Visual function changes in a Parkinson's Disease cohort - preliminary data.

Area of Science:

• Neurodegenerative disorders
• Neurology
• Public Health

Background:

• Parkinson's disease (PD) is the second most common neurodegenerative disorder.
• Global prevalence of PD has significantly increased, rising from 2.5 million in 1990 to 6.1 million in 2016.
• PD is increasingly viewed as a syndrome with complex features beyond motor symptoms.

Purpose of the Study:

• To highlight the growing global prevalence of Parkinson's disease.
• To emphasize the importance of non-motor symptoms in early PD diagnosis.
• To advocate for increased public awareness, early recognition, and neuroprotective interventions for PD.

Main Methods:

• The abstract does not specify methods but discusses prevalence data and diagnostic criteria.
• Analysis of global prevalence trends from 1990 to 2016.
• Inclusion of non-motor features in current diagnostic criteria.

Main Results:

• Worldwide prevalence of Parkinson's disease (PD) has dramatically increased.
• Non-motor symptoms can manifest up to twenty years before the onset of classic motor symptoms.
• Current diagnostic criteria for PD now incorporate non-motor features.

Conclusions:

• Increased public awareness and early detection of PD are vital.
• Timely neuroprotective interventions can significantly enhance the quality of life for individuals with PD.
• Urgent measures are needed to counteract the rising global prevalence of Parkinson's disease.
