Gaming and Internet Addiction in Teenagers: Signs and Treatment
ByEl Massar Center medical team
Published:
Gaming disorder means a teenager has lost control over gaming, puts it ahead of school, sleep and relationships, and carries on despite harm for around a year. Falling grades, disrupted sleep and rage when stopped call for an assessment. Treatment is outpatient: CBT, family therapy and care for any underlying condition.
Is gaming addiction a real illness?
Yes, but with precise conditions. The World Health Organization included gaming disorder in the ICD-11 classification among disorders due to addictive behaviours, with three criteria that must all be present:
Impaired control over gaming: over when it starts and stops, how long and how often, so the teenager cannot stop even when they decide to.
Increasing priority given to gaming: so it comes before school, sleep, food, friends, family and activities they used to enjoy.
Continuation or escalation despite negative consequences: despite falling grades, family conflict and obvious exhaustion.
The pattern must be severe enough to cause clear impairment in personal, family or school life, and normally present for twelve months, although the period can be shorter when symptoms are severe. Internet and social-media addiction more broadly has no separate official diagnosis yet, but it is assessed and treated on the same principles.
This means a teenager who plays for long hours in the holidays and then returns to school and friends is not ill, and that the judgement rests on loss of control and harm, not on hours alone.
Signs families notice
Teenagers rarely ask for help themselves; it is the family who picks up the signals. Watch for a change in pattern, not a single moment:
At school: a sudden drop in grades, sleeping in class, lateness or absence, neglected homework.
In sleep: staying up until dawn, a reversed sleep schedule, constant tiredness and headaches.
In mood: irritability and intense anger when the internet is cut or they are asked to stop, obvious anxiety away from the device, mood swings.
In relationships: withdrawal from real-life friends and family activities, preferring relationships inside the game.
In behaviour: lying about playing time, playing secretly at night, and spending money on in-game purchases, sometimes without permission.
In the body: neglected hygiene and eating, weight gain or loss, and neck, wrist and eye pain.
What happens in the brain, and why teenagers are more vulnerable
Modern games and apps are designed to keep users engaged as long as possible: variable, unpredictable rewards, endless levels, loot boxes, notifications and social competition. These mechanisms activate the brain's reward circuit in the same way other addictive agents do, though less intensely than drugs.
Teenagers are more vulnerable for two reasons: a brain whose frontal lobe, responsible for impulse control and planning, is still developing until the mid-twenties, and the psychological needs of this age for belonging, achievement and escape from pressure, which games satisfy quickly and easily in a way real life sometimes does not.
Links with other conditions: anxiety, ADHD and depression
One of the most important things a specialist assessment reveals is that excessive gaming is often a symptom of another problem rather than the problem itself:
Attention deficit hyperactivity disorder: a teenager who cannot concentrate on schoolwork finds that fast-paced games satisfy their brain, so they look “addicted” when the root is undiagnosed ADHD.
Social anxiety: the virtual world feels safer to someone who fears real interaction, so gaming becomes an escape from anxiety rather than a pleasure in itself.
Depression: all-night gaming can be an attempt to numb sadness and emptiness, and it deepens depression by depriving the teenager of sleep, daylight and movement.
Bullying and family problems: retreating into the screen can be a reaction to a painful environment at school or at home.
This is why treating the gaming without treating what lies beneath usually fails, the same dual diagnosis principle we apply to substance addiction.
Before seeing a specialist, the family can gather calm observations that help the assessment:
Record actual gaming hours for two weeks, including the phone, without confrontation.
Notice what happens when stopping is enforced: ordinary annoyance, or a meltdown and anger out of proportion to the situation?
Ask yourselves: have they given up activities they loved? Have school and relationships genuinely suffered?
Talk to the school about concentration, performance and relationships with classmates.
Pay attention to their mood away from the screen: are they sad, anxious or isolated to begin with?
If loss of control combines with clear harm over several months, or signs of depression or self-harm appear, a specialist assessment should not be delayed.
The treatment plan: it starts in the outpatient clinics
Unlike substance addiction, gaming disorder needs no detox, and the great majority of cases are treated without a residential stay. At El Massar Center the path starts in the Outpatient Clinics and includes:
A full psychological assessment
Interviews with the teenager and the family, validated scales for gaming disorder, and screening for attention, anxiety and mood disorders, to establish whether gaming is the problem or the mask.
Cognitive behavioural therapy
The best-supported approach for these cases: identifying the triggers behind compulsive play, challenging thoughts such as “I will never be able to stop”, building time-management and emotional-regulation skills, and setting realistic goals for use rather than a total ban, which usually fails with teenagers.
Family therapy
Because the daily battle over the device damages the relationship and feeds the behaviour, Family Counselling sessions help parents move from watchdog to ally: clear, agreed rules, consistent consequences without shouting, alternative family time, and a good example in their own screen use.
A structured daily routine
Fixed sleep and wake times, daily physical activity, screen-free zones and times such as the bedroom and mealtimes, and real alternatives for achievement and belonging: team sport, a hobby or volunteering.
Treating co-occurring conditions
If the assessment reveals ADHD, anxiety or depression, the psychiatrist sets out a plan of psychotherapy and sometimes medication within the Center's Mental Health Services. Excessive gaming often subsides on its own once the underlying problem is treated.
A residential stay is reserved for the rare cases accompanied by severe depression, a risk of self-harm or a complete collapse in functioning that does not respond to outpatient treatment.
What parents should do, and what to avoid
Do: start with curiosity, not accusation: ask about the game, what they love about it and who they play with.
Do: set the rules with them rather than against them, tie gaming time to completed responsibilities, and be consistent.
Do: protect sleep first; getting devices out of the bedroom at night is the single most important step.
Avoid: sudden confiscation, harsh punishment and humiliation; they increase defiance and lying and can push towards risky behaviour.
Avoid: calling the teenager an “addict” in front of others, or comparing them with siblings.
Avoid: giving up with “the whole generation is like this”; early intervention is far easier.
Key takeaways
Gaming disorder is a recognised ICD-11 diagnosis defined by loss of control, priority over life and continuation despite harm for around a year, not by hours alone.
The key signs are falling grades, a reversed sleep pattern, rage when stopped and withdrawal from real-life relationships.
Excessive gaming often hides ADHD, anxiety or depression that must be treated first.
Treatment is outpatient, with CBT, family therapy and a structured routine; a residential stay is rarely needed.
Parents are decisive: firm rules without violence, regular sleep, real alternatives and seeking help early.
How many hours of gaming a day means my child is addicted?
There is no cut-off number. The ICD-11 diagnosis does not rest on hours but on three things: loss of control over gaming, putting it ahead of school, sleep and relationships, and continuing despite clear harm for around a year. A teenager who plays three hours but lies, stays up all night and whose grades are falling is closer to the disorder than one who plays more in the holidays and then returns to normal life.
Is confiscating the phone and devices the answer?
Sudden confiscation increases anger and lying and destroys trust, and it rarely works in the long run. Clear rules the teenager helps set, consistent consequences without shouting, devices out of the bedroom at night and real alternatives for their time work better. If rules have turned into a daily war, Family Counselling sessions help break the cycle.
How is gaming addiction linked to ADHD?
Closely. A teenager with ADHD struggles to focus on schoolwork while fast-paced games give constant stimulation, so excessive gaming looks like “addiction” when the root is an undiagnosed attention disorder. That is why assessment in our Mental Health Services screens for attention, anxiety and depression, and gaming often subsides once the cause is treated.
How long does treatment for gaming addiction take, and does it need a residential stay?
The great majority of cases are treated through the Outpatient Clinics without a stay, with weekly CBT and family-therapy sessions over roughly three to six months, longer when depression or ADHD also needs treatment. A residential stay is reserved for the rare cases involving a risk of self-harm or a complete collapse in functioning.
Benzodiazepine sedatives and sleeping pills such as Xanax, Valium and Rivotril cause physical dependence within weeks, even as prescribed. Stopping abruptly can trigger seizures and delirium, so treatment is a gradual, supervised taper plus care for the anxiety or insomnia that started it.
Bipolar disorder is a chronic mood illness in which episodes of mania or hypomania alternate with depression, and it is often misdiagnosed as depression alone. It is not cured outright, but mood stabilisers, psychotherapy and regular sleep control it well, and most patients live stable, productive lives in treatment.
Depression is a medical illness, not weakness or a lack of faith. It is diagnosed when low mood or loss of interest lasts at least two weeks alongside changes in sleep, energy and concentration. It responds well to psychotherapy, medication or both, and the earlier treatment starts, the better the odds of a full recovery.
Hashish is detectable in urine for about 3 days after a single use, 5 to 7 days with moderate use, 10 to 15 days with daily use, and 30 days or more in heavy long-term users. In blood it shows for hours to two days, in saliva for 24 to 72 hours, and in hair for up to about 90 days, depending mainly on how often you use and your body fat.
