Ten-year follow-up study of PTSD diagnosis, symptom severity and psychosocial indices in aging holocaust survivors

ACTA PSYCHIATRICA SCANDINAVICA, Issue 1 2009
R. Yehuda
Objective:, We performed a longitudinal study of holocaust survivors with and without post-traumatic stress disorder (PTSD) by assessing symptoms and other measures at two intervals, approximately 10 years apart. Method:, The original cohort consisted of 63 community-dwelling subjects, of whom 40 were available for follow-up. Results:, There was a general diminution in PTSD symptom severity over time. However, in 10% of the subjects (n = 4), new instances of delayed onset PTSD developed between time 1 and time 2. Self-report ratings at both assessments revealed a worsening of trauma-related symptoms over time in persons without PTSD at time 1, but an improvement in those with PTSD at time 1. Conclusion:, The findings suggest that a nuanced characterization of PTSD trajectory over time is more reflective of PTSD symptomatology than simple diagnostic status at one time. The possibility of delayed onset trajectory complicates any simplistic overall trajectory summarizing the longitudinal course of PTSD. [source]


Risk-taking and the adolescent brain: who is at risk?

DEVELOPMENTAL SCIENCE, Issue 2 2007
Adriana Galvan
Relative to other ages, adolescence is described as a period of increased impulsive and risk-taking behavior that can lead to fatal outcomes (suicide, substance abuse, HIV, accidents, etc.). This study was designed to examine neural correlates of risk-taking behavior in adolescents, relative to children and adults, in order to predict who may be at greatest risk. Activity in reward-related neural circuitry in anticipation of a large monetary reward was measured with functional magnetic resonance imaging, and anonymous self-report ratings of risky behavior, anticipation of risk and impulsivity were acquired in individuals between the ages of 7 and 29 years. There was a positive association between accumbens activity and the likelihood of engaging in risky behavior across development. This activity also varied as a function of individuals' ratings of anticipated positive or negative consequences of such behavior. Impulsivity ratings were not associated with accumbens activity, but rather with age. These findings suggest that during adolescence, some individuals may be especially prone to engage in risky behaviors due to developmental changes in concert with variability in a given individual's predisposition to engage in risky behavior, rather than to simple changes in impulsivity.

Supraspinal Modulation of Trigeminal Nociception and Pain

HEADACHE, Issue 5 2009
Amy E. Williams MA
Objective., This study examined modulation of trigeminal pain/nociception by 2 supraspinal mechanisms: emotional controls of nociception and diffuse noxious inhibitory controls. Background., Prior research suggests emotional picture viewing (emotional controls) and tonic noxious stimuli (diffuse noxious inhibitory controls) engage supraspinal mechanisms to modulate pain and nociceptive processes. It is currently unknown, however, whether emotional controls modulate trigeminal pain and nociception. Additionally, the influences of emotional controls and diffuse noxious inhibitory controls have not been compared in the same group of participants. Methods., Noxious electrodermal stimuli were delivered to the trigeminal nerve using a concentric electrode designed to selectively activate nociceptive fibers. Trigeminal nociception and pain were assessed (34 participants) from the nociceptive blink reflex and pain ratings, respectively. Emotional controls were engaged by presentation of standardized picture stimuli (pleasant, neutral, and unpleasant) shown to reliably evoke pleasure-induced inhibition and displeasure-induced facilitation of pain and nociception. Diffuse noxious inhibitory controls were engaged with a forearm ischemia task. Results., Trigeminal pain (self-report ratings) and nociception (blinks) were facilitated by unpleasant pictures and inhibited by pleasant pictures. Emotion induction (as assessed from trend analysis) explained 51% of the variance in trigeminal pain and 25% of the variance in trigeminal nociception. Additionally, forearm ischemia inhibited trigeminal pain but not nociception. The baseline vs ischemia comparison explained 17% of the variance in pain report and 0.1% of the variance in blinks. Supraspinal modulation by emotional controls and diffuse noxious inhibitory controls were uncorrelated. Conclusions., Emotional controls and diffuse noxious inhibitory controls modulated trigeminal pain and emotional controls modulated trigeminal nociception. These procedures can be used to study supraspinal modulation of nociceptive processing in disorders of the trigeminal pain system, including headache. [source]


Concurrent validity of the Yale,Brown Obsessive,Compulsive Scale,Symptom checklist,

Abstract Despite the frequent use of the Yale,Brown Obsessive,Compulsive Scale,Symptom Checklist (Y-BOCS-SC; Goodman et al., 1989a) and the Obsessive,Compulsive Inventory-Revised (OCI-R; Foa et al., 2002), there are limited data on the psychometric properties of the two instruments. In the present research, clinician ratings on the Y-BOCS-SC for 112 patients with obsessive,compulsive disorder (OCD) were compared to their self-report ratings on the OCI-R. In addition, Y-BOCS-SC and OCI-R scores were compared to measures of OCD symptom severity and self-report measures of anxiety (State,Trait Anxiety Inventory,Trait Subscale [STAI-T]; Spielberger, Gorusch, & Lushene, 1970) and depression (Beck Depression Inventory-II [BDI-II]; Beck, Steer, & Brown, 1996). The six symptom scales of the OCI-R had good internal consistency reliabilities (,s). For the Y-BOCS-SC, three of five scales had good reliabilities (,s >.80), but ,s for symmetry/ordering and sexual/religious symptom scales were inadequate. Total scores for the two instruments were strongly correlated with their corresponding "checking" scales, but no individual symptoms scales were identified as indices of overall OCD symptom presence. Scales assessing washing/contamination, symmetry/ordering, and hoarding from the two OCD instruments correlated well, but lower correlations for the other scales suggested differences in symptom coverage by the two instruments. Most symptom scales from the Y-BOCS-SC and OCI-R had low correlations with the BDI-II and STAI-T, but the OCI-R obsessing scale was well correlated (r=.54) with the STAI-T. These findings reveal some of the strengths and weaknesses of these two OCD instruments, and the results provide guidance for selecting scales that are suitable for measuring OCD symptoms. © 2008 Wiley Periodicals, Inc.

Early- and late-onset startle modulation in unipolar depression

PSYCHOPHYSIOLOGY, Issue 3 2004
Gabriel S. Dichter
Abstract In two experimental sessions, we assessed early- and late-onset acoustic startle eyeblink modulation and subjective ratings of emotional pictures by nondepressed participants and by unipolar depressed participants. Depressed participants were assessed before and after treatment with the antidepressant medication Bupropion SR. Both depressed and nondepressed participants exhibited arousal-dependent startle modulation to early probes occurring 300 ms after picture onset. Nondepressed participants demonstrated the expected valence-dependent startle modulation to late probes (3,500,4,500 ms post-onset). In contrast, the late-probe blink magnitudes of depressed patients were unrelated to picture valence. This pattern of group differences was not moderated by treatment. There were no between-group differences in self-report ratings to pictures. These results suggest that depression may be characterized by anomalous responses to affective stimuli and that startle modulation can be a more sensitive index of affective response deficits linked to depression than self-report measures.

The Inhibitory Effects of Nicotine on Physiological Sexual Arousal in Nonsmoking Women: Results from a Randomized, Double-Blind, Placebo-Controlled, Cross-Over Trial

THE JOURNAL OF SEXUAL MEDICINE, Issue 5 2008
Christopher B. Harte BA
ABSTRACT Introduction., Extensive research suggests that long-term cigarette smoking is an independent risk factor for the introduction of sexual dysfunction in men. However, results of limited data investigating this relationship in women are mixed. No studies have examined the acute effects of tobacco or nicotine on physiological sexual response in women. Controlled experimental studies examining acute effects of isolated nicotine intake on female physiological sexual responses are necessary in order to help elucidate tobacco's potential role in the development and/or maintenance of sexual impairment in women. Aim., To examine whether isolated nicotine intake acutely affects sexual arousal responses in nonsmoking women. Methods., Twenty-five sexually functional women (mean age = 20 years) each with less than 100 direct exposures to nicotine completed two counterbalanced conditions in which they were randomized to received either nicotine gum (6 mg) or placebo gum, both administered double-blind and matched for appearance, taste, and consistency, approximately 40 minutes prior to viewing an erotic film. Main Outcome Measures., Physiological (changes in vaginal pulse amplitude via vaginal photoplethysmography) and subjective (continuous self-report) sexual responses to erotic stimuli were examined, as well as changes in mood. Results., Nicotine significantly reduced genital responses to the erotic films (P = 0.05), corresponding to a 30% attenuation in physiological sexual arousal. This occurred in 11 of 18 women with valid physiological assessments. Nicotine had no significant effect on continuous self-report ratings of sexual arousal (P = 0.45), or on mood (all Ps > 0.05). Conclusions., Acute nicotine intake significantly attenuates physiological sexual arousal in healthy nonsmoking women. Our findings provide support to the hypothesis that nicotine may be the primary pharmacological agent responsible for genital hemodynamic disruption, thereby facilitating a cascade of biochemical and vascular events which may impair normal sexual arousal responses.
