Introduction:

Pain can be a sequel of a stroke, and is often undervalued, limiting the patient´s quality of life. This study aimed to make a narrative review on central post stroke pain (CPSP) including its definition, prevalence, clinical presentation,

diagnosis, pathophysiology, and treatment.

Methods:

A search was performed on PubMed© looking for articles in Portuguese or English, with full text, about human research, in adults, using the terms “central” and “pain” and “post stroke”. Thirty-three articles were included in this narrative review.

Discussion:

CPSP is a neuropathic pain syndrome resulting from an insult to the central nervous system. It is characterized by pain and sensory abnormalities, such as allodynia and hyperalgesia. Prevalence varies from 5% to 50% (thalamic stroke) and it is often underdiagnosed and undertreated. Treatment includes mainly antidepressants and anticonvulsants, and a non-pharmacological approach. The surgical approach is intended for refractory cases.

Conclusion:

Management of CPSP is challenging and requires an individualized approach. Future studies may clarify CPSP´s pathophysiology, define clear diagnostic criteria, and collect evidence that allows a more effective treatment.
