摘要

G6PD deficiency is an important risk factor of death and kernicterus (1). Here we discuss another possible clinical and research implication for G6PD deficiency. Impaired balance of oxidant-antioxidant status (2) and increased oxidative stress is reported in attention deficit/ hyperactivity disorder (3). There is a high level of oxidant nitric oxide and low level of antioxidant superoxide dismu-tase in adult ADHD (4). In addition, there is evidence that acute use of methylphenidate increases superoxide level in young rats, whereas chronic use of methylphenidate, which is used widely for management of ADHD, decreases the production of superoxide in cerebellum in adult rats (5). Moreover, nitrogen dioxide produced by cooking gas increases the risk of developing ADHD symptoms in later years (6). Nitrogen dioxide impairs dopamine biosynthesis, which can lead to the development of ADHD symptoms (7). Glutathione (GSH) plays a major role in antioxidant defenses against oxidative stress (7). Impaired GSH regeneration enhances oxidative damage (8).
