Currently, diagnosis of Parkinson’s disease relies on a neurologist’s professional opinion. Researchers behind a new study believe that an EEG may be a more effective alternative.
Parkinson’s disease affects more than 10 million people worldwide, according to the Parkinson’s Foundation, but no scan has been proved to definitively diagnose it.
Instead, a neurologist will assess a person by asking them to carry out certain tasks. These may include writing or drawing, walking, and speaking.
They will also examine the face and limbs to check for signs of tremors and facial expression difficulties.
