Quick Answer
Migraine aura involves temporary visual, sensory or speech symptoms that typically develop over 5-60 minutes before headache onset.

Migraine aura is a phase of the migraine attack that occurs before or during headache, involving temporary neurological symptoms that develop gradually over 5 to 60 minutes. Approximately 25-30% of people with migraine experience aura, though not every attack includes it.
Common aura symptoms: Visual aura is the most frequent, occurring in about 90% of aura episodes. Typical symptoms include zigzag lines (fortification spectra), flashing lights, blind spots (scotomata), or sparkling dots that spread across the visual field over several minutes. The symptoms are positive (something added to vision) rather than simply dark or blank, and they spread progressively rather than appearing all at once.
Dr. Jitendra Prasad Yadav — consultant neurologist & headache specialist at Kathmandu Neurology Clinic & Cognitive Center provides evidence-based evaluation for migraine.
Sensory aura causes tingling or numbness that begins in one area —— often the fingers or around the mouth —— and spreads slowly upward over 5-20 minutes along one side of the body. Speech aura involves difficulty finding words, producing slurred speech, or trouble understanding language. Motor weakness (hemiplegic migraine) is less common but well-recognized.
Aura without headache: Some individuals experience aura followed by no headache at all, or with only mild headache. This is recognized in ICHD-3 as migraine with aura without headache. It is important to distinguish this from transient ischaemic attack (TIA), which can produce similar symptoms. The key difference is pattern: migraine aura develops gradually over minutes, spreads progressively, and resolves completely, whereas TIA typically presents as a sudden fixed deficit that resolves without the characteristic gradual spread.
When aura warrants investigation: New-onset aura after age 50, aura that differs from previous episodes (different symptoms, different progression, longer duration), aura without personal or family history of migraine, or aura with persistent neurological deficit after resolution should prompt medical evaluation including brain MRI to exclude vascular or structural causes.
Differential diagnosis: Aura symptoms can mimic stroke, TIA, seizure (particularly focal seizures with secondary generalization), and transient global amnesia. The gradual onset, progressive spread, and complete resolution distinguish migraine aura from stroke, which typically has sudden onset of a fixed deficit. EEG may be considered when seizure is in the differential.
At Kathmandu Neurology Clinic & Cognitive Center, Dr. Jitendra Prasad Yadav (NMC 8029) evaluates aura symptoms using ICHD-3 criteria, distinguishes migraine aura from vascular mimics, and orders MRI and EEG selectively when clinical features are atypical.

Migraine is a neurological condition; headache is one feature. Associated symptoms and functional impact are important for diagnosis.
Aura refers to visual, sensory, or speech symptoms that precede the headache in some people. Both types are migraine; the presence of aura may influence management discussion.
Cervical sensations can coexist, but dizziness is often multifactorial and needs systematic assessment rather than assuming a single neck cause.
Yes; vertigo is the sensation of spinning. Dizziness is a broader term including lightheadedness, unsteadiness, and near-fainting. Different causes underlie each.
Prevention is discussed after 4–8 weeks of diary shows ≥8 migrainous days/month or medication-overuse pattern. Options include lifestyle regularity, comorbidity treatment and preventive medicines selected per history and contraindications. No preventive works instantly; follow-up with the same consultant tracks days/mo…
Yes. Short or fragmented sleep impairs memory consolidation and lowers migraine threshold. Snoring with apneas fragments sleep and fragments cognition. Dr. Jitendra screens sleep duration, regularity, snoring and caffeine, and refers for sleep study when indicated — often before escalating headache or memory medicines.
