Recognizing the Signs of Vascular Parkinsonism
At a Glance
Vascular parkinsonism usually causes symmetric, lower-body walking and balance problems, early falls, and less tremor than typical Parkinson’s disease. Cognitive or urinary changes may occur early, and sudden neurological changes require a 911 call.
While idiopathic Parkinson’s disease typically begins with a tremor in one hand, vascular parkinsonism (VaP) often presents as a “lower-body” disorder [1][2]. Understanding these symptoms can help you and your care team differentiate between the typical aging process, traditional Parkinson’s, and the specific challenges of vascular-related movement issues.
The Hallmark: Lower-Body Parkinsonism
The most defining feature of VaP, especially the gradual (insidious) type, is a significant disconnect between how your legs move and how your arms move [3].
- Symmetry from the Start: Unlike idiopathic Parkinson’s, which usually begins on one side of the body, VaP symptoms often appear on both sides at the same time [1][2].
- Gait and Balance: You may experience a “shuffling” gait, where steps are short and the feet barely leave the ground. This is sometimes called a magnetic gait because it feels as though the feet are stuck to the floor [2].
- Early Falls: Balance problems and falls often occur very early in the course of VaP [1]. In traditional Parkinson’s, frequent falls usually don’t happen until the disease has progressed for many years.
- Lack of Tremor: While a resting tremor is the classic sign of Parkinson’s, it is much less common in VaP [3][2]. Instead, you are more likely to feel a general stiffness (rigidity) and slowness of movement (bradykinesia) primarily in your legs [3].
Accompanying Symptoms (Non-Motor)
Because VaP is caused by damage to the brain’s blood vessels, it often affects areas beyond those responsible for movement. These “non-motor” symptoms can sometimes appear even before the walking difficulties become obvious.
- Cognitive Changes: Vascular-related memory issues or executive dysfunction (difficulty planning, organizing, or multi-tasking) are common and may occur earlier than in traditional Parkinson’s [2][3].
- Urinary Symptoms: Early and prominent urinary urgency or incontinence (loss of bladder control) is a frequent companion to the gait issues in VaP [1][2].
- Pseudobulbar Signs: You may notice “emotional incontinence,” where you experience sudden, uncontrollable bursts of crying or laughing that don’t match how you actually feel [1].
- Speech and Swallowing: Changes in voice (slurring) or difficulty swallowing (dysphagia) can also occur as the vascular damage affects the nerves controlling the mouth and throat [4].
Recognizing Emergencies: When to Seek Immediate Care
Because VaP is driven by vascular events, people living with this condition are at a higher risk for new strokes. It is vital to distinguish between a routine bad day and a medical emergency.
Call 911 for Sudden Neurological Changes
If any of the following symptoms appear suddenly (over seconds or minutes), note the exact time you were last known to be well and call emergency services immediately (911 in the US). Do not drive yourself to the hospital and do not wait to see if the symptoms improve, even if they seem to go away (like in a Transient Ischemic Attack or TIA) [5][6]:
Use the BE-FAST acronym to recognize common stroke signs:
- B - Balance: Sudden loss of balance, sudden inability to stand or walk, or sudden new freezing.
- E - Eyes: Sudden loss of vision, double vision, or blurred vision in one or both eyes.
- F - Face: One side of the face droops or feels numb.
- A - Arm: Sudden weakness or numbness in one arm or leg, especially if it is only on one side of the body.
- S - Speech: Sudden trouble speaking, slurred speech, or difficulty understanding others.
- T - Time: Call emergency services immediately [7].
Other Urgent Symptoms:
Not all emergencies fit the BE-FAST acronym. You should also seek urgent medical assessment for:
- A new, severe, or sudden headache.
- A seizure.
- Sudden confusion or delirium.
- A significant and rapid decline in your ability to move or think over hours or days, especially if accompanied by a fever or signs of infection (like a UTI or pneumonia), as this could indicate an infection, delirium, or medication toxicity.
Always report unexplained rapid changes to your clinician the same day.
