Feeling dizzy or fainting can be a sign of low blood pressure and can be linked to Parkinson’s disease, as can speaking more softly or you seem to be stooping, leaning or slouching when you stand.
The charity also says each person may experience them differently and the order and severity of these symptoms can vary from person to person.
Parkinson’s UK says: “Some people with Parkinson’s may experience hallucinations or delusions.“
They usually happen as a side effect of your Parkinson’s medication. But in some cases they may be a symptom of your Parkinson’s, or another condition, such as dementia.”
