    Description / Table of Contents: Summary In children and adolescents motor/vocal tics and obsessive-compulsive behavior are known to be closely related. Thereby, a continuum of symptoms ranging from single tics to a mixed picture of tics/rituals/obsessive-compulsive traits to clinically relevant obsessions and compulsions could be described. As neurobiological substrates dysfunctions in corresponding cortico-striato-thalamo-cortical circuits (sensorimotor circuit in tic symptomatology, orbitofrontal circuit in obsessive-compulsive behavior) were postulated. For both disturbances behavioral therapy can be used to improve control mechanisms to counterregulate tics and obsessive-compulsive behavior, respectively, and psychopharmacological agents can be administerd to compensate dysbalances in neurotransmitter systems. In case of a mixed symptomatologic picture it is necessary to include interventions for both pols of the symptom-continuum in the therapeutic programme to achieve extensive improvement as a basis for a further positive development of the patient.
    Notes: Zusammenfassung Motorische/vokale Tics und zwanghafte Verhaltensweisen kommen bei Kindern und Jugendlichen häufig gemeinsam vor; dabei kann ein Symptomkontinuum von solitär auftretenden Tics über ein Mischbild von Tics und Ritualen/zwanghaften Gedanken und/oder Handlungen bis hin zu eindeutigen Zwangsphänomenen beschrieben werden. Neurobiologisch können diesem Symptomkontinuum unterschiedlich ausgebreitete Dysfunktionen entsprechender kortiko-striato-pallido-thalamo-kortikaler Regulationssysteme zugrunde liegen. Therapeutisch lassen sich bei beiden Verhaltensauffälligkeiten mittels verhaltenstherapeutischer Techniken Steuerungs- und Kontrollmöglichkeiten zur Gegenregulation der Auffälligkeiten verbessern sowie durch Einsatz von Psychopharmaka Dysbalancen von Neurotransmittersystemen ausgleichen. Bei einem Mischbild von Tics und Zwängen sind therapeutische Interventionen für beide Zielbereiche erforderlich. Nur so können umfassende Verbesserungen erreicht und günstige Entwicklungsbedingungen für die betroffenen Kinder und Jugendlichen eröffnet werden.

    Beyond discounting: possible experimental models of impulse control (1999)

    Notes: Abstract  Animal studies of impulsivity have typically used one of three models: a delay of reward procedure, a differential reinforcement for low rate responding (DRL) procedure, or an autoshaping procedure. In each of these paradigms, we argue, measurement of impulsivity is implicitly or explicitly equated with the effect delay has on the value of reward. The steepness by which delay diminishes value (the temporal discount function) is treated as an index of impulsivity. In order to provide a better analog of human impulsivity, this model needs to be expanded to include the converse of impulsivity – self-control. Through mechanisms such as committing to long range interests before the onset of temptation, or through bundling individual choices into classes of choices that are made at once, human decision-making can often look far less myopic than single trial experiments predict. For people, impulsive behavior may be more often the result of the breakdown of self-control mechanisms than of steep discount functions. Existing animal models of self-control are discussed, and future directions are suggested for psychopharmacological research.

    A double-blind, randomized, placebo-controlled, multi-center study of brofaromine in the treatment of post-traumatic stress disorder (1995)

    Notes: Abstract A large multi-center, double-blind, parallel trial to assess the efficacy of brofaromine in the treatment of post traumatic stress disorder (PTSD) failed to show a significant difference between the brofaromine and placebo treatment groups. The placebo response rate in this study was higher than that in previously published double-blind, placebo-controlled studies of PTSD.
