Multicenter study comparing paroxetine (n=30) versus thermal cure (n=30) in patients with a diagnosis of Generalised Anxiety Disorders
Main objective is to quantify the therapeutic benefit of a thermal cure on generalized anxiety disorders and to understand the psycho-biological substrates of this improvement.
Secondary objectives:
A decrease of Insula activity at rest during the answers to aversive pictures and during the task of subjective measurement of heartbeat.
A decrease of sensibility to emotional interference by subliminal presentation of emotional words thanks to a lexical task and a color recognition task associated to simultaneous measurement of physiological indicator of emotional activity ( dermal resistance)
Deroxat® (20 mg/day) 3 week; can be increase on week 2 until 50 mg.
Thermal cure is realized for 3 weeks
Paroxetine (Deroxat®) Posology : 20 mg per day for 3 weeks. After 2 weeks of treatments, if indicated, physicians will prescribe until 50 mg.
This study is controlled with a comparator which is the Thermal cure. Thermal cure is realized for 3 weeks.
