One type of emotional behavior called restlessness occurs when the anteromedial hypothalamus is stimulated in cats. We examined the changes in the distribution and surface expression of adhesion molecules in leukocytes accompanied with restlessness. Mature female cats were used for this study. The cats were stimulated with 60 Hz sine wave train pulses (20–90 μA, 10 s in duration, at 5-min intervals) for 60 min. Samples of blood were collected from 30 min before stimulation up to several hours after the final stimulation. The number of granulocytes increased just after stimulation, while at the same time the expression of L-selectin decreased. On the other hand, the number of CD4+ and CD8+ T lymphocytes decreased at 1–2 h after the end of the stimulation, while the expression of L-selectin increased. In addition, the expression of LFA-1 and VLA-4 did not change. These data suggest that hypothalamically elicited restlessness is thus accompanied by a leukocyte distribution change, which might be mediated by changes in the expression of L-selectin on leukocytes. Plasma cortisol increased during stimulation in restlessness. However, during in vitro culture experiments, cortisol did not alter the expression of leukocyte L-selectin which thus indicated that cortisol does not directly affect the surface expression of L-selectin. These results thus suggest that hypothalamically induced restlessness is a useful stress model for psychoneuroimmunological studies.

Objective: Time-processing disorders in adults is a priority area for intervention. Time management program, which has been demonstrated to be effective in children with ADHD, has not been examined in adults. We anticipate the need for the development of specialized programs for adults. This is because it has been reported that time processing disorders have different patterns in childhood and adulthood. This study aimed to evaluate the therapeutic effect of a gCBT program focusing on time management for adults with ADHD. Method: Adults with ADHD were randomly assigned to gCBT ( n = 24) or a treatment as usual group ( n = 24). Outcome measures were masked clinically rated, self-reported, and family-reported ADHD symptoms. Results: The gCBT group significantly reduced ADHD symptoms on all measures. Conclusion: Interventions focused on time management have been shown to be effective not only in children with ADHD but also in adult patients.
