Abstract: Neuro Linguistic Programming (NLP) was created in the 70s in California. It studies in particular three components of mental and behavioral production of human experience: neurology, language and programming. Objective of the article is a review of international literature, exclusively in the field of health related to NLP. Method: we search the following keywords: NLP, PNL (Italian acronym for NLP), LEM (Lateral Eye Movements), Eye Movement, Eye Neuro Linguistic and VAKO (which, in NLP, stands for Visual, Auditory, Kinesthetic, Olfactory-Gustatory) on various search engines and in PubMed, Web of Knowledge and Scopus.Results: for the word Neuro Linguistic Programming” we identified 112 articles in PubMed, but of these, only 61 actually related to the NLP. According to the keywords, we identified 7 fields of NLP literature. These are: Communication (20 articles), Training (4 articles), Personal Well-Being (4 articles), Food and nutrition (1 article), Eye movements (8 articles), Psychotherapy (21 articles), reviews and studies on its efficacy (3 articles). Conclusions: International scientific literature is divided on NLP. We find articles against NLP, some contain methodological errors in some cases simply due to the little knowledge of NLP discipline; others are in favor of NLP but samples are too small or they are qualitative studies. It therefore remains a fascinating field to study and monitor.
