Brain imaging in migraine with and without aura: Similarities and differences
View abstract on PubMed
Summary
This summary is machine-generated.Migraine with aura (MA) shows distinct visual processing, cerebellar, and thalamic differences compared to migraine without aura (MO). However, neuroimaging studies reveal inconsistencies, necessitating standardized research for clearer distinctions.
Area Of Science
- Neurology
- Neuroimaging
- Pathophysiology
Background
- The biological independence of migraine with aura (MA) from migraine without aura (MO) remains debated.
- Neuroimaging studies offer insights into the pathophysiology of both migraine types.
- Understanding functional and structural differences is crucial.
Purpose Of The Study
- To review neuroimaging studies comparing migraine with aura and migraine without aura.
- To elucidate functional and structural differences between MA and MO.
Main Methods
- A comprehensive PubMed search of neuroimaging studies comparing MA and MO was conducted.
- Included studies utilized diffusion tensor imaging, voxel-based morphometry, surface-based morphometry, functional MRI, and arterial spin labeling.
- No publication date restrictions were applied.
Main Results
- MA patients showed heightened engagement in visual regions, cerebellum, and thalamus.
- Both MA and MO involved parts of the salience network and similar visual areas.
- Inconsistencies were noted due to study design, patient inclusion, and analysis methods.
Conclusions
- MA patients exhibited greater visual region involvement, reduced cerebellar antinociceptive activity, and impaired thalamic filtering.
- Biases in current studies limit the reliability of findings.
- Further standardized research is required to definitively differentiate MA and MO.

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...
Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
