Early Signs of Parkinson's Disease

If you know anyone who has been diagnosed with Parkinson's disease you'll have noticed the obvious symptoms such as tremors, slow movement and speech.

Scientists at the University of Sydney's Brain and Mind Institute believe there are earlier indicators such as mood changes, loss of the sense of smell, constipation and a condition known as Rapid Eye Movement Sleep Behaviour Disorder.

However, they may not be the early indicators of this debilitating neurological condition.

Simply put, this is when a person starts "acting out" in their dreams, kicking or punching the person sharing their bed.

A person with Parkinson's disease lacks the dopamine that inhibits this behaviour during sleep, and as such researchers think it's an early indicator of the condition.

Drive presenter Kelly Higgins-Devine spoke with Dr Simon Lewis, Neurologist and Senior lecturer in Cognitive Neuroscience about these early warning signs.
