Acephalgic Migraine
Acephalgic Migraine (pronounced: a-sef-al-gic my-grain), also known as a Silent Migraine, is a type of migraine that occurs without the characteristic headache. The term "Acephalgic" is derived from the Greek words "a" meaning without, and "kephale" meaning head, indicating a migraine without head pain.
Symptoms
The symptoms of an Acephalgic Migraine are similar to those of a typical migraine but without the headache. These may include aura, nausea, vomiting, photophobia (sensitivity to light), phonophobia (sensitivity to sound), and osmophobia (sensitivity to smell).
Causes
The exact cause of Acephalgic Migraine is unknown. However, it is believed to be related to changes in the brain, specifically in the cerebral cortex and underlying structures. Triggers can include stress, certain foods, changes in sleep patterns, and hormonal changes in women.
Diagnosis
Diagnosis of Acephalgic Migraine is often challenging due to the absence of headache. It is typically diagnosed based on the patient's symptoms and medical history. Diagnostic criteria include the presence of aura and other migraine symptoms without a headache.
Treatment
Treatment for Acephalgic Migraine is similar to that for other types of migraines. This may include medications to relieve symptoms, as well as lifestyle changes to avoid triggers. Medications may include triptans, ergotamines, and nonsteroidal anti-inflammatory drugs (NSAIDs).
