This study was published in the scientific journal JAMA Neurology. In it, a group of researchers from Queen Mary University of London sought to unravel the health conditions that may be precursors or warning signs of Parkinson’s disease.
For this, the researchers analyzed the stories of health over one million people who lived in east London between 1990 and 2018. The data included 1055 people who developed Parkinson’s disease during the period analysed.
The results showed that the typical signs of diseases, such as tremors and memory loss, could already be observed in patients five to ten years before the diagnosis was made. But, in addition to these symptoms, two others have proven to be reliable warning signs of the disease: epilepsy and hearing loss.
According to the results of the study, hearing loss signaled a 66% increase in the risk of developing Parkinson’s disease in patients. The reason for this may be the onset of changes in brain function caused by the disease, the researchers speculated.
“Although the role of early hearing loss requires further investigation, it is possible that this factor represents another deficit in sensory processing that occurs as part of the pathogenesis of Parkinson’s disease, similar to visual impairment,” said neurologist, doctoral student, in a statement and study leader, Cristina Simonet.
However, the association with epilepsy was even more significant. Patients with epilepsy have a 2.5-fold increase in the risk of developing Parkinson’s disease at some point in their lives.
Additionally, the research pointed out that there are studies that have already established links between epilepsy drugs and Parkinson’s disease. This points to possible causation that requires further research. THE to look for points out that the prevalence of epilepsy in Parkinson’s patients was found to be higher than estimated.
The study sent a wake-up call to healthcare professionals, as the new research does not explore the issue further: “It is important for primary care professionals to be aware of these links and understand how early symptoms of Parkinson’s disease may appear so that patients can get timely treatment. diagnosis and doctors can act early to help manage the disease.
While it is important to pay attention to these new symptoms associated with the disease, they are not the only indications. The Parkinson’s Foundation points to other early symptoms to watch out for, such as tremors, small handwriting, loss of smell, difficulty walking, constipation, low voice, dizziness, fainting and falling. If you have noticed any of these symptoms, talk to your doctor.
