Loss Of Ability To Smell
Hyposmia, or a loss of smell, is often one of the first Parkinson’s disease symptoms. It can arise years, perhaps decades, before a formal diagnosis is made. This symptom is often overlooked or attributed to age or other factors. According to one study, Parkinson’s disease-related brain alterations could start in the regions responsible for smell. While not limited to Parkinson’s disease, persistent scent loss may necessitate further medical attention. The only way to find out its cause is to have it looked at by a professional.
