Improve Your Memory Without Hormone Replacement Therapy
If you suffer from brain fuzzies, forgetfulness, and a lack of concentration, and you’re in the menopause, the good news is that you don’t have to reach for hormone replacement therapy yet. Whilst the protective effects of estrogen on the brain have been documented, so have the risks, and for this very good reason, many women opt to go through menopause without taking any additional hormones. In fact, many experts advise women against going on hormone replacement therapy just for its’ memory enhancing effects. They cite the risks, and the lack of conclusive evidence that HRT prevents Alzheimer’s, in saying that is not, in and of itself, a reason to start hormone replacement therapy.
The good news is that in terms of memory, there are other hormones that have a vital influence, and you can do something about influencing these hormones with your diet and habits. The hormone in question is insulin. It is involved with regulating the body’s blood sugar levels. The blood sugar levels of the body are important in memory because our brains use glucose for energy. Without the energy to function - and for the brain, this is having enough glucose available - we can’t learn or remember.
And because our brain doesn’t make or store glucose, it relies on the presence of glucose in the body. And insulin is involved in regulating that.
But insulin does more than simply provide the brain with glucose. It affects memory and learning in other ways. Researchers believe that it produces a neurotransmitter involved in memory, acetylcholine, as a by-product. It also makes new connections in the hippocampus, which is involved in the creation of new memories about events you experience. Insulin also helps increase levels of norepinephrine, a neurotransmitter involved in attention and the ability to focus. Additionally, insulin opposes the effects of the stress hormone cortisol. Cortisol interferes with our ability for memory recall when we are under prolonged stress.
People with insulin resistance, such as those with metabolic syndrome, or type 2 diabetes, which is also associated with aging, can have these processes affected. When you are insulin resistant, your body produces increasing amounts of insulin to try and get the normal effect insulin has in the body. It’s not unlike a drug addict who has built up a tolerance to their drug of choice. Gradually, the body becomes less and less responsive to it, so more is needed for the ‘hit’. Thus with insulin, if you have too much circulating in your body, it becomes less sensitive to it, and so its’ effects are reduced.
To make matters worse, high levels of insulin in the body create correspondingly high levels of cortisol, the stress hormone. And in large amounts, cortisol is bad for the functioning of memory.
What Can You Do About It?
Exercising, three times a week, for about 20 minutes, really improves the way your body handles glucose, and has a protective effect against insulin resistance. Aerobic activity and other forms of exercise can help resensitize the body to insulin, and thus improve your memory.
Pay attention to your diet. Eating foods rich in fat, and refined sugars, contributes to the potential for insulin resistance. Eating foods high in fiber, and complex carbohydrates (not pasta!), is a much better choice.
