Insights

A stroke affecting the left middle cerebral artery caused aphasia and apraxia in a 74-year-old man. Carotid endarterectomy improved his left limb-kinetic apraxia, suggesting a link between carotid stenosis and this rare neurological symptom.

Area of Science:

  • Neurology
  • Cerebrovascular Medicine
  • Neuroscience

Background:

  • A 74-year-old male presented with aphasia and right upper extremity weakness, indicative of a left middle cerebral artery (MCA) infarct.
  • Cerebral angiography revealed significant bilateral proximal internal carotid artery stenosis with plaque formation.

Observation:

  • The patient exhibited left limb-kinetic apraxia, a rare motor disorder.
  • Following carotid endarterectomy of the left carotid artery, a notable improvement in left limb-kinetic apraxia was observed.

Findings:

  • The study links left MCA infarct and severe carotid stenosis to the development of left limb-kinetic apraxia.
  • Post-operative improvement suggests a causal relationship or significant contributing factor of carotid artery disease to the apraxia.

Implications:

  • This case highlights the potential for cerebrovascular disease, specifically carotid stenosis, to manifest as unusual neurological deficits like limb-kinetic apraxia.
  • Understanding this association may improve diagnostic approaches and treatment strategies for patients with complex stroke presentations and carotid artery disease.

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.
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...
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...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
