blueberry juice

A small study in the journal Applied Physiology, Nutrition, and Metabolism showed an improvement in cognitive function, bloodflow to the brain, and brain activation in older people who drank concentrated blueberry juice every day for 12 weeks.

The 26 participants were healthy adults between the ages of 65 and 77. People who consumed more than 5 daily servings of fruits and vegetables were excluded from the study. Twelve participants consumed 30mL (less than a quarter cup) of the concentrated juice each day, while the other 14 received a daily placebo instead.

The participants did a variety of cognitive tests before and after the study period. Magnetic resonance imaging (MRI) scans collected information about bloodflow and brain function during these tests.

Participants in the blueberry juice group showed statistically significant increases in brain activity by the end of the study compared to those in the placebo group.

The study was led by researcher Joanna Bowtell.

High-Dose Vitamin D May Improve Cognition More Than Low-Dose Vitamin D

August 16, 2017 · Posted in Potential Treatments · Comment 

Woman taking vitaminVitamin D deficiency has been associated with dementia and cognitive decline, but supplements may help. In a study of 82 healthy individuals with low vitamin D levels, high-dose vitamin D supplements (4000 IU/day) improved visual/nonverbal memory more than did low-dose vitamin D supplements (400 IU/day) over 18 weeks.

The 2017 study took place in Canada, where short winter days can make it more difficult to get sufficient levels of vitamin D from sunlight. The higher-dose supplements raised blood levels of vitamin D compared with the lower-dose supplements.

Those who received the higher doses performed better at tests of visual memory such as the Pattern Recognition Memory Task and the Paired Associates Learning Task, but their performance on tests of verbal memory was not significantly different from those in the lower-dose group. This suggests that higher vitamin D levels are particularly important to visual/nonverbal memory.

The study by Jacqueline A. Pettersen was published in the journal Experimental Gerontology.

Vitamin D Deficiency Linked to Depression, But Supplements Helped

August 14, 2017 · Posted in Potential Treatments · Comment 

vitamin DA review article in the Journal of Affective Disorders in 2017 summarized findings linking vitamin D to depression. Researcher Gordon B. Parker and colleagues found an association between low vitamin D levels and depression. They also found that vitamin D supplements improved treatment in people with clinical depression and vitamin D deficiency.

Editor’s Note: Vitamin D supplements are an obvious recommendation for people who are deficient. What has not yet been resolved is whether vitamin D is helpful to people who are depressed but not vitamin D deficient.

In a 2013 study in the Australian and New Zealand Journal of Psychiatry, Nayereh Khoraminya and colleagues suggested that a 1500 IU dose of vitamin D3 combined with the selective serotonin reuptake inhibitor (SSRI) antidepressant fluoxetine was more effective than fluoxetine plus placebo in depressed patients who were not necessarily deficient in vitamin D.

Giving Infants Vitamin D Can Reduce Type 1 Diabetes

August 10, 2017 · Posted in Potential Treatments · Comment 

babyA 2001 cohort study in Finland showed that giving vitamin D supplements to infants may reduce their risk for type 1 diabetes. The data for the study, by Elina Hyppönen and colleagues in the journal The Lancet, came from 10,366 people born in 1966. Their mothers were part of a medical registry that collected information on vitamin D given to children during the first year of their lives.

Of the 10,366 people in Hyppönen’s study, 81 had been diagnosed with type 1 diabetes by the end of 1997. Those participants who were given vitamin D supplements during their first year of life were less likely to be diagnosed with type 1 diabetes than other participants. Those who regularly took the recommended dose at the time, 2000 IU daily, during their first year of life had significantly lower diabetes rates 33 years later.

TDCS May Improve ADHD Symptoms

August 9, 2017 · Posted in Potential Treatments · Comment 

tDCSTranscranial direct current stimulation (tDCS) is a therapy in which electrodes placed on the skull deliver a steady, low level current to the brain, changing its threshold for electrical activity. Anodal tDCS to the prefrontal cortex can improve working memory. In a small 2017 study in the Journal of Neural Transmission, Cornelia Soff and colleagues found for the first time that tDCS may improve symptoms of attention-deficit hyperactivity disorder (ADHD).

People with ADHD tend to have underactivation of the prefrontal cortex and deficits in working memory. The study randomized 15 young people aged 12–16 (three girls and twelve boys) to receive either real tDCS or a sham stimulation. The anodal tDCS was delivered at 1 mA targeting the left dorsolateral prefrontal cortex for 5 days. Those participants who received tDCS showed a reduction in inattention, impulsivity, and hyperactivity compared to those who received the sham stimulation. The effects were more pronounced 7 days after the stimulation, suggesting that tDCS’ effects may be long-term. Larger, more definitive trials are needed to clarify the effects of tDCS on ADHD, but these preliminary findings are promising.

NAD+ Supplements May Not Contain Much NAD+

vitamin B3

Vitamin B3 supplements might be a more effective alternative to NAD+ supplements.

NAD, or nicotinamide adenine dinucleotide, is found in all living cells. Its oxidized form, NAD+, has become popular as a nutritional supplement following a 2013 Harvard study that suggested it might slow aging in mice. However, commercially available NAD+ supplements may contain less than 100mg of NAD+, when ten times that amount would be required to produce any effect. NAD+ has not been tested in clinical trials.

Vitamin B3 is a better-tested alternative. A 2016 controlled clinical trial of a type of vitamin B3 called nicotinamide riboside (NR) found that this supplement was safe for humans and increased levels of NAD+. In the study by Samuel A.J. Trammell and colleagues in the journal Nature Communications, single doses of 100mg, 300mg, and 1000mg were all found to be safe. Larger doses increased NAD+ metabolism by greater amounts.

Check with your doctor before taking an NAD+ or vitamin B supplements.

Coenzyme NAD+ Postpones Aging in Mice and Worms

August 7, 2017 · Posted in Potential Treatments · Comment 

mouseAging cells seem to lose their ability to repair DNA, while the mitochondria that power cells also become less reliable. A coenzyme called NAD+ may be able to postpone these changes. NAD+, which is found in all living cells, naturally decreases with age.

A 2016 article by Evandro Fei Fang and colleagues in the journal Cell Metabolism reports that giving mice and roundworms supplemental NAD+ postponed cell aging and extended the lives of these animals.

The researchers hope this research might eventually help patients with Alzheimer’s and Parkinson’s’ diseases.

Single Dose of Modafinil Improved Memory in People in Remission from Depression

August 3, 2017 · Posted in Potential Treatments · Comment 

memory aidModafinil is a wake-promoting medication used to treat narcolepsy, but studies have also shown that it can improve cognition in people with schizophrenia or attention deficit hyperactivity disorder. It may also help people with lingering cognitive difficulties after recovering from a depression. A 2016 article in the journal Biological Psychiatry reported that a single 200mg dose of modafinil improved performance on tests of episodic memory and working memory (but not planning or attention).

The study by researcher Barbara Sahakian and colleagues included 60 patients who had recently recovered from a depression. They took some cognitive tests to establish a baseline of their performance. A week later, they were given either a placebo or a single dose of modafinil, and two hours later they completed the cognitive tests again. The modafinil group performed better on the memory-related tasks.

While side effects were limited, two participants who received modafinil had sleep disturbances that night.

Longer-term studies are needed to determine whether modafinil is safe and effective if taken over a longer period of time. Cognitive dysfunction can interfere with daily tasks such as work or school and put people at greater risk of relapse, so effective treatments have the potential to greatly improve quality of life for people in remission from depression.

Antipsychotic Drug Pimavanserin Seems to Reduce Psychosis in People with Alzheimer’s

August 1, 2017 · Posted in Potential Treatments · Comment 

elderly womanThe antipsychotic drug pimavanserin was approved by the US Food and Drug Administration last year as a treatment for hallucinations and delusions in Parkinson’s disease. Now it looks as though it may also help people with Alzheimer’s disease. Pimavanserin works differently than other antipsychotic medications—a selective serotonin inverse agonist, it acts at serotonin HT2A receptors to produce effects opposite to those that serotonin would produce at the same receptor.

In a trial of 181 patients with Alzheimer’s and psychotic symptoms, those who received 34 mg/day of pimavanserin had a significant improvement in psychotic symptoms in six weeks compared to those who received placebo.

Over 12 weeks of treatment, pimavanserin did not impair cognition, as atypical antipsychotics can do.

Pimavanserin was well tolerated. The most common side effects were falls, urinary tract infections, and agitation. Like other atypical antipsychotics, the drug carries a box warning from the FDA that there is an increased risk of death when the drug is used to treat older people with dementia-related psychosis.

The FDA has designated pimavanserin a breakthrough therapy and is giving it priority review. These designations can speed up the development and review of a drug and are granted when a drug looks like it will be substantially better or safer than existing treatments for a serious condition.

Picture-naming activity

In a study of 12 people with mild Alzheimer’s disease or frontotemporal dementia, transcranial direct current stimulation (tDCS) improved the participants’ abilities to name an object in a picture more than did a sham stimulation. TDCS is a treatment in which an anode and a cathode electrode placed on the skull are used to deliver a steady low level of electrical current to the brain. There is currently no treatment available to specifically target symptoms of dementia such as forgetting words.

The research by Howard Chertkow and colleagues was presented at the 2017 meeting of the American Academy of Neurology. In the study, participants received either 30 minutes of anodal tDCS targeting the parietal lobe of the brain or a sham stimulation.

They also received training in picture-naming. The participants were evaluated before stimulation, at the final stimulation session, two weeks after stimulation, and two months after stimulation. Compared to those who received the sham stimulation, those who received real tDCS improved at picture-naming, and maintained that improvement for two months.

Those who received tDCS also performed better at naming new pictures not included in the training, and were better able to remember a string of digits than those who got the sham stimulation.
