Filter by:The study of immune pathways involved in the etiopathogeny of schizophrenia would be an important advance to understand the mechanisms involved in the development of this disease and it would be a turning point in drug therapy. Until now, the mechanism of action of antipsychotics focused on the blockade or modulation of brain dopaminergic pathways. If immunological pathways responsible for neuroinflammation and neurodegeneration which involve alterations in different areas and brain pathways (including dopaminergic pathways) are discovered, investigators could develop new treatments that act on these new targets, allowing to delay the onset of the first psychotic episode and improve the evolution and impact of this disease.
Case-control comparison of clinical population, interventional and single-center research.

Schizophrenia is a severe psychiatric disorder that affects approximately 1% of the population worldwide. Although pathophysiology of this disease remains unclear, a growing interest is emerging for low-level sensory function, acknowledging that deficits in early stages of sensory processing are related to higher-order cognitive disturbances in schizophrenia. In the field of auditory processing, symptoms as auditory-hallucinations were found correlated with disabilities to discriminate psychoacoustic parameters of sounds.
Schizophrenia is a severe mental illness associated with excess mortality and affecting nearly 1% of the population. The average life expectancy for patients diagnosed with schizophrenia has been 55-60 years through the last generations in Denmark, while the general population has over the same period of time experienced an increase in life expectancy. As a result, the standardized mortality rate for patients with schizophrenia has increased markedly over the last three decades and is currently a major public health concern. Causes of death are mainly cardiovascular disease and patients diagnosed with schizophrenia has a relative risk of cardiovascular disease that is about 2-fold higher than the general population.
As in the general population, there is a gradual and steady increase in life expectancy of patients with schizophrenia. But this increase is at a smaller scale, with a rate of premature death that is still 2 to 3 times higher than that found in the general population. This excessive early mortality is explained by an overrepresentation of suicide deaths, but also a higher prevalence of somatic diseases, mainly cardiovascular. But today there are only very few epidemiological data on the mortality of patients with schizophrenia, including those aged over 60 years. What are the sociodemographic and clinical characteristics (psychiatric and somatic) of these schizophrenic elderly patients? Do they benefit from a somatic follow-up adequate and systematic? What are their levels of social independence and of quality of life? the answers these questions and the description of the offer of geriatric care and of psychiatric care currently provided by different sectors of psychiatry in France is an indispensable prerequisite for any project to improve the quality of life, state of health and mortality of older patients with schizophrenia.
The purpose of this study is to determine whether dopamine synthesis capacity by using [18 fluorine(F)]-DOPA PET for patients with schizophrenia in the maintenance phase can predict treatment discontinuation.
The investigators propose to study the brain processes that result in thought and language disorder and influence outcomes seen in patients with schizophrenia using a combination of brain scans and clinical assessments. The project will assess patients at various stages of psychosis (Clinical high risk, first episode and chronic stage >3 years of illness) referred to the Prevention and Early Intervention in Psychosis Programme using Magnetic Resonance Imaging (MRI scans). To track the outcome of this illness, investigators will follow-up patients over 3 years and collect MRI scans over four sessions for each first episode patient, and two sessions for clinical high risk patients, chronic patients, and healthy controls. Participants will also complete a clinical assessment examining symptoms and functioning as per the current clinical practice within the PEPP program at each scanning session.
The first purpose of this study is to determine if dopamine synthesis capacity is significantly lower in treatment non-responders from illness onset relative to treatment responders. And the second purpose of this study is to determine the potential of [18 fluorine(F)]-DOPA to be used to predict treatment response to antipsychotic treatment in first episode psychosis.
The goal of the study is to investigate whether adding different doses of sulforaphane will benefit the clinical symptoms and cognitive function in individuals who have schizophrenia. This study will compare the sulforaphane with placebo. There is a thirty percent change (less than half) of receiving the placebo. The purpose of including placebo is to judge if the outcome is related to the study medication rather than other reasons.
