You suspect your teen is using drugs. Maybe they’re not acting like themselves. Maybe they’re cutting school or shirking other responsibilities. Maybe their grades are dropping. Or their behavior is worsening. Maybe they’ve started hanging out with a bad crowd.

Maybe they’re being secretive and have even stolen money from your wallet. Maybe their physical appearance has changed with rapid weight loss or red eyes. Maybe you’ve noticed a change in their sleep habits, energy level and mood. Maybe you’ve actually found marijuana or other drugs in their room.

Naturally, the thought and possible confirmation of your child using drugs trigger a rush and range of emotions: anger, frustration, disappointment, sadness, fear.

If you think your child is using drugs, how do you approach them? Where do you start?

In October 2012, researchers at the Massachusetts Institute of Technology (MIT) set out to find if they could exercise complete control over habitual behaviors in mice.

By inhibiting a small region of the prefrontal cortex — region of the brain responsible for planning and thought — the scientists were able to break the mice’s habits, but, to their surprise, the mice immediately began forming new behavior patterns.

Until now, psychologists and behavioral therapists believed that habits were hidden in the illusive “subconscious.”

But the MIT study shows that the brain is not just aware of habits: it controls them completely, moment by moment. And no matter how long the habits have existed, we can now shut them off, as by the flip of a switch.

Ah, the holidays: Candy canes, cozy slippers, festive lights, family peace, marital joy, and grateful children.

Or not.

The holidays are stressful. There are the challenges of too much family, not enough family, not enough money, continual exposure to food and alcohol, and perhaps worst of all, the gap between our actual life and our fantasy life. As if gazing into the perfect happy scene within a snowglobe, we might fall into a trance of how our life should be.

We might feel torn apart by nostalgia and grief over the good times and good people of the past, and wracked with guilt and inadequacy for failing to create a more wonderful life for ourselves. We might feel scared about our dissatisfaction and hypnotized by the promise of fulfillment just beyond the hard glass.

Addictive and codependent behaviors thrive during this season of fantasy.

I remember when I was an active …

Just because someone doesn’t meet diagnostic criteria for substance abuse or dependence doesn’t mean drugs aren’t damaging their world.

There’s a space between normal behavior and an official diagnosis called “almost addicted” that has serious consequences, according to Dr. J. Wesley Boyd, MD, Ph.D, an assistant professor at Harvard Medical School and author of the book Almost Addicted: Is My (or My Loved One’s) Drug Use a Problem?

People who are almost addicted still struggle because of their drug use. They may have problems in their personal or professional lives. They also might meet criteria for drug abuse or dependence in the future — at which point it becomes tougher to treat. Intervening now can lead to healthy changes and prevent a full-blown crisis, said Dr. Boyd, also a staff psychiatrist at Cambridge Health Alliance.

What’s your weakness?

Is it cupcakes, potato chips, bread, a big bowl of pasta, cheese fondue, fried chicken, pizza, ice cream or something else?

Do you crave something creamy that melts in your mouth or a salty crunch that takes the edge off?

If you do, you’re similar to 100% of women and 75% of men who reported food cravings in the last year, according to a report in the Wall Street Journal.

Cravings, once considered the body’s way of signaling that we’re missing important nutrients, are now understood to be something quite different.  If they were merely a signal that we were short on, say, magnesium (a nutrient found in chocolate), then why do we tend to crave salty and sweet snacks, rather than healthier options of nutrient rich foods?

For a long while I was afraid to write things such as “I am mentally ill” or “I am bipolar.” I was afraid of labels.

By calling myself a manic-depressive would I trap my psyche in “sick” mode? By accepting my diagnosis of bipolar disorder, would I prevent healing? By writing the words “I am mentally ill,” was I holding myself to a place that I was, but not where I am now, or where I could go?

I spent a fair amount of time pondering this (I’m a natural ruminator)…. I thought about attracting bad karma by writing about my illness, about feeding my anxiety by connecting with others who also struggle with depression, about stifling my spirit by posing all of my questions and frustrations online in an effort to figure out and assemble this humongous, Anchisaurus (a kind of dinosaur) 500-plus piece puzzle of mental illness.

And then I arrived at this guess (because there are no answers): No.

As folks get ready to watch the Super Bowl on television this Sunday in the U.S., many of us will be joining or attending Super Bowl viewing parties. If you’re like most Americans, you’ll probably drive to get to that party.

But unlike most Sundays, when you drive this Sunday coming home from your Super Bowl Party, be especially careful. Why?

Because unlike other Sundays when a football game is televised, researchers found that both non-fatal and fatal car accidents increase 41 percent on average. The risk is highest within an hour of the game’s end, when most people are driving home.

What causes this rise in automobile accidents? Not surprising, alcohol was involved in most fatal injury accidents, as well as a majority of non-fatal accidents. Inattention and fatigue are two additional factors implicated.

Recovering from an addiction is probably one of the most difficult tasks a person can do in their lifetime. There is a whole industry that specifically addresses helping people overcome an addiction, whether it be from a drug, alcohol, or now, even a behavior.

Drug and alcohol addiction remain a serious problem in this country, as well as many others. Surprisingly, nearly 75 percent of all adult illicit drug users are employed, as are most binge and heavy alcohol users, according to the National Institute on Drug Abuse. In the United States, it’s estimated that companies and organizations lose up to $100 billion a year due to employee alcohol and drug abuse, according to the The National Clearinghouse for Alcohol and Drug Information. The destruction to a person’s private life, relationships, friends and family is often immeasurable.

Substance abuse and alcohol abuse treatments are effective and do work. Not only does it help the abuser, it also begins the recovery process to help them repair their relationships with others.

Stress can throw anyone off-kilter. But when you have a mental illness, you might be extra vulnerable. “The demands, pressures and expectations of the holidays can be felt more intensely by people with mental illness,” according to Darlene Mininni, PhD, MPH, author of The Emotional Toolkit, who works privately with individuals and speaks nationally on topics related to emotional health and well-being.

“Having a mental illness is the same as having any chronic illness,” said Elvira G. Aletta, Ph.D, a clinical psychologist and founder of Explore What’s Next, a comprehensive psychotherapy practice. So it helps to have a plan and take good care of yourself.

Here are nine tips for coping with the holidays.

You don’t have to be a rocket scientist to appreciate the link between sugar and depression.

Anyone who doubts the relationship need only to spend a night in our house and see what type of behavior happens when two kids consume 12-ounce cans of Coke or Sprite — and the demonic demonstrations that happen after a 7-11 slurpee, especially if it’s red or blue, or God forbid, a mix.

People who suffer from depression are especially vulnerable to sugar’s evil power. I am so sensitive to white-flour, processed foods that I can practically set an alarm to for three hours after consumption, at which time I will be cursing myself for inhaling the large piece of birthday cake at the party because I am feeling so miserable. That doesn’t stop me from eating dessert at the next gathering, of course, but the awareness between sugar and mood does help me better understand some of my crashes.

What, exactly, is going on inside our brain when we take a bite of that fudge cheesecake?

Take a minute and answer this question: Is anyone really normal today?

I mean, even those who claim they are normal may, in fact, be the most neurotic among us, swimming with a nice pair of scuba fins down the river of Denial. Having my psychiatric file published online and in print for public viewing, I get to hear my share of dirty secrets—weird obsessions, family dysfunction, or disguised addiction—that are kept concealed from everyone but a self-professed neurotic and maybe a shrink.

“Why are there so many disorders today?” Those seven words, or a variation of them, surface a few times a week. And my take on this query is so complex that, to avoid sounding like my grad school professors making an erudite case that fails to communicate anything to average folks like me, I often shrug my shoulders and move on to a conversation about dessert. Now that I can talk about all day.

Here’s the abridged edition of my guess as to why we mark up more pages of the DSM-IV today than, say, a century ago (even though the DSM-IV had yet to be born).
