Dizziness and vertigo are commonly reported symptoms in people with Parkinson’s disease (PD). Dizziness is a term used to describe a range of sensations, such as being on the verge of fainting, feeling woozy, weak or unsteady. Dizziness that creates the false sense that you or your surroundings are spinning or moving is called vertigo. All types of dizziness can lead to balance problems.
In general, both symptoms are less notable in people in the early stages of Parkinson’s. It is more common for older people with Parkinson’s to experience dizziness or vertigo. When tested, many people with PD experience vestibular dysfunction (balance issues related to the inner ear) even without having symptoms of vertigo or dizziness.
