Parkinson’s syndrome refers to a group of movement disorders caused by various causes other than idiopathic Parkinson’s disease, including tremor, muscle rigidity, bradykinesia and postural balance disorders similar to Parkinson’s disease, including secondary Parkinson’s syndrome, hereditary Parkinson’s syndrome and Parkinson’s superposition syndrome. Secondary Parkinson’s syndrome refers to a group of diseases with clinical manifestations such as tremor, muscle rigidity, motor retardation and postural balance disorders caused by degeneration and necrosis of dopaminergic neurons in the brain secondary to infectious diseases such as encephalitis, drugs or toxic diseases such as neuroleptics or carbon monoxide, vascular diseases such as multiple cerebral infarction, or cranial trauma diseases. Hereditary Parkinson’s syndrome is a group of movement disorders with Parkinson’s-like manifestations caused by a genetic cause. These include autosomal dominant Lewy’s disease, Huntington’s disease, hepatomegaly, and spinal cerebellar ataxia. Parkinson’s symptoms associated with these diseases are often characterized by rigidity and hypokinesia, and resting tremor is rare; most of the symptoms begin with bilateral limbs at the same time, and treatment is mostly insensitive to levodopa. Parkinson’s superimposed syndrome, also known as multiple systemic lesions, is a group of neurodegenerative diseases with clinical symptoms of Parkinson’s disease and pathology showing different histological features. For example, Parkinson’s syndrome-dementia-amyotrophic lateral sclerosis complex, progressive supranuclear palsy, multisystem atrophy or degeneration, etc. The clinical symptoms are atypical, and in addition to Parkinson’s disease-like manifestations, there may be multiple neurological lesions in the cerebellum, cortex, and pyramidal tract, etc. The diagnosis of Parkinson’s superimposed syndrome can be considered after excluding other multisite encephalopathies. The diagnosis of Parkinson’s superposition syndrome can be made after excluding other multi-location brain diseases. In conclusion, in addition to primary Parkinson’s disease, we should be alert to Parkinson’s syndrome caused by various etiologies of movement disorders such as tremor and muscle rigidity, especially for those with young age, other systemic lesions, atypical motor symptoms and poor effect of levodopa treatment.
