Brief Summary
In people with Mild Cognitive Impairment (MCI) and Alzheimer's Disease (AD), reduced capacity for locomotor adaptation is a fundamental but poorly understood mechanism that can be a sensitive biomarker of cognitive-motor impairments. It is also an important therapeutic target for exercise-based interventions to improve walking function. The overall goal of this study is to understand the effects of MCI and AD on locomotor adaptation and walking function.
Eligibility Criteria
Inclusion Criteria: * AD and MCI will be defined through formal diagnosis provided by a board-certified Neurologist. Amnestic MCI will be defined using the AD Neuroimaging Initiative (ADNI) criteria. All MCI participants in ADNI are required to have an amnestic subtype defined as: * Subjective memory concern or a memory problem noted by their partner * Abnormal memory function documented by a specified education adjusted cutoff score on the delayed paragraph recall of the Anna Thompson story of the Logical Memory subtest from the Wechsler Memory Scale-Revised * Mini-Mental State Exam (MMSE) score between 20 and 26 (inclusive). Exceptions may be made for subjects with less than 8 years of education at the discretion of the PI. (iv) Single or multi-domain amnestic MCI (both subtypes are at high risk for progression to AD) * Clinical Dementia Rating (CDR) = 0.5 (Memory Box score must be at least 0.5) * General functional performance sufficiently preserved * Evidence of impaired executive
