Active clinical trials for "Mental Disorders"

This is an exploratory clinical investigation. The objectives of this study are to evaluate the safety, steady-state pharmacokinetics, and efficacy of metyrosine (Demser®) for the treatment of psychosis in patients with velocardiofacial syndrome (VCFS).

Parkinson's disease (PD) is the second most common neurodegenerative disorder of the elderly that affects a million patients in US. Sleep dysfunction impacts up to 90% of PD patients. PD patients experience a variety of sleep disorders including parasomnias, specifically REM behavior disorder (RBD) that can precede the onset of motor manifestations of PD. RBD has negative consequences on patients' and their bed partners' quality of life mainly due to its impact on the sleep quality and day time alertness. RBD also predisposes affected individuals and their bed partners to physical injuries. There are no FDA approved treatments for RBD. Clonazepam is the most commonly used treatment but carries risks of daytime sedation, tolerance, and withdrawal symptoms. More recently, melatonin has been demonstrated to be effective in several small studies. Ramelteon, a selective melatonin receptor agonist with favorable safety profile, could potentially be effective for the treatment of RBD. This pilot protocol will investigate safety and efficacy of ramelteon for the treatment of RBD in subjects with parkinsonism. We plan to recruit 20 subjects with RBD diagnosed based on the clinical interview and confirmed by the polysomnographic (PSG) data. The study is designed as a prospective randomized placebo controlled 12-week study. Primary outcome measure will be change in frequency of RBD events based on the daily sleep diaries. Secondary outcome measure will be change in the amount of tonic muscle activity based on the results of the baseline and final PSG. A number of other secondary and exploratory outcome measures will be collected

The purpose of this study is to determine the safety and efficacy of risperidone monotherapy in the treatment of psychotic depression. We hypothesize that risperidone is as equally as effective as haloperidol plus sertraline for depression with psychotic features

This project evaluates mindfulness based stress-reduction (MBSR), adjusted and manualized for intellectually able autistic adults. MBSR is a skills training program based on further development of cognitive behavioral therapy. The program includes eight weekly group training sessions and one full-day retreat, aiming at stress reduction and improved coping in everyday life, as well as improved mental health. The aspiration is to make ASD-adjusted MBSR an intervention that is acceptable and accessible to individuals with autism in open clinical care. This includes considering variability in background factors such as age, comorbidity and other personal qualities and preferences. The aim of the studies is to evaluate (1) the feasibility and (2) effectiveness of MBSR in adults (18 or over) with autism without intellectual disability, in an outpatient clinical habilitation context.

This will be an observational study looking at clinical and biomarker characteristics in patients with Parkinson's Disease (PD), Multiple System Atrophy (MSA), Rapid Eye Movement Sleep Behavior Disorder (RBD), Normal Pressure Hydrocephalus and matched controls. Saliva, plasma, serum, urine, and cerebrospinal fluid (CSF) samples will be collected from participants.

The primary aim of the project is to test the effectiveness of a cognitive remediation treatment (CRT) program, My Brain Solutions (MBS), in addition to motivational interviewing (MI) in improving cognition and functional outcome of individuals at risk of SMI. An active control treatment consisting of CRT alone will be used. Hypotheses: 1. Both study groups will have improvement in cognition at the end of treatment; 2. CRT+MI group will have increased treatment adherence and superior improvements in cognition at the end of treatment and 12 months post baseline compared to the CRT only group; Secondary Hypothesis: 3. Improved cognition will be associated with improved functional outcome.

The overall purpose of this study is to determine whether a family history of psychosis is associated with an altered cannabinoid system. This will be tested by studying individuals with and without a family history of psychosis and comparing their responses to delta 9-tetrahydrocannabinol (THC), a probe of the cannabinoid system. We hypothesize, that compared to controls with no family history of psychoses, individuals with a family history of psychoses will have an altered response to THC.

We will conduct a randomized control trial to investigate whether and to what extent regular and guided group physical activity over 12 weeks (2 sessions à 1 hour/week) improves physical fitness and (physio-)psychological functions (like subjective sleep, mental toughness, perceived stress, self-efficacy, etc.), as well as participation skills and the ability to work, in claimants for a disability pension due to psychiatric disorders, whose ability to work had recently been assessed by means of a psychiatric expert opinion. The control group is designed very similar and implies predominantly sedentary leisure time group activities (e.g. playing board games, doing handicrafts). Measures will be performed at baseline, post-test, and at follow ups three and twelve months after post-test, some variables will additionally be assessed 4-weekly during the intervention. We expect that intervention group participants will report and show, respectively, more improved physical fitness, (physio-)psychological functioning and participations skills, as well as increased ability to work, compared to the control group.

Alzheimer's disease (AD) is the most common cause of dementia and currently has no disease modifying treatments or simple accurate diagnostic tests. The goal of this project is to study how tau (a protein thought to cause AD) is made, transported and cleared in the human body. Better understanding of these processes may lead to improved understanding of AD, earlier diagnosis and a way to evaluate treatment.

The general objectives of this study are to build a proof-of-concept, speech-based, digital biomarker for identifying the presence and tracking the severity of psychiatric disease.
