Trial Title: Effect of Mental Imagery Training on Brain Plasticity and Motor Function in Individuals With Parkinson's Disease

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: DOUBLE
- Phase: None
- Number of Arms: 3.0

Eligibility Criteria:
Inclusion Criteria:~* Subjects with a diagnosis of idiopathic PD defined according to the UK Brain Bank diagnostic criteria and on a stable dopaminergic medication regimen will be included.~Exclusion Criteria:~* Age \< 40 years~* Non-English speaking~* Pregnancy~* Breastfeeding~* Excessive alcohol consumption (\> 7 drinks per week for women, \> 14 drinks per week for men) or substance use~* History of a neurological disorder such as a brain tumor, stroke, central nervous system infection, multiple sclerosis, movement disorder (other than PD), or seizures~* History of schizophrenia, bipolar disorder, attention deficit disorder, or obsessive compulsive disorder~* History of head injury with loss of consciousness~* Metallic surgical implants or traumatically implanted metallic foreign bodies~* Inability to lie flat for about an hour~* Discomfort being in small, enclosed spaces~* Dementia (Montreal Cognitive Assessment score \< 21)~* Depression (Beck Depression Inventory-II score \> 19)~* Hoehn \& Yahr stage \> 3 (i.e., able to stand and walk, but not fully independent)~* Focal neurological findings on exam that suggest cerebral pathology other than that associated with parkinsonism~* Motor symptoms that could potentially introduce too much motion artifact in the imaging data (e.g., MDS-UPDRS resting tremor score \> 1 in limbs, head/chin tremor, or dyskinesia by history or exam).

- Gender: ALL
- Minimum Age: 40 Years
- Maximum Age: None
- Healthy Volunteers: f

Study Arms:
- Patients with PD neurofeedback training (Type: EXPERIMENTAL): Patients will receive neurofeedback training.
- Patients with PD control (Type: ACTIVE_COMPARATOR): Patients will not receive neurofeedback training.
- Patients with PD (Type: NO_INTERVENTION): Patients perform mental imagery (motor and visual aspects combined) in the MRI scanner without neurofeedback training.

Based on this trial design, predict the completion outcome and termination type (if applicable).
