Brief Summary:
The purpose of this study is to determine whether caloric vestibular stimulation improves symptoms of Parkinson's Disease.

Condition or disease Intervention/treatment Phase
Parkinson's Disease and Parkinsonism Device: Caloric Vestibular Stimulation Device: Sham Caloric Vestibular Stimulation Not Applicable

Detailed Description:
Parkinson's Disease (PD) is a nationwide public health problem, inflicting a complex constellation of physical and neuropsychiatric symptoms which are shown to progress with time. This research will investigate the potential of caloric vestibular stimulation (CVS), a non-invasive form of brain stimulation, as a treatment for individuals who suffer from Parkinson's Disease. Investigators will investigate whether core cognitive and physiological deficits are responsive to stimulation by comparing participants' performance on behavioral and physiological measures after baseline and either active or placebo stimulation phases with the aim of drawing initial insights into the application of CVS within this population. The study design is based on a single-case study that recently demonstrated durable, clinically meaningful gains in the motor and cognitive symptoms of PD.

Arm Intervention/treatment
Active Comparator: Active
Participants will be receiving an active Caloric Vestibular Stimulation treatment for a duration of 12 weeks, 7 days a week, twice daily for 20 minutes.
Device: Caloric Vestibular Stimulation
Stimulation of the vestibular nerves

Sham Comparator: Placebo

Participants will be receiving a Sham Caloric Vestibular Stimulation treatment for a duration of 12 weeks in the same manner as the active arm: 7 days a week, twice daily for 20 minutes.

Individuals allocated to this arm will be later crossed over, in unblinded fashion. to the active arm if the treatment shows evidence of efficacy and safety.

Device: Sham Caloric Vestibular Stimulation
Sham stimulation of the vestibular nerves
Other Name: Placebo

Primary Outcome Measures :
  1. Unified Parkinson's Disease Rating Scale (UPDRS). questionnaire [ Time Frame: 16 weeks ]
    We expect changes mainly in the motor subscale.

  2. 2 Minute Walk behavioural measurement [ Time Frame: 16 weeks ]
    Distance walked by the patient in 2 minutes is measured.

  3. 10 Meter Walk behavioural measurement [ Time Frame: 16 weeks ]
    An average time of a normal-speed and fast-speed of gait on a distance of 10 meters taken three times is measured.

  4. Timed Up and Go behavioural measurement [ Time Frame: 16 weeks ]
    time taken to get up from a chair, walk 3 meters, go back and sit down is measured.

  5. Montreal Cognitive Assessment (MoCA) Questionnaire [ Time Frame: 16 weeks ]
    cognitive ability test

  6. EQ-5D-3L Questionnaire [ Time Frame: 16 weeks ]
    Activity of daily living scale

  7. Schwab and England Scale Questionnaire [ Time Frame: 16 weeks ]
    Health Questionnaire

  8. PD-39 Questionnaire [ Time Frame: 16 weeks ]
    Health-related Parkinson's Disease questionnaire

  9. Hospital Anxiety and Depression Scale Questionnaire [ Time Frame: 16 weeks ]
    depression and anxiety questionnaire

  10. Epworth Sleepiness Scale Questionnaire [ Time Frame: 16 weeks ]
  11. Fatigue Severity Scale Questionnaire [ Time Frame: 16 weeks ]

Secondary Outcome Measures :
  1. EEG/Event - Related Potentials abnormalities - Physiological measurement [ Time Frame: 16 weeks ]
    Assessment of any changes to P300 during ERPs and beta wave in a resting state.

  2. SPECT DaTSCAN - Physiological measurement [ Time Frame: 16 weeks ]
    Assessment of any changes in the concentration of dopamine within the central nervous system
