IHS	Diagnosis	ICD-10
1.5.3	Persistent aura without infarction	G43.3

Description:

Aura symptoms persist for more than 1 week without radiographic evidence of infarction.

Diagnostic criteria:

The present attack in a patient with 1.2 Migraine with aura is typical of previous attacks except that one or more aura symptoms persists for >1 week
Not attributed to another disorder

Comment:

Persisting aura symptoms are rare but well documented. They are often bilateral and may last for months or years. Reliably effective treatment is not known though acetazolamide and valproic acid have helped in a few cases.

Exclude posterior leukoencephalopathy by diffusion MRI among other things. Exclude 1.5.4 Migrainous infarction by MRI.
