Medication-overuse headache detoxification reduces headache disability - the Akershus study of chronic headache.

Medication-overuse headache causes substantial disability in the general population. Self-detoxification leads to reduced headache frequency and disability, although 24% of the participants did not complete self-detoxification. Detoxification should be offered to MOH patients as early as possible with a focus on headache frequency, disability and psychological distress.
