Brief Summary
This study is designed to assess the safety and toxicity/adverse events associated with the use of low dose fractionated whole brain irradiation in those patients who have been diagnosed with probable Alzheimer's disease according to the National Institute of Neurological and Communicative Disorders and Stroke and the Alzheimer's Disease and Related Disorders Association (NINCDS-ADRDA) criteria. As a secondary goal it will establish whether or not the intervention with low dose whole brain irradiation might change the recognized progression of Alzheimer's Disease. The investigators will also collect information from the florbetaben F 18 Injection (AMYVID®) positron emission tomography (PET) Scans to determine if there is any correlation between neurocognitive/quality of life scores and changes in amyloid plaque size, number and location.

Outcome Measures
Primary Outcomes (4)
Common Terminology Toxicity Criteria for Adverse Events (CTCAE) Version 5.0 - 6 Weeks
To assess a change from baseline in adverse conditions, utilizing Common Terminology Toxicity Criteria (Version 5.0) assessing skin, eyes, ears, and central nervous system at 6 weeks post-treatment. Each condition/event will be given a score based on severity . The CTCAE displays Grades 1 through 5 with unique clinical descriptions of severity for each adverse event (AE): (Grade 1=1 point, Grade 2=2 points, Grade 3=3 points, Grade 4=4 points. Grade 5=5 points) and event scores added to produce a total patient score. Minimum score is zero, which represents no adverse events. Maximum score is 72. A higher score means a worse outcome. The total patient score at baseline subtracted from the total score at 6 weeks is reported. A positive number indicates an increase in adverse conditions, while a negative number indicates decreased adverse conditions.
Baseline to 6 weeks post-treatment
Common Terminology Toxicity Criteria (CTCAE) Version 5.0 - 3 Months
To assess a change from baseline in adverse conditions, utilizing Common Terminology Toxicity Criteria (Version 5.0) assessing skin, eyes, ears, and central nervous system at 3 months post-treatment. The CTCAE displays Grades 1 through 5 with unique clinical descriptions of severity for each AE: (Grade 1=1 point, Grade 2=2 points, Grade 3=3 points, Grade 4=4 points. Grade 5=5 points) and event scores added to produce a total patient score. Minimum score is zero, which represents no adverse events. Maximum score is 72. A higher score means a worse outcome. The total patient score at baseline subtracted from the total score at 3 months is reported. A positive number indicates an increase in adverse conditions, while a negative number indicates decreased adverse conditions.

The total patient score at baseline subtracted from the total score at 6 months is reported. A positive number indicates an increase in adverse conditions, while a negative number indicates decreased adverse conditions.
6 months post-treatment
Common Terminology Toxicity Criteria (Version 5.0) - 12 Months
To assess a change from baseline in adverse conditions, utilizing Common Terminology Toxicity Criteria (Version 5.0) assessing skin, eyes, ears, and central nervous system at 12 months post-treatment. The CTCAE displays Grades 1 through 5 with unique clinical descriptions of severity for each AE: (Grade 1=1 point, Grade 2=2 points, Grade 3=3 points, Grade 4=4 points. Grade 5=5 points) and event scores added to produce a total patient score. Minimum score is zero, which represents no adverse events. Maximum score is 72. A higher score means a worse outcome. The total patient score at baseline subtracted from the total score at 12 months is reported. A positive number indicates an increase in adverse conditions, while a negative number indicates decreased adverse conditions.

Study Arms (2)
Cohort One
EXPERIMENTALAn initial 15 patients will be enrolled in the first treatment scheme (5 daily fractions of 2 Gy) and will be followed for 12 months after completion of treatment to assess safety and any toxicity/adverse events associated with treatment. 15 patients will be enrolled and each will be followed for 12 months to assess safety and toxicity/adverse events.
Cohort Two
EXPERIMENTALThe second treatment arm will not be used until the last patient in the first dose arm has completed all follow up. At that point patients #16-30 will be enrolled in the second dose arm (10 daily fractions of 2 Gy). 15 patients will be enrolled and each will be followed for 12 months to assess safety and toxicity/adverse events.
