Visit 1: Consent/Assent will be obtained before any study related procedures are performed. Once consent is obtained subjects will be assessed to determine eligibility based on study inclusion/exclusion criteria. A history and physical with possible neurological examination will be conducted. Cognitive impairment will be assessed by having the subject complete the Folstein Mini-Mental State Exam (MMSE).
Qualifying subjects who wish to participate in the study will be scheduled to return for a study orientation visit. Subjects are required to have a study partner. Subjects will be given a copy of the study partner informed consent form (ICF) to take home with them. A potential study partner(s) must attend the orientation visit with the subject.
Visit 2: Study Orientation: ICF will be obtained from subject study partner(s). Subjects and their study partner(s) will be given information about what is required for the study. They will be given the patient logs that are to be kept at home between sessions and discussed with study staff at the following session. Subjects and study partners will be trained to become proficient in checking their blood sugar with one of the common blood glucose meters as well as how to use a supply of glucose which can cover any potential hypoglycemic reaction. Subjects and/or their study partners will be oriented to the location where the controlled pulsatile IV insulin infusion therapy will be performed. They will be instructed on where to park and where to go when they arrive.
Visit 3: Pre-Therapy Amyloid PET scan
Visits 4 - 28: Insulin Therapy Visits: Subjects will complete 25 insulin therapy sessions which will occur on a weekly basis, over 6 months. Prior to insulin treatment the following assessments will be completed: MMSE, CDT, QOLS, and CGI. Also prior to insulin therapy, as well as between insulin therapy treatments, basal O2 and C O2 measurements will be obtained.
Pre labs will be collected at visit 4, mid labs at visit 16, and post labs at visit 28.
Visit 29: Post-therapy Amyloid PET Scan
Visit 30: The final study visit will be conducted in the Psychopharmacology Research Clinic within one month of the subject completing the last insulin treatment.

- cerebral glucose metabolism [ Time Frame: 25 weeks ]Cerebral glucose metabolism will be measured using pre and post FDG PET Scans.
- cognition [ Time Frame: 30 weeks ]Changes in cognition will be measured before therapy, on a weekly basis during therapy, and after therapy using the Folstein Mini-Mental State Exam (MMSE) and the Clock Drawing Test (CDT).
- general clinical improvement [ Time Frame: 30 weeks ]Changes in general clinical improvement will be measured before therapy, on a weekly basis during therapy, and after therapy using the Clinical Global Impression (CGI) and the Quality of Life Scale (QOLS).
- basal metabolism [ Time Frame: 30 weeks ]Changes in basal metabolism will be measured before therapy, during weekly treatment sessions, and after therapy using measured O2 and CO2 levels.
