brain lesions
Abnormal neural tissue
Brain lesions are areas of damaged or abnormal tissue in the brain.
The term covers a wide range of conditions—tumors, strokes, infections, injuries, or the plaques characteristic of multiple sclerosis.
Lesions may cause symptoms depending on their location and size, or remain silent until discovered on imaging: The MRI revealed several brain lesions.
- strokeSudden brain blood blockage
- MRIMagnetic body imaging
- demyelinationNerve sheath degradation
- infarctDead tissue from blocked artery
- seizuresInvoluntary convulsions or takings
