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 an 89 year-old male with a past medical history significant for hypertension, diabetes, gastroesophageal reflux disease, amyloid angiopathy and questionable problem and dementia. the patient presented to the emergency department the day prior to admission with a chief complaint of change in mental status and status post multiple falls. per the patient's family there was no loss of consciousness and no head trauma. the ct scan in the emergency department showed subacute subdural hematoma, but no evidence of trauma. the patient was to be admitted to neurosurgery for observation and then drainage, but while in the mri waiting for the scan the patient had an episode of unresponsiveness with bradycardia and relative hypotension. the patient was urgently intubated and repeated ct was read as showing no acute change. the patient was then admitted to the micu service. past medical history: 1. amyloid angiopathy. 2. hypertension. 3. diabetes. 4. gastroesophageal reflux disease. 5. cervical spondylitis. 6. dementia. social history: no tobacco and no alcohol use. allergies: no known drug allergies. physical examination on admission: vital signs the patient was afebrile with a heart rate of 51, blood pressure 126/66. the patient was intubated and sedated elderly gentleman. the patient's eye was closed, reactive. pupils are equal, round and reactive to light, though small pupil. heart rate was regular, bradycardia in the low 50s. no murmurs, rubs or gallops. lungs are clear bilaterally to auscultation. no wheezes or rhonchi. abdomen soft, nontender, nondistended. positive bowel sounds. extremities was warm and well perfuse. no edema. laboratories on admission: the patient's white blood cell count was 8.4, hematocrit 31.2, platelets 156. electrolytes were within normal limits. inr was 1.1 and normal tsh level. cardiac enzymes were negative. ct scan showed subdural hematoma. mra showed left ventricular artery had severe stenosis and there is multiple infarct in white matter area unchanged from previous study. hospital course: the patient was admitted to the micu on the day of admission and his condition stabilized. the patient though was intubated, but soon was stable enough to be extubated and there is no recurrence of bradycardia and no recurrence of hypotensive episodes. therefore the patient was transferred out to the regular floor on from the micu. while on the floor the patient's mental status was waxing and . the patient has questionable underlying alzheimer's disease/dementia. we took off all of the psychiatric medications and the patient has been experiencing steady mental status decline per his neuropsychiatric doctor dr. and the patient has been quite confused for at least several months prior to being admitted when dr. saw the patient. the patient also had word finding difficulties and especially confused at night. the patient required one to one sitter while in the floor to prevent him from going to bathroom or getting out of bed by himself given that he has a high fall risk due to his underlying dementia as well as his poor muscle coordination. as for his diabetes he was being covered on regular insulin sliding scale. his sugar has been quite stable throughout the hospital stay. there is no active issues. as for his hypotensive episode while in the emergency department it has not been recurred and his blood pressure returned to his baseline and he eventually required his antihypertensive medications metoprolol b.i.d. after his blood pressure returned to the baseline of high normal level. condition on discharge: stable. discharge status: to home with services including physical therapy and home safety evaluation. discharge diagnoses: 1. confusion. 2. subdural hematoma. discharge medications: 1. atenolol 25 mg po q.d. 2. atorvastatin 10 mg po q.d. 3. tylenol 325 mg take one to two tablets q 4 to 6 hours as needed. 4. pantoprazole 40 mg po q.d. 5. lisinopril 5 mg po q.d. follow up plans: the patient was instructed to follow up with dr. in one to two weeks for a blood pressure check and also the patient was instructed to have a repeated cat scan of the head to evaluate the progression of hematoma. , m.d. dictated by: medquist36 procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours insertion of endotracheal tube cardiopulmonary resuscitation, not otherwise specified diagnoses: unspecified essential hypertension abnormality of gait other specified cardiac dysrhythmias cardiac arrest diabetes with other specified manifestations, type ii or unspecified type, not stated as uncontrolled alzheimer's disease subdural hemorrhage other specified disorders of circulatory system 

Answer: The patient is high likely exposed to
