What does this new study say?

A new study conducted in the United Kingdom suggests that people diagnosed with ADHD may have a significantly shorter lifespan than those without the condition.

Simply put, according to this study:

  • The lifespan of a male with ADHD can be reduced by about 7 years .
  • A woman with ADHD can have a life expectancy reduced by about 9 years .

But this is not a fixed value. There is some uncertainty in this. That is, for men, this decrease could be between 4.5 and 9 years, and for women, it could be between 6.5 and 11 years.

A professor who conducted this study says, "It is truly sad that some adults with ADHD live shorter lives than they were meant to. People with ADHD have a lot of potential, and with the right support and treatment, they can be successful in life. But often they don't get that support, and they are more likely to be socially isolated and experience stressful events. This negatively affects their health."

What is ADHD? Does it also occur in adults?

ADHD, or Attention Deficit Hyperactivity Disorder, is a condition related to the development of the brain's neurons. Although the exact cause is not yet known, experts believe that genetic influences, environmental factors, and certain problems during the development of the central nervous system may contribute to it.

Many people think that this is something that is limited to childhood. But that is not true. If not identified or treated in childhood, this condition can persist into adulthood. When an adult has ADHD, they can show a variety of symptoms.

Common symptoms of adult ADHD How to see it in practice
Lack of patience When you're in a queue or in traffic, you get angry and tense quickly.
Disorganization It's hard to stay organized, things are always lost, and I forget where I put them.
Weaknesses in time management Always late, procrastinating, and unable to finish work on time.
Difficulty focusing on one thing Even when I start a task, I quickly get distracted and my mind wanders easily.
Restlessness/inability to sit still It's hard to sit in one place, I'm constantly fidgeting and fidgeting.
Mood swings You become happy all of a sudden, sad a little later, or angry quickly.
Difficulty coping with stress I get very anxious over even the smallest problem, and it's hard to handle the pressure.

Why can having ADHD affect lifespan?

Now you may be wondering how stress can affect your lifespan. There are several reasons for this.

The first is underdiagnosis . This study itself says that only one in nine people with ADHD are correctly diagnosed during their lifetime. That means a large number of people live without even knowing they have the condition.

When people don't know exactly what ADHD is, they may resort to the wrong ways to "self-manage" the stress, anxiety, and lack of focus that it causes.

What are these wrong methods?

  • Addiction to drugs and alcohol.
  • Turning to smoking.
  • Taking unnecessary risks (e.g., reckless driving).
  • Unhealthy eating patterns.

These things directly affect physical health. ADHD also causes challenges in education and employment. When all of this is combined, a person's mental and physical health deteriorates. The main reason for the decrease in life expectancy, according to the study, is these risky behaviors and the health problems that arise from them.

So what should we do?

If you're feeling scared after reading this article, don't worry. The purpose of this study is not to scare us, but to educate us. This doesn't mean that everyone with ADHD will die soon. This is about the risks that can arise if left untreated .

The most important thing is, if you suspect that you or someone you know has any of the symptoms mentioned above, don't try to diagnose yourself online. The best thing to do is to see your family doctor (physician) and talk about it.

After a correct diagnosis, there are many ways to manage ADHD.

  • Behavioral therapy
  • Counseling
  • Medications prescribed by the doctor, if necessary
  • Lifestyle changes (exercise, healthy diet, good sleep)

With the right support and treatment, someone with ADHD can live a completely normal, healthy, and successful life. So the best thing we can do is be aware of the risks that studies like this show and seek medical advice if necessary.
