ICD-10: G43.50

Persistent migraine aura without cerebral infarction, classified under ICD-10 code G43.50, is a specific diagnosis that pertains to a type of migraine characterized by prolonged aura symptoms. Below is a detailed clinical description and relevant information regarding this condition.

Clinical Description

Definition

Persistent migraine aura without cerebral infarction refers to a condition where patients experience migraine aura symptoms that last longer than the typical duration but do not result in any cerebral infarction (i.e., no permanent brain damage). The aura can manifest as visual disturbances, sensory changes, or other neurological symptoms that precede or accompany a migraine headache.

Symptoms

The symptoms of persistent migraine aura can include:
- Visual Disturbances: These may involve flickering lights, zigzag patterns, or temporary loss of vision.
- Sensory Changes: Patients might experience tingling or numbness, often in the face or extremities.
- Speech or Language Disturbances: Some individuals may have difficulty speaking or understanding language during an aura episode.
- Duration: Unlike typical migraine auras that last from a few minutes to an hour, persistent migraine aura can last for days, although it is not classified as intractable.

Diagnosis Criteria

To diagnose persistent migraine aura without cerebral infarction, clinicians typically consider:
- The presence of aura symptoms that last longer than one hour but less than seven days.
- The absence of evidence indicating cerebral infarction, which can be assessed through imaging studies such as MRI or CT scans.
- A history of migraine attacks, as this condition is often seen in patients with a prior diagnosis of migraine.
