Vous êtes d'un naturel impulsif ? Il vous arrive de prendre des décisions sans trop réfléchir ? Et bien sachez que cette impulsivité aurait des bases biologiques et plus particulièrement à la dopamine, un neurotransmetteur dans le cerveau. Risperdal (risperidone) was not originally intended to be used as an ADHD treatment, but its extensive off-label use has become a lightning rod for controversy, confusion, and anguish for parents whose children have suffered after using the powerful antipsychotic medication. View detailed reports from patients taking Risperidone who experienced impulsive behaviour. Reports are from official medical reports as well as online extractions from user reviews and forum discussions. Abstract: In the last years, second generation antipsychotics have shown to be useful in the treatment of disorders with predominant impulse dyscontrol symptoms, in particular borderline personality disorder (BPD) and impulse control disorders (ICDs). Children and adolescents with bipolar disorder are also at high risk of having comorbid attention-deficit hyperactivity disorder (ADHD). The objective of this study was to estimate improvement in ADHD symptoms in children with bipolar disorder. This was an open-label, study of risperidone Methylphenidate vs. Risperidone for the Treatment of Children and Adolescents With ADHD and Disruptive Disorders The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Abatement of aggression and impulsivity in this patient was rapid following the administration of risperidone. This enabled us to manage his aggression and impulsivity in the ward, and he was discharged without much trouble. Risperidone has a combined dopamine D2 and serotonin 5‐hydroxytryptamine (5HT2) receptor antagonism. Impulsivity is broadly defined as actions without foresight that are poorly conceived, prematurely expressed, unnecessarily risky, and inappropriate to the situation. Impulsivity is associated with undesirable, rather than desirable, outcomes. We reviewed the recent literature on medicines used to manage inattention, impulsiveness, and overactivity in children with pervasive developmental disorders (autistic disorder, pervasive developmental disorder not otherwise specified, Asperger’s disorder) using computer searches of pharmacological studies.
