This weakness typically precedes or accompanies the severe headache phase and can last from minutes to several hours, or even days in some cases. Unlike regular migraines where aura usually involves visual disturbances (flashing lights, blind spots), hemiplegic migraine involves motor aura - weakness that can range from mild clumsiness to complete paralysis on one side. The condition can be familial (inherited) or sporadic (occurring without family history). It requires careful evaluation to distinguish from other serious conditions like stroke. At Healers Clinic, we approach hemiplegic migraine by accurately diagnosing the condition, identifying triggers, providing both acute and preventive treatment, and offering integrative support. ### At-a-Glance Overview **What is Hemiplegic Migraine?** Hemiplegic migraine is a rare variant of migraine with aura characterized by transient motor weakness or paralysis on one side of the body as part of the aura phase. The word "hemiplegia" literally means "half paralysis," reflecting the one-sided nature of this symptom. During a hemiplegic migraine attack, the aura phase (which typically precedes the headache) includes not only visual and sensory disturbances common in typical migraine with aura but also motor symptoms. This motor aura can be particularly frightening as it mimics stroke symptoms. The weakness can affect the face, arm, leg, or combination, and may be accompanied by speech difficulties, sensory changes, and confusion. The underlying mechanism involves abnormal brain activity causing changes in blood flow and cortical spreading depression, similar to other migraine auras but affecting motor pathways. **Who Experiences Hemiplegic Migraine?** Hemiplegic migraine is rare, affecting approximately 1 in 10,000 people. It typically begins in childhood or adolescence, often before age 20, though it can occur at any age. Both males and females can be affected, though there may be a slight female predominance. The familial form is inherited in an autosomal dominant pattern, meaning a parent with the condition has a 50% chance of passing it to each child. Several genes have been identified (CACNA1A, ATP1A2, SCN1A) that cause familial hemiplegic migraine. The sporadic form occurs in individuals without family history, often due to new genetic mutations. In our Dubai practice, we see patients seeking evaluation for concerning "stroke-like" headaches that ultimately prove to be hemiplegic migraine. **How Long Do Hemiplegic Migraine Attacks Last?** The duration of hemiplegic migraine aura varies significantly between individuals and between attacks. Motor weakness typically lasts between 1 hour to 72 hours, though some attacks may be shorter or longer. The headache phase that follows or accompanies the aura can last from 4 hours to several days. Unlike typical migraines where aura lasts minutes, the motor aura in hemiplegic migraine can be prolonged. With treatment, the duration and severity of attacks can often be reduced. Between attacks, patients are typically completely normal with no residual weakness. **What's the Outlook?** While hemiplegic migraine can be severe and frightening, most patients have a good prognosis with appropriate management. Attacks tend to decrease in frequency with age in many individuals. The key is accurate diagnosis, trigger avoidance, appropriate acute treatment, and preventive therapy when needed. At Healers Clinic, our comprehensive approach helps patients understand their condition, avoid triggers, and achieve good control. ---

Definition & Terminology

Formal Definition

### Formal Medical Definition Hemiplegic migraine is defined as a subtype of migraine with aura in which the aura includes motor weakness. According to the International Classification of Headache Disorders (ICHD-3), diagnostic criteria require at least two attacks fulfilling criteria for migraine with aura, with aura including fully reversible motor weakness, plus at least one other aura symptom (visual, sensory, or speech). **Clinical Diagnostic Criteria:** - At least two attacks fulfilling migraine with aura criteria - Aura includes fully reversible motor weakness - At least one other aura symptom present - At least two of: gradual onset, duration >60 minutes, aura symptoms are "positive," aura is followed by headache within 60 minutes ### Etymology & Word Origins **Hemiplegic:** - Greek "hemi-" meaning "half" - Greek "plege" meaning "stroke" or "paralysis" - Refers to paralysis of one side of the body **Migraine:** - Greek "hemikrania" meaning "half skull" - Originally described one-sided head pain ### Medical Terminology Matrix | Term Type | Content | Clinical Context | |-----------|---------|------------------| | **Primary Term** | Hemiplegic Migraine | Formal diagnosis | | **Subtypes** | Familial, Sporadic | Classification | | **Related Terms** | Motor Aura, Cortical Spreading Depression | Mechanism | ### Key Related Terms | Term | Definition | |------|------------| | **Aura** | Neurological symptoms preceding headache | | **Motor Aura** | Weakness as aura symptom | | **Familial Hemiplegic Migraine** | Inherited form | | **Sporadic Hemiplegic Migraine** | Non-inherited form | | **Cortical Spreading Depression** | Wave of brain activity changes | ---

Etymology & Origins

**Hemiplegic:** - Greek "hemi-" meaning "half" - Greek "plege" meaning "stroke" or "paralysis" - Refers to paralysis of one side of the body **Migraine:** - Greek "hemikrania" meaning "half skull" - Originally described one-sided head pain

Anatomy & Body Systems

Affected Body Systems

Central Nervous System: Brain, specifically motor cortex
Vascular System: Cerebral blood vessels
Trigeminal System: Pain pathways

Brain Regions Involved

Motor Cortex:

Primary motor cortex (Brodmann area 4)
Pre-motor cortex
Supplementary motor area
Control voluntary movement

Blood Vessels:

Cerebral arteries
Circle of Willis
Changes in blood flow during aura

Mechanism: Cortical Spreading Depression

Process:

Wave of abnormal electrical activity spreads across cortex
Initially increases blood flow
Then causes prolonged decrease in activity
This "depression" spreads at 2-3mm/minute
When it crosses motor cortex, weakness occurs
