The pathologic features of adult-onset leukoencephalopathy/leukodystrophy with axonal spheroids (ALAS) are variable, and this has led to different hypotheses as to whether primarily demyelination or axonopathy may underlie this disorder. Typical ALAS pathology is rarely accompanied by focal multiple sclerosis
