Brief Summary:
Parkinson's disease is the second most common neurodegenerative disease affecting about 1-3% of population above 60 years. Recently, non-motor symptoms are getting more attention in PD management. The pattern of PD onset and clinical course differ from one population to another. Many studies have been conducted to determine the clinical profile of PD in populations worldwide. However, no similar studies have been conducted in Egypt. Therefore, the investigators will conduct a nation-wide, collaborative, cross sectional study to determine the pattern of Parkinson's disease onset, clinical course, and non-motor symptoms among Egyptian population.

Primary Outcome Measures :
  1. Age at disease onset [ Time Frame: At enrolment ]
    Patients age when the initial symptom appeared.

  2. Time to diagnosis [ Time Frame: At enrolment ]
    Duration, in years, from appearance of initial symptom to receiving Parkinson's disease diagnosis.

  3. Initial motor symptom [ Time Frame: At enrolment ]
    Number of patients with each initial motor symptom (tremor, rigidity, or bradykinesia).

  4. Side of initial motor symptoms [ Time Frame: At enrolment ]
    Number of patients with either right or left side initial motor symptoms.

  5. Clinical subtype of the disease [ Time Frame: At enrolment ]
    Number patients with each disease subtype (tremor dominant Parkinson's disease, hypokinetic-rigid dominant Parkinson's disease, or postural instability and gait disturbance dominant Parkinson's disease).

  6. Duration of levodopa treatment from disease onset [ Time Frame: At enrolment ]
    Number of years on levodopa treatment since receiving parkinson's disease diagnosis

  7. Levodopa equivalent dose [ Time Frame: At enrolment ]
    Current dose of levodopa per day

  8. Non-motor symptoms [ Time Frame: At enrolment ]
    Non-motor symptoms measured by the non-motor symptoms questionnaire (NMS)

  9. Quality of life [ Time Frame: At enrolment ]
    Mobility, activities of daily living, emotional well-being, stigma, social support, cognition, communication, and bodily discomfort assessed by the parkinson's disease quality of life questionnaire (PDQ-39).

Secondary Outcome Measures :
  1. Stage of the disease [optional] [ Time Frame: At enrolment ]
    The stage of the disease (stage 1, stage 2, stage 3, or stage 4) according to Hoehn and Yahr classification.

  2. Motor Functions [optional] [ Time Frame: At enrolment ]
    Motor functions assessed by the third part of the unified parkinson's disease rating scale (UPDRS III).
