Researchers at University College London (UCL) found that anxiety symptoms such as depression, sleep disturbances, fatigue, cognitive impairment, hypotension, tremors, stiffness, balance impairment and constipation were risk factors for the development of Parkinson's.

"Anxiety is known to be a feature of the early stages of Parkinson's disease, but before our study, the potential risk of Parkinson's in people over the age of 50 with new-onset anxiety was unknown," Dr Juan Bazo Álvarez, UCL Epidemiology and Health.

Dr. Juan said, "By understanding that anxiety and the mentioned characteristics are associated with a higher risk of developing Parkinson's disease over the age of 50, we hope that we may be able to detect the condition earlier and help patients "Can help you get the treatment you need." , noting that the disease is "projected to affect 14.2 million people by 2040".

For the research, published in the British Journal of General Practice, the team evaluated 109,435 patients who developed anxiety after the age of 50 and compared them with 878,256 matched controls who did not have anxiety.

The results showed that people with anxiety had twice the increased risk of developing Parkinson's compared to the control group.
