This review provides an overview of the clinical features of Parkinson's disease (PD), both motor and non-motor, and discusses major treatment strategies and their complications. PD is a progressive, multi-system neurodegenerative disorder that affects individuals primarily in later life, with a prevalence of about 0.3% of the population and increasing with age. The disease is characterized by the formation of Lewy bodies and Lewy neurites in the brain, leading to the degeneration of dopaminergic neurons in the substantia nigra. Motor symptoms, such as bradykinesia, muscle rigidity, resting tremor, and postural instability, are typically the first to appear. Non-motor symptoms, including autonomic dysfunction, sleep disturbances, cognitive and psychiatric issues, and sensory symptoms, often precede motor symptoms and can significantly impact the quality of life. Treatment with dopaminergic drugs, such as levodopa, is symptomatic and aims to correct motor disturbances, but it can also induce complications like dyskinesias. Surgical therapy, such as deep brain stimulation, is an option for some patients when medical therapy fails. The clinical course of PD is variable, with early symptoms often unilateral and mild, but as the disease progresses, symptoms worsen and non-motor symptoms become more prevalent, leading to increased dependency and reduced quality of life. Despite advancements in treatment, no effective disease-modifying therapies have been identified.This review provides an overview of the clinical features of Parkinson's disease (PD), both motor and non-motor, and discusses major treatment strategies and their complications.
