RESUMEN
Se reportan los hallazgos encontrados a partir de NeuroSPECT en trastornos del ánimo, incluyendo trastorno bipolar, depresión mayor y auto-mutilación. Se compararon los resultados de una muestra de 29 pacientes con trastorno afectivo en espectro bipolar complicado con conductas auto-mutilatorias, un grupo de 20 pacientes bipolares sin auto-mutilación y 22 pacientes depresivos sin auto-mutilación. Dentro de los hallazgos destaca la asociación entre trastornos del ánimo y auto-mutilación con hiper-perfusión talámica bilateral en el segmento dorso-ventral-anterior, asociado a hipo-perfusión en corteza peri-límbica (áreas 32, 24 y 23 de Brodmann). Los múltiples reportes que relacionan, tanto en animales como en humanos, las conductas auto-mutilatorias con fenómenos de hipo-algesia, anestesia o disestesias, permiten hipotetizar la participación de una disfunción en circuitos tálamo-peri-límbicos asociados a vías nocioceptivas y a conciencia somato-psíquica y su relación con fenómenos auto-mutilatorios.
ABSTRACT
We report NeuroSPECT findings in mood disorders, including bipolar disorder, major depression and self-mutilation. We compare results in 29 patients with bipolar disorder complicated by self-mutilation, a group of 20 patients with bipolar disorder uncomplicated and 22 patients with mayor depression uncomplicated by self-mutilation. Among the NeuroSPECT findings we report the association of mood disorders and self-mutilation with hyperperfusion of the anterior-dorsal-ventral segment of both thalami concomitant with hypoperfusion in perilimbic cortex, namely areas 32, 24 (anterior cingulate gyrus) and 23 of Brodmann. Multiple reports in the literature relate both, in animals and man, self-mutilation with phenomena of hypoalghesia, anesthesia, or dysestesias and are the basis for our hypothesis linking dysfunction of limbic-thalamic circuits, associated with nocioceptive fibers, somato-psychic consciousness and self-mutilation phenomena.
