Introducción: Los sujetos dependientes de sustancias presentan algunos rasgos de personalidad comunes, pero no se ha podido demostrar que la presencia de estas características determine la adicción. Se pretende analizar la actividad cerebral en un grupo de pacientes con dependencia de opiáceos más Trastorno Límite de Personalidad (TLP) o Trastorno de Personalidad No Especificado (TPNE).
Método: Se comparó una muestra de 25 sujetos con patología dual con 17 sujetos sanos. Se obtuvieron imágenes SPECT utilizando como trazador radioactivo el Tc99m-ECD por vía intravenosa. Los datos se analizaron con el paquete de software Entegra.
Resultados: Al comparar el grupo de adictos con TPNE con el grupo de control, se apreciaron diferencias estadísticamente significativas en el número de cuentas registradas en el tálamo ( =9043,26; p<0,029) lo que evidencia una menor actividad talámica en estos sujetos respecto a aquellos que no presentaban patología. No se observaron diferencias estadísticamente significativas en el resto de comparaciones.
Conclusión: Los pacientes con adicción a opiáceos y TPNE presentan un patrón de hipoactividad talámica comparados con un grupo de sujetos normales. Este hecho nos puede ayudar en el entendimiento de la etiología de estos trastornos, al menos en el subgrupo de pacientes con patología dual.

Abstract
Introduction: Patients with substance abuse show some common personality characteristics but it has not been possible to demonstrate that the presence of these characteristics determines their addiction. In the present investigation we tried to analyze cerebral activity in a group of patients with dependency on opiates and Borderline Personality Disorder (BPD) or Personality Disorder Not Otherwise Specified (PDNOS).
Method: Cross-sectional study of an observational type with descriptive and analytical components in a sample of 25 subjects with dual pathology in comparision with 17 healthy subjects. SPECT images were acquired using 99mTC-ECD (Tcm-Ethyl Cysteinate Die-thylester) by intravenous route as a radioactive tracer. Data were analyzed with the software package Entegra.
Results: When we compared subjects with PDNOS to the control group, statistically significant differences in the number of counts registered in the thalamus were noticeable ( =9043.26; p<0.029), which demonstrates less thalamic activity in PDNOS subjects with respect to healthy subjects. Statistically significant differences in the rest of comparisons between groups were not observed.93 Trastornos de personalidad y adicción a opiáceos: un estudio descriptivo Health and Addictions / Salud y Drogas 2010, Vol. 10, nº 2, pp. 91-110
Conclusion: Pacients with PDNOS and adiction show a thalamic hypoactivity pattern. This conclusion could help us in the understanding of the pathogenesis of this disorder and its differentiation from the other PD, like BPD, at least in patients with dual pathology.
