Insights

Haemorrhagic pure motor stroke (PMS) is rare, affecting younger patients and often presenting with headache. Differentiating it from ischemic stroke is crucial for appropriate treatment.

Area of Science:

  • Neurology
  • Stroke Medicine
  • Neuroimaging

Background:

  • Pure motor stroke (PMS) is a subtype of stroke affecting motor pathways.
  • Haemorrhagic PMS is a rare variant, distinct from ischemic PMS.
  • Understanding its characteristics is vital for diagnosis and management.

Purpose of the Study:

  • To delineate the clinical features of haemorrhagic pure motor stroke (PMS).
  • To compare haemorrhagic PMS with ischemic PMS and other intracerebral hemorrhages.
  • To identify distinguishing clinical markers for haemorrhagic PMS.

Main Methods:

  • Retrospective analysis of 12 patients with haemorrhagic PMS.
  • Comparison with a database of ischemic PMS (n=380) and intracerebral hemorrhage (n=364).
  • Statistical analysis of demographic, clinical, and radiological data.

Main Results:

  • Haemorrhagic PMS constituted 3.2% of pure motor hemiparesis and 3.3% of intracerebral hemorrhages.
  • Patients with haemorrhagic PMS were younger and more likely to report headache and thalamic involvement compared to ischemic PMS.
  • Haemorrhagic PMS showed less nausea, vomiting, altered consciousness, sensory symptoms, and ventricular hemorrhage than other intracerebral hemorrhages.

Conclusions:

  • Haemorrhagic PMS is an uncommon stroke subtype with unique clinical characteristics.
  • Headache at onset may help distinguish haemorrhagic PMS from other lacunar strokes.
  • Significant differences exist between haemorrhagic PMS and other intracerebral hemorrhages, necessitating tailored clinical approaches.

Hemorrhagic 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...
Hemorrhagic Stroke l: Introduction01:17

Hemorrhagic 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...

Stroke: 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...
Ischemic Stroke ll: Pathophysiology01:15

Ischemic 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...
Ischemic Stroke l: Introduction01:15

Ischemic 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.
Transient Ischemic Attack l: Introduction01:26

Transient Ischemic Attack l: Introduction

A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...
