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: s/p fall major surgical or invasive procedure: none history of present illness: pt is a 80 yo female w/ pmhx sig for parkinson's, htn, hypercholesterolemia medlflighted from after fall with evidence of sah and frontal contusions on head ct. the patient was at home and fell backwards down a 8 stairs and landed on the back of her head. her gcs was 8 at the seen and she was noted to have hematoma a the back of her head. she was brought to where she had a head ct that demonstrated sah, b/l frontal contusions with iph, r temporal pneumocephalus, and non-displaced occipital bone fracture. she was intubated, paralyzed, and medflighted to . past medical history: parkinson's disease w/ signs of mild dementia, htn, hypercholesterolemia, moh's procedure. social history: lives with husband on . she has a visiting nurse 5 days/week. she walks with a walker. family history: non-contributory physical exam: upon admission: physical exam: vitals: t 97.9; bp 131/66; p 58; rr 16; o2 sat 100% general: intubated, sedated heent: dried blood around mouth neck: c-collar extremities: no c/c/e. neurological exam: intubated, does not repsond to voice, perrl, 4-->2mm with light, + vor, + corneal reflex, no spontaneous movements, does not withdraw to pain, trace reflexes in ues and absent in les. pertinent results: ct head : impression: 1. extensive subarachnoid hemorrhage and parenchymal hemorrhagic contusion, increased from prior outside examination. 2. occipital bone fracture on the left, with concern for sinus injury and venous epidural hematoma along the left occipital bone. subdural blood layers along the tentorium. 3. nondisplaced clivus fracture with possible involvement of the right carotid canal. cta of the head is recommended for further evaluation. ct chest/abd/pelvis : impression: impression: 1. somewhat limited study given respiratory motion, especially in the chest. 2. no evidence of acute traumatic injury in the chest, abdomen, or pelvis. 3. right adnexal cystic lesion and small amount of pelvic free fluid. if clinically indicated (based on patient's prognosis), non-urgent pelvic ultrasound can be performed for further evaluation. 4. chronic degenerative changes of the lumbosacral spine, with likely chronic malalignment at multiple levels as described. mra brain : impression: no definite evidence of dissection. this is a limited examination related with motion artifacts, the distal branches of the circle of are not clearly identified, either related with artifact or possible vasospasm secondary to subarachnoid hemorrhage, please correlate clinically. based the axial source images, no dissection or major vascular occlusion is identified. ct head : impression: 1. extensive subarachnoid, intraparenchymal and subdural hematoma, not significantly changed. no shift of normally midline structures. 2. mild prominence of the temporal horns which may represent early hydrocephalus although is unchanged when compared to prior exam. 3. multiple skull fractures with possible involvement of the right internal carotid artery canal. 4. air-fluid levels in the sphenoid and right maxillary sinus are similar in appearance. ct head : mild decrease in the previously noted subarachnoid and intraparenchymal hemorrhage in the occipital lobes. no significant change in the areas of hemorrhage noted in the intraparenchymal, subdural and subarachnoid compartments, otherwise. no new hemorrhage. multiple skull fractures are inadequately assessed on the present study. please see the detailed report on the prior cts. brief hospital course: pt is a 80 yo female w/ pmhx sig for parkinson's, htn, hypercholesterolemia medlflighted from after fall with evidence of sah and frontal contusions on head ct. the patient was at home and fell backwards down a 8 stairs and landed on the back of her head. her gcs was 8 at the seen and she was noted to have hematoma a the back of her head. she was brought to where she had a head ct that demonstrated sah, b/l frontal contusions with iph, r temporal pneumocephalus, and non-displaced occipital bone fracture. she was intubated, paralyzed, and medflighted to . upon arrival to a repeat head ct was obtained. pt was loaded with dilantin. her levels were above 20 and this medication was held for this reason on and . her neurologic status did not improve and the family had a meeting with dr. . she was made cmo on . she was extubated on this date and was pronounced that evening. medications on admission: sinemet, mirapex, midodrine discharge medications: none discharge disposition: expired discharge diagnosis: subarachnoid hemorrhage subdural hematoma intraparenchymal hemorrhage hydrocephalus nondisplaced clivus fracture left occipital bone fracture discharge condition: expired discharge instructions: none followup instructions: none md procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours enteral infusion of concentrated nutritional substances diagnoses: obstructive hydrocephalus pure hypercholesterolemia unspecified essential hypertension open wound of scalp, without mention of complication paralysis agitans accidental fall on or from other stairs or steps closed fracture of base of skull with cerebral laceration and contusion, with prolonged [more than 24 hours] loss of consciousness, without return to pre-existing conscious level 

Answer: The patient is high likely exposed to
