The traditional view of Parkinson's disease is shifting to reflect growing awareness that it is much more than a motor disease. Many non-motor components and their treatments are now under study. The following symptoms should be carefully monitored by physicians and caregivers:

• Depression is the most common psychiatric problem associated with PD, affecting about 40% of patients. Because depression is a common problem in older people, it is likely not to be recognized as a symptom.
• Anxiety affects about 30% of patients.
• Dementia and paranoia are more common than previously understood.
• Compulsive behavior -- 2004 studies found that patients with PD may have a significant tendency (up to 20%, as compared to 2% in the general population) to engage in compulsive problem gambling and sexual behaviors. The internet can provide access to such activities.
• Orthostatic hypotension -- some patients experience a sudden drop in blood pressure when they stand. This can cause dizziness and fainting.
• Changes in sensations of temperature, hot flashes, and excessive sweating.
• Daytime sleepiness and other sleep disorders are common.
