What is Parkinson’s disease?
Parkinson’s disease (Parkinsonism) is marked by the presence of certain recognizable symptoms. These include uncontrollable shaking or tremor, lack of coordination, and speaking difficulties. However, symptoms vary and may worsen as the disease progresses.
The main symptoms of Parkinson’s include:
uncontrollable shaking and tremors
slowed movement (bradykinesia)
balance difficulties and eventual problems standing up
stiffness in limbs
Many doctors who diagnose this brain disorder rely on the Hoehn and Yahr rating scale to classify the severity of symptoms. The scale is broken into five stages based on disease progression. The five stages help doctors evaluate how far the disease has advanced.
Stage 1 is the mildest form of Parkinson’s. At this stage, there may be symptoms, but they’re not severe enough to interfere with daily tasks and overall lifestyle. In fact, the symptoms are so minimal at this stage that they’re often missed. But family and friends may notice changes in your posture, walk, or facial expressions.
A distinct symptom of stage 1 Parkinson’s is that tremors and other difficulties in movement are generally exclusive to one side of the body. Prescribed medications can work effectively to minimize and reduce symptoms at this stage.
Stage 2 is considered a moderate form of Parkinson’s, and the symptoms are much more noticeable than those experienced in stage 1. Stiffness, tremors, and trembling may be more noticeable, and changes in facial expressions can occur.
While muscle stiffness prolongs task completion, stage 2 does not impair balance. Difficulties walking may develop or increase, and the person’s posture may start to change.
People at this stage feel symptoms on both sides of the body (though one side may only be minimally affected) and sometimes experience speech difficulties.
The majority of people with stage 2 Parkinson’s can still live alone, though they may find that some tasks take longer to complete. The progression from stage 1 to stage 2 can take months or even years. And there is no way to predict individual progression.
