Restless Leg Syndrome
Restless legs syndrome (RLS) is a common condition that affects many people with Parkinson’s disease. It is characterized by an overwhelming urge to move the legs, which is often accompanied by uncomfortable sensations such as tingling, burning, or crawling. RLS can cause significant sleep disturbances, which can in turn worsen other symptoms of Parkinson’s disease. When dopamine levels are low, it can lead to a range of motor symptoms, including tremors and stiffness, as well as non-motor symptoms such as sleep disturbances, depression, and anxiety. RLS may be related to dopamine dysfunction in the brain, although the exact mechanisms are not well understood. Additionally, RLS may be caused by other factors such as iron deficiency, peripheral neuropathy, or medications used to treat Parkinson’s disease.
