Chronic Daily Headache Looks like...
NDPH is a type of Chronic Daily Headache (CDH), not a new name for it.
CDH refers to any headache that happens at least 15 days each month for more than three months, and NDPH is just one of its subtypes.
NDPH is a headache that begins suddenly and happens every day from the start. It is often there all the time, lasting at least three months, and for many people, it can go on for years.
NDPH is rare, affecting less than 1% of people, and seems to be more common in women than in men. Experts still do not fully understand what causes it, which may be why the difference between men and women is not yet explained.
