BACKGROUND Neurofunctional changes underlying effective antianxiety treatments are incompletely characterized. This study explored the effects of citalopram and cognitive-behavioral therapy on regional cerebral blood flow (rCBF) in social phobia. METHODS By means of positron emission tomography with oxygen 15-labeled water, rCBF was assessed in 18(More)
OBJECTIVE The central nervous system representation of social phobia (social anxiety disorder) is largely unknown. The aim of this study was to examine brain activity during symptom provocation in social phobics. METHOD Positron emission tomography with the use of (15)O water was used to measure regional cerebral blood flow (rCBF) in 18 subjects with(More)
BACKGROUND The aim was to examine the neural correlates of anxiety elicited by the anticipation of public speaking in individuals with social phobia. Positron emission tomography and (15)O-water was used to measure regional cerebral blood flow in subjects with DSM-IV defined social phobia during anxiety anticipation. Heart rate and subjective anxiety were(More)
A functional polymorphism in the promoter region of the human serotonin transporter (5-HTT) gene has been related to negative affect and amygdala activity. We studied amygdala activation during social anxiety provocation in relation to affective ratings and 5-HTT genetic variation. [H2(15)O]positron emission tomography was used to estimate amygdala blood(More)
The effect of the selective serotonin reuptake inhibitor citalopram was studied in a randomized, double-blind, placebo-controlled, 4-month trial in patients with the fibromyalgia syndrome (FMS) who all fulfilled the American College of Rheumatology criteria. The citalopram doses varied between 20-40 mg daily. Forty female patients, 21 patients in the(More)
The substrate for the second enzymatic step in serotonin synthesis, 5-hydroxy-L-tryptophan, labeled in the beta-position ([11C]-HTP), was used for positron emission tomography (PET) measurements in six healthy human participants, examined on two occasions. One- and two-tissue kinetic compartment modeling of time-radioactivity curves was performed, using(More)
BACKGROUND Depressive symptoms are potential outcomes of poorly functioning work environments. Such symptoms are frequent and cause considerable suffering for the employees as well as financial loss for the employers. Accordingly good prospective studies of psychosocial working conditions and depressive symptoms are valuable. Scientific reviews of such(More)
The aim was to investigate the relationship between life events and social phobia. An inventory assessing life events during childhood, adulthood as well as life events experienced in relation to the onset of the disorder was administrated to 30 subjects with a DSM-IV diagnosis of social phobia. They were recruited by announcement and diagnosed by the(More)
The present study investigated personality dimensions by means of the Temperament and Character Inventory (TCI) in subjects with social phobia with or without a co-existing avoidant personality disorder. Thirty-one individuals with social phobia were recruited through advertisement and diagnosed with the Structured Clinical Interview for DSM-IV I and II(More)
