Parkinson’s clinical symptoms can be categorized into motor and non-motor symptoms, such as resting tremor, myotonia, bradykinesia, and sensory deficits. Parkinson’s motor symptoms include resting tremor, myotonia, dyskinesia, and postural gait disturbances. The motor symptoms usually start from one side of the upper limb, then involve the lower limb of the same side, and then spread to the opposite side of the upper limb and lower limb, in an “N” shape. Resting tremor is usually the first manifestation, starting from the distal end of one side of the upper limb, which is obvious when the limb is at rest, and is reduced when the patient initiates random movements. Non-motor symptoms of Parkinson’s include sensory, autonomic, psychiatric and cognitive deficits. Early onset of Parkinson’s disease may be characterized by decreased sense of smell and sleep disorders, especially behavioral abnormalities during rapid eye movement (REM) sleep. If the above symptoms occur, you should immediately go to the neurology department of your local hospital and follow the doctor’s instructions for treatment.
