Early symptoms of Parkinson's disease include small handwriting; tremors; voice changes; sleep problems; feeling slow and stiff in the morning; small changes in posture; and masking, states Healthline. Early symptoms are mild and occur gradually. However, some of these symptoms do not occur in people with Parkinson’s disease, explains WebMD.
Changes in the brain of people with Parkinson’s make it hard to control fine movements, such as in writing, according to WebMD. Their handwriting has closely spaced words. Masking is the absence of facial expression, which results from the inability to control small facial muscles. Tremors start as a slight shaking or twitching of the hand, finger or foot. It is a common and recognizable symptom for people with Parkinson’s, and these tremors worsen as the disease progresses.
Rigidity of limbs and slow movements appear early in Parkinson’s. Impairment of the nerves that control movement is the cause of uncoordinated movements. Voice changes in early stages of the disease are less dramatic and people often speak in hoarse voices or low tones, notes Healthline. Parkinson’s generally affects people older than 60 and may cause anxiety and depression. The severity of symptoms in Parkinson’s varies, and in early stages, these symptoms commonly occur on one limb or one side of the body, states WebMD. As the disease worsens, it interrupts daily activities.
