What are the demographics of people with Parkinson's Disease?

There are some people who have autistic traits or have autism. They can look normal, attend school normally and go to work as per normal. However, they might be more sensitive to changes in colour, texture and sounds. These people might also experience meltdowns more frequently. Sometimes, they are just "not happy" and are unable to express their feelings, or even realise that they are not happy until the meltdown. These conditions can be diagnosed by a psychologist or psychiatrist trained in autism.

The signs and symptoms of Parkinson disease can vary for each individual. They can be mild, especially in the very early stages. Over time, the important cardinal signs of Parkinson disease develop initially on one side of the body before progressing to affect both sides. These are shaking (tremors), stiffness (rigidity) and slowness of movement (bradykinesia). The tremors often start in the limb, most noticeably in the hand. A key feature is that the tremor in the hand happens when the hand is resting. This is also known as a rest tremor occurring at 4-6Hz.
