OBJECTIVE

Dysphagia is common after stroke and represents a marker of poor prognosis. After ischemic stroke, dysphagia represents only one part of the clinical spectrum of changes in the gastrointestinal (GI) tract and includes GI hemorrhage, delayed GI emptying, and colorectal dysfunction. State-of-the-art imaging techniques have started to revolutionize to study the cortical and brainstem control of these GI symptoms. It has become increasingly obvious that GI alterations after stroke are complex and its recovery following stroke is even more so.

METHODS

In this review, an electronic database research was performed in MEDLINE, EMBASE, and the COCHRAINE database using the terms stroke, dysphagia, GI motility, or cortical reorganization; an extensive manual searching was additionally conducted.

RESULTS

Cerebral ischemia may lead to an interruption of the axis between central nervous system and GI …
