Due to the nature of these abnormalities, it was concludedthat possibly the main dysfunction for this disorder waslocated in the right hemisphere, especially in the frontal cortex;nevertheless this particular brain region was found to be involvedin other psychiatric disorders, so neuropsychological results wereconsidered to be of limited precision and it was thought that thediversity in results was not due to the malfunction of one particularbrain region.So it became evident that a new research methodology based inthe information processing model with highly specific neuropsychologicalparadigms of frontal functioning was needed; as wellas considering a subtypology based in the cognitive characteristicsin patients with the same disorder and similar phenomenology.Regarding OCD it is well known that the dorsolateral prefrontalcortex is in charge of the regulation of complex actions, executivefunctions and the elaboration of logical strategies in a problemsolving task; so its dysfunction causes a failure in the creationof response patterns and perseverations due to the inability tochange a pattern when an alternative response is needed.On the other hand, obsessions are associated mainly with theanterior cingulated cortex and the basal region of the corpus striatumand its connections with the limbic system, giving place toincapacity to select the relevant information from the environment,which makes the individual perceive irrelevant stimuli asthreatening for physical integrity. 2007 artículo científico 0185-3325 https://www.redalyc.org/articulo.oa?id=58230101 en http://www.redalyc.org/revista.oa?id=582 Salud Mental application/pdf Instituto Nacional de Psiquiatría Ramón de la Fuente Muñiz Salud Mental (México) Num.1 Vol.30 |
