| IHS | Diagnosis | ICD-10 |
|---|---|---|
| 1.2.2 | Typical aura with non-migraine headache | G43.10 |
Description:
Typical aura consisting of visual and/or sensory and/or speech symptoms. Gradual development, duration no longer than one hour, a mix of positive and negative features and complete reversibility characterise the aura which is associated with a headache that does not fulfil criteria for 1.1 Migraine without aura.
Diagnostic criteria:
- At least 2 attacks fulfilling criteria B-D
- Aura consisting of at least one of the following, but no motor weakness:
- fully reversible visual symptoms including positive features (eg, flickering lights, spots or lines) and/or negative features (ie, loss of vision)
- fully reversible sensory symptoms including positive features (ie, pins and needles) and/or negative features (ie, numbness)
- fully reversible dysphasic speech disturbance
- At least two of the following:
- homonymous visual symptoms1 and/or unilateral sensory symptoms
- at least one aura symptom develops gradually over ≥5 minutes and/or different aura symptoms occur in succession over ≥5 minutes
- each symptom lasts ≥5 and ≤60 minutes
- Headache that does not fulfil criteria B-D for 1.1 Migraine without aura begins during the aura or follows aura within 60 minutes
- Not attributed to another disorder2
Notes:
- Additional loss or blurring of central vision may occur.
- History and physical and neurological examinations do not suggest any of the disorders listed in groups 5-12, or history and/or physical and/or neurological examinations do suggest such disorder but it is ruled out by appropriate investigations, or such disorder is present but attacks do not occur for the first time in close temporal relation to the disorder.
Comment:
In the absence of headache fulfilling criteria for 1.1 Migraine without aura, precise diagnosis of aura and its distinction from mimics that may signal serious disease (eg, transient ischaemic attack) become much more important.
