A 75-yeаr-оld right-hаnded mаn was tоld in the past by his internist that he had an irregular heartbeat. The patient decides that he dоes not wish to learn anything further about this condition, so he does not return to this physician, and it remains untreated. One morning, he awakens to find that his face droops on the right side, and he cannot move his right arm or right leg. When he tries to call an ambulance for help, he has great difficulty communicating with the operator because his speech is slurred, non-fluent, and missing some pronouns. The call is traced by the police; an ambulance arrives at his house and takes him to an emergency room. A neurologist is called to see the patient in the emergency room. He detects an irregular heartbeat when he listens to the patient's heart. It is challenging to understand his speech because it is halting, and he repeatedly repeats the exact phrases. He has difficulty repeating specific sentences given to him by the neurologist, but he can follow simple commands such as "Touch your right ear with your left hand." His mouth droops on the right when he attempts to smile, but his forehead remains symmetric when he wrinkles it. He cannot move his right arm but wiggle his right leg slightly. Which of the following language problems does this patient have?
