Impulse control disorder in patients with Parkinson's disease under dopamine agonist therapy: a multicentre study.

Background: Impulse control disorders (ICDs) encompass a wide spectrum of abnormal behaviour frequently found in cases of Parkinson's disease (PD) treated with dopamine agonists (DAs). The main aim of this study was to analyse ICD prevalence with different DAs.

Methods: We carried out a multicentre transversal study to evaluate the presence of ICDs in patients with PD chronically treated (>6 months) with a single non-ergolinic DA (pramipexole, ropinirole, or rotigotine).

[Antoniana Margarita: Gómez Pereira, Francisco Lobato and the antecedents of cerebral mechanicism during the Spanish renaissance].

The year 2000 is the fifth century of the birth, in Medina del Campo (Vallodolid, Spain) of licenciado Perea (Gomez Perea or Pereira). A man of the Renaissance, he was an outstanding doctor, humanist, theologist, nominalist philosopher, naturalist and practical engineer. He developed the first modern theory of behavior, based purely on mechanicistic principles, describing his ideas in a text known by the curious title of Antoniana Margarita.
