I'm at risk for both macular degeneration and Alzheimer's disease. I've read that more EPA than DHA is good for macular degeneration, but the reverse is true for Alzheimer's. What do you recommend?

I heard that Theracurmin, a form of curcumin, was shown to help with memory, but it's expensive. Does Theracurmin really improve memory and is it worth it?

Fish Oil and Alzheimer's Disease
The evidence is mixed on whether fish oil can help people with Alzheimer's disease. A benefit was seen in a study reported last year, but a recently reported study found no benefit with fish oil combined with antioxidants. More details are found in the "What It Does" section of the Fish Oil and Omega-3 Fatty Acid Supplements Review >>
Vitamin D & Alzheimer's Disease
Older people with insufficient levels of vitamin D had nearly triple the risk of developing Alzheimer's disease that those with sufficient levels, according to a recent study. Those with the lowest levels also experienced a faster rate of cognitive decline. Get the details and information about optimal vitamin D levels in the "What It Does" section of the Vitamin D Supplements Review, which includes our Top Picks among supplements.
Can Vitamin D Boost Cognition?
Middle-aged people with low levels of vitamin D were given high-dose vitamin D for four months. Find out if this boosted their cognitive performance in the Alzheimer's disease, dementia, memory and cognitive decline section of the Vitamin D Supplements Review. (Also see our Top Picks for vitamin D.)
Folic Acid for Cognition
Giving folic acid to older people with relatively low levels of blood folate resulted in improved cognitive performance, according to a recent study. For details, see the "Memory, Cognition, and Alzheimer's Disease" section in the B Vitamin Supplements Review >> (Also see our Top Picks for folate and other B vitamin supplements.)
B Vitamins for Cognition
Increasing vitamin B-12 intake by those deficient in B-12 can help slow age-related declines in memory and cognition, but the dose needs to be sufficient, as suggested by a recent study. For details see the Memory, Cognition, and Alzheimer's Disease section of the B Vitamin Supplements Review. Also see our Top Picks for B-12 and other B Vitamins.
Lower Risk of Dementia Through Foods
A 20-year study showed that the risk of Alzheimer's disease and other forms of dementia was 76% lower in people who ate more of certain foods. Find out what they ate and learn if supplements can help in our answer to the question: Do any supplements really help with brain function, like memory and cognition?
Alzheimer's Changes Slowed with B Vitamins
A combination of B vitamins was found to slow brain loss in areas of the brain associated with Alzheimer's disease. This same combination of vitamins has also been shown to slow cognitive decline. Get the details on who may (or may not) benefit, dosage, plus test results for over 35 B vitamin supplements in the updated B Vitamin Supplements Product Review >>
Does Ginkgo Improve Memory?
The evidence for Ginkgo biloba in preventing and treating Alzheimer's disease and other dementias has become fairly negative. But is there still hope for its use in improving memory in healthy individuals? The answer seems to be in, according to a new analysis of 10 placebo-controlled trials in healthy people. Get the answer in the update to the Ginkgo Supplements Review.
Vitamin D & Alzheimer's
A seven-year study of women over age 75 found those with higher intakes of vitamin D from their diets were 77% less likely to develop Alzheimer's disease. The amount of vitamin D intake associated with this large benefit was actually fairly modest. Get the details in the updated Vitamin D Supplements Review, which includes our product tests and quality ratings. More >>
Ginkgo Fails Alzheimer's Trial
Over two thousand people with memory complaints were given Ginkgo biloba extract or placebo as part of a five-year study. The results, published this week, showed no difference between the groups in the percentage who eventually developed Alzheimer's disease or dementia. See how this compares to other studies of ginkgo in the updated Ginkgo Biloba Supplements Review, which includes our tests and reviews of ginkgo products. More >>
Fish Oil / Alpha-Lipoic Acid for Alzheimer's
Up To a Point, Alzheimer's Risk Falls with Vitamin D
A new study shows that, up to a point, the risks of developing Alzheimer's disease and other forms of dementia fall with higher blood levels of vitamin D. However, the research also clarifies that exceeding a certain blood level of vitamin D provides no further benefit. In fact, additional research suggests that too much vitamin D can have negative effects. The message: Make sure you have a sufficient, but not excessive level of vitamin D. For details about these levels, as well as results of our tests of vitamin D supplements, see the updated Vitamin D Supplements Review >>
Resveratrol for Alzheimer's Disease?
High doses of a synthetic resveratrol stabilized a marker of disease progression in people with mild to moderate Alzheimer's, a recent study reports. However, more research is required to determine if resveratrol is effective for Alzheimer's. Get the details about this and other studies with resveratrol, and our tests and comparisons of products, in the Resveratrol Supplements Review >>
Folic Acid Supplementation Mitigates Alzheimer's
A recent study in people with Alzheimer's disease found that folic acid supplementation decreased inflammation and slightly improved mental functioning. However, participants began the study unusually low in folic acid relative to normal U.S. levels. For more details see the B Vitamin Supplements Review >> Also see results of a folate/B-12 study which showed reduced brain shrinkage in Alzheimer's patients.
Vitamin E/Selenium & Alzheimer's
A long-term study among men in the U.S. found that giving high doses of vitamin E and/or selenium did not significantly affect their risk of developing dementia. The study was part of a larger study which found that these supplements increased the risk of prostate cancer, type 2 diabetes, hair loss, and dermatitis. For details, see the "Alzheimer's disease/dementia" section of the Selenium Supplements Review >>
Green Tea & Cognition
Green tea consumption has been associated with a lower prevalence of cognitive impairment in older adults. However, a recent study evaluating the effects of a green tea powder on older adults with Alzheimer's disease and other forms of dementia failed to show a benefit. For more information, see the "What It Does" section of the Green Tea Review >>
Does Lithium Prevent Dementia?
A new study found the risk of developing dementia to be significantly lower in areas with higher levels of lithium in the drinking water. This finding is consistent with a study that found low-dose lithium to stabilize patients with Alzheimer's disease. Details about these studies are in the "What It Does" section of the Low-Dose Supplements Review, which includes our Top Picks among low-dose lithium supplements.
Niacinamide for Alzheimer's Disease?
Niacinamide (a form of niacin) has been promoted as a way to protect against memory loss associated with Alzheimer's disease – a claim based on studies in mice. A recent study put this to the test in people. See the results in the "Niacin" section of the B Vitamin Supplements Review >>
Powerful Combination for Alzheimer's
B12 for Cognition
Numerous studies show that getting adequate intake of B vitamins, such as B12, and, perhaps, omega-3 fatty acids from fish, may slow age-related declines in memory and cognition. But not everyone should expect a benefit, as shown in a recent study. For details, see the Memory, Cognition, and Alzheimer's Disease section of the B Vitamin Supplements Review. (Also see our Top Picks among products.)
Vitamin E Helps Alzheimer's Patients
A new study suggests that high-dose vitamin E can help people with Alzheimer's disease retain their ability to perform activities of daily living (such as dressing) for several months longer than those given placebo, reducing caregiver time. A similar dose of vitamin E has been shown in other studies to slow the progression of the disease in some people and to reduce the rate of conversion to Alzheimer's among people with mild cognitive impairment. For details -- including the dose and form of vitamin E used and our tests of supplements on the market which can provide this dose -- see the update to the Vitamin E Supplements Review >>
