Parkinson's disease can make swimming dangerous.
Researchers from the University of Zurich in Switzerland published a report which tells us about nine reported cases where patients with the disease have lost the ability to swim after treatment, namely after the procedure deep brain stimulation (DBS). DBS may help patients to control a range of neurological symptoms such as muscle spasms and stiffness. This suggests that despite good motor skills, deep brain stimulation can lead to the fact that people can drown. The report is published in the journal .
What is Parkinson's disease?
Parkinson's Disease is called a chronic neurological disease peculiar to older people. The disease affects the neural cells of the brain and is manifested movement disorders, tremor of the extremities and limitation of motion. With further development of the disease deteriorating mental abilities and develop mental illness. According to the world Health Organization (who), the number of people suffering from various neurological diseases, including Parkinson's disease, approximately 50 million people worldwide.
How to treat Parkinson's disease?
According to the researchers, prior to treatment, all subjects had problems with the swimming even after diagnosis. It seems that invasive procedure, which involves installing electrodes around the brain and heart to intercept erroneous electrical signals — this is what caused the loss of the ability to stay afloat. Despite the amazing picture, the researchers are not sure why DBS causes such a side effect. The report noted that after treatment, patients observed improvement of motor function, but in water the ability to coordinate disappears.
In pools inhabited by a variety of bacteria
The Interest of scientists to side effect of this procedure is likely to have been caused by the news that one of the patients jumped in the lake and almost drowned. In the future, the researchers learned that three of the nine patients were able to swim only after disconnecting the devices. Note that this is not the first time scientists noticed this strange connection. In 2015, researchers from Australia four such case studies, which lasted two decades. Three patients drowned after a sudden loss of ability to swim after DBS. Moreover, underwent the procedure were also noted violations of other specific physical abilities, such as Golf or skiing. Scientists have achieved great success in combating previously incurable diseases.
Today, this side effect leaves scientists with more questions than answers. Further research is needed to understand what is happening in the body of patients. Despite the fact that in the new document are just a few cases, the main reason why the doctors decided to write the report was to raise public awareness. Although the main reason may remains unknown, the decision to go swimming after the procedure, DBS may be worth people suffering from Parkinson's disease, life.
