"Brain Rot": Are TikTok, Reels and Short-Form Videos Really Changing Our Attention?

You open TikTok or Instagram "just for five minutes". One video lasts 20 seconds, another 15. The third makes you laugh, the fourth surprises you, and by the fifth you have already forgotten what the first one was about.

The next time you look at the clock, half an hour has passed.

Then you try to read a few pages of a book, finish a long article, or watch a film without reaching for your phone - and suddenly, sustaining your attention feels considerably more difficult.

In recent years, the term "brain rot" has increasingly been used to describe this subjective experience.

But are TikTok, Instagram Reels and YouTube Shorts genuinely "damaging" our brains? Or is "brain rot" simply another popular expression that oversimplifies a much more complex phenomenon?

From a psychiatric perspective, the answer lies somewhere in between. "Brain rot" is not a medical diagnosis, nor does it mean that the brain is literally deteriorating. However, the way we consume short-form digital content may be associated with changes in how we allocate attention, control impulses and tolerate boredom.

What Does "Brain Rot" Actually Mean?

The term "brain rot" is commonly used online to describe a sense of mental overstimulation, fragmented attention and increasing difficulty remaining engaged with activities that require sustained concentration.

People may notice that they:

  • automatically reach for their phone whenever there is a brief moment of inactivity;
  • struggle to watch a film or television programme without simultaneously checking their phone;
  • increasingly skim written material rather than reading it attentively;
  • rapidly lose interest in content that does not provide immediate stimulation;
  • feel a constant urge to switch from one piece of content to another;
  • find boredom or the absence of stimulation increasingly uncomfortable.

Although the term sounds dramatic, "brain rot" is not a recognised psychiatric or neurological disorder. Problematic consumption of short-form video content is likewise not classified as a distinct diagnosis in either the DSM-5 or ICD-11.

Nevertheless, the phenomenon the term attempts to describe has increasingly attracted scientific attention.

Why Are TikTok, Reels and Shorts So Compelling to the Brain?

Short-form video platforms combine several psychologically powerful features: novelty, speed, emotionally salient information, personalised algorithms and an almost limitless supply of new content.

Every swipe offers something different.

We do not know whether the next video will be boring, amusing, shocking, emotionally engaging or exceptionally relevant to us. This unpredictability can reinforce repeated engagement.

This is why it is overly simplistic to say that we are merely "addicted to dopamine".

Dopamine is not simply a "pleasure chemical" that becomes depleted because we spend too much time on TikTok, as is sometimes suggested on social media. It is a neurotransmitter involved in multiple processes, including motivation, learning, reward prediction and the regulation of goal-directed behaviour.

The more relevant issue is that we may become accustomed to an environment in which novel stimulation is available almost instantly and with virtually no effort.

Do Short-Form Videos Really Affect Attention?

Current research provides reasons for caution, but not for panic.

A large systematic review and meta-analysis involving 71 studies and 98,299 participants found that greater short-form video use was associated with poorer cognitive functioning. The strongest associations were observed in attention and inhibitory control.

In practical terms, individuals who engage more intensively with short-form video content tend, on average, to demonstrate greater difficulties sustaining attention and inhibiting automatic responses.

Other systematic reviews have also reported associations between problematic short-video use and difficulties involving executive functions, self-control and working memory, particularly among adolescents and young adults.

However, one distinction is essential:

Correlation is not causation.

We cannot simply conclude:

"TikTok damaged their attention."

It is equally plausible that individuals who already have greater impulsivity, poorer attentional control or a lower tolerance for boredom are more likely to engage intensively with short-form digital content.

The relationship is probably complex and bidirectional, involving individual characteristics, patterns of platform use and the design of the digital environment itself.

High-quality longitudinal research is therefore still needed to establish how these relationships develop over time.

Attention Is Not a Muscle That Simply "Breaks"

Human attention is not a single cognitive function.

Several processes allow us to direct attention, sustain concentration, ignore irrelevant stimuli, shift focus when necessary and inhibit the impulse to respond to every new piece of information.

Particularly important are our executive functions, the cognitive processes involved in planning, self-regulation, impulse inhibition and goal-directed behaviour.

Spending an hour switching between videos every few seconds creates a fundamentally different cognitive environment from spending an hour reading a book.

In the first situation, the content is continuously competing to capture and retain our attention.

In the second, we are responsible for sustaining attention ourselves.

That distinction matters.

Why Can Longer Content Feel "Too Slow" After Short-Form Videos?

A book does not change the subject every 15 seconds.

A lecture does not immediately provide a new visual stimulus whenever we become bored.

A conversation does not have a "skip" button.

And everyday life rarely offers instant rewards.

If a substantial proportion of our leisure time is spent in digital environments characterised by rapid novelty and frequent stimulation, slower activities may gradually begin to feel subjectively less engaging.

This does not necessarily mean that we have lost the ability to concentrate.

Rather, we may have developed a habit of relying on continuous external stimulation to maintain attention, instead of actively sustaining it ourselves.

We Have Become Increasingly Uncomfortable With Boredom

Waiting for the lift - phone.

Standing in a queue - phone.

Travelling on public transport - phone.

Waiting a few minutes for a friend - phone.

Even while watching television, many people simultaneously use a second screen.

As a result, the small periods of the day in which the brain has no immediate external task are gradually disappearing.

Yet boredom is not necessarily an enemy.

Periods of low stimulation can provide space for reflection, spontaneous thought, planning and mental rest.

If every moment without stimulation is automatically filled with new digital content, we may gradually become less tolerant of situations in which "nothing is happening".

Does TikTok Cause ADHD?

No.

TikTok, Instagram Reels and YouTube Shorts cannot simply be regarded as causes of ADHD.

ADHD is a neurodevelopmental disorder with complex genetic and neurobiological foundations, and its symptoms emerge during development.

However, intensive or problematic digital-media use can produce patterns of behaviour that superficially resemble certain ADHD symptoms: fragmented attention, frequent switching between activities, difficulty delaying gratification, compulsive phone checking and difficulty persisting with monotonous tasks.

It would therefore be misleading to conclude:

"I can no longer watch a two-hour film, so I must have ADHD."

An ADHD diagnosis requires a considerably broader assessment of symptoms, developmental history and functioning across different areas of life.

When Does Short-Form Content Become a Problem?

The number of minutes spent on social media is not the only relevant factor.

A more important question is:

Is the way I use these platforms beginning to interfere with my everyday functioning?

It may be worth paying attention if you repeatedly try to reduce your use but cannot, remain online considerably longer than intended, delay sleep because of scrolling, struggle to complete tasks without checking your phone, or experience significant discomfort when you cannot access digital content.

An especially important shift occurs when short-form content stops being merely entertainment and becomes a primary strategy for regulating uncomfortable emotions.

I am bored - I scroll.

I am anxious - I scroll.

I feel lonely - I scroll.

I do not want to think about a problem - I scroll.

At that point, the phone may begin to function as a form of avoidance rather than simply a source of entertainment.

Do We Need to Stop Using TikTok and Reels Completely?

For most people, no.

The central issue is not necessarily the existence of short-form content itself, but the loss of control over how we engage with it.

The goal therefore does not need to be a complete "digital detox" or total withdrawal from social media.

A more realistic approach is to regain deliberate control over attention.

This can begin with relatively simple changes: disabling unnecessary notifications, keeping the phone out of immediate reach while working, allocating specific periods for social media rather than opening apps automatically, and avoiding prolonged scrolling immediately before sleep.

At the same time, it can be helpful to deliberately reintroduce activities that require sustained attention: reading, having a longer conversation without checking your phone, watching a film without using a second screen, exercising, studying, or simply going for a walk without constant digital stimulation.

Concentration may not improve overnight. But attention is a dynamic cognitive system, and our everyday habits matter.

Try a Simple Experiment

The next time you feel the urge to open TikTok or Instagram without a specific reason, do not immediately forbid yourself from doing so.

Instead, pause for a few seconds and ask:

"Why am I reaching for my phone right now?"

Do I genuinely want to watch something?

Am I bored?

Am I avoiding a task?

Am I anxious?

Was reaching for my phone completely automatic?

Simply recognising the automatic nature of the behaviour creates an important distinction between a conscious choice and a habit.

"Brain Rot" Probably Is Not Your Brain Rotting - But It Raises an Important Question About Attention

The term is dramatic and scientifically imprecise. Your brain does not literally "rot" because you watch Instagram Reels or TikTok.

However, the question behind the expression is legitimate.

The modern digital environment exposes us to an unprecedented volume of rapid, personalised and virtually continuous stimulation. Emerging research increasingly demonstrates associations between intensive or problematic short-form video consumption and attention, inhibitory control and other executive functions.

At the same time, we still do not have sufficient evidence to claim that several years of TikTok use permanently changes or "damages" the brain.

Perhaps, then, instead of asking:

"Is TikTok destroying my brain?"

we should ask a different question:

"Am I still deciding where my attention goes or is the algorithm increasingly deciding for me?"

In a world in which thousands of pieces of content compete for our attention every day, the ability to consciously direct and sustain that attention may be becoming one of the most important skills for protecting our mental well-being.

When Should You Speak to a Professional?

If difficulties with concentration, compulsive phone use, sleep disturbance, anxiety or declining everyday functioning become persistent or pronounced, it may be useful to consider the broader clinical picture.

Problems with attention are not necessarily caused by social media. They may also be associated with chronic stress, anxiety disorders, depression, sleep problems, ADHD or other psychological and medical factors.

A professional assessment can help determine what is actually contributing to the symptoms and which approach is likely to be most appropriate.
