More on zinc and depression



In my last post, I described a study in which zinc was shown to enhance antidepressant activity. In this study, rats whose depression and anxiety-related behaviors had been successfully treated with antidepressants were then placed on a zinc-deficient diet.

What happened?

They started to act anxious and depressed again.

We live in a culture that has created the mentality that if you're not feeling well, you go to the doctor, she prescribes you a pill, you take the pill, and you feel all better.

Unfortunately, pills can only work some of the time. And they tend to work best when you're using them in conjunction with healthy self-care behaviors. As far as I know, and I am a voracious consumer of psychiatric and neurological research, there is no pill developed that will overcome what you choose not to do.

Medication, in most cases, should be considered an ADJUNCT to treatment, not the ONLY solution to a medical problem.

The whammy here is that when you're depressed, it can be challenging to feel like doing anything for yourself at all. If you're not up to "healthy living" but you ARE motivated to take your prescription medication...at least consider taking a zinc supplement alongside the prescription. They are easy to find and inexpensive.

And they just might be what determines whether you crawl out of that whole.....

...or feel hopelessly stuck there.

A little red meat may help your depression


If you have depression, you are not depressed because there is a deficiency of antidepressants in your body...

...however...

...you may be depressed because you have some basic nutritional deficiencies. One mineral that is involved in numerous brain and nervous system functions, and that has been extensively studied with regards to its role in the development of depression, is zinc.

Various doses of zinc were recently shown to improve immobility time in rats. Immobility in a stressful situation is a common behavior in depression. (When you are not depressed, you have better decision making and response times when it comes to managing stressful situations.)

That's exactly what fluoxetine (Prozac), paroxetine (Paxil), imipramine (Tofranil), desipramine (Norpramin), and bupropion (Wellbutrin) do!

When zinc and antidepressants were administered together, immobility time was reduced by more than either therapy produced on its own.

Practically what that says is that:
(1) if you are at risk for, or have had a history of depression, emphasizing high-zinc dietary choices and/or zinc supplementation would be a smart strategy, and
(2) if you are on an antidepressant, supplementing with zinc would be important to be sure that you get enough medication to do the job without getting so much that you set yourself up for detrimental side effects.

In fact, it seems to me that it should be an automatic recommendation of any physician, when prescribing an antidepressant, to write "zinc supplement" in the script as well...

FYI, your best sources of zinc include: red meats, liver, and oyster. And, when the originating soil is in good condtion...wheat, sweet corn, lettuce, beans, nuts, almonds, whole grains, pumpkin seeds, sunflower seeds and blackcurrant. That's a lot of different options, something for practically everyone, meat eater or not!

Your medications and your genes


DNA and genetics are not my areas of specialty but I found this study very interesting and wanted to share it. Anyone who does have expertise on this...please respond!

Alprazolam (Xanax), a popular tranquilizer, was recently reported to "intercalate" with DNA. I'm providing a link to a Wikipedia piece on what intercalation is...in short, I gather it means that somehow Xanax incorporates itself into the structure of DNA itself. Which would mean, that it potentially changes how the DNA expresses itself. This finding prompted the research to issue caution about the random use of Xanax.

Makes me wonder when I see all these medications that are associated with weight gain, if other medications have the same ability? And it also makes me wonder if other compounds, even certain foods, might also affect DNA structure and function.

It's a whole lot more complex than "eat less and exercise more"...which is why I love reporting on this specialty so much! There is always something new and different to share that provides a potential answer to someone doing a Google search.

Do we need a kindler, gentler football?


I'm going to let the New York Times do the talking today. I hate to see stories like this, because every time I do.....I wonder how we could use some simple nutritional therapies to minimize the chances of this kind of tragedy? I don't think it's all about nutrition, but I do think a good chunk of it might be.

Here's hoping some day, someone in a place to take action on that sentiment, has the money and the connections to actually do so.

Alzheimer's, sleep, and diabetes--three very interesting amigos



I didn't realize until reading this abstract that Alzheimer's disease affects sleep patterns as well as memory. It makes sense, since adequate sleep is necessary in order to retain memory of information gained during the day.

The medication reviewed in this article is galantamine (Reminyl), and the authors suggest that it is important to time medication administration in order to gain maximum effectiveness and sleep. And, that certain medications help (and interfere with) sleep more than others.

Disrupted sleep can worsen diabetes. Since many people with Alzheimer's also have diabetes--in fact, the two diseases are starting to be recognized as being very strongly linked to each other--this connection between sleep and medication can be very important to understand.

My guess is that if you are on this blog looking for information about Alzheimer's, it is a loved one, not you, that the information is for. Here is the bottom line:
1. If your loved one had problems with sleep before being recommended or placed on medication, it might be a good idea to check with the prescribing physician to be sure this was taken into account when choosing which Alzheimer's medication to prescribe.
2. If your loved one has developed changes in sleep habits since starting an Alzheimer's medication, be sure to let the prescribing physician know.
3. If your loved one's diabetes has become worse despite diligent attention to medications and food intake, consider the influence of sleep or lack thereof.
4. Be sure to ask your physician and/or pharmacist if there is a time of day your particular medication needs to be taken for maximum effectiveness.

Which came first...the hair or the hormones?


This abstract caught my eye because I also have a blog about polycystic ovary syndrome (PCOS) and finasteride is sometimes used to treat the hirsutism (hair growth in women) that this syndrome often causes. It has now been observed to have antipsychotic properties and is being proposed as a treatment for psychosis.

Antipsychotics are increasingly being used to treat depression, and at least 85% of women with PCOS have some kind of anxiety, depression, or other mood disorder associated with this diagnosis. If you have PCOS, please do not jump to the assumption that I am saying you are psychotic. What I am trying to point out here is that there is a huge mind-body connection in the syndrome that is often ignored. Physicians can be so compartmentalized with their treatments that they focus on the acne, the hair, the infertility...and completely ignore the moods, the mood swings, the associated disrupted eating patterns...and then they and their patients wonder why treatment is not successful.

I am posting this abstract to challenge anyone who treats PCOS to figure out what is going on in the brain of the woman with PCOS since it is, after all, the brain that controls hormones. Rather than mess with hormones and create even more problems, why aren't we going to the source and looking THERE for potential solutions? Let's make this the day we shift our thinking.

I chose the photo I did not to be funny, demeaning, or hurtful. I did it for the benefit of those who truly do not understand what many women go through because of their PCOS. Hair growth can be devastating and lead to horrible issues with self-image. Long ago it was often called "diabetes of the bearded ladies". If you can imagine what it's like to look in the mirror and feel as though you're losing your femininity, often at a time when you're trying to conceive and desiring to be attractive to your partner...it's a situation deserving of much more attention than it often gets by physicians.

Factors potentiating the risk of mirtazapine-associated restless legs syndrome.


Restless leg syndrome (RLS) is a very annoying condition. I know, because I get it when I'm under stress. It strikes when I'm relaxing; my legs begin to move on their own as if I am a puppet and they are attached to strings.

Restless legs is officially classified as a sleep disorder. Those involuntary movements interfere with restful sleep. You can see the vicious cycle that can get started, as poor sleep can make a day more stressful, which can exacerbate restless legs, etc., etc.

So this article about risk factors for restless legs syndrome caught my eye on a recent cruise through the National Library of Medicine database.

In 181 records reviewed over a 3 1/2 year period, in individuals taking the antidepressant mirtazapine (Remeron), eight percent reported having RLS, tending to start within a few days of beginning mirtazapine therapy. This trend seemed to be more frequent if, in addition to mirtazapine, the individual was using tramadol and/or dopamine-blocking agents.

Be sure to let your physician know if you've noticed this syndrome developing. There are alternatives, pharmacological and non pharmacological, that won't steal your sleep in the name of making you feel better.
