Filter by:This study will examine the differential relationships between antipsychotic efficacy and changes in dopaminergic and glutamatergic brain metabolism in lumateperone and risperidone treated early psychosis patients. Baseline glutamate and dopamine brain scans, and symptom severity measures will be collected, followed by repeated measures at 6 weeks. Half of the early psychosis patients will be treated with lumateperone, half with risperidone. Healthy control subejcts will also be examined once.
The study is a combined clinical patient outcome study and a health-services research sub-study. Illness management and recovery (IMR) constitutes an evidence-based practice with 11 modules focusing on personal recovery developed for adults with severe mental health illnesses. IMR can be offered in groups or individually, once a week for 10-12 months. Little is known about how young people experience the utility of IMR treatment groups in child and adolescent mental health outpatient clinics. The primary aim is to explore in-depth how the participants experience the utility of the IMR approach. The health research sub-study will provide new insights into the IMR implementation process in outpatient clinics for adolescents.
The pandemic of coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has lately caused worldwide health problems. Patients suffering from a severe mental disorder are at increased risk for infectious diseases. The primary aim of the present surveillance study is to perform COVID-19 serological testing on patients with a diagnosis of schizophrenia, schizoaffective disorder or a bipolar affective disorder. Patients from the catchment area of the Capital Region of Denmark will be COVID-19 tested at baseline (0 months) and again at 6 and 12 months, in order to follow the spread of COVID-19 among this vulnerable patient population.
The purpose of this study is to demonstrate an association between a biological pattern of dysregulation of the HPA axis and mental disorders in children exposed to early life stress.
The purpose of this study is to test whether administration of levetiracetam (LEV), a commonly used anti-epileptic that alters neurotransmitter release, can reduce hippocampal hyperactivity. Specifically, we will utilize two functional magnetic resonance imaging (MRI) techniques: 1) blood oxygen level dependence (BOLD) contrast will assess activity with a visual scene processing task that engages the anterior hippocampus and 2) arterial spin labeling (ASL) will assess baseline activity. This study will also assess whether patients have improvement in their symptoms after receiving LEV. Previous studies in people with psychotic disorders have shown that the hippocampus is hyperactive and more activity correlates with worsening of clinical symptoms. Therefore, the aim of this study is to use an intervention to further understand the underlying mechanisms of the hippocampus in psychosis.
The purpose of this study is to address the shortcoming in clinical hallucination research by causally manipulating the neural loci of conditioned hallucination task behavior in-person in patients with psychosis using transcranial magnetic stimulation (TMS), tracking the impact of this manipulation on the number of times participants with hallucinations report hearing tones that were not presented. With such a causal intervention, the veracity of this explanation of hallucinations will be either validated or disconfirmed. If validated, the task can be further developed as a biomarker for predicting the hallucination onset, guiding, developing or tracking the effects of treatments for hallucinations.
This 12-month study will evaluate the efficacy of aripiprazole lauroxil compared to oral aripiprazole in preventing the re-emergence of psychotic symptoms in patients with a recent onset of schizophrenia.
In psychotic disorders, negative symptoms and cognitive impairment are difficult to treat with antipsychotics, which are mostly effective for positive symptoms. However, it is important that negative symptoms and cognitive impairment are treated as well, as they both play a large part in the acute episode and long-term course of schizophrenia outcome. Previous studies have used D-serine as add-on treatment in patients with psy-chotic disorders and high-risk patients, with positive results. So far, no study has investigated the effects in a sample of recent-onset psychosis patients. Therefore, this study will include 30 patients (18-50 years old) with recent-onset psychosis. In addition to their regular treatment, patients will receive either D-serine (2 g/d) or placebo for 6 weeks. D-serine is an amino-acid naturally occurring in the brain which is prescription-free available as nutritional supplement. The primary outcome measure is total score on the Positive and Negative Syndrome Scale (PANSS). Secondary measure-ments include PANSS subscales, neurocognitive tests, (f)MRI, and EEG
This study will determine whether targeted cognitive training, a low-cost and low-risk commercial cognitive remediation therapy, directly impacts therapeutic targets as well as secondary outcomes in college undergraduates. The active intervention will be compared to an active control condition (computer games). Participants will also attend CSU TILT (The Institute for Teaching and Learning) Academic Workshops.
This study is a 4-week pilot study for subjects with Schizophrenia or Schizoaffective Disorder who have not experienced a significant relief of symptoms from current anti-psychotic medication. The Investigators hypothesize that 4 weeks of telmisartan at 80mg daily will alter blood biomarkers for inflammation and oxidative stress after 4 weeks treatment.
