15 Most biological treatments in psychiatry- probably follow this path already. For example, monoamine reuptake inhibitors benefit many patients with depression by increasing serotonergic and/or noradrenergic neurotransmission, but probably not by correcting an underlying monoaminergic deficit, for which little www.selleckchem.com/products/stattic.html evidence has been found.16,17 Similarly, current lesion surgery and DBS approaches for depression or obsessive -compulsive disorder (OCD), whose targets all converge onto pathways from brain stem and basal ganglia to prefrontal cortex,18 work through—hitherto poorly understood—effects on the function of these pathways in motivation
and emotion regulation, but Inhibitors,research,lifescience,medical not necessarily- because there are documented primary abnormalities in these pathways. Regarding neurofeedback, this implies that clinical benefits may be obtained from self-regulation training that activates compensatory circuits Inhibitors,research,lifescience,medical for particular cognitive processes (eg, emotion regulation) or inhibits circuits that, although normal when viewed in isolation, contribute to dysfunction in the context of the patient’s primary pathology.
For example, it may be beneficial to suppress canonical thought processes such as self-comparison Inhibitors,research,lifescience,medical in the context of a depressive disposition. The great progress in the understanding of the circuits of cognitive, affective, and social information
processing made through the last two decades of functional Inhibitors,research,lifescience,medical imaging can thus inform the design of imaging-based clinical neurofeedback protocols, even in the absence of primarily abnormal imaging signals. Applications in depression Symptoms of depression can be broadly grouped into the four domains of emotion regulation, cognition, motivation, and homoeostasis (Table I).19 Although like all categorization of psychological phenomena, this classification is somewhat artificial (and some symptoms map onto more than one category), it can help the search Inhibitors,research,lifescience,medical for the biological mechanisms of depression.20 Furthermore if the neural systems underlying some of these functional clusters Olopatadine prove to be modifiable (by pharmacological, psychological, or physical intervention) they may become viable targets for new antidepressant therapies. Table I. Symptoms of depression. Five symptoms are required over a 2-week period for an episode of major depression (DSM-IV). ICD-10 defines depressive episodes by a combination of the most typical (printed in bold face) and other symptoms.19 The number of symptoms … New therapeutic strategies for depression are sorely needed. Depression is expected to assume the first place in the WHO’S global disease burden statistic by 2020. It affects up to 15% of the population of industrialised countries.
