Parkinson’s Disease is a progressive neurological condition, which is characterised by both motor (movement) and non-motor symptoms.
The four diagnostic symptoms of PD are: tremor, bradykinesia (slowness of voluntary movements), muscle rigidity and postural instability. Other symptoms may include loss of smell, constipation, slowness in thinking, depression, fatigue, changes in speech fluency, micrographia (small handwriting), decrease in speech volume, sleep disturbances and swallowing changes.
