The early symptoms of Parkinson's disease primarily include weakness of limbs on one side, resting tremors, and bradykinesia, among others. As the disease progresses, patients will display typical Parkinson's symptoms, including a shuffling gait, reduced facial expressions, decreased sense of smell, orthostatic hypotension, anxiety and depression, cognitive decline, constipation, frequent urination, etc. Therefore, when these symptoms appear, the possibility of Parkinson's disease should be considered. Patients need to promptly visit the neurology department of a hospital for complete testing such as routine blood tests, urinalysis, MRI of the skull, and if necessary, cerebrospinal fluid analysis through lumbar puncture to confirm the diagnosis. Once diagnosed, treatment with anti-Parkinson's medication should be started as soon as possible. Commonly used medications include Levodopa, dopamine receptor agonists, monoamine oxidase inhibitors, Vitamin B6, and more.
