Abstract

Insights

This case study reports a rare instance of migraine-induced epistaxis with aura, highlighting the potential for bilateral brain involvement during migraine aura. Further investigation into guided anamnesis is suggested for similar cases.

Area of Science:

  • Neurology
  • Neuroscience

Background:

  • Epistaxis and migraine have been anecdotally linked since the 19th century.
  • Sporadic hemiplegic migraine is a rare subtype characterized by reversible motor deficits.
  • Few contemporary cases link epistaxis and migraine, particularly with aura.

Observation:

  • A 47-year-old male experienced epistaxis during the resolution phase of migraine with scintillating scotoma.
  • He later developed complex auras with transient aphasia and hemiplegia, inconsistent with typical neurological findings.
  • Genetic testing for common migraine-related mutations was negative.

Findings:

  • This is the first reported case of migraine-induced epistaxis associated with aura.
  • The complex aura's topography suggests bilateral, uneven, and selective spreading depression.
  • Late-onset complex auras may indicate interactions between genetic predisposition and environmental factors.

Implications:

  • Highlights the importance of detailed patient history (anamnesis) in identifying rare migraine presentations.
  • Suggests a broader understanding of migraine aura pathophysiology, potentially involving bilateral cortical spreading depression.
  • Emphasizes the need to consider complex environmental and genetic interactions in late-onset neurological disorders.

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...
Epistaxis01:30

Epistaxis

Epistaxis, or nosebleeds, occurs when small, swollen blood vessels in the nasal mucous membrane rupture. Typically, the anterior septum is the primary site of occurrence.
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...
Hemorrhagic Stroke ll: Pathophysiology01:29

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...
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...
Increased Intracranial Pressure ll: Pathophysiology01:29

Increased Intracranial Pressure ll: Pathophysiology

Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
