Filter by:This project proposed to demonstrate the effectiveness, costs, and benefits to participation and community living self-directed care programming within a financially sustainable Medicaid managed care environment. The study examined outcomes associated with the implementation of a novel self-directed care (SDC) approach being implemented in Delaware County, Pennsylvania in which consumers were able to access a set amount of renewable funds per year and direct how they were spent, both to purchase the types and amounts of rehabilitation and treatment services they desire (and from whom they choose) and to purchase a broad-range of individualized resources and services that are generally outside of Medicaid funding (e.g., health club memberships, yoga classes, support in taking care of bills).
Fifteen minutes is the typical length of an outpatient medication management appointment for people with serious mental health conditions. These brief interactions with prescribers are frequently provider-driven with insufficient time focused on the patient's needs and personal recovery. Shared decision making is a strategy that could improve this interaction. This study examines how technology can be used in the care process to amplify the voice of the patient, support shared decisions, and improve treatment outcomes. Investigators will compare the effectiveness of Measurement-Based vs. Person-Centered Care on two primary patient-centered outcomes: the patient experience of care with medication treatment and the level of shared decision making. Investigators hypothesize that: 1. Person-Centered Care will result in greater improvement in patient experience of care with medication treatment than Measurement-Based Care. 2. Person-Centered Care will result in a greater level of shared decision making during the medication visit than Measurement-Based Care. The study team will collect information from patients, caregivers, and clinic staff at different points in time during the study. Patients will be asked to complete questionnaires, and additional data on their service use will be gathered. Some patients and providers will also be interviewed about their experiences with care. Investigators are especially interested to learn if and how these two approaches are perceived to change medication treatment, if patients are more satisfied and empowered in their care, and why and how providers perceive and adopt changes to their clinical care.
The purpose of this study is to attempt to treat cognitive and negative symptoms of schizophrenia, with the nutritional supplement N-acetylcysteine (NAC). Schizophrenia is a chronic mental disorder that affects approximately 65 million people worldwide, and causes significant disability and suffering. Patients with schizophrenia often hear voices and have persecutory delusions. Though these are the most recognizable features of the illness, the deficits most closely linked to disability are known as cognitive deficits and negative symptoms. Cognitive abilities refer to the ability to perform mental tasks that require focus and attention, and also include memory and verbal skills. Negative symptoms refer to a lack of interest in the world, and decreased social interactions. In our study, the investigators aim to improve these symptoms and deficits by targeting the glutamate system. Glutamate is the major excitatory neurotransmitter in the brain, and its regulation is abnormal in schizophrenia: glutamate levels are too low at some receptors, and too high at others. As well, free radicals surrounding glutamate receptors also interfere with their proper function. N-acetylcystine (NAC) is a safe and widely-available dietary supplement that may restore glutamate to its correct levels in the brain, and may also help protect the brain from antioxidant damage. In our study, patients with schizophrenia will be randomly assigned to receive either NAC or placebo for 8 weeks. Brain levels of glutamate and an important antioxidant, glutathione, will be measured before and after treatment, using a neuroimaging technique known as magnetic resonance spectroscopy. Cognitive and negative symptoms will also be assessed before, during and after treatment. The investigators hypothesize that glutamate and glutathione will be normalized in patients' brains, and that their negative and cognitive symptoms will be improved, too.
The purpose of this study is to find out the time it takes to absorb, distribute, breakdown and remove the drug from the body in healthy participants and subjects with schizophrenia and whether it causes any side effects.
Cannabidiol (CBD) is a component of herbal cannabis that is present in varying concentrations in cannabis extracts. CBD has been shown to produce central effects including hypnotic, anticonvulsive, anxiolytic and neuroprotective effects.The investigators hypothesize that treatment with CBD will result in: 1) Improvement evidenced by a reduction in scores on the Positive and Negative Syndrome Scale for Schizophrenia (PANSS), 2) Improvement evidenced by a reduction in the Clinical Global Impression of Severity scale (CGI); Secondary Hypothesis: 1) Greater improvement in functioning as measured on the "Patient Assessment of Own Functioning Inventory: (PAOFI) and the Quality of Life Scale (QLS) In this 2 period cross over design, subjects will be randomized in a 1:1 ratio to receive either: Order 1: CBD (Period 1) followed by placebo (Period 2) or Order 2: Placebo (Period 1) followed by CBD (Period 2) under double-blind conditions. The 2 study periods will be separated by a washout of at least 2 weeks. During each period subjects will receive study medications (CBD [total 800mg/day] or placebo) for a period of 4 weeks.
The purpose of this study is to compare the rate and extent of absorption of Aripiprazole Oral Soluble Film 10 mg (Test) versus Abilify® 10 mg tablet (Reference) in healthy male volunteers
This study will evaluate the effect of 8 doses of intranasal oxytocin or placebo on two proposed measures of target engagement in brain. The targets are (1) the suppression of a particular wave form (mu) on the electroencephalogram (EEG) while subjects observe a socially relevant form of motion and (2) pupil dilation will subjects identify faces showing different emotions.
PPI is an objective measure to assess pre-attentive processes that have already been tested before in the case of schizophrenia. The investigators aim to assess through this instrument two main characteristics, that the investigators assume are of relevance which are the duration of illness and the type of pharmaceutical treatment, patients receive. The investigators believe these two main characteristics are critical to the ability of the patients in improvement of their PPI response to startle reflex.
Schizophrenia is associated with a wide range of symptoms impacting a number of different domains, including cognitive impairment. Given the array of cognitive deficits associated with schizophrenia and their relationship to daily functioning, numerous research groups have examined the impact of cognitive remediation on many aspects of cognition. However, it is currently unclear as to which domains of cognition should be targeted to produce the most widespread and durable benefits for schizophrenia patients. It may be the case that targeting lower-level cognitive processes that are important for higher-level and more complex aspects of cognition may produce the most widespread benefits in cognition and everyday functioning. Relatively few studies have examined the effects of working memory or processing speed training on individuals with schizophrenia, as most studies examine broad-based remediation programs. Thus, there is a need for targeted working memory and processing speed training studies to better understand the mechanisms of cognitive enhancement through training in patients. This study will aim to: 1) investigate near-transfer gains associated with working memory and processing speed training in schizophrenia patients, 2) investigate far-transfer gains associated with working memory and processing speed training (i.e., gains in other neurocognitive domains and social cognition), and 3) investigate real-world gains associated with training (i.e., gains in daily functioning). Towards this aim, 81 schizophrenia patients will be recruited and randomly assigned to a working memory training group, a processing speed training group, or a no training control group. Training will be completed at home for 30 minutes per day, 5 days per week, for a total of 10 weeks. Neurocognitive, social cognitive, and daily functioning measures will be administered both pre- and post-training to detect training-related gains.
The objectives of this 12-week study are to evaluate the efficacy, safety, and tolerability of AVP-786 as an adjunctive treatment compared with placebo in patients with residual schizophrenia.
