Brain Helpers, Part 2a

Besides the categories of eat, sleep, move, use it, and be social (covered in Part 1), science has found other ways we can repair, protect, and grow our brains. Here are some of them. I've divided these suggestions into physical and mental to keep posts small.

Physical things we can do to repair, protect, and grow our brains

Keep hydrated to clear out waste and increase communication speeds. Dehydration leads to drop offs in short term memory, numerical ability, and attention as well as causing generally slower cognitive functioning and confusion.

Get enough sunlight. Lack of sunlight brings on neurotransmitter imbalances and cognitive impairment.

Floss. Gum inflammation has been linked to brain inflammation. Also, keeping our teeth (1) in our mouths and (2) pain-free means we’re able to chew healthy foods.

Reduce physical stress to reduce mental stress. Practice the relaxation response (engaging the peripheral nervous system) through meditation, yoga, tai chi, progressive muscle relaxation, etc.

Reduce environmental stress. This can be done through opening up cramped spaces, decreasing clutter, bringing in plants, and doing what you can to breath clean air (changing filters, using an air purifier).

Avoid alcohol and smoking. Smokers have thinner cerebral cortices than nonsmokers, and drinking results in reductions in overall brain volume with the damage increasing the more you drink.

Rapid Cycling

To earn a rapid cycling badge, a person has to have four or more episodes in a year. Good times! I can’t begin to imagine what that’s like with full-blown mania. Hypomania and depression are enough, thanks! Before I got an accurate diagnosis and serviceable meds, I rarely went two weeks before starting a new episode. Up, down, up, down, up, down. It took years of work to figure out my baseline, i.e., what it feels like to just be me. I still have 4–10 days every few weeks when I’m very up, very down, or first one and then the other. I know some of my triggers: stress, lack of sleep, too much alcohol or caffeine. But some episodes come out of the blue. Rapid cycling means you never know. It means you can be in the middle of an exceptionally bad day before you realize, “Oh, this is depressive irritability” or whatever. And then you’re supposed to have the presence of mind to apply the tools that help you minimize any damage. Which is to say, it gets the jump on you, and because...

What Bipolar Does to the Brain

I’ve been researching what bipolar does to the brain and seriously—fuck. There’s both a lot more research than my 25-year-old B.A. in Psychology could assimilate and not nearly enough. A layperson’s book on the subject is sorely needed. Here’s the gist. * There’s solid evidence that the dysfunction during depressive and manic states causes changes that persist into our baseline states. * There are several neurotransmitters involved: dopamine, norepinephrine, serotonin, GABA (gamma-aminobutyrate), glutamate, and acetylcholine at the least. And hormones that act like neurotransmitters are in the mix, too, like endorphins and oxytocin. * Brain structures yet discovered to be involved/affected include areas of the prefrontal and temporal lobes, the hippocampus, thalamus, and hypothalamus. * Bipolar affects both grey and white matter, meaning both the structural elements of the brain and the connective tissue between them. And by affects, I mean corrodes over time. There’s mor...

On Being Hypomanic

Hypomania means elevated mood and energy. When you see bipolar romanticized , it’s likely hypomania they’re talking about. Increased creativity and drive do lead to increased output, but also to obsession, neglecting loved ones and your own health. Six of the books I’ve written were first scrawled during hypomanic episodes. I know of which I speak. When I’m hypomanic, I think I’m smarter, funnier, stronger. I think I heal faster. I also have zero impulse control. Some people in hypomania go on spending sprees, gamble, or have a lot of sex. It is the worst time to make life decisions and almost impossible not to. Hypomania is addictive. It feels so good, until it doesn’t. In a depression, man, all I want is a little hit of that hypomania. Not just for the joy, the brightness, the buzz, but to feel jazzed about something, anything, to have drive and purpose. Hypomania is hard to give up (to slam the door on with long- and short-term medication) but treating the bad in this case ...
