[Delay of reward in borderline personality disorder: systematic literature review].

BACKGROUND AND AIM: Numerous studies report on high impulsivity and preference for "here and now" of patients suffering from Borderline Personality Disorder (BPD). In our paper, we aimed to explore and summarise those studies which explored the connection between BPD and delay discounting using empirical approach.

METHOD: In July 2010 five databases (PsycInfo, ScienceDirect, MedLine, Web of Science and PubMed) were searched using the keywords borderline, reward, "delay discount*" and "delay gratification".

RESULTS: Out of five we identified as relevant, only two studies found any difference in delaying gratification of BPDpatients compared to controls.

CONCLUSION: The analysis of results, sampling (sample size, age, fitted control) and methods (hypothetical questions)used by the studies reveal new hypotheses, and directions in this field of research.
