Mood and sleep disorders in relation with cognitive deficits in patients with chronic pain. A non-coincidental relationship. Inmaculada Failde1, Begoña Ojeda1, Alejandro Salazar1, María Dueñas1, Juan Antonio Mico2.
The association between pain and affective disorders is complex. Therefore, it is necessary to know other factors that may affect this relationship.
In the present study we explored the effect of cognitive function and quality of sleep on affective disorder in chronic pain patients.

Having a sleep disorder, a previous diagnosis of depression and impaired cognitive function were associated with worse results on the HADS scale.
Chronic Pain
Sleep and cognitive function disorders are common in patients with chronic pain and represent factors that have a greater impact than the pain itself on their mental health.
