Vascular parkinsonism (VP) is a form of parkinsonism that arises due to cerebrovascular disease, leading to motor and non-motor symptoms similar to those seen in Parkinson's disease (PD). Understanding the clinical presentation, signs, symptoms, and patient characteristics associated with ICD-10 code G21.4 is crucial for accurate diagnosis and management.

Clinical Presentation

Vascular parkinsonism typically presents with a combination of motor and non-motor symptoms. The onset is often insidious, and the symptoms can vary significantly among patients.

Motor Symptoms

1. Bradykinesia: This is a hallmark symptom characterized by slowness of movement. Patients may experience difficulty initiating movements and may exhibit a shuffling gait.
2. Rigidity: Increased muscle tone can lead to stiffness, which may affect the arms and legs, contributing to a stooped posture.
3. Postural Instability: Patients often have balance issues, increasing the risk of falls.
4. Tremor: While tremor is less common in vascular parkinsonism compared to idiopathic Parkinson's disease, some patients may still exhibit resting tremors.

Non-Motor Symptoms

1. Cognitive Impairment: Many patients experience cognitive decline, which can range from mild cognitive impairment to vascular dementia.
2. Mood Disorders: Depression and anxiety are prevalent among individuals with vascular parkinsonism, often exacerbating the overall clinical picture.
3. Autonomic Dysfunction: Symptoms such as orthostatic hypotension, urinary incontinence, and constipation may occur due to autonomic nervous system involvement.

Signs and Symptoms

The signs and symptoms of vascular parkinsonism can be categorized into primary and secondary features:

Primary Features

• Gait Disturbances: Patients may exhibit a broad-based gait, difficulty turning, and a tendency to freeze while walking.
• Facial Masking: Reduced facial expressiveness can be observed, similar to that seen in Parkinson's disease.
• Reduced Arm Swing: Patients may show diminished movement of the arms while walking.

Secondary Features

• Fatigue: Many patients report significant fatigue, which can impact daily activities.
