The investigators are also studying how inflammation is related to the symptoms that first occur in patients with Alzheimer\'s disease (AD). For this reason, the investigators are asking people with different versions of Alzheimer\'s disease and/or other related dementias to participate. This includes patients with:\n\n* Mild Cognitive Impairment\n* Posterior cortical atrophy - a version of Alzheimer\'s disease with vision difficulties\n* Logopenic variant primary progressive aphasia - a version of Alzheimer\'s disease with language difficulties\n* Amnestic Alzheimer\'s disease - a "typical" version of Alzheimer\'s disease with memory difficulties\n* The investigators are also enrolling older adults with normal visual, language, and memory function.', 'detailedDescription': "This study is being done to learn about inflammation in Alzheimer's disease so that the investigators can find out new ways to treat patients with this disease. Because Alzheimer's disease usually causes slow changes to the brain over time, in this study the investigators are going to perform different tests and then repeat some of them two years later.\n\nInflammation can be measured using a type of brain scan called a positron emission tomography (PET) scan. A PET scan uses very small amounts of a radioactive drug that is injected into a vein to create a special picture of the brain. The inflammation PET scan uses a drug called ER176. ER176 is an experimental drug but has been used in several human studies before. Once in the body, ER176 sticks to areas with lots of inflammation, and the PET scan allows us to see these areas.\n\nInflammation can also be measured by looking at certain proteins in the spinal fluid. In order to measure these proteins in the spinal fluid, the investigators need to perform a lumbar puncture (spinal tap). Certain genes that inherited from parents influence the amount of inflammation in the body. The investigators can study how genes affect inflammation in Alzheimer's disease by looking doing genetic tests on blood that collected from the vein.\n\nThe investigators can study how genes affect inflammation in Alzheimer's disease by doing genetic tests on blood. The investigators will also be testing blood for severe acute respiratory syndrome (SARS)- CoV-2 (the virus that causes COVID-19) antibodies. The investigators want to see if exposure to the virus that causes COVID-19 changes the amount of inflammation in the brain or not.\n\nAlong with inflammation, Alzheimer's disease is also associated with the build up of the proteins amyloid and tau in the brain. The investigators can measure these proteins using PET scans. The amyloid PET scan uses a drug called florbetaben that has been approved by the FDA to help diagnose Alzheimer's disease. The tau PET scan uses a drug called MK-6240. Like ER176, MK-6240 is experimental but has been used in several human studies before.\n\nA brain MRI creates a high resolution picture of the brain. The brain MRI helps the investigators get more information from the PET scans, and can also tell the investigators the size and appearance of different brain structures. When someone has Alzheimer's disease, some of these brain structures get smaller or have altered appearance on MRI."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '50 Years', 'healthyVolunteers': True, 'eligibilityCriteria': "Inclusion criteria:\n\n1.

Controls must have Clinical Dementia Rating scale score of 0 at enrollment.\n4. Subjects unable to provide informed consent must have a surrogate decision maker.\n5. Written and oral fluency in English or Spanish.\n6. Able to participate in all scheduled evaluations and to complete all required tests and procedures.\n7. In the opinion of the PI, the subject must be considered likely to comply with the study protocol and to have a high probability of completing the study.\n\nExclusion criteria:\n\n1. Past or present history of a brain disorder other than Alzheimer's disease (including presence of cortical infarct on MRI even in absence of clinical stroke).\n2. Serious medical conditions, which make study procedures of the current study unsafe. Such serious medical conditions include uncontrolled epilepsy and multiple serious injuries.\n3. Contraindication to MRI scanning.\n4. Conditions precluding entry into the scanners (e.g. morbid obesity, claustrophobia, etc.).\n5. Exposure to research related radiation in the past year that, when combined with this study, would place subjects above the allowable limits.\n6.
