6 Takeaways from Research on Teen Brain Development

Not every parent is the brain research junkie I am, so I thought I’d sum up some important findings from current research into teen brains. It turns out that everything your parents thought they knew about your teen brain was probably wrong. Such is the way of science that some of the information below will be wrong soon, too, but science is making progress on understanding what sort of beast we’re dealing with once the hormones hit.

In short summary:

  1. The teen brain is changing rapidly
  2. Decision-making abilities are not fully formed
  3. Social connections matter more, for better and for worse
  4. What teens put in their bodies can have a permanent effect on development
  5. Teens need sleep!
  6. Teens need adults

In longer form:

The teen brain is changing rapidly

It used to be thought that teens were pretty much done being formed and it was All Their Fault when they didn’t make good decisions. More recent research throws that idea into the garbage bin of history. Teen brains are going through huge changes, and are significantly different from adult brains well into their twenties. Where childhood was a time of forward growth and learning, the teen years are a confusing time of reorganization, throwing stuff out, and trying out new, incompletely formed abilities…

Decision-making abilities are not fully formed

…Such as decision-making. Remember when your child was two and said, “I can do it for mySELF!”? Now your teens really can do it for themselves, sorta. They have big capable bodies, adult-size sentences come out of their mouths, and many have suddenly developed a very advanced case of strong-opinion-itis.

The thing is, their brains don’t work like adult brains yet. The much-prized pre-frontal cortex of the adult human is still developing and underused. Teens tend to base their decisions on emotion, which is why they seem to change their decisions daily, hourly, and sometimes within the same sentence. When teens do make well-thought-out decisions, it’s hard work for them, much harder than for adults.

We adults have the unenviable task of supporting them in their decision-making and watching as they make bad decisions. We have to let them make bad decisions and watch them fail. And hardest of all, we have to figure out when it’s time to step in and be the “bad guy” because a decision is too disastrous to let go.

Social connections matter more, for better and for worse

I notice that articles for parents are almost always about the negative effect of teens’ need for social connections and confirmation, but really, this is largely a good thing. We want our teens to learn to be part of a social group that requires them to control their own impulses and make decisions about group participation. As adults, they will no doubt have to stand in line at the DMV, and these skills will come in handy.

We parents can support the good side of this need for social acceptance. One wise mom told me that she made sure that her house was always stocked with snacks and she was available to give rides…that way she knew what sort of trouble her kid was getting into. Another wise mom made sure to dole out hugs to all the teens that came to her house, making it clear to them that she trusted them and understood their need for social connections.

What teens put in their bodies can have a permanent effect on development

I am in no way an anti-drug crusader, but the research I’ve read should definitely give us all pause. Vaping, for example, seems relatively innocuous. But it turns out that kids who vape on a regular basis essentially turn themselves into permanent addicts. Their brains adapt to the nicotine and show permanent changes. And kids may play around with smoking weed (especially now that it’s legal in so many places), but heavy use results in irreparable changes to teens’ brain functions. This all goes for prescription drugs as well, so the early teen years are a good time to reassess. Educate yourselves, and your teens, about health, nutrition, and brain development.

Teens need sleep!

Another way of saying this is: Teens aren’t lazy! (Well, not necessarily.) They need more sleep than most of them are able to get. I highly recommend weekly planning meetings with your teens, and one of the topics can be “how are you going to get enough sleep this week?”

Teens need adults

You may be reading this still shaking from yet another interaction where your teen treated you as something lower than the dirt they were walking on. Your teen may ignore you, may make fun of you, may criticize your “mom jeans,” and may infuse all family activities with Attitude. However, your teen needs you, and this is not the time to write them off. Although helicoptering isn’t the answer, checking out isn’t, either.

No matter what, remember that when your teen looks back from adulthood, they are going to remember that you were always there supporting them. They are going to remember the advice you gave them. They not only will probably forgive you for most everything they blame you for now; they will probably also appreciate how right you were in some instances.

So we parents just have to power through this. We have to know that we are important and feel confident that we are doing our best to support our teen’s developing brain and body. Though you may feel that you’re getting performance reports from a boss who hates your work on principle, it’s a job we have to continue to do with love and confidence.
