Parkinsons Disease

The symptoms of Parkinson's disease usually develop gradually and aremild at first.

There are many different symptoms associated with Parkinson's disease. Some of the more common symptoms are described below.

However,the order in which these develop and their severity is different for each individual.It's unlikely thata personwith Parkinson's disease would experience all ormost of these.

Main symptoms

The three main symptoms of Parkinson's disease affect physical movement:

• tremor shaking, which usually begins in the hand or arm and is more likely to occur when the limb is relaxed andresting
• slowness of movement (bradykinesia) where physical movements are much slower than normal, which can make everyday tasks difficult and can result in a distinctive slow, shuffling walk with very small steps
• muscle stiffness (rigidity) stiffness and tension in the muscles, which can make it difficult to move around and make facial expressions, and can result in painful muscle cramps (dystonia)

These mainsymptoms are sometimes referred to by doctors as parkinsonism as there can be causes other than Parkinson's disease.
