Factors Influencing Cognitive Impairment in Neuropathic and Musculoskeletal Pain and Fibromyalgia. Pain Med. 2018 Mar 1;19(3):499-510http://hdl.handle.net/10668/11001To assess cognitive performance of chronic pain (CP) patients diagnosed with three types of pain-neuropathic pain (NP), musculoskeletal (MSK), and fibromyalgia (FM)-and to analyze the factors influencing cognitive difficulties in each group. Two hundred fifty-four CP patients-104 NP, 99 MSK, 51 FM-and 72 pain-free subjects were included in the study. The "Test Your Memory" (TYM) scale was used to assess cognitive performance. Pain intensity was measured by means of the visual analog scale (VAS); the Hospital Anxiety and Depression scale was used to assess mental status, and the Medical Outcome Study (MOS) sleep scale to assess sleep quality. The relationships between cognitive performance and these factors were analyzed using linear regression models. The mean score in the TYM was significantly lower (worse cognitive function) in CP patients than controls (40.5 vs 43.9, P These results highlight the importance of taking into account the type of pain when assessing cognitive performance in CP patients and demonstrate the influence of the emotional state of the patient, especially if depression is present.enChronic painCognitive functionAnxietyDepressionSleepAdolescentAdultChronic PainCognitionCognitive DysfunctionFemaleFibromyalgiaHumansMaleMiddle AgedMusculoskeletal PainNeuralgiaYoung Adultresearch article28340167open accessCogniciónDisfunción cognitivaDolor crónicoDolor musculoesqueléticoFibromialgiaNeuralgiaPersona de mediana edad10.1093/pm/pnx0241526-4637https://academic.oup.com/painmedicine/article-pdf/19/3/499/24374443/pnx024.pdf
