Filter by:Learning includes the ability to generalize to new situations and respond to similar, yet not identical stimuli. In previous work, focused on stimulus generalization in healthy volunteers, tones that were negatively reinforced induce wider generalization curves than tones that were positively reinforced, and these in turn induce wider curves than neutral memory (Schechtman et al, 2010). The current study aimed to evaluate those patterns in different clinical disorders (including Schizophrenia, Bipolar disorder, MDD, Anxiety disorders (Panic and GAD) and PTSD, and healthy subjects that would be used as a control), with consideration whether those patterns are unique to any specific disorder or state. The generalization patterns evaluation would conduct twice though enable to compare the stability of those patterns during the course of the illness (i.e during remission compared to acute state). The basic paradigm based on conditioning of a tone (sound) with unpleasant noise, and extinction of that conditioning afterword. During the 60 minutes of evaluation, the capability to discriminate between the original tone and similar but not identical tones, and the tendency to categorize similar tones as identical to the original tone. A neutral tone without conditioning will be used as reference. The clinical diagnosis will conduct by a senior psychiatrist, and the state would be evaluated using standard questionnaires
Posttraumatic stress disorder (PTSD) occurs in some people after exposure to events that cause extreme fear or helplessness. The incidence of war zones worldwide and the prevalence of violence in large cities in the U.S., increases the likelihood that people will experience a traumatizing event in their lifetime. About 1 in 10 people who survive such events will develop PTSD, while most people will get better over time. This suggests that some people may have biological vulnerabilities that make it harder for them to recover. One of these biological risk factors may be related to how stress hormones work in people who get sick. Another is how people react to things that make them afraid or nervous, we have found that PTSD patients have higher than normal fear reactions. The part of the brain that reacts to fearful stimulation is linked to stress hormones; the purpose of this study is to examine how these systems interact. The study will suppress stress hormones (cortisol) production in one group of participants, while another will get a placebo. When their cortisol is suppressed, the participants will undergo a startle study to see if their fear responses are decreased. We expect that people PTSD will show a normal fear response when their cortisol levels are reduced, similar to people without PTSD. This research can help discover new medicines for people with PTSD.
Alcohol abuse and dependence (alcohol use disorders, AUDs) and posttraumatic stress disorder (PTSD) are both prevalent in Veterans. Treating AUDs in Veterans with PTSD may be more difficult than treating AUDs in the general population. The FDA-approved medication topiramate has been shown to improve drinking outcomes in people with AUDs. Topiramate has also improved symptoms in people with PTSD. This study is designed to investigate whether topiramate will improve drinking outcomes in Veterans with PTSD.
This reported observational clinical study aims at identifying epigenetic markers in a sample of patients undergoing high dose inpatient psychotherapy suffering from a variety of psychiatric/psychosomatic diseases such as somatoform disorders, posttraumatic stress disorder (PTSD), depression, anxiety disorders and eating disorders. The exact epigenetic markers that will be traced are yet to define. The investigators believe that 1. Epigenetic patterns found in the group of psychiatric patients show differences from healthy controls 2. Different diagnosis show differences in epigenetic patterns as well 3. Epigenetic patterns correlate to the severity of the psychosocial disorder as measured in interviews or psychometric ratings 4. Epigenetic patterns can change under inpatient high dose psychotherapy 5. Changes correlate to clinical psychometric variables.
The Democratic Republic of the Congo (DRC) has become synonymous with sexual violence by armed groups within the last 2 decades. Reportedly, tens of thousands of women and girls have been raped, sexually assaulted, attacked and abducted in the Eastern Provinces including North and South Kivu, targeted by armed groups with unparalleled levels of brutality. Access to services in North and South Kivu-both emergency and longer term care-remains a major challenge. Limited services as well as the potential stigma of seeking services mean that many survivors have never received adequate care. Results of a preliminary study found many survivors have substantially reduced ability to function, including reduced ability to perform basic tasks and activities related to earning, self care, caring for family, and contributing to their communities. These survivors also describe high rates of mental health and social problems including mood disorders, anxiety, withdrawal, and stigmatization and rejection by family and community. While social and economic development in conflict affected areas like DRC relies on populations who are ready and able to work, the psychological effects of conflict may mean that a percentage of the population living in these low-resource areas are less able to engage in economic opportunities even when they are available. However, there is little data on the best strategy to deal with this. This study will be run as two parallel randomized impact evaluations to investigate the impacts of two different intervention programs to be implemented as part of standard programming of the collaborating NGO. The first study will focus on the impact of IRC's social-economic intervention, Village Savings and Loans Associations (VSLA) compared to a wait-control sample. The VSLA impact evaluation study will be conducted in communities served by 9 community-based organization (CBO) partners. The second study will focus on the impact of a mental health intervention, Cognitive Processing Therapy (CPT) compared to a wait-control sample. The CPT impact evaluation study will be conducted in communities serviced by NGO partners currently providing psychosocial support. As an exploratory investigation, the researchers will follow the CPT program with the VSLA program to look at the effect of receiving a mental health intervention prior to the VSLA on rates of retention and impact.
With this research, the investigators hope to learn if cognitive behavioral therapy (CBT) for posttraumatic stress disorder (PTSD) works in people who have both PTSD and problems with drugs or alcohol. In the past, people who had problems with drugs and alcohol were not given treatment for their PTSD. It was believed that PTSD treatment would get in the way of their drug and alcohol treatment. Now the investigators believe that the PTSD symptoms may make it harder to avoid using drugs and alcohol, so the investigators want to see if people can get treatment for both problems at the same time. One hundred-sixty Veterans from 3 sites who have both PTSD and substance use disorders will be in the study. In order to know if the PTSD treatment is helpful, half of the Veterans in this study will receive PTSD treatment and half will continue to get their usual mental health and/or substance abuse treatment. Who gets which treatment will be decided by a random process. The investigators will then compare the 2 groups to see if there are differences in their PTSD symptoms.
This Phase 2 proof-of-concept study is a double-blind, randomized, placebo-controlled, 15-week investigation of ganaxolone versus placebo for the treatment of Posttraumatic Stress Disorder (PTSD). Up to 120 participants will be enrolled and randomized to receive either ganaxolone or placebo for 6 weeks. After 6 weeks of randomized treatment all participants will continue for 6 weeks on ganaxolone. The aim of the study is to assess the efficacy of ganaxolone compared to placebo for the treatment of PTSD symptoms after 6 weeks of treatment using the Clinician-Administered PTSD Rating Scale (CAPS). The second aim of the study is to evaluate the safety and tolerability of ganaxolone in the PTSD population.
The purpose of this study is to evaluate use of service dogs for individuals who have been diagnosed with Post Traumatic Stress Disorder (PTSD). Objectives include: (1) assess the impact service dogs have on the mental health and quality of life of Veterans; (2) to provide recommendations to the VA to serve as guidance in providing service dogs to Veterans; and (3) To determine cost associated with total health care utilization and mental health care utilization among Veterans with PTSD.
The goal of the study is to evaluate the efficacy of a two therapeutic models designed to enhance women's skills for managing reactive emotions in their current lives as well as to educate them about how using these skills can enhance their personal effectiveness and help them to gain control of post-traumatic stress reactions. The interventions adaptations of a manualized psychotherapy that has shown promise with adults with complex Posttraumatic Stress Disorder (PTSD) (Trauma Affect Regulation: Guide for Education and Therapy; TARGET) compared to a supportive group therapy (SGT) that has been found to have modest benefits with women survivors of childhood abuse (Wallis, 2002).
The investigators aim to assess the dental status of psychiatric patients suffering from severe mental illness (schizophrenia, bipolar disorder, ptsd, resistant depression).
