At least half of patients with X-ALD are adults with somewhat milder manifestations, and women who are carriers may become symptomatic. X-ALD is often misdiagnosed as attention-deficit/hyperactivity disorder in boys and as multiple sclerosis in men and women, and is not an uncommon cause of Addison disease;(2) the incidence of X-ALD, estimated to be 1:17 000 in all ethnic groups, approximates that of phenylketonuria;(3) noninvasive and presymptomatic diagnosis and prenatal diagnosis are available; family screening and genetic counseling are key to disease prevention; and (4) new therapies, applied early, show promise.

至少1半的X-ALD为成年病人，表现较轻，而作为携带者的女性也可发病。X-ALD在男孩常误诊为注意缺陷/多动综合征，男女可误诊为多发性硬化，并且也是Addison病的病因；(2)据估计X-ALD发病率为1：17 000，类似于苯丙酮尿症；(3)可进行无创性、症状前诊断和产前诊断；家系筛查和遗传咨询是疾病预防的关键；(4)早期采用新的治疗方法非常具有前景。
