Prognostic factors for recovery of aphasia after acute ischemic stroke—a review

Abstract

Introduction : Stroke, as defined by the World Health Organization, is the rapid development of clinical signs of focal brain dysfunction lasting more than 24 hours or leading to death for no reason other than vascular origin. Subarachnoid hemorrhage is not included. Aphasia is a common symptom of stroke. The improvement of aphasia takes place mainly within the first 3 months. The four main components of the classical aphasic syndrome are: comprehension, repetition, naming, and fluency. Understanding usually indicates earlier and complete recovery and is essential for basic communication. Nevertheless, persistent, albeit less pronounced, impaired communication ability remains a major problem for the individual patient with aphasia. Materials and Methods : The article has summarized information from different databases like Google Scholar and reviewed the factors influencing the recovery of aphasia after acute ischemic stroke. Results: The factors that really affect recovery are the initial severity of aphasia, which is inextricably linked to the size and location of the lesion. Conclusion: Stroke is the leading cause of long-term disability in Western countries and the functional outcome depends on the severity of the stroke. The initial severity of aphasia affects the recovery of language functions.
