Prolonged Aura Migraine, also known as persistent aura without infarction, is a neurological condition characterized by recurring episodes of prolonged visual disturbances, typically lasting longer than one hour. This condition is a subtype of migraine with aura, which is a type of headache disorder that involves visual, sensory, or motor disturbances preceding or accompanying the headache phase.
The prolonged aura experienced by individuals with this condition includes a wide range of visual symptoms, such as flickering lights, blind spots, zigzag lines, or shimmering lights. These visual disturbances tend to gradually spread across the field of vision, affecting both eyes. In some cases, other sensory symptoms like tingling or numbness in the face, arms, or legs may also occur.
Unlike typical migraines, where the aura symptoms last for a short period of time (usually less than one hour), prolonged aura migraines can persist for several hours, days, or even weeks. This chronic nature of the condition often leads to significant impairment in the affected individual's quality of life. However, it is important to note that prolonged aura migraines are not associated with an increased risk of stroke or other serious complications.
Treatment for prolonged aura migraines usually involves the use of medications to manage the symptoms and reduce the frequency and intensity of the episodes. Medications commonly prescribed include certain types of anti-epileptic drugs, antidepressants, and calcium channel blockers. Lifestyle modifications, such as stress reduction techniques, regular exercise, and adequate sleep, may also be recommended to manage the condition effectively.
