Your brain loves lipoic acid!

I'm primarily a food first, supplements second kind of person. However, lipoic acid is a supplement I love to recommend. It's not something that you can readily find in food, but it does a whole lot of good, especially in the brain.

It can delay and prevent Alzheimer's disease, and dementia, in a variety of ways. It helps to increase acetylcholine levels. Acetylcholine is the neurotransmitter in charge of memory function. It helps to bind free radicals, preventing them from doing damage. It prevents the formation of proteins associated with inflammation.

Not a bad friend, is it?

The amount given in the two studies evaluating lipoic acid's effect on the brain was 600 mg per day.

Lipoic acid is also unique in that it has the ability to make other antioxidants more powerful. The authors of the article reviewed here suggested that in combination with curcumin, EGCG (active ingredient in green tea), and DHA (in fish oil and marine algae), lipoic acid could be a very powerful warrior in the fight against degenerative brain disease.

Hmmmm...anyone for some fish curry, with a green tea chaser?

Folic acid and brain health--don't forget it!

As my last post discussed, depression is not just about mood. It's about the integrity of neurons and the systems that support them. One very strong connection that research is increasingly supporting, is the link between depression and inflammation. Inflammatory markers commonly used to identify heart disease, such as homocysteine, are being correlated as well with depression.

Here, 27 subjects were divided into two groups. One group was given fluoxetine (Prozac) and folic acid, while the other was given fluoxetine and placebo. (Folic acid was given because it has been shown to help prevent elevated homocysteine.) Another 15 subjects were given nothing at all, for a basis of comparison.

As happens in cardiovascular studies using folate as an intervention, plasma homocysteine levels dropped with folate supplementation. The interesting finding, however, was that when subjects took the Hamilton Depression Rating Score, those who had received the folate showed greater improvement than those who only received the fluoxetine. There was no significant difference in serotonin levels, so the researchers concluded that folate was not affecting the mechanism by which fluoxetine works.

So the bottom line seems to be...you can't just fix depression with a pill. How you take care of yourself (i.e., how you choose to eat) can be a crucial factor in whether or not your brain works at its absolute best.

If you want to add more folate to your diet, here are your best food choices: fortified breakfast cereal, whole wheat products, meat, beans, liver, eggs, sunflower seeds, asparagus, leafy green vegetables, oranges, strawberries, melons.

Aging brains and medicine

How medications work at different points in life can be a very important consideration. I see many, many studies looking at the viability of antidepressant therapy in the elderly. Recently there seems to be a flurry of research looking at how to medicate (note I did not use the word "treat") depression when it occurs as a comorbidity with diagnoses such as stroke or Alzheimer's disease.

In this study, the naturalistic finding was that as rats (and probably humans, too) age, the rate at which they are able to generate new neurons declines. The survival rate of those new cells starts to deteriorate as well.

The good news is that the response to fluoxetine (Prozac) was the same across the board.

The bad news is, that in none of the groups, even the young rats who had a better ability to make new neurons, did fluoxetine enhance that ability.

Hmmm...is it just me, or does it make sense that if a medication is going to work, it needs some brain cells to work on?

Sneak peek at new drug booklet

This study gives new meaning to the term, "mama's boy"...

Several years ago I was diagnosed with uterine fibroids. For all of my medical knowledge and connections, I was very distressed to learn that the treatments for this very common gynecological condition seemed to be very crude and invasive. There really wasn't much research into gentle, natural, or nutritional solutions. Every physician I spoke to just wanted to give me a hysterectomy, despite my young age. Some couldn't figure out why I wouldn't consent, given the fact I was not going to have children and my uterus was, therefore, essentially useless and unnecessary.

When I shared my situation with another female friend, she immediately said, "Well, if it was men who got fibroids on THEIR reproductive organs, you can guarantee there would be a gazillion dollars devoted to researching any possible way to treat them without removing the affected body part!"

Ever since, when I see some kind of gender inequity in medicine, I think of that conversation and remind myself that, unfortunately, sometimes men have to hurt in a unique and most unexpected place in order for them to think more creatively about how they treat women, personally and clinically.

This study is about depression and not fibroids, but it makes my point. Something I find very frustrating with my work in polycystic ovary syndrome is the reluctance on the part of some endocrinologists who treat the disorder to acknowledge the extreme anxiety, depression, and mood swings this disorder promotes. Even though 85% of the over 1,000 women who answered a survey on my website reported at least one of these problems, there are physicians who will flat out say depression is not part of the disorder. Or, rather than trying to understand what may be driving the depression, they simply write a script for an antidepressant.

Well...here's what might happen if you treat depression so superficially. Female rats were treated, throughout pregnancy and lactation, with fluoxetine (Prozac). Later on, the sexual behavior of their male offspring was observed. They appeared to have less incentive to participate in sexual activity. This lack of libido wasn't coming from any measurable, explainable change in hormones, these guys just didn't seem to want any.

With all due respect, knowing that fish oil/omega-3 fatty acids are a great option for depression as well as promoting libido, this kind of problem simply shouldn't be something we have to encounter or research. Except to identify and define precisely why we shouldn't be encountering or researching it.

Oh! And if you're male and you're feeling a little uncomfortable while reading this, you've just experienced what every woman in history has felt when she was told she had to have a hysterectomy that may have been unnecessary. Welcome to the world of medicine without compassion.

"Going up in smoke: tobacco smoking is associated with worse treatment outcomes in mania."

Bipolar disorder, to me, is a fascinating disorder. It seems to affect some very intelligent and creative people, and that, I believe, is precisely why it is so hard to treat. The manic episodes it can produce can be part of the thrill of having the disorder. I've had more than one client who accepted medical treatment for bipolar disorder complain that the medication took away the "edge". People started to ask if anything was wrong. We kind of like manic people for their charisma, for the creative performances, work output, etc., that they give us. And, because mania is a natural kind of high, giving it up can be somewhat of a chemical straight jacket.

However, bipolar disorder is also neurodegenerative. Meaning if it progresses unchecked, all that extra brain energy that's requiring oxidation of glucose to fuel all those charismatic neurons is also creating a process that's not unlike a "rusting out" of the brain. So, if we want to preserve the creativity and contributions of people born with this kind of hardwiring, we have to work harder to understand the hardwiring, and develop medications that don't leave people feeling zombied. Plus, we have to encourage lifestyle choices that promote longevity.

One of the worst risk factors, it appears, (in other words, a group of people we now know we have to work extra hard to learn how to help), is people with bipolar disorder who smoke. In this study, what was found was that the subjects who smoked did not respond as well to the medications they were given.

What is really interesting about this study, is that the medications tested happened to be antipsychotics that have been found to be helpful in some cases of bipolar disorder. No traditional mood stabilizers, such as lithium, were used. I wish that had been included in this study, because this study may not be saying that bipolar smokers have worse treatment outcomes, as much as it says when a patient is diagnosed with bipolar disorder who smokes, they may do better with a different category of medication.

Our patients depend on us to be diligent with scientific process and not let our bias interfere with their well-being.
