Present and previous psychopathology of juvenile onset migraine: a pilot investigation by Child Behavior Checklist.

The objective was to describe the premorbid state of migraine with juvenile onset. Thirty subjects with migraine and 30 healthy subjects were enrolled in a case-control study. A structured questionnaire (Child Behavior Checklist, CBCL) was administered to the mothers and ratings were obtained for the past two age periods (0-3 and 4-6 years) and for the present state. CBCL scores of the migraine group (MG) were compared to those of the control group (CG) during the three periods. A longitudinal study was performed to evaluate the evolution of psychopathology comparing CBCL scores of MG in the three age periods. During the premorbid period MG showed significantly higher mean scores on total, internalising, anxious-depressive scales. In the longitudinal perspective, internalising traits were present in the premorbid period in MG. Children later diagnosed as having migraine differ from CG in several scales during different age periods. Migraine could be considered as the expression of a previous vulnerability.

Phase control of intermittency in dynamical systems.

We present a nonfeedback method to tame or enhance crisis-induced intermittency in dynamical systems. By adding a small harmonic perturbation to a parameter of the system, the intermittent behavior can be suppressed or enhanced depending on the value of the phase difference between the main driving and the perturbation. The validity of the method is shown both in the model and in an experiment with a CO2 laser. An analysis of this scheme applied to the quadratic map near crisis illustrates the role of phase control in nonlinear dynamical systems.
