Posted March 9, 2006 Men have a greater prepulse inhibition than females. FALSE 6: Ludewig K, Ludewig S, Seitz A, Obrist M, Geyer MA, Vollenweider FX. The acoustic startle reflex and its modulation: effects of age and gender in humans.Biol Psychol. 2003 Jul;63(3):311-23. Seventeen males and 16 female participants were tested three times at monthly intervals. Aged participants showed significantly lower startle magnitude and significantly more habituation than younger participants, but there was no effect of age on PPI or prepulse facilitation. Moreover, there were[highlight] no effects of gender on startle magnitude, PPI, prepulse facilitation, or habituation measures.[/highlight] Healthy males and females exhibited stable startle magnitudes and PPI across sessions. The results demonstrated that PPI and startle are reliable measures of sensory information processing in both genders and that startle magnitude and habituation are age-dependent measures.

Posted March 11, 2006 Thanks khuram... gets us out of the tedium!!Shoplifting is associated with bulimia nervosa TRUE - poor impulse controlAnorexia nervosa of later onset has higher mortality..... than that of earlier onset.

FALSE - this is mpre to do with post natal depression and pn psychosisBulimia is associated with increased mortality FALSE ?? tricky one, i think it is false true for anorexia thoughIn treatment of anorexic patients with severe weight loss, initial weight gain is associated by cognitive improvement grrrrrr can someone answer thissss and confrim the one above!!The effect of cortisol is more than that of DHEA in adolescent depressionYRUe increase cortisol to dhea ratio Leukoariosis in old age is seen in anxiety and depression TRUEDexamethasone non-suppression can be diagnostic of depression bllll 60% have it would be a poor test coz lots of non depressed people also have this.FALSEThe differences in scores between BDI and HAM-D are due to the way they are conducted FALSE - ok one is self and the other oserver marked... but they are just 2 completely different schedules, with diff questions, different vaalidity reliability..... anyone :-[Use of a light box for Seasonal Affective Disorder is equally effective when used in the morning or the evening FALSE - better in the morning manchesterImipramine and ECT work synergistically. ??FalseFirst onset of depression in a man aged 65 without any previous history of depression is likely to be dementia ??...

Posted August 30, 2006 Men have a greater prepulse inhibition than females. trueSex effects in prepulse inhibition and facilitation of the acoustic startle response: implications for pharmacological and treatment studies Ingrid Aasen Department of Psychology, Division of Psychological Medicine, Institute of Psychiatry, London, UK, i.aasen@iop.kcl.ac.uk Lavanya Kolli Department of Psychology, Institute of Psychiatry, London, UK Veena Kumari Department of Psychology, Psychological Medicine, Institute of Psychiatry, London, UK Journal of Psychopharmacology, Vol. 19, No. 1, 39-45 (2005)DOI: 10.1177/0269881105048890© 2005 British Association for PsychopharmacologyPrepulse inhibition (PPI) refers to the reduction in the response amplitude to a startling stimuli (pulse) if it is preceded (i.e. 30-500 ms) by a weak stimulus (prepulse). If the time interval between the prepulse and pulse is more than 500 ms, then an increase in this response amplitude can be seen, termed prepulse facilitation (PPF). PPI is thought to represent an operational index of sensorimotor function whereas PPF is thought to reflect, at least to some degree, sustained attention. Interestingly, PPI is found to be sexually dimorphic, with men exhibiting more PPI than women when subjects are tested without regard to where they are in the menstrual cycle, and to be impaired in several neuropsychiatric disorders known to exhibit sex differences in their clinical presentation. PPF has received relatively less attention in both normal and clinical studies. This study examined sex differences in both PPI and PPF in 62 healthy subjects (34 women, 28 men) using a range of prepulse-to-pulse intervals to elicit PPI (30, 60, 120, 240 and 480 ms) and PPF (1000 and 2000 ms). Men showed higher PPI than women but women showed higher PPF compared to men. These results suggest that reduced PPI in healthy women is not a simple reduction but rather a shift of the inhibition/facilitation curve in the direction of facilitation in women, relative to men. Future studies investigating pharmacological and treatment effects using a prepulse modification paradigm in normal and clinical populations of both sexes would benefit from an examination of sex effects and assessments of both PPI and PPF.
