Migraine Aura Without Headache - The Medical consequences

Migraine Without Headache
It is also known as migraine aura without headache or Silent Migraines. Migraine aura without headache should be considered as a diagnosis in anyone who has recurrent episodes of transient symptoms, especially those that are visual or neurological or involve vertigo. Visual and neurological symptoms due to migraine are not unusual and most commonly occur in older persons with a history of migraine headaches. Migraine aura without headache should be diagnosed only when transient. Migraine auras are reversible and recurrent episodes of neurological symptoms that resolve within 1 hour. They are associated with migraine but may not precede a headache, according to "Migraine aura without headache:
Benign, but a diagnosis of exclusion" by ROBERT S. KUNKEL, MD Consultant, Headache Center, Department of Neurology, The Cleveland Clinic Foundation (Page 529)(a).
