CHRONIC PAROXYSMAL HEMICRANIA (CPH) AND HEMICRANIA CONTINUA - TRANSITION FROM ONE-STAGE TO ANOTHER

Two female patients, one suffering from CPH in non-remitting form, and the other from hemicrania continua, in the pre-chronic (non-continuou s) stage are described. Both were followed through transitions to othe r stages: the CPH patient was followed from the non-remitting stage to a longlasting remission, and lastly back to another chronic stage. In domethacin was effective in all the symptomatic stages. The hemicrania continua patient was followed from the non-continuous to the continuo us stage. Indomethacin was effective in both stages. These observation s provide further evidence that the non-chronic and chronic (''remitti ng'' and ''non-remitting'') stages of CPH belong together. The same se ems to apply to the two stages of hemicrania continua, the ''continuou s'' and the ''non-continuous'' stages.
