磷脂絲氨酸:對多動症(注意力缺乏症)兒童有幫助 PS: Help for ADHD kids

對於注意力缺陷症(ADHD)兒童,服用磷脂絲氨酸(PS)或許會有幫助。一項最新研究表明,每天補充磷脂絲氨酸一段短時間便會有顯著改善。這項研究發布於人類營養和飲食期刊(Journal of Human Nutrition and Dietetics)。

磷脂絲氨酸普遍存在於高代謝活性器官(例如肺、心、腦和骨骼肌等),是維持腦功能最關鍵的營養素之一。在研究中,36名四歲至十四歲兒童每日服用200毫克磷脂絲氨酸,連續服用2個月。

研究人員得出的結論是,這能顯著改善ADHD症狀和短期聽力記憶。他們說:“補充磷脂絲氨酸可能是其中一種最為天然和安全的方法,改善患有ADHD年幼童的心理表現。”

“缺乏磷脂與神經元結構和功能損傷有莫大關係,在兒童早期發育過程中這關係尤為明顯。”首席研究員T. Hirayama表示。“飲食中缺乏必需脂肪酸和磷脂可能會增加童年患上注意力缺乏症的風險....通過補充磷脂絲氨酸能有效糾正這種根本性失衡,這可能是一個重要的治療策略。”這項研究也確認了早前的另一項研究結果。

PS: Help for ADHD kids

Kids with attention-deficit hyperactivity disorder (ADHD) may benefit from taking phosphatidylserine (PS). A new study suggests that daily doses of the supplement creates significant improvement, even over a short period of time. The study can be found in the Journal of Human Nutrition and Dietetics.

Phosphatidylserine is a nutrient found in organs with high metabolic activity, like lungs, heart, brains and skeletal muscle. It's one of the nutrients most critical to brain function. In the study, 36 children between the ages of four and 14 were given PS in supplement form at a dose of 200 mg per day per two months.

The researchers concluded that the supplement significantly improved ADHD symptoms and short-term auditory memory in children. They wrote that “PS supplementation might be a safe and natural nutritional strategy for improving mental performance in young children suffering from ADHD.”

“Phospholipid deficiencies are linked to impairments in neuronal structure and function, especially during early development,” wrote lead researcher, T. Hirayama. “Dietary deficiency in essential fatty acids and phospholipids during childhood may increase the risk of developing ADHD-type symptoms....correcting underlying imbalances through PS supplementation may be an important treatment strategy in cases where deficiency exists." The research confirms results from an earlier pilot study.
