While controlled trials with SRIs have demonstrated a selective efficacy in obsessive-compulsive disorder (OCD), up to 40 -60% of patients do not have a satisfactory outcome. Non-response to treatment in OCD is associated with serious social disability. There are a large number of nonresponsive patients, and they are difficult to cluster due to ambiguities in diagnostic criteria, possibility of subtypes and a high rate of comorbidity. Moreover, the findings of current studies of ''so-called'' non-responsive cases are currently non-generalizable because of the lack of an operational definition of non-response. The result has been that a cumulative body of data on a reasonably homogeneous sample of non-responders has not been developed. The aims of the research in this area are to clarify some of the obstacles in defining stages of response and levels of non-response and, through a comprehensive analysis, to propose a systematic nosology for this rather common condition. Better characterization of which patients respond and do not respond to various treatments will enable more accurate clustering of patients, and help facilitate multisite data collection for future research trials. The authors reviewed also the more recent therapeutic pharmacological and psychological lines for the treatment of refractoriness in OCD. D
Social anxiety is a highly prevalent, disabling condition in outpatients with schizophrenia that is unrelated to clinical psychotic symptoms. The Liebowitz Social Anxiety Scale appeared adequate and reliable in assessing social anxiety disorder in patients with schizophrenia. If these data are confirmed, this study will make a contribution to the search for operational guidelines and adequate next-step treatments for social anxiety disorder in schizophrenia patients.
Level of concerns unexpected compared to the level reported in other countries for the behavioral compulsions, have been highlighted. Behavioral addictions are multiple, a source of disability, and they are related to substance abuse. It has yet to be clarified if they are a temporary phenomenon occurring in adolescents or if they are a stable trait, accounting as marker for the development of substance abuse.
The aim of the present study was to evaluate the efficacy and safety of lithium and valproate in nonbipolar pathological gamblers. Method: Forty-two subjects with DSM-IVdefined pathological gambling entered a 14-week single-blind trial with lithium (N = 23) or valproate (N = 19). A total of 15 subjects on lithium treatment and 16 patients on valproate treatment completed the 14-week protocol. Results: At the end of the 14-week treatment period, both the lithium and the valproate groups showed significant (p < .01) improvement in mean score on the Yale-Brown Obsessive Compulsive Scale modified for pathological gambling. This improvement did not significantly differ between groups. Fourteen (60.9%) of the 23 patients taking lithium and 13 (68.4%) of the 19 patients taking valproate were responders based on a Clinical Global Impressions-Improvement score of much or very much improved. Conclusion: Findings from the present study suggest the efficacy of both lithium carbonate and valproate in the treatment of pathological gambling. This is the first controlled trial of the efficacy of mood stabilizers in pathological gambling. A double-blind, placebo-controlled trial is required to confirm these findings.
Results from this study show that low-frequency rTMS over the right DLPFC, with a relatively low number of pulses (420 pulses per session) and a relatively short period of treatment, is effective in the treatment of resistant patients (in a sample also including elderly patients) in a 3-weeks treatment protocol with a low reduction with the progress of age. Furthermore, we found a greater response in younger patients and an inverse correlation between age and treatment response. Adaptations of the protocol according to age are reviewed.
Background: Clinical studies have shown that repetitive transcranial magnetic stimulation (rTMS) is effective in a certain percentage of treatment-resistant depression (TRD). The left dorsolateral prefrontal cortex (DLPFC) 10 Hz rTMS stimulation received FDA approval in 2008, although different rTMS protocols have also shown their effectiveness in reducing depressive symptoms. We investigated the clinical, cognitive and neurophysiologic effects of a 3 weeks’ protocol of low-frequency rTMS applied over the right DLPFC in resistant depression. Methods: Twenty-eight patients with TRD (age range 28–55) received low-frequency rTMS (1 Hz) over the right DLPFC in a 3-week open trial. Hamilton scales for depression and anxiety, Corsi block-tapping test, phonemic verbal fluency, right and left resting motor thresholds were evaluated in each subject over the trial period. Results: At the end of the trial 42.9% of the subjects were considered as responders. A significant reduction of both HAMD (p < 0.001) and HAMA (p < 0.01) total scores was observed. At the 3rd week, the performances in Corsi test (p < 0.02) and phonemic verbal fluency (p = 0.065) were improved independently from depressive symptoms variation. At the end of the rTMS protocol, a significantly decreased left hemisphere resting motor threshold was registered (p < 0.01), while right hemisphere resting motor threshold did not show significant variation. Conclusion: Low-frequency rTMS over the right DLPFC appeared effective in 42.9% of depressive resistant subjects in this sample. A significant decrease in left hemisphere resting motor threshold was observed only in responders, while a trend for improvement in cognitive function has been found and appeared independent from clinical response.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
