Parkinson's disease (PD) is a neurodegenerative disorder that affects the central nervous system. It is characterized by the loss of dopaminergic neurons in the substantia nigra of the brain. Dopamine is a chemical that helps control movement. The loss of dopaminergic neurons causes symptoms such as tremors, stiffness, slowness of movement, and difficulty maintaining balance.
PD is a chronic disease that has no cure and affects 10 million people worldwide, but there are treatments that can help control symptoms. The most common treatments are levodopa therapy, dopamine agonist therapy, and deep brain stimulation surgery.
Recently, it has been discovered that smartwatches can be used to detect Parkinson's disease. Smartwatches can measure a number of physiological parameters, such as heart rate, respiratory rate, and body temperature. These parameters can be altered in people with PD, even before symptoms appear.
A 2019 study by researchers at the University of Oxford, UK, found that smartwatches can detect Parkinson's disease with 90% accuracy. The study was carried out with a group of 100 people, 50 of whom had PD and 50 did not, and the participants wore a smartwatch for a period of 12 months.
The researchers analyzed the data from the smartwatch looking for changes in physiological parameters. They found that people with PD had significant changes in heart rate, respiratory rate, and body temperature. These changes were detectable even before the PD symptoms appeared.
The results of this study suggest that smartwatches could be used to detect Parkinson's disease in its early stages. This would allow patients to start treatment sooner, which could improve their quality of life.
A similar study has been carried out by researchers at Cardiff University (in Wales, UK) measuring data from the accelerometer and other parameters of the smartwatch, and taking the data to a "maching learning" model.
However, it is important to note that smartwatches are not a definitive test for Parkinson's disease. If someone has any suspicion that they may have PD, it is important to see a doctor as soon as possible.
Below are some of the benefits of using a smartwatch to detect Parkinson's disease:
- Smartwatches are portable and easy for anyone to use.
- Smartwatches can continuously measure a series of physiological parameters, which can be altered in people with PD.
- Smartwatches could detect Parkinson's disease in its early stages, allowing patients to start treatment as soon as possible, and improve their health.
With this I do not mean that everyone should wear a smartwatch, but if a person suspects that they may have the disease, they should talk to a specialist to see if a smartwatch could help them.
It's better to prevent than to cure.
