Memory loss usually happens as our age progresses. But in some cases, memory loss could be a problem in teenagers as well, due to various reasons. This, however, is not normal or healthy.

Memory loss could be for a short period or may last longer based on the cause behind it. While short-term memory loss may occur in some teenagers, long term memory loss is rare as it is caused due to medical conditions such as dementia and Alzheimer’s disease that mostly occur in the elderly (1) (2).

In this post, MomJunction tells you about the various reasons for short-term memory loss in teenagers and how you could resolve them.

What Is Short-Term Memory Loss?

Skipping minor details is normal. But if your teenager is often having a hard time remembering recent events and important information, they may be dealing with what is called short-term memory loss.

For example, if your child does not remember what they did during the day at school or if they often try hard to remember names or places they visit regularly, then they may be having short-term memory issues.

Next, we list a few symptoms to help you know if the teen has a memory loss problem.

Symptoms Of Short-Term Memory Loss In Teens

  • Asking the same questions repeatedly
  • Forgetting recent events and information
  • Unable to recall information that they heard or shared recently
  • Often misplacing things and spending time searching them

If such behavior is affecting your child’s day-to-day activities, or the child is lagging in school due to poor memory issues, you should find out the reasons behind it.

Possible Causes For Memory Loss In Teenagers

Causes for poor memory retention could vary from one teen to another. Some common causes are mentioned here.

  1. Slow learning ability: Some teenagers might be slow learners by nature, which could be the reason for their poor memory and lagging in academics when compared to their peers. Other characteristics of slow learners include
  • Lack of concentration
  • Poor imagination
  • Inability to express their ideas verbally
  • Poor social skills

Note that slow learners need not always have mental disorders. They may just need more time than others to process and understand the concepts.

With improved teaching techniques and extra attention from parents and teachers, memory issues could be resolved among slow learners (3).

  1. Medications: Certain medications may also interfere with the memory of your teenager. Tranquilizers, antidepressants, and blood pressure medications could affect memory. These medications produce a sedative effect, which could make it difficult for them to concentrate and remember information.
  1. Vitamin B-12 deficiency: A study on 3,156 children between the ages of five and 12 found that vitamin B12 deficiency was associated with grade repetition and absenteeism among children (4). Another study has found that low levels of vitamin B12 could be associated with neurocognitive disorders. So, vitamin deficiency could also be a reason for the sudden memory loss in your teenager.

Other symptoms of B12 deficiency include:

  • Numbness and tingling feeling in hands and legs
  • Anemia
  • Weakness
  • Fatigue
  • Inflamed tongue (5)
  1. Substance abuse: Studies found that substance abuse, such as alcohol and drug abuse, could lead to alteration of the brain structure and functioning. Heavy consumption of alcohol could also be related to a decrease in memory in adolescents (6).
  1. Stress and anxiety: The amygdala and hippocampus regions of the brain are important for processing emotions and retaining them as memories. These are also involved in learning and conditioning. Studies found that children who were exposed to stress and anxiety during their childhood showed alterations in the development of the amygdala and hippocampus, which could be the reason for memory loss during adolescence (7).

  1. Excess gadget usage: Although there is a need for further investigation, available studies suggest that prolonged usage of smartphones could affect the memory functioning in teenagers (8).
  1. Head injury: After a concussion, a brief loss of memory of the events before or after injury might occur. Other symptoms of a concussion include:
  • Headache
  • Dizziness
  • Attention deficiency
  • Depression and anxiety
  • Loss of consciousness
  • Nausea and vomiting (9)
  1. Thyroid malfunctioning: Sudden memory loss could also be an indication of thyroid malfunctioning. The thyroid hormones are vital for the functioning of the central nervous system, which includes intelligence, memory, and cognitive behaviors. Studies found that hypothyroidism might affect the memory retaining ability. Other signs of thyroid malfunctioning include:
  • Panic attacks
  • Depression
  • Attention deficiency
  • Weight gain (10)
  1. Sleeplessness: Both human and animal studies found that sleep helps in the formation of long-term memories. Studies also found that sleep deprivation damages the signaling pathways in the hippocampus, which can lead to memory impairment (11).

So, if your teenager is neglecting sleep and has short-term memory loss, then you may connect these two. Other symptoms of sleep deprivation include:

  • Yawning
  • Fatigue
  • Irritability
  • Increased appetite
  • Difficulty in concentration
  1. Depression: Studies that examined neurocognitive functioning in adults with depression, found a link between depression and impairment of executive function, short-term memory, and attention (12). Depression in teenagers could happen due to various reasons such as medical conditions, the stress in daily life, substance abuse, and the start of menstruation in girls (13).
  1. Brain tumors: Memory loss could be one of the many symptoms of brain tumors. Other symptoms include:
  • Severe headaches
  • Seizures
  • Vomiting and dizziness
  • Behavioral changes
  • Speech problems
  • Progressive paralysis of one side of the body (14).

A diagnosis by a medical practitioner is essential to determine the actual cause of memory loss in teenagers.

Diagnosis Of Short-Term Memory Loss

Your child’s doctor would diagnose short-term memory loss through a series of examinations and tests.

Initially, the doctor might ask questions related to

  • Any recent injuries or infections
  • Sleep patterns
  • General mental health
  • Substance abuse
  • Medications
  • Diet and general lifestyle

Laboratory tests may be prescribed to detect any deficiencies or infections. A brain X-ray or CT scan might be done if the doctor sees the necessity.

A few tests that check your child’s cognitive abilities could also give vital information about the cause of memory loss.

Such tests include:

  • Simple spelling and math tasks
  • Basic questions about the date, month, and year
  • Tests that gauge the child’s problem-solving abilities
  • Questions regarding recent events

Treatment For Short-Term Memory Loss

The treatment depends on the cause of memory loss, which your doctor would determine and prescribe based on the diagnosis.

  • Prescribing alternative medications that might have fewer side effects on the nervous system
  • Rehabilitation in the case of substance abuse
  • Surgery or chemotherapy for brain tumors
  • Counseling and behavioral therapies for depression and anxiety
  • Medications and supplements in the case of thyroid and vitamin B12 disturbances
  • Closely monitoring the head injury and surgery if necessary
  • Monitoring and limiting their screen time and smartphone usage

If the memory loss is due to poor concentration, you may try some remedies to improve your teen’s focus.

Home Remedies To Improve Memory In Teens

Following your doctor’s advice is the best treatment for short-term memory loss. If the underlying cause is treated, your child might get their normal memory capabilities back. To help your child during the treatment, you may consider trying a few home remedies to improve concentration.

  1. Chewing gum: A study on schoolchildren in Germany stated that chewing gum improved performance during tests. Another study at a dental school in New York found that chewing gum resulted in better performance in written examinations, but not in practical exams.

Studies stated that chewing gum leads to an increase in alertness and concentration, which could be the reason behind the better performance. However, this will not treat or address short term memory tasks (15). It may only enhance your child’s concentration.

  1. Yoga and meditation: According to a paper published in the European Journal of Physical Education and Sport, yoga, meditation, and breathing exercises might have the following benefits:
  • Combined yoga exercises could help in improving the memory, which could increase the academic performance in teenagers.
  •  Meditation might help attain a higher level of concentration and consciousness.
  • Breathing exercises might help in reducing stress and promote better mental health (16).

Encourage your child to practice yoga and meditation regularly, because the above results would be possible with consistent, long-term practice.

  1. Hard-to-read formatting: Studies found that it takes more concentration and focus to read something that is presented in a difficult-to-read format. Such high levels of concentration might help the child to remember better (17).

Encourage your children to change the font of their study material and practice reading. You may also print instructions and directions in a difficult format so that it could help them remember better.

  1. Doodling: Though this is considered a sign of inattentiveness, research says that doodling might help the brain to concentrate and recall the information better. It could also help in relieving stress and improving focus.

Introduce the art of doodling and encourage them to follow it while reading or recalling information. However, remember to keep a cap on the amount of time they spend doing this (18).

  1. Laughing: Dr. Mark Reeves, a surgical oncologist at the Loma Linda Health University, California, says that stress increases the production of cortisol hormone, and excess amounts of this hormone might damage the neurons involving learning and memory. According to Dr. Reeves, laughter helps in decreasing the cortisol levels, which might help improve short-term memory (19).

Encourage your children to laugh and be happy. Let them indulge in activities that can help them relax and have a good laugh.

  1. Short-term memory loss in teenagers could be reversed when identified in time. Do not blame or shout if your teenager is displaying signs of memory loss. Instead, sit with them and try to understand the root cause. As a parent, it is your responsibility to make sure your teenager does not get scared of not being able to remember or recollect and is assured there is help at hand when they need it.
