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: patient recorded as having no known allergies to drugs attending: chief complaint: dementia and rapid worsening of symptoms following mvc major surgical or invasive procedure: right craniotomy for evacuation of subacute sdh history of present illness: 63yo m w/ known frontal dementia was found wandering around schoolyard, was brought to ed and found to have a subacute sdh. pt experienced an mvc in mid- and subsequently experienced rapid worsening of his confusion, and he was subsequently unable to continue working as an engineer. past medical history: hearing loss, htn social history: lives w/ wife, stopped working as engineer family history: non-contributory physical exam: o: t: 97.8 bp: 105/69 hr: 58 r: 12 o2sats:98% ra gen: comfortable, nad. heent: perrl, eom intact neck: supple. lungs: cta bilaterally. cardiac: rrr. s1/s2. abd: soft, nt, bs+ extrem: warm and well-perfused. neuro: mental status: awake and alert, not cooperative with exam, significant hearing loss contributes to difficulty with exam orientation: oriented to person, not to place or date language: speech fluent, no word-finding problems, little comprehension- pt is very off topic when answering questions cranial nerves: i: not tested ii: pupils equally round and reactive to light, 3 to 2mm bilaterally iii, iv, vi: extraocular movements intact bilaterally v, vii: unable to evaluate facial strength and sensation due to lack of pt cooperation. viii: hearing intact to very loud yelling, known hearing deficit ix, x: palatal elevation symmetrical. : sternocleidomastoid and trapezius unable to asess. xii: tongue midline without fasciculations. motor: normal bulk and tone bilaterally. no abnormal movements, tremors. no pronator drift. moving 4 extremities, unable to evaluate strength due difficulty with communication, but strength globally intact sensation: intact to light touch bilaterally. reflexes: 2+ biceps reflex bilaterally, unable to obtain other reflexes toes downgoing bilaterally pertinent results: ct head findings: there is a large partly isodense, hypodense and partly hyperdense subdural collection along the right cerebral hemisphere. the widest component measures 3.1 cm and causes sulcal effacement and leftward subfalcine herniation by 9 mm. this is minimally larger than the prior measurement of 8 mm leftward subfalcine herniation. there is a left parieto-occipital component, measuring 1.5 cm, unchanged. there are no new foci of intra- or extra-axial hemorrhage. impression: unchanged bilateral acute to subacute on chronic subdural hematomas, larger on the right side causing a leftward 9 mm subfalcine herniation. ct head findings: the patient is status post right parietal craniotomy, with a drainage catheter noted traversing the right cerebral convexity, status post subdural hematoma evacuation. there has been significant interval decrease in size of the mixed attenuation right holohemispheric subdural hematoma, which now contains both hypodense and a small amount of hyperdense material which is new. there is residual sulcal effacement and mass effect identified. also noted in a hypodense subdural fluid collection adjacent to the tentorium which is new, measuring 6mm in diameter, likely secondary to redistribution. a small amout of pneumocephaly is also noted throughout the subdural space on the right. no significant midline shift is identified. a left holohemispheric subdural hematoma is again identified containing hypo, iso and a small interval increase in hyperdense blood, causing a small interval increase in the size of the left occipital component, now measuring 2.1 cm in depth, previously measuring 1.5 cm in depth. again noted is sulcal effacement within the left occipital region. there is no intraparenchymal hemorrhage or loss of -white matter differentiation. the basilar cisterns are patent. cavernous carotid artery calcifications are noted bilaterally. post-surgical changes are noted within the calvarium. the visualized paranasal sinuses are clear. impression: 1. significant interval reduction in the size of the right holohemispheric subdural collection status post subdural drain placement and craniotomy. interval increase in a small amount of hyperdense material reflecting a new small amount of acute blood. 2. interval increase in the volume of the left occipital subdural component with a small amount of hyperdense material consistent with acute on subacute/chronic subdural hematoma. 3. small hypodense subdural collection along the right tentorium, likely secondary to redistribution. ct head findings: since the prior study, there has been apparent removal of a right- sided subdural drainage catheter. there is a small amount of hyperdense material, presumably acute blood within the peripheral portion of this subdural fluid collection, at the site of the former drainage catheter, but which was present before the catheter was removed, as well. at least in the vertex portion of the much larger hypodense component, there does appear to be some expansion in width of the fluid collection. tthe left parietal collection, having mixed density subdural hemorrhage, also appears slightly greater in width near the vertex portion, compared with the prior study. the interhemispheric subdural fluid collection, right- sided and located posteriorly on the prior study, appears to have resolved at this time. at most, there is a millimeter or two leftward shift of the septum pellucidum. there remains very slight compression of the right lateral ventricle. there has been no other change in ventricular size. there is a small amount of gas within the scalp adjacent to the metallic staples on the right side, and somewhat more extensively within the right frontal and subdural space. conclusion: slight expansion of bilateral cerebral convexity subdural fluid collections on both sides, compared with the prior study, with additional findings described above. brief hospital course: mr presented to the er at for evaluation and was found to have a large right subacute sdh. he was taken emergently to the or where he had right craniotomy and the sdh was evacuated. he tolerated the procedure well but post-operatively he required haldol for agitation. on he was oob to chair and his subdural drain was removed. he was then transferred to the sdu. on ct head showed increase size but no acute bleeding in left sdh as a result of his decrease subdural blood collection on the right. this was followed clinically and radiographically without any further change. on he was transferred from the icu to the surgical floor. neurology was consulted while on the surgical floor. as he has been followed by dr over the last two years he has been followed by dr. for worsening language difficulties as well as dr. of cognitive neurology, most recently in for likely primary progressive aphasia. postoperatively, patient has been reported to be agitated upon arrival to the sicu from the or, where he was given a total of 30mg iv haldol and 2mg iv ativan that day as well as required 4-point restraints. thereafter, he continued to be confused, restless, impulsive, agitated, possible hallucinations (pt was worried about a "fire") and needed regular redirection. he was only oriented to self and occasional to "hospital." however, pt was noted to be less agitated with his family at the bedside. he was transferred to the floor on and has continued to be agitated and difficult to re-direct, requiring haldol, seroquel, restraints, and 1:1 sitter. as per his sitter, he has been walking into other patients' rooms, pulling out his iv, standing in front of the room with clothes off, and reaching for things that are not there. he did not sleep at all overnight and only slept for 15 minutes this am. he was started on keppra 750mg (has been on phenytoin for seizure prophylaxis) and seroquel 25mg today as well as haldol 0.5mg prn. a metabolic work up was started and unrevealing. seroquel seemed to help control the patients aggitation at night. the patient was changed back to dilantin to decrease aggitation. the patient was found to have a urinary retention, he was cathed of 1000cc of urine. his aggitation improved after catheterization. he was started on flomax, he will discharged with a catheter and follow up in urology. he was cleared by pt he will have a home safety eval, he was tolerating a regular diet and his aggitation improved on discharge. medications on admission: donepezil,
