Unilateral or asymmetric localization of lambda waves is not a pathologic finding.
This article reports on three children who underwent an electroencephalographic examination. All three showed the feature of asymmetric lambda waves, which is usually interpreted as a pathologic focal phenomenon. The report documents that asymmetric lambda waves and photic driving might be normal variants, not requiring further investigation.
