Filter by:Psychological treatments are effective, but take a long time and can be burdensome. Therefore, avenues to optimize behavioral treatments are needed. Despite important advancements, neuroscience has had a limited effect on psychotherapy development. Therefore, one paradigm shift would be to develop neuroscience informed behavioral treatments. The investigators identified from the literature a problem that affects several mental disorders (emotion dysregulation) and a neural circuit that underlies this important concern. They found that this circuit is dysfunctional in those with psychopathology but can be changed with treatment. The goal is in one session to train this brain network to operate more efficiently and to test the short and long term effects of this intervention. The investigators plan to engage this brain network using a traditional psychotherapy strategy (cognitive restructuring) and to enhance learning using repetitive transcranial magnetic stimulation (rTMS), a neuromodulation technique through which magnetic stimulation enhances the electrical activity in brain areas close to the scalp. The study team proposed two studies to examine this novel approach, In one of the studies 83 participants were enrolled and 47 eligible participants were divided into 3 groups. All participants were trained in emotion regulation by first being asked to remember an event where they experienced a negative emotion and then being instructed either to think differently about the event, or to wait. Participants simultaneously underwent either active (left or right side of brain) or sham rTMS. In a second study 65 participants were enrolled, and 31 were assigned to either active left or sham rTMS guided using neuroimaging results. Across both studies, the investigators measured regulation in the lab and during a-week long naturalistic assessment. Participants in the second study returned for a follow up neuroimaging visit at the end of this week. Participants returned for a one moth follow up assessment and to rate feasibility, acceptability, and provide feedback. This proof of concept set of studies demonstrated feasibility and preliminary efficacy for this approach, which opens new frontiers for neuroscience informed treatment development.
Objectives.-Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive stimulation methods that became widely used as therapeutic tools in neuropsychiatric research. The aim of this study is to Evaluate the therapeutic impact of different frequencies of repetitive transcranial stimulation (1HZ, 10HZ) in OCD patients. Material and Methods; Forty five patients of OCD were participated in the study. All patients fulfilled the diagnostic criteria of DSM-IV-TR. The mean age of the patients was 27.1+4.5 years. Each patient was subjected to the following: Yale-Brown obsessive compulsive scale (Y-BOCS), Hamilton Anxiety Rating Scale (HAM-A), and Clinical Global Impression - Severity scale (CGI-S). The patients were randomly classified into three equal groups using closed envelop: 1st group received 1 Hz rTMS at 100% of the RMT, 2nd group received 10 Hz rTMS with intensity of 100% of the RMT and 3rd group was sham group received the sham stimulation with a total 2000 pulses every day for each group for 10 sessions. Follow up of the patients using the same previous scales after the end of sessions and 3 months later.
