The Parkinson's Disease Society has congratulated NHS Scotland for creating a new guideline to reduce the risk of misdiagnosis of the condition by GPs.
Last week, the Scottish Intercollegiate Guidelines Network (Sign) ruling recommends that people with suspected Parkinson's should be diagnosed and get continual care from a consultant with expertise in motor disorders, as opposed to a GP.
There has been a large amount of "disturbing evidence" highlighted by Sign that GPs and hospital doctors are not familiar enough with Parkinson's disease to tell it from other conditions.
GPs "shouldn't be expected to manage such a complex condition alone", said Dr Kieran Breen of the Parkinson's Disease Society.
He added: "We hope that this guideline will make all health professionals aware that referral for expert diagnosis and management of Parkinson's will mean the best care for patients."
Parkinson's disease is caused by a loss of nerve cells in the part of the brain known as the substantia nigra, which are responsible for producing dopamine.
