Every stroke presents differently. If you have seen one stroke. You've seen one stroke. The part of the brain is deprived of oxygen determines what physically impaired.
Three concepts we have learned are receptive (Wernicke's) aphasia, expressive (Broca's) aphasia, and dysarthria.
Receptive aphasia affects the Wernicke's area of the temporal lobe which permits the understanding of spoken language. A person that has had a stroke in this area would not be able to follow commands or answer questions.

This man in the YouTube, was a former dentist. He does produce audible words but they do not answer the questions the therapist asked.
Expressive aphasia affects the Broca's area of the frontal lobe which sends motor messages to muscles that are used to speak.

This man in the YouTube, believes that he is answering the questions being asked. but audible words are not coming out. Instead he repeats "Tono tono tono" with hand motions and variation in voice tone and pitch just like normal speech was coming out.
Dysarthria is a disruption of the coordination of speech. Speech comes comes out but not clear or steady. The speech that comes answers the questions asked and makes sense but not particularly clear. The cerebellum coordinates movement and speech. Dysarthria hinders the coordination of speech.
