Hemicrania continua: remitting stage evolved from the chronic form

Area of Science:

• Neurology
• Headache Medicine

Background:

• Hemicrania continua is a primary headache disorder.
• It is typically characterized by a continuous, unilateral headache.
• A remitting stage may precede the chronic stage in some cases.

Observation:

• This study reports the reverse temporal sequence in hemicrania continua.
• The headache initially presented in a chronic pattern.
• Indomethacin treatment initiated a transition to a remitting pattern upon withdrawal and re-initiation.

Findings:

• A patient demonstrated a shift from chronic to remitting hemicrania continua.
• Indomethacin provided sustained relief, with symptom patterns changing upon drug withdrawal and resumption.
• This observation supports the existence of dual temporal patterns in hemicrania continua.

Implications:

• The findings suggest a more complex temporal presentation of hemicrania continua than previously understood.
• This highlights the importance of considering evolving headache patterns in diagnosis and management.
• Indomethacin's efficacy in both chronic and remitting phases underscores its therapeutic role.
