Occasional forgetfulness is a normal part of life. We’ve all had the experience of walking into a room for something only to forget what it is as soon as we walk in. This is a blip in our working memory.

Working memory is the brain system that allows us to process and hold information for immediate use. For teens, minor memory or attention issues are often a regular part of their development, as the part of the brain mainly responsible for working memory (the prefrontal cortex) is still developing.^[1]

But while occasional forgetfulness or concentration issues are normal, an ongoing pattern of them could point to deeper working memory problems. Challenges with memory, concentration, and attention can be frustrating and concerning for both teens and their parents. To help you better understand working memory problems, this page will explore:

What working memory is and how teens use it.
Signs that your teen may be finding it hard to retain information.
The common causes of working memory problems in teens.
What helps support teens with executive dysfunction.

What Is Working Memory?

Working memory is our brain’s ability to temporarily hold information in a form that’s immediately accessible.^[2] Think of it like a mental notepad where your brain writes out a small amount of information that’s available long enough to do something about it.

Working memory is one of the brain’s cognitive skills that help us learn, plan, problem-solve, and control our impulses. It also works alongside attention and other aspects of executive functioning, which allows us to organize our behavior and work toward a goal.

For teens, this executive functioning skill might help them:

Remember the beginning of a sentence while reading the end.
Follow several instructions in the correct order.
Complete a math problem with multiple steps.
Take notes while listening to a teacher.

So when your teen experiences challenges with working memory, it’s not that they’re lazy or lacking intelligence or knowledge. They might understand the information but have trouble keeping enough of it active in their minds to use it effectively.

Signs and Effects of Working Memory Problems in Teens

Not every teen with concentration problems or executive dysfunction will experience the same signs or effects in every situation. But there are some patterns to pay attention to that might point to your teen having working memory problems, such as:

Forgetting Multi-Step Instructions

Your teen might complete the first part of an instruction but forget what the next steps were. For example, you might ask them to put away their clothes, bring their laundry basket downstairs, and feed the dog. But they end up only putting the clothes away and forget the other two tasks.

This type of forgetfulness isn’t always intentional. The information may disappear from their mental workspace before they’ve had a chance to act on it. As a result, your teen might ask for directions several times, even when they appeared to understand them the first time.

Losing Track While Reading or Talking

Reading requires us to remember earlier words and ideas while processing new ones. Teens with working memory problems might reach the end of a paragraph without understanding what they just read. Because of these learning difficulties, they might end up needing to repeatedly reread the same passage or struggling to summarize what they learned.

Difficulty Completing Schoolwork

Working memory plays an important role in nearly every school subject and in academic success. So working memory problems can contribute to learning difficulties, especially when assignments require your teen to listen, organize, remember, and respond at the same time.^[3] If your teen has working memory challenges, they might start assignments but:

Leave them unfinished.
Lose track of deadlines.
Make errors despite knowing the material.

As a result, their school performance may not accurately reflect their knowledge or effort. They might study for a test and understand the subject at home, only to forget important information once they’re under pressure.

Disorganization and Misplaced Items

When your teen can’t keep track of everything they need to do, they might also experience problems with organization. They might regularly:

Leave textbooks at school.
Misplace completed homework.
Arrive at class without the correct materials.

A messy room or forgotten assignment doesn’t mean there should be automatic concern that something’s wrong with their brain function. But when there’s repeated disorganization that interferes with their functioning, this may be a sign of working memory problems to look into.

What Causes Working Memory Problems?

Just as not everyone experiences the same signs of working memory problems, there’s also not one single cause. Mental health, sleep, stress, neurodevelopmental differences, and environment can all affect your teen’s cognitive skills.

ADHD and Executive Dysfunction

Research shows that attention-deficit hyperactivity disorder (ADHD) can often be associated with executive dysfunction and deficits in working memory and short-term memory.^[4] ADHD can affect your teen’s ability to:

Pay attention.
Resist distractions.
Manage their time.

For example, ADHD working memory challenges may cause your teen to remember they have homework while sitting in class, but forget it by the time they get home. Or they might start one task, become distracted by another, and then forget what they were originally doing.

But poor working memory doesn’t always mean your teen has ADHD. Just as having ADHD doesn’t automatically mean memory problems.

Anxiety, Depression, and Trauma

Your teen’s mental health can also affect working memory. When they feel anxious or depressed, their attention might be more focused on worries or fears, or they might have lower energy and concentration problems.^[5]

If they’ve experienced trauma, they might spend more mental energy monitoring their surroundings for danger or coping with intrusive memories and have less capacity for everyday information.

In these situations, the memory problems may be more about emotional overload, so treating the underlying mental health condition can play an important part in improving executive function.

Insufficient Sleep

Sleep supports:

Learning.
Focus.
Emotional regulation.
Healthy brain function.

According to experts, teens generally need between eight and ten hours of sleep each night, but many don’t consistently get enough.^[6]

Late-night homework, extracurricular schedules, early school start times, stress, and technology use can all reduce sleep. So before assuming that your teen’s symptoms reflect a disorder, consider whether they’re getting enough sleep.

Learning Differences and Environmental Overload

Language-processing difficulties, reading disorders, or other learning differences may sometimes appear to be memory problems. For example, your teen might not be able to retain directions effectively if they didn’t have enough time to process the information in the first place.

The environment can also matter. Working memory may become overloaded when a classroom is noisy, or several people give instructions at once.

What Supports Working Memory Problems in Teens?

Support for working memory problems often depends on what’s causing them. Some teens may need:

Better routines.
School accommodations.
Organization tools.

Others may benefit from therapy to address mental health concerns that might be making it harder to focus and retain information.

The most effective approach usually combines skill-building with support across home, school, and, when needed, treatment. Below, we’ll cover some ways you can support your teen with memory improvement.

Break Tasks Into Smaller Steps

Give your teen one or two directions at a time, rather than long instructions. Check with them that they understood by asking them what they’re going to start with. Then help them break larger assignments into smaller deadlines. For instance, if a teacher assigned a research paper, help your teen separate the topic selection, research, outline, first draft, and final revision into individual steps.

Use External Reminders and Organization Tools

If your teen struggles with working memory, support them by encouraging the use of external tools and reminders. Some helpful supports might include:

Written checklists.
Calendars.
Visual schedules.
Color-coded folders.

You can also help them create a designated space for the things they most often forget, like backpacks, chargers, and school supplies.

These tools can improve organization and follow-through. Teens are also more likely to use a system consistently when they help choose and set it up.

Strengthen Study Skills

Effective study skills can reduce the pressure placed on working memory. Instead of trying to hold too much information at once, help your teen organize learning into smaller and more active steps, like studying in shorter sessions or using flashcards. You can also help them review assignment instructions before turning in work and create a quiet space for them to study.

These strategies may support memory improvement while also helping teens better understand how they learn.

Seek Therapy

While therapy doesn’t simply “fix” working memory, it can help address any underlying emotional, behavioral, or attention-related concerns. Some helpful therapies that can support attention and memory improvement include:

Cognitive behavioral therapy (CBT): CBT can help teens recognize thought patterns and behaviors that contribute to avoidance, distraction, or feeling overwhelmed.
Dialectical behavior therapy (DBT): DBT teaches skills related to mindfulness, emotional regulation, and distress tolerance. These strategies may help teens remain focused when strong emotions would otherwise take up much of their mental energy.
ADHD-focused treatment: When ADHD working memory challenges and executive dysfunction are present, treatment may include behavioral strategies, executive function coaching, therapy, medication management, or a combination of approaches.

Treatment should be individualized because two teens can show similar working memory problems for very different reasons.

Working Memory Problems in Teens FAQ

When teens experience working memory difficulties, many parents wonder what causes them and whether they should be concerned. Here, we’ll address some of the most common questions we hear from parents about poor working memory, ADHD, testing, and treatment.

What causes poor working memory?

There are many possible causes of poor working memory. ADHD, anxiety, depression, trauma, chronic stress, inadequate sleep, learning differences, or an overstimulating environment can all contribute to attention and concentration problems.

Because several concerns can cause similar symptoms, it’s important to consider the teen’s emotional health, sleep, development, learning needs, and functioning across different settings.

How do you test working memory?

There are a few ways to test working memory. One of the most common tests is complex span tasks. Complex span tasks require you to remember a set of items in the correct order while also doing another unrelated task.^[7] There are different types of complex span tasks that measure issues within working memory. Testing may involve tasks that ask your teen to repeat numbers in a particular order, remember visual patterns, follow multi-step directions, or mentally organize information.

Does poor working memory mean my teen is not intelligent?

No, poor working memory doesn’t mean your teen is unintelligent. Working memory is not the same as intelligence. Your teen can be creative, insightful, and capable of understanding complex ideas while still finding it hard to hold information in their mind. Appropriate tools and support can help them show what they know more consistently.
