Inclusion Criteria:

Individuals with IPS diagnosed for less than 4 years and who present in Hoehn & Yahr Stages I/II and fulfill the United Kingdom Parkinson's Disease Society Brain Bank Criteria
The result of a DAT-SPECT and MRI examination of the patient's brain has to be consistent with the diagnosis of PD
Written Informed Consent Form signed and dated by the patient
Age between 45 and 70
Female patients of childbearing potential are eligible if they use a medically accepted contraceptive method
A potential participant treated with conventional PD therapies must be on stable doses for at least 3 months prior to Visit 0 and during the entire trial period and must be a stable responder
Accepted PD medications include the following: levodopa (alone or in combination with benserazide, carbidopa), Catechol-O-methyltransferase inhibitors (entacapone, tolcapone), amantadine, non-ergot dopamine agonists (pramipexol, ropinirol, rotigotine), monoamine oxidase-B inhibitors (rasagiline, selegiline) and anticholinergic medication
A potential participant has to be on stable doses of all medications he/she is taking because of consisting illnesses according to medical history (except PD therapies, these will be recorded separately) for at least 30 days prior to Visit 0, if considered relevant by the PI
Upon PI's opinion, no visual or auditory impairments that would reduce the patients' ability to complete study questionnaires or be unable to receive instructions for these

Exclusion Criteria:

Pregnant women
Sexually active women of childbearing potential who are not using a medically accepted birth control method throughout the study

History of questionable compliance to visit schedule; patients not expected to complete the clinical trial
