Tremor II: Parkinson disease in the differential diagnosis of tremor
As Parkinson’s disease is the second most common cause of tremor in adults which may cause significant disability and decreased quality of life, these patients need continuous close monitoring and support. Prevalence of Parkinson’s disease in people over the age of 85 is approximately 4-5%. Diagnosis can be made with the presence of any two symptoms out of bradykinesia, rigidity, postural instability and rest tremor. Depression, dementia and psychosis are other problems associated with Parkinson’s disease. In the early stage of the disease, patients are treated with levodopa or dopamin agonists. Young patients and the patients with moderate symptoms are preferably treated with dopamine agonists and levodopa is preferred in older patients. Approximately 40% of the patients who are treated with levopoda develop motor disability and dyskinesia in five years. As Parkinson’s disease progresses, the patients’ ability to perform daily activities decreases. The exercise therapy has many benefits beside medical treatment to prevent muscular atrophy and contracture. Besides, the patients should be recommended to adopt changes to ease daily activities.
