View clinical trials related to Schizophrenia; Negative Type.
Filter by:Schizophrenia is a complex, challenging, and heterogeneous psychiatric condition, affecting up to 0.5% of the population and responsible for nearly 2% of all Canadian health-care expenditure. Much of the morbidity of the illness is related to its negative symptoms, including amotivation, asociality, anhedonia and flattened emotional affect, which lead to functional impairment and withdrawal from social and occupational domains. In contrast to positive symptoms, such as hallucinations and delusions, there are currently no effective treatments for negative symptoms, which experts recognize are largely responsible for the long-term disability of a majority of patients with schizophrenia. Advances in neuroscience have allowed a greater understanding of negative symptoms and have identified key structures and circuits believed to generate and maintain them. Here, we propose the application of a targeted therapy, deep brain stimulation, to alter the circuits driving negative symptoms.
