Lately, many researchers have found that Children with autism spectrum disorder (ASD) are most likely to have gross motor deficiencies such as lack of coordination in gait and balance. Much has been researched on etiology and motor learning, but only very few researches have examined and analyzed quantitatively gait and balance in ASD. The aim of this research is to analyze quantitatively balance, gait and balance during perturbation in children with ASD and to compare with typically developed children (TD). A group of 20 children diagnosed with ASD and a control group of 20 TD children will be recruited and tested in the laboratory with well-established measures of gait and balance function. They will be instructed to stand as still as possible on a force plate with different task conditions : (1) standing with the eyes open (EO) - standing upright viewing an "X" displayed on a screen 3 meters in front of them; (2) eyes closed (EC) - same as (1) with the eyes closed and covered by blindfolds (i.e. no visual information). (3) Same as 1 standing on foam (i.e., conflicting proprioceptive information). Gait will be measured using the narrow base walk test, modified for clinical use. Participants will be asked to walk within a narrow path 6 meters long . The statistical analysis will include Independent T-tests to compare the ASD and controls with respect to different characteristics. General Linear Model (GLM) will be used by applying a separate model where the dependent variables will be the average values of the postural stability or gait stability parameters (continuous) and the independent variables were categorical by the group and task condition.
The aim of this study is to assess the efficacy in PTSD treatment of concomitant voluntary reactivation of personal traumatic memories with neuromodulation of the right dorsolateral prefrontal cortex using 10Hz rTMS, compared to 1Hz rTMS, during 2 weeks.
The primary aim is to develop, and test the feasibility and efficacy of, a manual based, cognitive behaviour therapy (CBT) treatment for Hoarding Disorder (HD) delivered in a group format combined with an Internet support system. The investigators' secondary aim is to investigate the neurocognitive profile of the participants before and after treatment in order to explore if the treatment might have an impact on neurocognitive functioning and if certain neurocognitive profiles predict outcome. For the primary aim, the investigators hypothesize that the treatment will be acceptable to participants and decrease symptoms of hoarding. Regarding the secondary aim, the investigators hypothesize that deficiencies in executive functioning, as measured with a neurocognitive battery, will reduce upon completion of treatment and that baseline executive function will be associated with treatment outcome.
The purpose of this study is to determine whether the use of atypical antipsychotic medication increases the risk of hospitalization for a hyperglycemic emergency. The investigators will carry out separate population-based cohort studies using administrative health databases in eight jurisdictions in Canada and the UK. Cohort entry will be defined by the initiation of a new antipsychotic medication. Follow-up will continue until hospitalization for a hyperglycemic emergency or the end of 365 days. The results from the separate sites will be combined to provide an overall assessment of the risk of hyperglycemic emergencies among new users of various antipsychotic drugs.
Expert reviews and practice parameter papers recommend behavior therapy as a first-line intervention for youth with chronic tic disorders (CTDs) with mild-to-moderate tic severity. Although behavior therapies like the Comprehensive Behavioral Intervention for Tics (CBIT) are efficacious in reducing tic symptom severity, only 50% of individuals exhibit a positive treatment response. Thus, there is a clear need to identify strategies to improve treatment response and/or accelerate therapeutic gains . The primary ingredient of CBIT is habit reversal training (HRT), which utilizes both extinction and associative learning. Psychosocial treatments relying on these learning mechanisms have demonstrated an enhanced and/or expedited therapeutic benefit when augmented with d-cycloserine (DCS). This feasibility study will examine the incremental efficacy of HRT+DCS over HRT+placebo for tics targeted with HRT. Eligibility criteria will parallel the child CBIT trial for generalizability and comparability, with the addition of DCS contraindications as exclusionary criteria. Parents and youth will complete a battery of clinical assessments to ascertain tic symptoms severity and co-occurring psychiatric conditions. Afterwards, participants will be randomly assigned to receive either HRT+DCS or HRT+placebo. Instead of a full course of HRT (8 sessions over 10 weeks), a more efficient Quick-Win/Fast-Fail trial design will be used that includes a truncated HRT protocol to provide results in a more timely fashion. As a result of this trial design, the primary outcome of this study will focus on the reduction of bothersome tic severity for those targeted in treatment rather than global severity reductions.
This study aims to assess differences in monoamine oxidase A (MAO-A) distribution in the brain between seasonal affective disorder patients and healthy controls using positron emission tomography. In addition the investigators aim to demonstrate the impact of light therapy on MAO-A distribution In addition, a pilot study and a sub-study in healthy controls were performed
The purpose of this study is to determine the tolerability and short-term efficacy of a single ketamine infusion for the treatment of adolescents with 1) medication-refractory major depressive disorder (MDD) and/or 2) medication-refractory anxiety disorders (social anxiety disorder, panic disorder, generalized anxiety disorder and/or separation anxiety disorder).
The relationship between depression and trauma is well established. Co-occuring depression and post-traumatic stress disorder (PTSD) are associated with more severe symptoms and lower levels of functioning. Veterans with both depression and PTSD have been shown to be at much higher risk of suicide than individuals with only one of these disorders. Ketamine has been shown to have rapid antidepressant effects and also therapeutic action over PTSD symptoms. The purpose of this study is to see whether ketamine, when given as repeated infusions, can produce quick and sustained improvement in depression and PTSD symptoms for individuals who have not had their symptoms effectively treated by current treatments.
The primary objectives of this study is to test the feasibility and efficacy of group-therapy supported internet-delivered CBT for adolescents (13 - 17 years) with social anxiety disorder. Investigators will conduct an open trial with N = 30 participants. Participants will be assessed at baseline, immediately after treatment and at a 6-month follow-up.
