“World Parkinson’s Day” is celebrated today, on the day of the birth of Dr. James Parkinson, the first to recognize the disease as a medical condition. Which concerns a significant number of people: according to the Rare Diseases Observatory, in 2023 there were 300 thousand Parkinson’s patients in Italy. It is a multifaceted neurological disease that manifests itself with different symptoms. The causes unknown. It occurs more frequently around the age of 60 although there is no shortage of cases among those under 50: around 10% of sufferers are under 50. Tremor, slowness of movement, muscle rigidity and difficulty writing are the best-known symptoms. Other symptoms – reduced sense of smell, sleep disturbances, depression and constipation (tiredness) – may precede the onset of movement disorders by years. But it is difficult to relate them to Parkinson’s. There is no known cure although some pharmacological therapies are available which, especially in the early stages of the disease, allow good control of the symptoms. The anniversary offers an opportunity for discussion for patients, families and healthcare workers with the aim of increasing knowledge about the disease and its impact on individuals, their caregivers and their communities.
