Millions of baseball fans will tune in tonight for the opening game of the World Series. Boston Red Sox versus St. Louis Cardinals. Sportswriters are saying it will be an interesting series between two well-matched teams. Football fans have it easy. They have to sit through just one big game to decide the year’s champion. For us baseball fans, it could take seven games spread over nine days to determine this year’s champion. That means fans need to approach the series as a marathon, not a sprint. Pay attention to sleep, exercise, food, alcohol, and emotions. The Red Sox and Cardinals are two very likable teams. Commentators point out that these guys play the game the “right way.” The players themselves say it’s going to be fun. Let’s see if we fans can remember that baseball is a game. This World Series should be fun to watch. Whoever you’re rooting for, have fun watching.
For many people, a late-night “snack” is a daily habit. There are two types of nighttime eating disorders. Sleep-related eating disorder is a highly-publicized though uncommon malady. People with this problem eat while sleepwalking or while in a twilight state between sleep and wakefulness. A better-documented problem is night eating syndrome, in which people do the majority of their eating late at night. It may affect 1 or 2 out of 100 people in the general population. Sleeping and eating are almost certainly connected, given the link between lack of sleep and weight gain. So getting plenty of sleep may be a helpful substitute for nighttime trips to the refrigerator. Being mindful of the problem and trying to identify its triggers, or stress-reduction techniques, may help avert trips to the refrigerator. Some people benefit from talk therapy.
The bombs that exploded on Monday near the finish line of the Boston Marathon killed three people, physically injured nearly 200 others, and traumatized thousands more. Recovery and healing are beginning for the families of those who died, for the injured and their families, and for others touched by this tragedy. For some, healing will be swift. For others it will be measured in small steps over months, and possibly years. The Marathon explosions will leave a legacy of emotional scars along with the physical ones, even among those who weren’t anywhere near the blasts. Some people who were at the scene of the explosions will undoubtedly develop post-traumatic stress disorder (PTSD). But PTSD is not the only response to frightening events. In fact, most people exposed to a trauma do not develop this condition. They may develop an anxiety disorder, for example, or become depressed. Most people do have some emotional response, but the majority develop no illness at all.
The term “chocoholic,” usually said with a smile, actually nods to a potentially serious question: can a person become addicted to food? There are three essential components of addiction: intense craving, loss of control over the object of that craving, and continued use or engagement despite bad consequences. People can exhibit all three of these in their relationships with food. It’s most common with foods that deliver a lot of sugar and fat — like chocolate — because they trigger reward pathways in the brain. In some animal studies, restricting these foods induced a stress-like response consistent with the “withdrawal” response seen in addiction. Much of the scientific discussion about food addiction has been sparked by the epidemic of obesity sweeping the U.S. and many other countries. Many people who are overweight crave food, lose control over eating, and experience negative health effects that should, but don’t, serve as a deterrent. The influence of stress on eating provides another link between food and addictive behavior.
December 21st marks the shortest daytime of the year in the northern hemisphere. Although the winter solstice marks a seasonal turning point, with daylight getting incrementally longer from here until June 21, for people with seasonal affective disorder it’s just another day of feeling lousy. People with this condition lose steam when the days get shorter and the nights longer. Symptoms of seasonal affective disorder include loss of pleasure and energy, feelings of worthlessness, inability to concentrate, and uncontrollable urges to eat sugar and high-carbohydrate foods. Although they fade with the arrival of spring, seasonal affective disorder can leave you overweight, out of shape, and with strained relationships and employment woes. A unique approach to this problem is the use of light therapy. It involves sitting near a special lamp that emits bright light for 30 minutes a day as soon after waking up as possible.
The Thanksgiving holiday began, as its name implies, when the colonists gave thanks for surviving their first year in the New World and for a good harvest. Nearly 400 years later, we’re learning that the simple act of giving thanks is not just good for the community but may also be good for the brain and body. Gratitude helps people refocus on what they have instead of what they lack. By acknowledging the goodness in their lives, expressing gratitude often helps people recognize that the source of that goodness lies at least partially outside themselves. This can connect them to something larger—other people, nature, or a higher power. In the relatively new field of positive psychology research, gratitude is strongly and consistently linked to greater happiness. Although some people may be born with a gift for expressing gratitude, anyone can learn how to do it. And this mental state grows stronger with use and practice. Here are some ways to cultivate gratitude.
One treatment that can help relieve depression and other mental or emotional problems is cognitive behavioral therapy. It guides individuals to change what they think. A related approach, called metacognitive therapy, helps individuals change how they think. Some preliminary but promising research suggests that metacognitive therapy may be useful for people with attention deficit hyperactivity disorder (ADHD). One study of 88 adults with ADHD found that metacognitive therapy led to significant reduction in ADHD symptoms in 42% of participants, compared to 12% who received supportive therapy. Keep in mind that metacognitive therapy is not yet a proven therapy. More research is needed on its effectiveness in different settings. But that means it doesn’t yet stack up to its elder cousin, cognitive behavioral therapy. And metacognitive therapy can’t be considered as a first line treatment for ADHD.
A friend once asked me about his son, who was about to turn 20. As a teenager, the boy had a quick temper. But now, on the brink of adulthood, the young man seemed to be getting worse. When a teen gets angrier as time goes by, it is a cause for concern. A 19-year-old is no longer a child, but neither is he or she a fully-fledged adult. This in-between state can extend well into the twenties. Some human development researchers have begun to call it “emerging adulthood.” No matter this stage is called, it presents a tricky time for parents and their children. Emerging adults must decide how much help they want or are willing to accept from their parents or anyone else. At the same time, parents must decide how much help it is reasonable to give.
For some people with depression that isn’t alleviated by medication or talk therapy, a relatively new option that uses magnetic fields to stimulate part of the brain may help. Called repetitive transcranial magnetic stimulation (rTMS), it was approved by the FDA in 2008. Although more and more centers are beginning to use transcranial magnetic stimulation, it still isn’t widely available. Transcranial magnetic stimulation directs a series of strong magnetic pulses into the brain. These pulses create a weak electrical current that can increase or decrease activity in specific parts of the brain. In two large studies, rTMS improved depression in 14% of people who underwent it, compared to 5% who underwent sham, treatment. The cost can range from $6,000 to $10,000, depending on the clinic and how many sessions are needed. Insurance may not cover the cost of treatment.
It is normal for children at some points in their development to be concerned about sameness and symmetry and having things perfect. But when such beliefs or behaviors become all-consuming and start interfering with school, home life, or recreational activities, the problem may be obsessive-compulsive disorder (OCD). Obsessions are irrational thoughts, images, and impulses that a person feels as unrealistic, intrusive, and unwanted. To relieve the anxiety caused by these obsessions, a youth may engage in compulsive rituals. Two main types of treatment are used to help youths better manage OCD: a form of talk therapy known as cognitive behavioral therapy, and medication. The ideal approach is to try cognitive behavioral therapy before turning to medication.
