Migraines and mental decline
August 10, 2012
A NEW study is calling into
question the link between migraine
and cognitive decline, with
researchers revealing their findings
showed that migraine status does
not correlate with faster rates of
cognitive decline.
The research, published in the
British Medical Journal, looked at
6,349 women aged 65 or older
who were assessed for their
migraine status at the start of the
study, and then grouped into four
groups: no history of migraine,
migraine with aura, migraine
without aura, and past history of
migraine (reports of migraine
history but no migraine in the year
prior to baseline).
The researchers then followed
the women up with cognitive
testing at two year intervals up to
three times.
Interestingly the researchers
found that the women who
experienced migraines with or
without auras, or who had a past
history of migraines did not have
significantly different rates of
cognitive decline in any of the
cognitive scores.
In addition, the researchers
found that participants who
experienced migraines were also
not at increased risk of substantial
cognitive decline.
The results sit in contrast to past
studies which associated migraines
with an increased prevalence of
clinically silently brain lesionswhich
are a risk factor for
dementia and cognitive decline.
