保持年輕和腦筋靈活有辦法 Think Young and Stay Sharp 列印
作者是 4S Pharmacists   

人類的大腦包含一千億個神經細胞,每個細胞與其他許多細胞互相溝通,讓我們有聽力、學習能力、記憶力、視力、臭覺和思考能力。 大腦細胞就像微形工廠,負責供應鏈、生產、設備建立保養和廢物處理等多項工序。 患有老人癡呆症(阿爾茨海默氏病,AD)病人某些腦細胞發生故障,以至腦功能受到影響。當這些故障惡化蔓延,腦細胞變得未能執行應有的任務,嚴重者最終更導致腦細胞死亡。
根據2001年人口普查,香港大約有75萬六十五上以上長者,當中大概百分之十(七萬五千人)患有老人癡呆症。儘管目前沒有徹底治療這症的方法,我們也應該主動采取措施,防止或延緩記憶力衰退。

如果你不使用它,你就會失去它
運動鍛煉有助提升身體供氧能力,令神經遞質(腦細胞之間的化學信使)產量增加,並減少對這些細胞的損害。最近一項有關老年人記憶力的隨機臨床實驗顯示,有記憶問題(但未患上癡呆症)的老年人透過運動鍛煉,認知能力大為提高,而那些沒定期運動的人士的認知能力則有各種程度的下降。同樣地,透過不斷考驗腦細胞的工作能力能有效減少一半老年癡呆症的發病率。任何年齡人士透過報讀或教授課程,例如學一門新的語言,都能刺激平常少用的思維能力,增加腦細胞數量。 同樣地,玩電腦遊戲、學習新軟件或電腦操作系統、演奏樂器、做填字遊戲或數獨、閱讀、舞蹈課程等均能刺激大腦使運作更暢順。在家或工作上遇上難題,那種“反芻”或重複思考似乎也有助降低患病風險。

其他因素

瑞典的研究發現,人到中年,活躍的社交活動有助防止或延緩認知能力衰退。斯德哥爾摩Karolinska研究所研究員克裏斯特哈坎森認為 “夫妻相處也是其中一種社交關係和智力刺激活動。”克裏斯特並指出,活躍的社交生活和群體活動也非常重要。"根據法國一項研究,患有抑鬱症婦女和曾經中風的男性患上老人癡呆症的比例較高,這表明患上 AD的風險可能有性別區分。最近一項研究則指出,男士為了對抗前列腺癌而接受荷爾蒙抑制療程似乎也會影響記憶和使精神不能集中。某種早發性AD(一種罕見的老年癡呆症類型)則可能與遺傳基因有關。此外,患有唐氏綜合症(遺傳性)也可能更易患上此症。

整體健康狀況對保持思想敏銳發揮了重要作用。代謝綜合症(特點是腹部肥胖)、高密度膽固醇(健康膽固醇)偏低、膽固醇和血壓偏高、血糖和甘油三酯偏高等除了增加二型糖尿病、高血壓和中風的風險外,也會增加患上此症的幾會率。

除了血壓、BMI指數和膽固醇水平或教育程度等因素,50歲以上胰島素分泌過低的男性比沒有胰島素失調的男性患上此症的機會也增加一倍半。瑞典烏普薩拉大學埃利娜倫內馬博士解釋:“可能是胰島素問題損害了大腦血管,導致記憶力衰退和老人癡呆症。”另外,動脈硬化、血壓非常高和頭部受傷等都與老人癡呆症有聯系。

除了以上種種,經常接觸重金屬而又缺少某些微量元素的人士,患上老人癡呆症的風險也會偏高。鋁和汞(水銀)是其中的元兇。最近研究發現,經常飲用每公升含鋁超過100微克的清水是導致老人癡呆症的其中一個因素。但目前為止各地並沒有正式立例限制飲用水的鋁含量。

均衡飲食與營養補充

天然健康的飲食習慣除有助預防心臟病和II型糖尿病外,對預防AD也有幫助。飲食習慣方面應盡量選擇顏色鮮豔的水果和蔬菜,避免油炸和垃圾食品、腌制或煙熏肉類和含反式脂肪食物。

FRSH研究員艾倫C洛根博士認為:“腦部百分之六十為脂肪,而大量研究確定了奧米加3脂肪酸對大腦的好處。”因此他推薦食用深海魚及魚油補充劑。動物實驗中,魚類所含的DHA不僅有助於預防腦細胞損傷,也有延緩AD的作用。

許多研究發現,銀杏葉有助提高警覺性,同時能改善記憶和情緒,並能增加紅血球中奧米加3水平。洛根博士認為: “銀杏可能是最有效預防老人癡呆癥的一種植物。”

最近一項研究,詹姆斯博士提到:“薑黃提取物(薑黃素)和大蒜、生薑等所含的多種天然成分,有助阻截β-澱粉樣蛋白形成,而β-澱粉樣蛋白正是導致腦血管斑塊和阻礙腦功能以至形成老人癡呆症的罪魁禍首。而在印度,人們經常服用三種印度草藥,而根據流行病學研究顯示,當地患有老人癡呆症的病例明顯低於西方人種。

乙酰左旋肉鹼有助減緩記憶力衰退和減少自由基產生對腦細胞造成的損害。維他命E類抗氧化劑也有助延緩中度老人癡呆症病情惡化。最近一項研究表明,增加維他命E攝取量能提高老人癡呆症患者存活率。而加拿大的一項研究表明,維他命C和E能有助改善患II型糖尿病長者的記憶力。

腦掃描研究表明,每日補充鉻(chromium picolinate)能加強有早期老年性記憶衰退和代謝失調問題人士的大腦活動。硼(Boron)是另一種能提高大腦功能和記憶力的“智能”礦物質。缺乏鋅(Zinc)與AD的澱粉樣斑塊形成有關,因此每日服用含鋅的多種維他命礦物質配方有助預防此症。

膽鹼(Choline)是維他命B族的其中一員,主要存在於卵磷脂。根據抗衰老專家羅納德克拉茨博士和和羅伯特高盛博士表示“多個歐洲國家都訂明膽鹼有治療認知功能障礙的作用。”當與其他維他命B類(包括葉酸、維他命B6、B12等)同服,膽鹼有助降低同型半胱氨酸水平,而這種物質偏高與老人癡呆症和和心血管疾病有密切關系。

芝加哥拉什老年健康研究所的一項目研究認為,體內菸酸(維他命B3)偏低的人士相對於正常人士患上AD的比例高出百分之七十,因此,經常服用維他命B雜相當有用。

艾倫約瑟夫博士認為:“磷脂絲氨酸(PS)來自卵磷脂,屬於一種特殊的脂溶性物質,它是組成腦細胞膜必不可少的成分。”他說:“磷脂絲氨酸對AD有改善腦部功能的作用,例如能夠記住自己的名字和找回以前放東西的位置等。”磷脂絲氨酸是少數幾種對後期老年癡呆癥患者有用的營養補充劑。

The human brain contains 100 billion nerve cells, each communicating with many others so that we canhear, learn, remember, see, smell, and think. Like tiny factories,brain cells take in supplies, generate energy, build needed equipment,and dispose of wastes. In Alzheimer’s disease (AD), however, parts ofthese cellular factories begin experiencing backups or breakdowns. Asdamage spreads, brain cells fail to perform needed tasks, andeventually, they may die.

A progressive brain disease, ADafflicts as many as seventy thousand Hong Kong people. Others may suffer fromreduced blood flow to parts of the brain, known as vascular dementia.While these conditions currently have no cure, we can all take steps toprevent or slow memory loss.

Use It or Lose It
Physicalactivity helps oxygenate your body, increases the production ofneurotransmitters (chemical messenger between brain cells), and reducesdamage to these cells. A recent randomized trial of older adults whoreported memory problems (but did not suffer from dementia) finds thatthose who exercised improved their cognitive skills, while those whodidn’t showed cognitive losses.

Similarly, putting our braincells through their paces can cut the incidence of Alzheimer’s in half.At any age, take or teach a class. Learning a new language, forexample, stimulates you to think in a way you don’t ordinarily,increasing your reserve of brain cells. Similarly, playing computergames, tackling new software or a computer operating system, learningto play a musical instrument, doing crossword puzzles or Sudoku,reading, and taking dance lessons all stimulate the brain in meaningfulways. Rumination, or the tendency toward repetitive thinking whenconfronted with problems at home or at work, also appears to lower therisk for AD.

Other Factors

Swedish research finds that socialinteraction at midlife helps protect against cognitive impairmentlater. “Living in a couple[s] relationship is normally one of the mostintense forms of social and intellectual stimulation,” says researcherKrister Hakansson at the Karolinska Institute in Stockholm. But anactive social life and group activities appear useful, as well.

Depressionin women and stroke in men are risk factors, according to Frenchresearch, indicating that AD risk factors may sometimes begender-specific. Men undergoing hormone deprivation to keep prostatecancer in check also appear to suffer memory loss and have troubleconcentrating, a recent study in the journal Cancer reports. Genes area factor in one type of early-onset AD, a rare form of Alzheimer’s.Also, people with Down syndrome (genetically based) may be more likelyto develop AD.

Health status plays an important role in stayingmentally sharp. Metabolic syndrome, characterized by abdominal obesity;low HDL (healthy) cholesterol; and elevated blood pressure, bloodsugar, and triglycerides, raises the risk of AD as well as Type 2diabetes, hypertension, and stroke. Regardless of blood pressure,body-mass index, cholesterol levels, or education, 50 year-old men withlow insulin are nearly one-and-a-half times as likely to suffer from ADas those without insulin disorders. “It’s possible that insulinproblems damage blood vessels in the brain, which leads to memoryproblems and Alzheimer’s disease,” says Elina Ronnemaa, MD, at Sweden’sUppsala University. Arteriosclerosis, very high blood pressure, andhead injury have also been linked to AD.

Finally, exposure toheavy metals, particularly when combined with a lack of micronutrients,may also predispose a person to Alzheimer’s. Aluminum and mercury areprime culprits. Recent research suggests that aluminum above 100micrograms per liter in drinking water may be a risk factor for AD anddementia. But no official limit currently exists.

Smart Diet & Supplements

Ahealthy, whole-foods diet that fights heart disease and Type 2 diabeteshelps protect against AD. Enjoy plenty of brightly colored fruits andvegetables, and avoid fried and junk foods, cured and smoked meats, andtrans fats.
“Given that the brain is 60 percent fat and given thewealth of research on the value of omega-3 fatty acids in the brain(and beyond),” Alan C. Logan, ND, FRSH, recommends deep-water fish andfish oil supplements. Not only does DHA in fish help prevent brain celldamage in animal studies, but it also appears to slow mental damage inAlzheimer’s.

Found in numerous studies to increase alertnesswhile improving memory and mood, ginkgo (G. biloba) appears to boostomega-3 levels in red blood cells. “Ginkgo is probably most effectiveas a preventative plant,” says Dr. Logan.

“Extractsof turmeric (Curcuma longa L.), like those of garlic (Allium sativum)and ginger (Zingiber officinale), contain a number of natural agentsthat block the formation of beta-amyloid, the substance responsible forthe plaques that slowly obstruct cerebral function in Alzheimer’sdisease,” writes James A. Duke, PhD, in a recent study. “In India,where these three Ayurvedic herbs are a regular part of the diet, theepidemiologic magnitude of Alzheimer’s disease in notably lower than itis in the West,” he adds.

Acetyl-L-carnitine slows memory loss and reduces theproduction of free radicals which are damaging to brain cells.Antioxidant vitamin E has also been shown to delay the progression ofmoderate AD, and a recent study suggests that increased intake of thisvitamin improves the survival rate of Alzheimer’s patients. AndCanadian research suggests that vitamins C and E help improve memory inolder people with Type 2 diabetes.

Brain imaging investigationssuggest that daily supplementation with chromium picolinate increasebrain activity in older adults experiencing early memory loss andmetabolic irregularities that raise the risk of dementia. Boron, whichimproves brain function and memory, is another “smart” mineral. Zincdeficiency has been linked to the formation of amyloid plaque inAlzheimer’s, so look for this mineral in your dailymultivitamin-mineral formula.

Choline, a B vitamin found inlecithin, “is frequently prescribed for the treatment of cognitiveimpairment in several Europeans countries,” according to antiagingexperts Ronald Klatz, MD, DO, and Robert Goldman, MD, PhD, DO, FAASP.When combined with other B-complex vitamins including folate, B6, andB12, choline may help lower homocysteine, an amino acid linked to bothAD and cardiovascular disease. Research at Chicago’s Rush Institute ofHealthy Aging finds that people low in niacin (vitamin B3) are 70percent more likely to develop Alzheimer’s than those with higherniacin levels, so look for a well-balanced B-complex in your dailymultiple.

Related to lecithin that occurs naturally in thebrain, “phosphatidylserine (PS) belongs to a special category offat-soluble substances called phospholipids, which are essentialcomponents of cell membranes,” says Allen S. Josephs, MD. “In peoplewith Alzheimer’s PS has been shown to improve mental function, such asthe ability to remember names and to recall the location of misplacedobjects,” making PS one of the few known nutrients that may be usefulfor those with advanced AD.
