- Change in motor symptoms of Parkinson disease [ Time Frame: 12 months ]Change from baseline in the Movement Disorders Society-Unified Parkinson Disease Rating Scale motor score (Part III). The minimum score on the MDS-UPDRS Part III is 0 and the maximum is 132 with higher scores representing worse motor symptoms.

- Change in motor symptoms of Parkinson disease [ Time Frame: 18 months ]Change from baseline in the Movement Disorders Society-Unified Parkinson Disease Rating Scale motor score (Part III). The minimum score on the MDS-UPDRS Part III is 0 and the maximum is 132 with higher scores representing worse motor symptoms.

- Change in cognitive function [ Time Frame: 12 months ]Change from baseline in the Montreal Cognitive Assessment (MoCA). MoCA scores range between 0 and 30, with higher scores representing a better outcome.
- Change in cognitive function [ Time Frame: 18 months ]Change from baseline in the Montreal Cognitive Assessment (MoCA). MoCA scores range between 0 and 30, with higher scores representing a better outcome.
- Change in fitness [ Time Frame: 12 months ]Change from baseline in maximal oxygen consumption measured with peak oxygen volume
- Change in fitness [ Time Frame: 18 months ]Change from baseline in maximal oxygen consumption measured with peak oxygen volume
- Change in quality of life [ Time Frame: 12 months ]Change from baseline in quality of life measured with the Parkinson Disease Questionnaire-39. The PDQ-39 is a 39-item self-report questionnaire, which assesses Parkinson's disease-specific health related quality over the last month covering 8 dimensions scored on a 5 point ordinal system (0=never, 4=always). Dimension score = sum of scores of each item in the dimension divided by the maximum possible score of all the items in the dimension, multiplied by 100. Each dimension total score range from 0 (never have difficulty) to 100 (always have difficulty). Lower scores reflect better QoL. Overall score can be summarized in the Parkinson's Disease Summary Index (PDSI) or PDQ-39 Summary Index (PDQ-39 SI).PDSI or PDQ-39 SI = sum of dimension total scores divided by 8.

Ages Eligible for Study: | 40 Years to 80 Years (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- A diagnosis of idiopathic Parkinson Disease based on the modified * United Kingdom (UK) PD brain bank criteria and which are consistent with recent criteria proposed for clinically established early established Parkinson's disease that no longer exclude individuals with a family history of Parkinson's disease.
- Hoehn and Yahr stages less than 3
- Disease duration: less than 3 years since disease diagnosis
- Age 40-80 years
- Positive DaTscan™ SPECT by quantitative readout for idiopathic Parkinson disease.
Exclusion Criteria:
- Currently being treated with PD medications such as levodopa or dopamine receptor agonists, monoamine oxidase-B (MAO-B) inhibitors, amantadine, or anticholinergics.
- Expected to require treatment with medication for PD in the first 6 months of the study.
- Use of any PD medication 60 days prior to the baseline visit including but not limited to levodopa, direct dopamine agonists, amantadine, Rasagiline (Azilect), Selegiline (Eldepryl), Artane (trihexyphenidyl).
- Duration of previous use of medications for PD exceeds 60 days.
- Use of neuroleptics/dopamine receptor blockers for more than 30 days in the year prior to baseline visit, or any use within 30 days of baseline visit
- Presence of known cardiovascular, metabolic, or renal disease or individuals with major signs or symptoms suggestive of cardiovascular, metabolic, or renal disease without medical clearance to participate in the exercise program.
- Uncontrolled hypertension (resting blood pressure >150/90 mmHg)
- Individuals with orthostatic hypotension and standing systolic BP below 100 will be excluded. Orthostatic hypotension (OH) is a reduction of systolic blood pressure of at least 20 mm Hg or diastolic blood pressure of at least 10 mm Hg within 3 minutes of standing.
- Hypo- or hyperthyroidism (TSH <0.5 or >5.0 mU/L), abnormal liver function (AST or ALT more than 2 times the upper limit of normal), abnormal renal function (creatinine clearance calculated by the Cockcroft-Gault equation <50mL/min, or estimated glomerular filtration rate using the MDRD4 equation or the CKD-EPI equation <45mL/min/1.73m2 ).
- Complete Blood Count (CBC) out of range and physician's judgment that abnormal value is clinically significant.
- Recent use of psychotropic medications (e.g., anxiolytics, hypnotics, benzodiazepines, antidepressants) where dosage has not been stable for 28 days prior to screening.
- Serious illness (requiring systemic treatment and/or hospitalization) within the last 4 weeks.
- Any other clinically significant medical condition, psychiatric condition, drug or alcohol abuse, assessment or laboratory abnormality that would, in the judgment of the investigator, interfere with the subject's ability to participate in the study.
- Montreal Cognitive Assessment (MoCA) score of <24.
- Beck Depression Inventory II (BDI) score > 28, indicating severe depression that precludes ability to exercise. Any subject with such a score will be referred to a PCP or physician for further evaluation and management of depression. Individuals with a BDI-II score of 17-28 will be excluded if any of the following conditions are met: (1) individual is suicidal, (2) is in need of depression treatment modification currently or (3) depressive symptoms likely to interfere with adherence to study protocol. Any subject with such a score will be referred to a PCP or physician for further evaluation and management of depression.
- Individuals who have been exercising at greater than moderate intensity for 120 minutes or more per week consistently over the last 6 months will be excluded. Greater than moderate intensity is defined as a range greater than 60-65% HRmax. These individuals are excluded since their exercise activities are greater than the activities they would experience if they were assigned to the 60-65% treatment group. As such, they would be expected to lose fitness.
- Use of the following within 90 days prior to the dopamine transporter (DAT) neuroimaging screening evaluation: bupropion, modafinil, armodafinil, metoclopramide, alpha-methyldopa, methylphenidate, reserpine, any amphetamine or amphetamine derivative. These can compromise DaTscan™ SPECT.
- Known allergy to iodinated products.
- Known hypersensitivity to DaTscan™ SPECT (either to the active substance of 123I-ioflupane or any of the excipients.
- (For women only) Actively breast-feeding an infant, and/or pregnant, or plan to become pregnant in the next 12 months.
- Other disorders, injuries, diseases, or conditions that might interfere with ability to perform endurance exercises (e.g. history of stroke, respiratory problems, traumatic brain injury, orthopedic injury, or neuromuscular disease).
