  8. Ability to return to clinic for additional visits over a 12 month period.
  9. ≥ 10 years of education or enough work history to exclude mental retardation.
  10. Adequate visual and auditory acuity to allow neuropsychological testing.
  11. Screening laboratory tests and ECG without significant abnormalities that might interfere with the study.

  12. History of familial early onset (<55 years old) dementia
  13. Pacemaker or other medical device of metal that precludes performing MRI.
  14. Subjects who have been engaged in moderate intensity aerobic exercise training for > 30 minutes, 3 times per week over the past 2 years.
  15. History of a clinical diagnosis of B12 deficiency or hypothyroidism. (stable treatment for at least 3 months is allowed).
  16. Chronic inflammatory diseases including, lupus, rheumatoid arthritis and polymyalgia rheumatica.

Prohibited Medications:

  • narcotics
  • anti-Parkinsonian medications
  • anti-convulsants for treatment of seizure disorder
  • drugs that can influence psychometric test results.

    • Subjects on a statins or non-steroidal anti-inflammatory drug (NSAID) are eligible but must be on a stable dose for at least 2 months.

Outcomes

Primary Outcome Measures

Cognitive function
A comprehensive battery of neuropsychological tests focused on memory and executive function will be used to assess effects of exercise on cognitive function.

Secondary Outcome Measures

Cerebrovascular function
Transcranial Doppler and perfusion magnetic resonance imaging (MRI) will be used to measure cerebrovascular function/brain perfusion before and after exercise training.
Brain tissue volume and white matter integrity
Magnetic resonance imaging (MRI) will be used to measure changes in brain volume and white matter integrity before and after exercise training.

5. Study Description

Brief Summary
This study is being done to find out whether regulation of brain blood flow is altered in patents with mild cognitive impairment (those who have memory problems but otherwise healthy) when compared with healthy elderly individuals. In addition, this study will determine whether exercise training improves brain blood flow, brain structure, and brain function in patients with mild cognitive impairment (MCI). This is a research study because at present the investigators know little about brain blood flow regulation in patients with mild cognitive impairment. The investigators also know little about whether exercise training improves brain blood flow, brain structure, and brain function in patients with mild cognitive impairment.
Detailed Description
We plan to study 70 patients with amnestic MCI and 30 healthy older adults with similar age, sex, and educational level in this research at the University of Texas Southwestern(UTSW) Medical Center Dallas and Texas Health Presbyterian Hospital Dallas - Institute for Exercise an Environmental Medicine (IEEM). To help decide if you qualify to be in this study, the researchers may ask you questions about your health, including medications you take and any surgical procedures you have had. You may also have to fill out certain forms or have the following exams, tests or procedures. The screening process usually takes 2-3 hours. You will be required to come for 7-9 visits including the initial screening for eligibility to participate in this study. The experiments will measure your brain perfusion, vascular function and exercise capacity. For the healthy controls, the expected length of this study will be about 2-3 months including all the test visits. Your participation in this study will end following completion of your testing. For those with Mild Cognitive Impairment, the expected length of this study will be about 18 months including all the test visits and exercise training. Your participation in this study will end following completion of your repeat testing after one-year exercise training or control intervention. On occasion, training may be delayed due to injury, illness or personal matters. If this is the case, your enrollment in the study may last longer than one year as we attempt to complete the training and testing.
