemodialysis cycle (p less than 0.001), between groups (p less than 0.001), but was also related to the recency of neuroactive drugs ingested (p less than 0.01).
