Cerebrovascular diseases are the leading cause of morbidity and mortality worldwide. Unfortunately, Bulgaria leads most countries in its incidence of stroke. Furthermore, a substantial number of Bulgarian patients post-stroke present with persisting communication disorders, especially aphasia. The main purpose of the present study is to conduct an evidence-based theoretical review of leading international guidelines for treatment and rehabilitation of adult stroke patients. In particular, this theoretical overview compares the current Bulgarian guidelines with those developed by the United States of America, Europe, Australia, Canada, the United Kingdom, and New Zealand. The Bulgarian guidelines for the prevention, diagnosis, and treatment of cerebrovascular diseases strongly recommends pharmacological treatment, which is commensurate with international standards. Nationally, a range of different language tests are currently used in post-stroke aphasia.
