Memory loss is a
common complaint in headache sufferers. In a 2004 study, which was
published in The Journal of Headache and Pain, 71 patients, 50 women
and 21 men, affected by chronic daily headache with different
diagnoses at onset and at study entry, underwent a test battery in
order to evaluate both short- and long-term memory. A percentage of
patients, ranging from 2% to 56%, according to the different tests,
showed a worse performance than normal subjects. The percentage of
the subjects with memory difficulty was higher in women and in
patients with migraine-type headache at onset. Researchers concluded
that a complex neurotransmitter disorder might account for impairment
of both short-term and long-term memory in headache patients.
