Evolutionary game model of migraine based on the human brain hypersensitivity

Area of Science:

• Evolutionary biology
• Neuroscience
• Genetics

Background:

• Migraine affects approximately 14% of the global population, presenting a significant public health challenge.
• Despite its disabling nature, migraine's persistence suggests underlying evolutionary advantages.
• Genes associated with migraine often lead to hypersensitivity in sensory organs and the cerebral cortex.

Purpose of the Study:

• To explore the evolutionary mechanics of migraine through a game theory model.
• To investigate the role of human brain hypersensitivity as a prerequisite for migraine's evolutionary advantage.
• To provide a potential evolutionary explanation for the continued prevalence of migraine.

Main Methods:

• Utilized game theory principles, drawing parallels with the Hawk-Dove game.
• Developed an evolutionary game model comparing migraineurs (hypersensitive) and non-migraineurs (less sensitive).
• Analyzed fitness values associated with different phenotypes in an evolutionary context.

Main Results:

• Proposed a model where migraineurs' hypersensitivity aids in early threat detection.
• Suggested a cooperative dynamic where migraineurs warn non-migraineurs of danger, with mutual benefit for survival.
• Highlighted hypersensitivity as a key factor enabling this evolutionary game.

Conclusions:

• Migraine's persistence may be linked to an evolutionary advantage derived from enhanced sensory processing.
• The hypersensitivity associated with migraine could facilitate survival through improved threat recognition.
• Game theory provides a framework for understanding the evolutionary dynamics of migraine.
