Which of the following is a common symptom of Ischemic CVA involving speech?

Slurred speech is a common symptom of an ischemic cerebrovascular accident (CVA), commonly known as a stroke. This condition occurs when there is a reduction in blood flow to a part of the brain, often due to a clot obstructing a blood vessel. The part of the brain responsible for language and speech production can be affected, leading to difficulties in articulating words and forming coherent sentences.

Those experiencing slurred speech may struggle to pronounce words clearly, resulting in a mumbled or unclear speech pattern. This symptom often accompanies other neurological deficits, such as weakness on one side of the body or facial drooping, and can help healthcare providers quickly identify the possibility of a stroke, leading to prompt treatment.

The other symptoms listed, such as difficulty swallowing, increased clarity of speech, and inability to smile, represent different clinical presentations that could be associated with other disorders or conditions but are not as directly indicative of ischemic CVA as slurred speech.
