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: allergies: epogen attending: chief complaint: subdural hematoma and mental status changes. major surgical or invasive procedure: none history of present illness: pt is an 80 yo male w/ pmhx sig for atrial fibrillation on coumadin, pm/icd, htn, cri on hd admitted to ed after traumatic fall. pt apparently had a mechanical fall walking to dialysis this morning. he fell down and hit his head but had no loc. upon initial presentation to the ed, the patient was a&o x3 and moving all of his extremities without any asymmetry. ct head showed a small, acute left frontal sah and a subacute-on-chronic left frontoparietal subdural hematoma. ~ 5 pm the patient was noted to have decompensate, with slurred speech, r facial droop, and decreased movement of r arm. he was intubated for airway protection. repeat ct scan head performed and showed ct head showed small subdural hematoma, l parietal. had laceration, occipital. past medical history: cabgx5 pacemaker/icdf implanted ' esrd, on dialysis , , sat anemia social history: no etoh or tobacco, no illicit or ivdu family history: noncontributory physical exam: vitals: t 97; bp 150/65; p 67; rr 10; o2 sat 100% on vent general: intubated w/ c-collar in place heent: posterior laceration pulmonary: cta b/l cardiac: regular rate and rhythm, with no m/r/g abdomen: soft, nontender, non distended, normal bowel sounds extremities: no c/c/e. neurological exam: mental status: intubated, does not respond to voice cranial nerves: perrl, 4-->2mm with light. + vor, + corneal reflex, r facial droop. motor/: normal bulk. normal tone. rle externally rotated. minimal withdrawal to pinch l >r. reflexes: reflexes 3+ on r with upgoing toe, 2+ on l with toe downgoing. pertinent results: eeg study date of impression: this is a mildly abnormal portable eeg in the waking and drowsy states due to the bursts of generalized delta frequency slowing. this is a non-specific abnormality suggestive of deep subcortical midline dysfunction. there were no epileptiform discharges noted. of note, however, there were frequent premature ventricular contractions. l-spine (ap & lat) 12:41 pm 1. degenerative changes of the lumbar spine without acute compression deformities. 2. dilated loop of featureless bowel within the abdomen, likely colon. this is a nonspecific bowel gas pattern. if there is abdominal pain, dedicated abdominal views could be obtained. ct head w/o contrast 5:45 am non-contrast ct head: there has been no significant change in acute on chronic subdural hemorrhage along the left cerebral convexity measuring approximately 8 mm in greatest distance off the inner table of the skull with mild associated mass effect. hyperdense collection of blood within the subarachnoid spaces adjacent to the subdural hemorrhage may be slightly less conspicuous. the approximately 4 mm subfalcial herniation is unchanged. posterior subgaleal hematoma is again noted with skin staple in place. the and mastoid air cells remain well aerated and an ng tube is partially imaged. impression: no significant interval change in the size and appearance of the left subdural hematoma. unchanged rightward subfalcial herniation. ct head w/o contrast 1:30 pm findings: along the posterior aspect of the parietal bone, in the superficial tissues, there is an area of soft tissue swelling with hyperdense/hemorrhagic components, several foci of air and two staples consistent with an acute subgaleal hematoma. along the left parietal convexity, there is a low- attenuation crescentic collection with several hyperdense foci, representing either acute hemorrhage or fibrovascular membranes, consistent with a subdural hematoma. there is a hyperdense fluid- fluid level within the dependent portion of this subdural collection, representing "hematocrit effect." within the left frontal lobe, just suprajacent to the subdural hematoma, there is a linear hyperdensity within a sulcus, consistent with a small focus of subarachnoid hemorrhage. there is minimal rightward shift of approximately 2 mm. there is no discernable mass effect on the left lateral ventricle. there is no hydrocephalus or major vascular territorial infarction. the density values of the brain parenchyma are maintained. mild periventricular white matter change is consistent with chronic small vessel disease. incidental note is made of calcifications of the vertebral arteries, bilaterally. the visualized portion of the paranasal sinuses and mastoid air cells are unremarkable. impression: 1. small, acute left frontal focus of subarachnoid hemorrhage. likely early subacute-on-chronic left frontoparietal subdural hematoma. minimal associated mass effect. 2. posterior parietal subgaleal hematoma, with no skull fracture. ct c-spine w/o contrast 1:31 pm there is no malalignment or acute fracture of the cervical spine. there is extensive multilevel spondylosis. there is mild neural foraminal narrowing on the left at the c3-4 and c4-5 levels. there is no significant spinal canal stenosis, with ct is unable to provide intrathecal detail comparable to mri. incidental note is made of extensive atherosclerotic calcifications of the carotid and vertebral arteries. impression: no acute fracture or alignment abnormality. mild degenerative disease of the cervical spine. labs: 08:00a 134 97 agap=17

for atrial fibrillation, pm/icdf, esrd on dialysis who presents after traumatic fall w/small l sah and sdh subsequently developed r facial weakness, vomiting, and altered ms. the patient was monitored in the icu setting and subsequently extubated without event. his mental status markedly improved in the early days following admission. at time of discharge he was oriented to place, time, person without significant neurologic deficit. interval head ct obtained revealed stable subdural hematoma (full results detailed above). he was evaluated by physical therapy who recommended rehab placement given numerous recent falls. hemodialysis was continued during this admission in addition to darbepoietin(to which he does not have an allergy) for the pt's chronic anemia. cardiology consultation was obtained for ? aicd malfunction in the setting of the patient's possible syncopal episode prior to admission. they found the lead placement to be aberrant and suggested further testing for possible lead exchange. this was discussed at length with the patient, his family, and cardiology consultants, and it was decided not to pursue further intervention with regard to his aicd given the associated risks of the procedure. cardiology further recommended starting metoprolol low dose, stopping digoxin as he is on hd, and starting a statin after checking lfts and cpk. the patient should follow up with dr. in four weeks with an interval ct scan of the head prior to the appointment. the patient will need to schedule a follow up appointment with dr.
