Silent migraines, also known as acephalgic migraines, are a type of migraine headache that do not include a headache as part of the symptom. Instead, sufferers may experience auras, such as blurred vision, sensory changes, and dizziness. Silent migraines differ from other types of headaches in that they rarely include the traditional headache pain and throbbing associated with other migraine headaches. The cause of silent migraines is the same as with other migraine types, which is believed to be related to changes in the brain's blood vessels. Treatment for silent migraine may include lifestyle changes, such as avoiding triggers, and medications. Silent migraines can be difficult to diagnose as the lack of a headache can make it hard for a person to recognize that they are having a migraine. Additionally, because the symptoms can vary from person to person, it can be difficult for a doctor to determine if a person is actually having a silent migraine or another type of headache. It is important to talk to a doctor if a person is experiencing any of the symptoms associated with silent migraines, so that they can receive an accurate diagnosis and the appropriate treatment.
