A stroke is one of the most catastrophic experiences an individual can undergo. Strokes often cause temporary or permanent paralysis on one side of the body. Balance, memory, speech, cognition, and vision may also be affected. In addition, muscle spasms and pain are common complications of a stroke. Because of these issues, stroke survivors may have difficulty managing basic tasks such as bathing and dressing. Consequently, it may be challenging for them to continue to manage their roles as spouses, parents, or employees.

One of the most serious complications of stroke is difficulty communicating, with many stroke patients experiencing a decrease in speaking ability. Research shows about 25 to 40 percent of stroke patients suffer aphasia, a disorder that impairs one’s ability to process language. While it does not affect intelligence, aphasia can make it challenging for the patient to speak and understand others, while also impeding their abilities to read and write.
