Abstract: | Clinical observations
show that migraine attacks have a
seasonal, menstrual and circadian
timing, suggesting a role of chronobiological
mechanisms and their
alterations in the disease, but little
experimental data exists about this
issue. The aim of this study was to
estimate sleep quality chronotypes
and the possible circadian timing of
attacks in migraneurs. One hundred
patients suffering from migraine
without aura according to the IHS
criteria (2004), and 30 controls were
enrolled. Morning and evening type
subjects were more represented in
migraine patients than in controls
and showed a tendency towards
worse sleep quality and higher disability.
Forty–two percent of
migraineurs presented more than
75% of their attacks at night.
Morning and evening types rather
than intermediate and differences
between real and preferred times
may represent stressors that can
worsen the disease. A preferential
timing for occurrence of migraine
attacks during the night and early
morning hours was documented. |
