Parkinson’s disease is a neurodegenerative pathology which is characterized by the destruction of certain neurons in the brain and by the accumulation of toxic clusters for nerve cells. In France, experts estimate that Parkinson’s disease affects approximately 160,000 people, mostly over the age of 80; in addition, each year there would be 25,000 new diagnoses.
Several scientific studies have already identified certain factors favoring the development of Parkinson’s disease: thus, people with schizophrenia, who have been exposed to pesticides or who have Attention Deficit Disorder with or without Hyperactivity (ADHD) would be at risk increased to develop this pathology.
“Pre-diagnostic manifestations” that could predict the onset of the disease
In a new study published this Monday, March 7, 2022 in the specialized journal JAMA Neurologyresearchers from Queen Mary University of London (in Great Britain) list two new “pre-diagnostic manifestations“that could predict future development of Parkinson’s disease: seizures and hearing loss.
The British researchers studied medical records of 1,055 people with Parkinson’s disease who were followed between 1990 and 2018. They found that, in these patients, epilepsy and hearing impairment could be considered “warning signs” of a future diagnosis of Parkinson’s disease.
These early signs could therefore allow increased monitoring and early detection of Parkinson’s disease. Indeed: on average, patients with Parkinson’s experience diagnostic wandering for 1 to 3 years.
