1. PARKINSON’S DISEASE LUKE CARROLL & LAUREN DESROCHES

2. DESCRIPTION Parkinson's disease is a disorder of the brain that leads to shaking (tremors) and difficulty with walking, movement, and coordination.

3. PARTS OF NERVOUS SYSTEM AFFECTED Brain - Nerve cells use a brain chemical called dopamine to help control muscle movement. Parkinson's disease occurs when the nerve cells in the brain that make dopamine are slowly destroyed. Without dopamine, the nerve cells in that part of the brain cannot properly send messages. This leads to the loss of muscle function.

4. CAUSE OF CONDITION Parkinson's disease most often develops after age 50. It is one of the most common nervous system disorders of the elderly. Sometimes Parkinson's disease occurs in younger adults. It affects both men and women. In some cases, Parkinson's disease runs in families. When a young person is affected, it is usually because of a form of the disease that runs in families.

5. THERAPY Dopamine therapy (drugs) Physical therapy, speech therapy, and occupational therapy Railings or banisters placed in commonly used areas of the house. Other changes may be needed around the home to prevent falls and make the bathroom safe. Deep brain stimulation involves placing electrical stimulators in specific areas of the brain that control movement. Another type of surgery destroys brain issues that cause Parkinson's symptoms. Stem cell transplant and other clinical trials are currently ongoing in the USA

6. PHARMACOLOGY Current treatments for Parkinson's are designed to increase dopamine by using levodopa (Sinemet or Madopar), which is converted in the brain into dopamine, or drugs that mimic dopamine (dopamine agonists). Memantine, rivastigmine, galantamine for cognitive difficulties Antidepressants for mood disorders Gabapentin, duloxetine for pain Fludrocortisone, midodrine, botox, sidenafil for autonomic dysfunction Armodafinil, clonazepam, zolpidem for sleep disorders

7. PROGRESSION Untreated, the disorder will get worse until a person is totally disabled. Parkinson's may lead to a deterioration of all brain functions, and an early death. Most people respond to medications. How much the medications relieve symptoms, and for how long can be very different in each person. The side effects of medications may be severe
