Time perception in migraine sufferers: an experimental matched-pairs study.

Area of Science:

• Neuroscience
• Psychology

Background:

• The influence of migraine on time perception remains under-investigated despite anecdotal reports.
• Systematic research is needed to understand temporal processing in migraineurs.

Purpose of the Study:

• To systematically investigate the impact of migraine on time perception.
• To compare temporal judgment abilities between migraineurs and healthy controls.
• To explore the role of subjective time awareness and depression in migraine-related temporal changes.

Main Methods:

• Experimental assessment of auditory duration estimation (ms and 1-s intervals) in 40 migraineurs and 40 matched controls.
• Utilized a time awareness questionnaire to evaluate subjective experience of time for longer durations.
• Subgroup analysis included assessment of depressive disorders.

Main Results:

• Migraineurs, as a whole group, did not significantly differ from controls in temporal judgments.
• No general over- or underestimation of temporal events was observed in migraineurs.
• A subgroup of migraineurs with comorbid depressive disorder exhibited accelerated internal timekeeping.

Conclusions:

• Migraine itself does not appear to broadly impair time perception.
• Comorbid depression significantly influences time perception in migraineurs, accelerating internal timekeeping.
• Depression is a critical covariable to consider when assessing time perception disturbances in migraine.
