Summary
Chronic pain, or novel pain, is more common after stroke than in the general population. Stroke survivors experiencing new pain were younger and more likely to be depressed.
Area of Science:
- Neurology
- Pain Medicine
- Epidemiology
Background:
- Chronic pain is a recognized complication following stroke.
- Understanding the incidence and characteristics of new-onset pain post-stroke is crucial.
Purpose of the Study:
- To determine the prevalence and types of new chronic pain in stroke patients.
- To compare this prevalence with a matched general population reference group.
- To identify factors associated with pain development after stroke.
Main Methods:
- A population-based follow-up study design was employed.
- Questionnaires assessed new chronic pain development two years post-stroke in 608 patients and 519 controls.
- Data were collected from a Danish national stroke database.
Main Results:
- 39.0% of stroke patients developed new chronic pain compared to 28.9% in the reference group (OR 1.57).
- Factors associated with post-stroke pain included younger age and depression.
- Stroke patients more frequently reported novel headache, shoulder pain, and muscle stiffness pain.
Conclusions:
- Stroke patients have a significantly higher incidence of developing new chronic pain.
- Post-stroke pain assessment should be integrated into routine stroke follow-up care.

01:15Ischemic Stroke l: Introduction
Ischemic stroke is an acute cerebrovascular condition in which blood flow to a brain region is suddenly interrupted, leading to tissue infarction. Neurons depend on continuous oxygen and glucose supply, so even brief reductions in perfusion cause energy failure, ionic imbalance, and irreversible injury. Ischemic strokes are classified into thrombotic and embolic types based on their underlying mechanisms.Thrombotic MechanismsThrombotic stroke develops when a clot forms within a cerebral artery.
01:15Ischemic Stroke ll: Pathophysiology
An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...
01:17Hemorrhagic Stroke l: Introduction
A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...
01:29Hemorrhagic Stroke ll: Pathophysiology
A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
01:29Stroke: Introduction and Types
A stroke is an acute neurological event caused by the sudden disruption of cerebral blood flow, leading to rapid loss of neuronal function. Neurons depend on continuous oxygen and glucose supply, so even brief interruptions can cause irreversible injury within minutes. Strokes are classified into ischemic and hemorrhagic types.Ischemic StrokeIschemic strokes are most common and occur due to arterial occlusion, depriving brain tissue of oxygen and nutrients. This leads to energy failure, ionic...
