Taking a daily omega-3 supplement for about five years doesn't seem to lower the risk of heart attacks, strokes, or heart-related death in healthy people over 50.
Taking fish oil supplements with EPA and DHA every day for six months might change your cholesterol levels about the same as taking a low dose of a common heart medication called atorvastatin—but it...
Taking B vitamins and omega-3s together might slow down early Alzheimer’s disease, but only if you already have enough omega-3 in your body when you start.
Some scientists think that taking B vitamins and omega-3s together might help slow memory loss in people with early memory problems, because B vitamins help turn one type of fat in the brain into...
Taking B vitamins won't help your memory or thinking if you don't already have enough omega-3s in your body — it's like trying to start a car with no gas, even if you turn the key.
If you're an older adult with mild memory problems, having more DHA (a type of omega-3 found in fish) in your blood might make B vitamins work better to help your brain, and DHA seems to help more...
For older people with early memory problems, taking B vitamins for two years might help slow memory loss and delay Alzheimer’s — but only if their blood already has high levels of omega-3 fats. In...
When people with early memory problems have more random brain activity in the area that handles memory, their memory and thinking skills tend to get worse—not better. This might mean their brain is...
Taking omega-3 fish oil supplements daily for two years doesn't seem to change the brain's natural low-level activity in people with memory problems or dementia, at least not in the way we measure it.
People with Alzheimer’s who also have abnormal protein clumps called Lewy bodies tend to have worse memory, thinking, and language skills at the start of their diagnosis, compared to those with only...
People with Alzheimer’s who also have Lewy bodies don’t have more of the Alzheimer’s proteins (amyloid and tau) than those without Lewy bodies. Their faster mental decline is probably because the...
Scientists have found a blood test-like method that can detect a specific brain problem called Lewy body pathology in people with Alzheimer’s, and it’s accurate over 96% of the time — meaning it...
People who have both Alzheimer’s and another brain condition called Lewy bodies show more severe energy loss in certain back parts of the brain than people with just Alzheimer’s, which means the two...
People with Alzheimer’s who also have another brain condition called Lewy bodies tend to forget things and lose mental skills 15% faster than those with just Alzheimer’s. This was measured using...
People who are starting to forget things as they age—before they get full-blown Alzheimer’s—already show lower energy use in two specific brain areas. This suggests those areas are the first to be...
People who are aging and having trouble with memory or thinking tend to have a medium amount of a protein called tau in their spinal fluid—more than healthy people but less than those with...
People with early memory problems as they age show the same brain changes as people with Alzheimer’s disease—like certain proteins in spinal fluid and how the brain uses sugar. This might help...
People whose memory and thinking skills decline with age show less energy use in certain brain areas that are also affected early in Alzheimer’s disease — suggesting these two conditions might share...
People with Alzheimer’s disease have more tau protein in the fluid around their brain than older adults with mild memory problems or healthy people, which suggests this protein might be a sign of how...
For adults with blood sugar problems, taking insulin glargine every day and omega-3 supplements for more than six years doesn't seem to slow down memory loss or prevent dementia.
Giving fish oil to older mice helps a little with keeping their brain cells flexible, but it doesn't change the levels of certain brain proteins linked to Alzheimer's.
Taking fish oil supplements may help boost a protein in the brains of older mice that stops brain cells from dying, which could help keep their brains healthier.
Older mice have less of a healthy fat called DHA in their blood and brain than younger mice, but giving them fish oil helps bring those levels back up.
Giving fish oil to older mice for three weeks helps fix their brain cells' energy production, which normally gets weaker as they age.
