BACKGROUND France has high rates of psychotropic drug consumption and suicide in the elderly population, but it has not yet been possible to determine whether this is due to exceptionally high morbidity rates. AIMS To describe the first longitudinal population study of psychiatric disorder undertaken in France, and to estimate current and lifetime(More)
This study assessed the efficacy, tolerability and safety of vortioxetine versus placebo in adults with recurrent major depressive disorder. This double-blind, randomized, placebo-controlled study included 608 patients [Montgomery-Åsberg Depression Rating Scale (MADRS) total score ≥ 26 and Clinical Global Impression - Severity score ≥ 4]. Patients were(More)
The percentage occupation of striatal dopamine D2 receptors has been evaluated in 25 patients using76Br-bromospiperone positron emission tomography (PET) and prolactin plasma levels (PRL) during oral neuroleptic treatment (11 studies), 1–90 days following discontinuation of such treatment (16 studies), and 1–120 days after last intramuscular administration(More)
OBJECTIVE This randomised, double-blind, fixed-dose study evaluated the efficacy of escitalopram and paroxetine in the long-term treatment of severely depressed patients with major depressive disorder (MDD). RESEARCH DESIGN AND METHODS Patients with a primary diagnosis of MDD and baseline Montgomery-Asberg Depression Rating Scale (MADRS) >or= 30 were(More)
OBJECTIVE Escitalopram has proven efficacy in the short-term treatment of generalized social anxiety disorder (SAD). The present relapse prevention study investigated relapse rates during a 24-week, randomized, double-blind, placebo-controlled period in patients with generalized SAD who had responded to 12-week open-label treatment with escitalopram.

Tryptophan hydroxylase (TPH) is the rate-limiting enzyme of serotonin synthesis. In this case-control study, we investigated whether the TPH gene was a susceptibility factor for suicidal behavior. Seven polymorphisms spanning the entire gene were studied in a case-control study including 231 individuals who had attempted suicide and 281 controls.(More)

The binding of [3H]Ro 5-4864 to the peripheral-type benzodiazepine binding site in brain is characterized. The binding is saturable, high-affinity (KD = 1.6 nM), and reversible. The comparison of [3H]Ro 5-4864 and [3H]diazepam binding sites reveals major differences which include the following. There are about one-fourth as many peripheral-type binding(More)
