Background
Chronic primary musculoskeletal pain (CPMP) is a recently defined diagnosis that is characterized by persistent pain alongside emotional distress and/or functional disability. Individuals suffering from chronic pain often experience sleep disturbances and cognitive complaints, highlighting a potential association that warrants further exploration. Despite this, research specifically examining the interplay of sleep quality and cognitive performance in CPMP is limited. This observational study aims to investigate the impact of sleep quality on cognitive functioning in individuals diagnosed with CPMP, assessing its contribution to various cognitive domains pertinent to the neuropsychological profile of this condition.
