Parkinsonism
Introduction
Parkinsonism refers to symptoms of Parkinson disease (such as slow movements and tremors) that are caused by another condition. Parkinsonism is caused by brain disorders, brain injuries, or certain drugs and toxins. People with parkinsonism, like those with Parkinson Disease (PD) , have tremors that occur when muscles are relaxed, stiff muscles, slow movements, and problems with balance and walking. Doctors try to identify the cause of parkinsonism by asking about conditions known to cause it and by using brain imaging to look for a possible cause. The cause is treated if possible, drugs may be used to relieve symptoms, and general measures (such as simplifying daily tasks) may help people function better.
