Precision Medicine Approach for Early Dementia & Mild Cognitive Impairment

The goal of this clinical trial is to compare a precision medicine approach to the standard-of-care for people with mild cognitive impairment or early-stage dementia. Precision medicine approach starts with the completion of many tests and then the study doctor uses the test results to carefully prepare a treatment plan that is best for the individual person to help treat many of the underlying causes of mild cognitive impairment or early-stage dementia. The main question the study aims to answer is: • Does the precision medicine approach improve memory (cognitive function) better than the current standard-of-care treatment in people with mild cognitive impairment or early-stage dementia during a 9-month treatment period? This is a randomized clinical trial which means that a group of people that meet the study requirements will be assigned at random or by chance (like toss of a coin) to receive either the precision medicine treatment or the current gold standard (standard-of-care). People assigned to the precision medicine group will receive precision medicine for 9-months while those assigned to the standard-of-care group will follow that approach for 9-months, followed by an opportunity to receive up to six months of precision medicine, if desired. Participants will be asked to: * Have their blood drawn for extensive lab testing and collect urine and stool samples as well * Carefully follow instructions received from their study doctor and study team * Make lifestyle changes as prescribed by the study doctor and study team based on your precision medicine program * Take supplements and medications prescribed by the study doctor. * Once officially in the study (after meeting study entry or screening requirements), participate in ten (10) monthly visits with the study doctor, and other members of the study team as scheduled. * Complete cognitive tests at scheduled visits during the study * Have a study partner with you during visits and to help support you on t
