Initial treatment for Parkinson's disease

No known treatment can stop or reverse the breakdown of nerve cells that causes Parkinson's disease. However, drugs can relieve many symptoms of the disease. Surgery also can be effective in a small number of people to treat symptoms of Parkinson's disease.

Treatment is different for every person, and the type of treatment you will need may change as the disease progresses. Your age, work status, family, and living situation can all affect decisions about when to begin treatment, what types of treatment to use, and when to make changes in treatment. As your medical condition changes, you may need regular adjustments in your treatment to balance quality-of-life issues, side effects of treatment, and treatment costs.

Parkinson's disease causes a wide range of symptoms and complications. This topic covers the overall management of the disease. This topic does not discuss managing specific symptoms.
Initial treatment

If your symptoms are mild, you may not need treatment for Parkinson's disease. Your doctor may wait to prescribe treatment with drugs until your symptoms begin to interfere with your daily activities. Additional treatment methods (such as exercise, physical therapy, and occupational therapy) can be helpful at all stages of Parkinson's disease to help you maintain your strength, mobility, and independence.

If you do need drugs at this point, there are several options. Levodopa is considered the "gold standard" of treatment for Parkinson's disease. But levodopa can have negative effects when used long-term. Because of this, dopamine agonists such as pramipexole and ropinirole often are used first. Other non-dopamine drugs may be used early in the course of the disease. These include amantadine, monoamine oxidase inhibitors (such as selegiline), and anticholinergics (such as trihexyphenidyl). As the disease progresses, levodopa will likely need to be added.

Early in the disease, it might be helpful to take pills with food to help with nausea, which may be caused by some medicines taken for Parkinson's disease. Later in the disease, taking the medicines at least one hour before meals (and at least two hours after meals) may help them work better.

Your doctor, other health professionals, or Parkinson's disease support groups can help you get emotional support and education about the illness. This is important both early and throughout the course of the disease.
Ongoing treatment

As Parkinson's disease progresses, the symptoms usually become more disabling. Most people develop mild to moderate tremor. Movement is often slow and limited due to muscular rigidity and the slowing down and loss of automatic and spontaneous movement (bradykinesia). Treatment in this stage is determined by weighing the severity of the symptoms against the side effects of drugs.

The symptoms of Parkinson's disease change as the disease progresses. Because of this, your doctor will adjust your drugs to deal with the symptoms as they appear. Levodopa is the most commonly used drug for Parkinson's disease. However, it may cause side effects with prolonged use or high dosages. Your doctor may prescribe dopamine agonists such as pramipexole or ropinirole to delay the point at which you need to begin taking levodopa. Studies have suggested that this may delay the onset of levodopa's side effects.234 Your doctor may also prescribe levodopa along with a dopamine agonist.
