Take inventory of your medications

Consider low blood sugar

Low blood sugar, or hypoglycemia, is a common cause of dizziness and light-headedness that can result in brain fog, says Sheetal DeCaria, MD, an anesthesiologist and a pain physician in Chicago. She points out that diet modifications may be in order. "Drinking some juice or eating a snack can help," Dr. DeCaria says. To keep blood-sugar levels stable, eat frequent meals and be prepared if you are out and about. Plus, learn the scientific reason you forget the most random things.

You're developing a chronic condition

Dr. DeCaria says chronic painful conditions—like fibromyalgia, a neuro-sensory disorder—can disrupt sleep and leave sufferers in fog. Their short-term memory and concentration falters due to their sleep issues. Finding ways to manage the pain will lead to better sleep. If you happen to suffer from "fibro fog," says Dr. DeCaria, take a look at your health habits. "The best treatment for fibromyalgia is actually lifestyle changes," she says. "My treatment recommendations focus on eating a healthy diet with lots of fruit and vegetables, exercising regularly (yoga and tai chi are beneficial due to the mind-body aspect), improving sleep, and meditation."

Menopause may play a role

Memory problems often affect women going through menopause and evidence exists linking loss of memory abilities during menopause. The Change can sneak up on you: Do you know the signs of perimenopause? A study in the journal Menopause, the journal of the North American Menopause Society, found that bouts of forgetfulness and struggles with "brain fog" for women in their late 40s and 50s may be due to menopause. "The most important thing to realize is that there really are some cognitive changes that occur during this phase in a woman's life," study author Miriam Weber, PhD, neuropsychologist at the University of Rochester Medical Center told the New York Times. "If a woman approaching menopause feels she is having memory problems, no one should brush it off or attribute it to a jam-packed schedule. She can find comfort in knowing that there are new research findings that support her experience. She can view her experience as normal." Learn how to tell if memory loss is a sign of Alzheimer's.

Realize it could be your pregnancy

Memory changes and brain fog can affect pregnant women. "About 25 percent of my pregnant and postpartum patients mention feeling scattered; they'll walk into a room and forget what it is they came to get," according to Melissa Dugan-Kim, MD, clinical instructor of obstetrics and gynecology at Northwestern Memorial Hospital in Chicago in Parents magazine. "So what if you feel as if you're losing your mind? Know that you're not alone—and remember this sanity-sparing advice."

If you have an MS diagnosis, learning or memory exercises may help, the site suggests. Speak to your physician about how to best manage your symptoms.
