Behind every person living with Parkinson’s, there are years of symptoms that were ignored, misinterpreted, or simply invisible. Because the disease does not begin with tremor, it begins much earlier.
On April 11, World Parkinson’s Day, we focus on one of the greatest challenges in neurology today: moving toward earlier, more precise, and more human diagnosis in neurodegenerative diseases.
A diagnosis that still comes too late
Parkinson’s disease is the second most common neurodegenerative disorder, yet delayed diagnosis remains one of its biggest challenges.
The most visible symptoms (tremor, rigidity, and slowness of movement) usually appear when the disease has already been progressing silently for years. Earlier signs often go unnoticed:
- REM sleep disturbances
- Loss or changes in smell
- Emotional symptoms such as anxiety or apathy
Identifying these early signals is one of the key challenges in current research.
From symptoms to biomarkers: a paradigm shift
Parkinson’s research is undergoing a major transformation: moving from a model based solely on motor symptoms to a precision-based approach integrating biological, genetic, and clinical data.
Biomarkers are central to this shift. Their development could:
- Enable detection before visible symptoms appear
- Reduce diagnostic uncertainty
Genetics and heterogeneity: Parkinson’s is not a single disease
Recent advances show that Parkinson’s is not one uniform condition but a group of diseases with different causes and trajectories.
Genetic research is key to enabling personalized treatments.
Collaborative research as a driver of progress
Progress depends on collaboration across institutions.
CIBERNED exemplifies this model.
Beyond clinical care: impact on daily life
Parkinson’s affects autonomy, relationships, and daily living.
A comprehensive approach is essential: medical care, emotional support, and long-term follow-up.
The real challenge: anticipation
Detecting earlier and acting with precision is not just a scientific goal, it is a necessity.
At Ace Alzheimer Center Barcelona, we work every day toward this goal.
