About

The overall objective of this study is to determine how high intensity endurance exercise affects both cognition and the signs and symptoms of Parkinson's disease as well as if certain brain structures and functions also change with this exercise.

Full description

The overall purpose and objective of this project is to test the hypothesis that high intensity endurance exercise causes beneficial brain adaptation in patients with mild cognitive impairment in Parkinson's disease (PD-MCI). Aim 1 will determine the effect of high intensity endurance exercise on cognitive function and other clinical symptoms in PD-MCI. Aim 2 will determine the effect of high intensity endurance exercise on brain structure and function in PD-MCI. Aim 3 will determine the effect of high intensity endurance exercise on cortisol in PD-MCI. Aim 4 will determine the effect of high intensity endurance exercise on inflammation-related biomarkers found in blood in PD-MCI. Aim 5 will determine the effect of high intensity endurance exercise on peripheral levels of neurotrophic factors found in blood in PD-MCI.

Volunteers

No Healthy Volunteers

Inclusion criteria

Male or female, ages 40-85
A diagnosis of idiopathic PD
A diagnosis of PD-MCI
Due to the stringent head motion during fMRI, we will only include a patient with a head tremor of < 2.
Hoehn and Yahr stage < or equal to 3
Stable medication regimen for > or equal to 30 days before entering the study
Living with a carepartner

Exclusion criteria

PD subjects meeting MDS criteria for PD dementia or having a SCOPA-Cog score less than or equal to 16, or PD subjects having normal cognition defined as a SCOPA-Cog Score of is greater or equal to 25.
Atypical or secondary parkinsonism as determined by referring Neurologist
Other disorders that might interfere with ability to perform high intensity endurance exercise (e.g. history of stroke, respiratory problems, traumatic brain injury, known advanced osteoarthritis, or neuromuscular disease).
Individuals with known injury, disease, or condition that would affect the ability to perform endurance exercise.
Any other clinically significant medical condition, psychiatric condition, drug or alcohol abuse that would, in the judgment of the investigator, interfere with the subject's ability to participate in the study.
"Vigorous athletes" participating in any exercise program 2X/week or more will be excluded.
Individuals with any type of implanted electrical device (such as a cardiac pacemaker or a neurostimulator), or a certain type of metallic clip (i.e., an ° Persons who have had a long history of working in metal shops will be excluded unless they have had a previous orbital x-ray scan clearing them for participation in MRI studies.
Females who are pregnant or might be pregnant will be excluded from participation.
Individuals who are claustrophobic and unable to tolerate a brain MRI scan will be excluded.
Treatment with cholinesterase inhibitors or memantine (i.e., medications approved for treatment of dementia) or medications affecting cognition (i.e., anticholinergics)
Use of medications that might interfere with neuromuscular junction function such as D-penicillamine and aminoglycoside antibiotics.
Use of medications that might interfere with the BOLD contrast or heart response to exercise (e.g. β blockers).
Individuals at high risk for cardiovascular disease as defined in Table 2.2 by the new ACSM guidelines.(Medicine 2014)
Younger than 40 and older than 85. We exclude participants younger than 40 because these young onset patients may not be typical of the majority of patients who get the disease later in life. We exclude participants older than 85 because of the limited evidence they can successfully complete a high-intensity endurance exercise program. We also exclude patients whose disease was diagnosed before the age of 40.
Individuals with known endocrine abnormalities or steroid use that could affect cortisol levels (e.g., Cushing's syndrome, pituitary or adrenal gland disease or adrenalectomy, use of steroid-based medications.
Individuals with strong history of chronic inflammatory or autoimmune diseases or history of chronic use of NSAIDs, which could cause abnormal levels of inflammatory markers in the plasma.
We will exclude adults unable to consent, individuals who are not yet adults, pregnant women, prisoners and children from this study.
