Brain plasticity and migraine transformation: fMRI evidences

Area of Science:

• Neuroscience
• Medical Imaging

Background:

• Episodic migraine can transform into chronic migraine through progressive biological changes in the brain.
• These changes affect neuronal function, synaptic activity, neurotransmitter systems, receptor expression, brain connectivity, and pain modulation pathways.
• Genetic predisposition plays a role in individuals susceptible to migraine chronification.

Purpose of the Study:

• To summarize the pathophysiology of migraine chronification and associated brain plasticity.
• To describe functional magnetic resonance imaging (fMRI) techniques used in migraine research.
• To present current fMRI evidence on brain transformation during migraine chronification.

Main Methods:

• Literature review of recent PubMed publications on migraine chronification and fMRI.
• Synthesis of data on the biological mechanisms underlying migraine progression.
• Analysis of fMRI studies investigating brain alterations in chronic migraine.

Main Results:

• fMRI has provided insights into the unique characteristics of the migrainous brain and its propensity for chronicity.
• Evidence suggests widespread modifications in brain structure and function contribute to the transition from episodic to chronic migraine.
• Specific fMRI findings highlight altered neural activity and connectivity in pain-processing networks.

Conclusions:

• Migraine chronification is a complex process involving progressive neurobiological alterations.
• fMRI is a valuable tool for understanding the migrainous brain's transformation but cannot yet fully explain the underlying mechanisms.
• Further research is needed to identify predisposing factors and differentiate cause-and-effect relationships in migraine chronification.
