CIS in children are optic neuritis (ON), transverse myelitis (TM), or brainstem/cerebellar syndromes or syndromes attributed to the cerebral hemi-spheres.3,5 Unilateral ON is defined by acute/sub-acute and painful visual loss, impairment of visual acuity and color perception, MRI evidence of optic nerve swelling, or abnormal signal or enhancement.3

Abnormalities in electroencephalograph (EEC) theta and delta activity, visual evoked potentials, and brainstem evoked poten-tials have been reported in children exposed to molds.27 The EEC changes in the children were specific to the frontotemporal area of the brain, suggesting a metabol-ic encephalopathy.
