Summary
Many familial hemiplegic migraine (FHM) patients report migraine triggers, with stress and light being common. One-third of FHM patients experience triggers that often or always cause attacks, similar to migraine with aura triggers.
Area of Science:
- Neurology
- Genetics
- Epidemiology
Background:
- Familial hemiplegic migraine (FHM) is a rare subtype of migraine with aura.
- Understanding FHM triggers is crucial for patient management and quality of life.
Purpose of the Study:
- To identify and characterize migraine trigger factors in a population-based sample of FHM patients.
- To differentiate triggers for hemiplegic migraine (HM) attacks versus migraine with aura (MA) or without aura (MO) within FHM patients.
Main Methods:
- A questionnaire detailing 16 potential trigger factors was administered to 127 FHM patients.
- Patients distinguished between HM, MA, and MO attacks in relation to reported triggers.
Main Results:
- The study achieved a 59% response rate (75/127), with 76% (57/75) experiencing current HM attacks.
- 63% (47/75) reported at least one trigger for HM, and 36% (27/75) identified triggers that frequently or always induced attacks.
- Common triggers included stress, bright light, emotional influences, and sleep disturbances; these align with typical MA triggers.
Conclusions:
- A significant proportion of FHM patients identify trigger factors for their attacks.
- One-third of FHM patients report consistent triggers, which are similar to those for MA.
- Patient education on avoiding identified triggers is recommended, though the role of triggers in initial FHM attacks requires further investigation.

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...
01:26Transient 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...
01:19Encephalitis l: Introduction
Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
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...
01:15Ischemic 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.
01:26Encephalitis ll: Pathophysiology
Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...
