G43.701
Chronic migraine without aura, not intractable, with status migrainosus
Clinical Classification Guidelines
Medical Intelligence & Overview
Chronic migraine without aura with status migrainosus is a type of persistent migraine characterized by frequent and severe headache episodes. Unlike occasional migraines, this condition involves daily or near-daily headaches that significantly impact daily life. The 'without aura' designation indicates the absence of sensory disturbances like visual flashes or tingling sensations that sometimes precede migraines. The addition of 'status migrainosus' refers to prolonged, intense migraine episodes lasting longer than 72 hours, often with little relief even after medication. This condition is not typically labeled as intractable, meaning it may respond to standard treatments, but its persistent nature can pose ongoing challenges for those affected.

Diagnostic & Treatment
Diagnosis Path: Diagnosis is primarily clinical, based on the patient's history and reported symptoms. Healthcare providers will ruling out other causes through neurological examinations and may order imaging tests, such as MRI or CT scans, to exclude other conditions. The diagnostic criteria include frequent headaches, characteristics of migraines without aura, and the presence of a status migrainosus episode. Keeping a headache diary can help in documenting the pattern and severity of migraines, aiding in accurate diagnosis.
Treatment Protocols: Treatment strategies aim to reduce the frequency, severity, and duration of migraines, especially during status migrainosus episodes. Approaches include:
