Vascular parkinsonism
ICD-10 G21.4 is a billable code used to indicate a diagnosis of vascular parkinsonism.
Vascular parkinsonism is a form of parkinsonism that arises from cerebrovascular disease, particularly the presence of multiple small strokes or significant vascular changes in the brain. Unlike idiopathic Parkinson's disease, which is primarily linked to the degeneration of dopaminergic neurons in the substantia nigra, vascular parkinsonism is characterized by motor symptoms that may include bradykinesia, rigidity, and postural instability, often accompanied by gait disturbances. Patients may also exhibit cognitive impairment and other non-motor symptoms due to underlying vascular pathology. The clinical presentation can vary significantly, and symptoms may not respond as well to dopaminergic medications compared to idiopathic Parkinson's disease. Diagnosis typically involves neuroimaging to identify vascular lesions and a thorough clinical assessment to differentiate from other extrapyramidal disorders. Understanding the vascular contributions to parkinsonism is crucial for effective management and treatment planning.
Detailed neurological examination findings, neuroimaging results, and treatment response.
Patients presenting with gait disturbances, rigidity, and cognitive decline.
Ensure clear documentation of vascular risk factors and any cognitive assessments.
Comprehensive assessment of functional status and comorbidities.
Older adults with a history of strokes presenting with parkinsonian symptoms.
Focus on the impact of vascular health on overall mobility and independence.
Used for follow-up visits for patients with vascular parkinsonism.
Document history, examination, and medical decision-making.
Neurologists should focus on neurological assessments and treatment adjustments.
Vascular parkinsonism is primarily caused by cerebrovascular disease, leading to motor symptoms that may not respond well to dopaminergic medications, unlike idiopathic Parkinson's disease, which is due to neurodegeneration.
