14 Signs That May Be Parkinson’s Disease

11. Loss of Smell

Anosmia (loss or reduction of smell) is widespread in Parkinson’s disease, with up to 95% of patients suffering it to some degree. It’s one of the first signs, and patients frequently report losing their sense of smell before they have any mobility problems. Although the cause of Parkinson’s disease is unknown, new research discovered that the area of the brain that processes smell, known as the ‘olfactory bulb,’ was smaller in a sample of Parkinson’s patients.

People are affected in different ways when they lose their sense of smell. Because we rely on our sense of smell to taste food, a lack of smell might result in weight loss or growth.
