Treatment of Psychosis and Agitation in Alzheimer's Disease
Alzheimer's DiseasePsychosis1 moreClinically, many patients with AD show no response or minimal response to antipsychotics for symptoms of agitation/aggression or psychosis, or they have intolerable side effects on these medications. Antipsychotics have a wide range of side effects, including the risk of increased mortality (60-70% higher rate of death on antipsychotic compared to placebo) that led to an FDA black box warning for patients with dementia; a more recent review and meta-analysis showed a 54% increased risk of mortality. In addition, some patients show only partial response to antipsychotics and symptoms persist. For these reasons, the investigators need to study alternative treatment strategies. Currently, there is no FDA-approved medication for the treatment of psychosis or agitation in AD. The investigators innovative project will examine the efficacy and side effects of low dose lithium treatment of agitation/aggression with or without psychosis in 80 patients with AD in a randomized, doubleblind, placebo-controlled, 12-week trial (essentially a Phase II trial). The results will determine the potential for a large-scale clinical trial (Phase III) to establish the utility of lithium in these patients.
Integrated Metacognitive Therapy in First Episode Psychosis
SchizophreniaSchizophreniform Disorder1 moreInsight, or lack of illness awareness, is a prominent and pressing clinical concern in the treatment and recovery of patients with psychotic disorders. Impaired insight results in poor treatment engagement and adherence, more frequent hospitalizations, greater positive and negative symptoms, and poor psychosocial functioning. Addressing these complications early in the disease process may lead to altered illness course with better outcomes. To date, only a small number of nonpharmacological interventions have been developed, none of which adequately address poor insight during the first few years of psychotic illness. Further, presently available therapeutic interventions do not attend to difficulties associated with improved insight, such as depression. The purpose of this investigation is to implement a novel intervention designed to improve insight, metacognition, neurocognition, symptoms, and ultimately overall functioning in persons with early psychosis. The novel intervention will integrate a number of previously established therapeutic approaches, such as metacognitive, narrative, cognitive behavioral and motivational interviewing, and hence be labeled Integrated Metacognitive Therapy (IMT). In order to measure the efficacy of IMT, all subjects will undergo a battery of assessments in each of these domains prior to and following either a novel intervention (N = 10) or treatment as usual (N = 10) for a period of approximately six months. Throughout the study, each IMT session (N = 10, 24 sessions each) will be audio recorded, transcribed, and de-identified to allow for careful ongoing qualitative analyses of potential active and inert ingredients of the approach and ultimately the development of an IMT manual which can then be tested in a larger, more rigorous randomized control trial. This investigation will play an important role in advancing current knowledge about treating insight in early psychosis. Further, it will serve to expand upon the intervention tools available by producing a much needed treatment manual designed specifically to target insight during an illness phase crucial for positive long term outcomes in psychosis.
Interventions to Improve Functional Outcome and Persistent Symptoms in Schizophrenia
SchizophreniaSchizoaffective DisorderMany individuals with schizophrenia continue to hear voices, have false beliefs, and problems with attention, memory planning and everyday functioning even with medication treatment. The process of recovery in schizophrenia involves treating the whole person. This study will test a new Multimodal Cognitive Treatment (Mcog). Mcog works around problems in attention, memory and planning by using supports in the home such as signs, checklists, and alarms to improve everyday functioning. Mcog also helps the individual to examine the evidence for their beliefs and to deal with symptoms like voices that are not completely resolved with medications. We will compare 4 treatments to determine if this combined approach improves both symptoms and functioning for individuals with schizophrenia.
Social Cognition Intervention
PsychosisVeterans with schizophrenia and schizoaffective disorder experience high levels of disability and poor community outcome, and these poor functional outcomes constitute a major public health concern. The treatment of schizophrenia spectrum disorders has shifted fundamentally from a focus on symptom reduction to a focus on recovery and improving aspects of functioning. Needed improvements in community outcome for patients with these disorders will not occur simply through better control of clinical symptoms. Instead, it is necessary to find new treatments that address the key determinants of poor functional outcome, including social cognition. Both basic (non-social) cognition and social cognition are considered key determinants of functional outcome for schizophrenia and schizoaffective disorder. Basic cognition includes the domains of: learning and memory, vigilance / attention, speed of processing, reasoning and problem solving, and working memory. Social cognition generally refers to mental operations that underlie social interactions, including perceiving, interpreting, managing, and generating responses to socially relevant stimuli, including the intentions and behaviors of others. As part of the investigators' previous Merit grant, they have developed a training program for social cognition and are in the process of validating it. Initial results suggest that the program improves performance on measures of social cognition and functional capacity. In this study, the investigators will evaluate whether adding an in vivo component (training activities that occur in the community) to the current social cognition intervention facilitates generalization of training effects to community outcome and subjective satisfaction. Outcome measures of social cognition and functional capacity will be examined during the 12 week training program, and durability of benefits will be assessed at a 3-month follow up. Generalization to community functioning and subjective satisfaction will be assessed at the end of training and at the 3-month follow up. The investigators will enroll 105 patients across the 5 years of the study with random assignment to training group (social cognition intervention with in vivo exercises, social cognition intervention without in vivo exercises and control). Subjects will receive assessments at baseline, 6 weeks (mid-point), completion of training (12 weeks), and the 3-month follow up.
Glycine to Treat Psychotic Disorders in Children
Psychotic DisorderSchizoaffecitve Disorder1 moreThis study will test the safety and effectiveness of the amino acid glycine in treating psychotic disorders in children. The drug will be given as an adjunct (in addition) to the patient's current antipsychotic medication. Children age nine to 18 with schizophrenia or schizoaffective disorder whose symptoms began before age 13 may be eligible for this 10-week study. Patients will be hospitalized during the course of the trial. Weekend visits home may be permitted. Children enrolled in the study will be evaluated during a two-week pre-treatment period with written tests for IQ and academic functioning and with a magnetic resonance imaging (MRI) scan of the brain. For the MRI, the child lies on a table that slides into a large donut-shaped machine with a strong magnetic field. This procedure produces images of the brain that may help identify brain abnormalities in schizophrenia that develop in childhood. During the eight-week treatment phase, patients will receive glycine powder dissolved in water once a day, in addition to their other antipsychotic medications. They will undergo the following additional procedures during the course of treatment: Comprehensive psychiatric examination Blood pressure and pulse monitoring once a week Blood tests every other week - About one ounce of blood is drawn per week to measure glycine levels Eye movement study at week eight - Using a technique called infrared oculography, special detectors measure infrared light reflected off the child's eyes while he or she watches a moving square on a video monitor. Lumbar puncture (spinal tap) once during the study - About one-half ounce of cerebrospinal fluid (the fluid surrounding the brain and spinal cord) is withdrawn through a needle placed in the lower part of the spine for analysis of brain chemicals. Patients who respond well may continue to receive glycine treatment through their referring physician after the study is completed. NIMH will follow patients by phone every six months and with visits at two-year intervals.

Modafinil for Treatment of Cognitive Dysfunction in Schizophrenia
SchizophreniaSchizoaffective DisorderPatients with schizophrenia have problems in thinking, known as cognitive dysfunction. This appears to be responsible for their difficulties in social and occupational functioning. One particular cognitive function that may be important for schizophrenia is called context processing. This refers to the ability to properly use information in the environment to guide thinking and behavior so that it is appropriate to the present circumstance. Problems with this function may explain why patients with schizophrenia think and act in unusual ways, and often have problems managing aspects of their lives that healthy adults take for granted. This cognitive function depends on a region of the brain called the prefrontal cortex, which shows impaired function in schizophrenia as well. Unfortunately, the biochemical aspects of this dysfunction are presently unknown, and it is not clear whether current psychiatric medications can improve this function. A recent FDA-approved medication that may improve this function is modafinil. Studies in animals and healthy adults show that this medication can improve cognitive functions which are related to context processing. We plan to study the effects of modafinil on context processing and the brain activity that underlies this function. We will use functional MRI and electrophysiology to examine the effects of modafinil, both after a single dose and after sustained (4 week) treatment. We predict that when patients receive modafinil they will perform better on cognitive tests and have improved activity in the regions of the brain that are responsible for these cognitive processes.
Effects of Pentazocine Versus Lorazepam on Manic Symptoms
Bipolar DisorderSchizoaffective Disorder3 morePilot data indicates that pentazocine decreases manic symptoms in hospitalized individuals. To follow up these initial findings, we plan to conduct a larger, more rigorous, double-blind study. We will examine whether pentazocine, an agent with kappa-opiate activity, decreases manic symptoms.
Treatment of Schizophrenia With an Omega-3 Fatty Acid (EPA) and Antioxidants
SchizophreniaSchizophreniform Disorders2 moreThe purpose of this trial is to study the effect of adding the omega-3 fatty acid EPA and/or Vitamins E + C to antipsychotic drugs in younger patients with schizophrenia and related psychoses.
