Consider the following medical report that includes the patient's historical health records. Use it to predict the disease that the patient is high likely exposed to. 

 Medical Report: history of present illness: the patient is a year old gentleman with a history of parkinson's disease, hypertension, previous right basal ganglion infarction in , who presented on , after having an episode of confusion and right facial droop in the setting of an elevated systolic blood pressure of 220. the patient was treated by his physician with zestril with improvement of these symptoms. the morning of admission the patient developed a change in his mental status with slurred speech and decreased responsiveness. he was again noted to have a right facial droop and his systolic blood pressure was in the 200s. he was brought to the emergency department for further evaluation. past medical history: 1. parkinson's disease. 2. hypertension. 3. right hemicolectomy. 4. small bowel resection. 5. peptic ulcer disease. 6. benign prostatic hypertrophy. 7. macular degeneration. 8. prior right basal ganglion infarction in . 9. paranoid delusions. medications on admission: 1. paxil 5 mg q.d. 2. calcium carbonate 650 mg p.o. b.i.d. 3. sinemet 25/100 two tablets p.o. q.6:00 a.m., 10:00 a.m., 2:00 p.m., 6:00 p.m. 4. zestril 10 mg p.o. q.d. 5. lopressor 12.5 mg p.o. b.i.d. 6. multivitamin. allergies: no known drug allergies. social history: the patient is a nursing home resident. his code status is dnr/dni. physical examination: on general physical examination, the patient was afebrile with a heart rate of 62, blood pressure 220/102, respiratory rate 18, oxygen saturation 98% in room air. his neck was supple without bruits. his cardiovascular examination revealed a regular rate and rhythm, no murmurs, rubs or gallops. his lungs were clear to auscultation bilaterally and his abdomen was benign. neurologic examination demonstrated alternating level of alertness and he was disoriented to place when asked to choose from a list. he did not know the town but was aware of the state. he was not oriented to time including day of week and year. he followed simple commands inconsistently. his attention was poor and a slight right gaze preference was noted on extraocular examination. the pupils are equal, round, and reactive to light and accommodation bilaterally. he had a mild right facial droop. spontaneous movements in his extremities favored the use of his left arm. he was able to lift his right arm against gravity. the patient withdrew both legs to noxious stimuli but had minimal voluntary movement. tone was slightly decreased in the right arm and leg. there was no evidence of cogwheel rigidity. reflexes were also diminished in the right arm and leg. laboratory data: electrocardiogram demonstrated slight st segment elevations in the anterior leads. magnetic resonance scan demonstrated t2 hyperintensity in the left greater than right corona radiata consistent with a watershed ischemic infarction. hospital course: the patient was admitted to the neurosurgical intensive care unit for closer monitoring of his ischemic cerebral infarction. the patient's blood pressure was closely monitored and he was maintained on aggrenox for antiplatelet therapy. a carotid duplex was obtained and showed minimal right internal carotid artery plaque. on his second hospital day, the patient was noted to have a decreased level of responsiveness. he was described as not opening his eyes to sternal rub. a repeat cat scan of the brain was obtained which demonstrated evidence of his prior infarction of the left corona radiata. there was no acute bleed or mass effect. the patient was transferred to the neurologic service on his fourth hospital day and at that time would open his eyes to voice but had no spontaneous verbal output and would not follow commands. repeat magnetic resonance scan of the brain was obtained that demonstrated a near complete left anterior cerebral artery occlusion. the patient's change in mental status was attributed to abulia. these findings were discussed with the patient's family including the sister, the concern being that he would no longer be capable of taking p.o. nutrition without the need for a percutaneous endoscopic gastrostomy tube. his family felt that the patient would not want to be dependent on tube feeds in this manner and would prefer hospice care. the patient's code status was changed from dnr/dni to comfort measures only. the patient is to be transferred back to his nursing home facility of center for hospice care. , m.d. dictated by: medquist36 procedure: enteral infusion of concentrated nutritional substances diagnoses: pneumonia, organism unspecified unspecified essential hypertension paralysis agitans cerebral artery occlusion, unspecified with cerebral infarction 

Answer: The patient is high likely exposed to
