Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The current study will last for 12 weeks and will involve people with AD. Participants will be initially examined with an overnight brain wave study to assess for silent epileptic (seizure-like) activity. Presence of epileptic activity on the screening exam is not required to enter the trial. Participants will then be assigned to groups in a randomized manner. One group will receive levetiracetam for 4 weeks, then no drug for 4 weeks, and then placebo for 4 weeks. For another group, the order of treatments will be reversed. The cognitive abilities of participants will be retested every 4 weeks and compared to those at the beginning. The cognitive tests include a virtual-reality navigation test of memory and computerized tests of mental flexibility and problem solving. The participants will be monitored with a magnetoencephalogram (MEG) with simultaneous EEG (M/EEG) at each visit. M/EEG is a highly effective non-invasive method for identifying brain regions of epileptic activity. The investigators will need to recruit 36 randomized participants to test the study hypotheses. This study will take place at the University of California, San Francisco (UCSF) and the University of Minnesota.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Exclusion Criteria
Any conditions which could account for cognitive deficits in addition to AD, including but not limited to Vitamin B12 or folate deficiency, abnormal thyroid function, posttraumatic conditions, syphilis, multiple sclerosis or another neuroinflammatory disorder, Parkinson's disease, vascular or multi-infarct dementia, Huntington's disease, normal pressure hydrocephalus, central nervous system (CNS) tumor, progressive supranuclear palsy, subdural hematoma, etc.; Previous history of a seizure disorder, excepting cases where the first seizure or detection of epileptiform activity was within 5 years of screening and the patient is not prescribed an anticonvulsant; Significant systemic medical illnesses; Use of medications likely to affect CNS functions (e.g., benzodiazepines, narcotics); Severe renal dysfunction with creatine clearance \< 30 ml/min, which would affect serum LEV levels; Participation in another AD clinical trial within 3 months of Screening, or any AD clinical trial, such as a vaccine, that has potential long-term effects; Treatment with another study drug or investigational drug within 30 days of Screening; Pregnant or lactating; Any other medical condition which is determined by the investigators to potentially create an undue risk for an adverse effect; Biomarker evidence unsupportive of a diagnosis of AD.
