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: this is a 75 year old white male transferred from with a history of a recent fall late on the evening of the , at which time he landed on the back of his head with a report of a loss of consciousness for an unknown period of time. the patient reported that he awoke and noted he was still at home and others took him to the emergency room. at the , a ct scan was positive for a small subacute right sided frontal parietal subdural hematoma with layered blood posteriorly, which was felt to be new since the prior ct scan done after a fall on . the patient was therefore transferred to the for further neurosurgical assessment and a plan. past medical history: 1. recent history of falls. 2. history of unstable angina in the past. 3. history of chronic atrial fibrillation. 4. history of a transient ischemic attack in . 5. history of peptic ulcer disease. 6. gastroesophageal reflux disease. 7. history of chronic obstructive pulmonary disease. 8. history of seizure disorder status post an motor vehicle accident in . past surgical history: 1. history of three-vessel coronary artery disease status post stent in . 2. bilateral carotid endarterectomies in . 3. abdominal aortic aneurysm repair in . 4. transurethral resection of the prostate in . 5. status post subdural hematoma secondary to motor vehicle accident in . this reportedly was never evacuated and after which he developed a seizure disorder. allergies: he has no known drug allergies. medications at the time of admission: 1. aspirin 1 p.o. q. day. 2. dilantin 100 mg p.o. three times a day. 3. imdur 30 mg p.o. q. day. 4. atenolol 25 mg p.o. twice a day. 5. zocor 20 mg p.o. q. day. 6. coumadin, which was discontinued after the fall,8 hours prior to admission. 7. nitroglycerin p.r.n. 8. sotalol 80 mg p.o. twice a day. social history: he reports he quit tobacco smoking 20 years prior to admission. he denies the use of alcohol. physical examination: on physical examination, he was an elderly appearing white male seen while supine in bed, awake, alert, confused, but knows his name and knew the day's date but did not know the place or follow any simple commands very well. he had a positive left upper extremity drift and the pupils were equal, round and reactive to light and accommodation. his extraocular movements are intact. peripheral field examination was inconsistent. he moved all extremities. strength was five over five in all groups. there was a mild left pronator drift. the sensory examination was intact but limited secondary to poor patient compliance. on deep tendon reflexes the patient was tense in all extremities and reflexes were unable to be obtained at the time of examination due to increased tone. plantar responses were downgoing weakly bilaterally. the neck was supple without nodes or adenopathy. the lungs were clear. the heart showed an irregularly irregular rate and rhythm consistent with atrial fibrillation. abdominal examination was soft and nontender, nondistended, and bowel sounds were present in all four quadrants. extremities were without cyanosis, clubbing or edema. he was transferred to the hospital with venodyne on, so the venodyne were present at the time of examination. laboratory: review of the ct scan dated the revealed a subacute subdural hematoma of the right frontal parietal area measuring approximately 2.1 cm thick and approximately 6.0 cm long, along the right frontal parietal area with a slight midline shift and preservation of the -white junction and moderate widening and prominent sulci on the left, which was consistent with long-standing brain atrophy. coagulation studies at at 07:55 a.m. on the , were reported as a pt of 21, ptt 31.6 and an inr of 2.86. hospital course: due to the clinical findings, the patient was admitted to the hospital neurosurgical intensive care unit and arrangements were made for inr to be corrected with fresh frozen plasma urgently, with a goal to get the inr below 1.3. a repeat ct scan was scheduled for the morning and the patient was admitted to the hospital neurosurgical intensive care unit. upon review with dr. , on the following day the patient was felt to have a subdural hematoma with indication for evacuation of the clot and due to the findings, the patient was taken to the operating room where the patient underwent a bur-hole drainage of the subdural hematoma with placement of a subdural drain. the patient tolerated the procedure well and was returned to the neurosurgical intensive care unit in stable condition. the patient's neurologic status improved moderately. he still showed evidence of occasional confusion. physical examination was otherwise unchanged and the subdural drains were removed on the second postoperative day after adequate drainage and repeat ct scans confirmed a reasonably good drainage. the patient was subsequently transferred to the floor, however, due to an episode of respiratory distress while out on the medical-surgical floor, the patient was urgently re-intubated and readmitted to the neurosurgical intensive care unit. he was suctioned aggressively and found to have multiple mucous plugs and tolerated this well. a chest x-ray was obtained which showed a small pneumothorax. a chest tube was placed by the cardiothoracic service and he was followed in the neurosurgical intensive care unit for several more days. the chest tube was subsequently removed. the patient was returned again to the medical-surgical floor and did well for several days. he was subsequently transferred to hospital on , with follow-up to see dr. in the clinic in several weeks' time. condition at discharge: stable and improved. disposition: discharge to the for aggressive physical therapy and occupational rehabilitation services as an inpatient. , md dictated by: medquist36 procedure: continuous invasive mechanical ventilation for 96 consecutive hours or more incision
