ADHD in adults can be life-threatening when left untreated: experts - National | Globalnews.ca (2024)

Chloe was first diagnosed with attention-deficit hyperactivity disorder (ADHD) when she was 19.

The Toronto native, who did not share her full name with Global News, said in her first year of university, her grades were disappointing.

“My parents were confused… and I was concerned,” Chloe, 22, said.

“During [school], I would get so overwhelmed because I wasn’t able to finish readings… I’d get distracted by someone walking by or a noise from a roommate.”

Chloe always thought she might have ADHD, but she dismissed the possibility because “so many people say it as a saying.”

“I’m always moving, and my brain is always on — whether it’s tapping my foot… cracking my knuckles or playing with my hands,” she said.

She was open to seeing a doctor, but Chloe was worried that people would judge her if she had a formal diagnosis.

“All my teachers throughout elementary and high school said I was a distraction in class,” she explained.

It wasn’t until she had a formal evaluation that Chloe discovered she had ADHD, along with anxiety and depression. Chloe has since been diagnosed with a personality disorder as well.

The diagnosis wasn’t a shock.

“I believe I’ve had it since I was a child,” she said. “All my report cards talk about my focus and attention span.”

What it feels like to have ADHD

The symptoms aren’t the same for everyone, but ADHD is often debilitating.

“Often, it’s kind of like living in a fog… The way it’s been described to me is like everything almost looks blurry physically,” said Dr. Doron Almagor, a child, adolescent and adult psychiatrist and director of The Possibilities Clinic in Toronto.

“When you have a conversation, you lose track. You’re at work and you forget what you’re doing.”

People with ADHD can also experience issues with their working memory, which means they’ll walk into a room and forget why they’re there.

“Brains with ADHD aren’t working at full capacity,” said Almagor. “That’s why, often, the medications we have for ADHD stimulate the brain to make it active and bring them to normal levels of activity and attention.”

Most people have some or all of these symptoms at some point in their lives, which can make it difficult to know when it’s actually ADHD.

“Nobody has perfect memory… but for [people with ADHD], it’s extreme. They feel like they’re lost all the time,” Almagor said.

He believes this is why people don’t take ADHD seriously.

“I think that’s why some people don’t respect the severity of what [a person with ADHD] can experience,” he said.

Chloe experienced the stigma around ADHD first-hand. She thinks she didn’t receive her diagnosis until she was an adult because her parents and teachers believed her issues were within her control.

“They thought I just had to try harder,” she said.

ADHD still isn’t considered a serious disorder

Stigma is a large barrier to diagnosing ADHD, according to Almagor.

“It’s getting better, but a lot of people resist diagnoses for many years because they’re worried about their kid ‘being labelled.'”

There’s a large cohort of adults only now being formally diagnosed, Almagor explained, and he believes stigma in past generations is to blame. It’s improving, but slowly.

“I’m optimistic and I’ve seen changes… but it moves at a snail’s pace,” said Almagor. “We may be going up by one per cent [in awareness] each year.”

It is estimated that 1.1 million Canadian adults have ADHD, according tothe Centre for ADHD Awareness Canada, and the persistent lack of awareness concerns Almagor.

“When people don’t know about it, [kids] don’t get noticed and it goes undiagnosed,” he said. “A lot of people get missed.”

Unfortunately, any delay in treatment can lead to anxiety and depression — as it did with Chloe.

The underdiagnosis of ADHD disproportionately affects girls and women because the disorder usually affects them differently, he continued. Girls don’t typically display “hyperactive” symptoms, making it less visible.

“Teachers don’t see it, and [these girls] are considered inattentive instead,” said Almagor. In his experience, most adults only realize that they might have ADHD after their child is diagnosed.

Treating adults is more complicated

When a child is suspected to have ADHD, a battery of psychological tests is performed. Parents and teachers are interviewed, and several doctors are involved.

“A lot of information is collected,” said Heidi Bernhardt, president of the Centre for ADHD Awareness Canada. “For a diagnosis to occur, you need to see the symptoms in more than one setting. If we only see it at home or we only see it at school, then we start to question it.”

After the initial research is done, the physician will gather a physical and mental medical history of the child’s family because ADHD is hereditary.

“Then we do a differential diagnosis… to rule out anything else that might be mimicking the symptoms of ADHD,” said Bernhardt. “You want to rule out learning disabilities, anxiety, depression, childhood trauma… all that kind of stuff.”

ADHD commonly coexists with other disorders so the tests need to be extremely thorough in order to determine if ADHD is actually present.

Then doctors will try to determine the severity of the child’s ADHD.

“It’s much more than attention,” she said. “It can be problems with over-focusing as much as under-focusing or switching focus… it’s not a 15-minute doctor’s visit.”

In adults, this process is much more complex. For starters, doctors have access to less information by way of report cards, teachers and parents. Sometimes, all they can do is interview the adult themselves.

“In adults, you have this long history… [and] there’s a higher incidence of coexisting disorders, especially when ADHD wasn’t treated in childhood,” Bernhardt said. “The longer ADHD goes untreated, the greater chance we’re probably looking at coexisting disorders.”

There are more things to tease out, according to Bernhardt. Doctors will often look to significant others or past report cards, if the patient still has them, for any signs that ADHD has long been an issue for the patient.

“Adults with ADHD… aren’t usually the most accurate at quantifying or describing their impairments,” she said. This is because these adults have gone their entire lives with ADHD so they figure it’s “normal,” Bernhardt explained.

“It’s the only reality somebody with ADHD has ever had,” she said. “They don’t see it as an impairment.”

Most adults with ADHD will have struggled their whole lives with school, and sometimes, they have already been treated for anxiety, depression or substance abuse.

More awareness is needed

In order for patients to avoid developing other disorders in adulthood, doctors are focused on catching more diagnoses during childhood.

For that, there needs to be more education and awareness about the trials and tribulations of having ADHD, Almagor says.

“More doctors are being trained in it, for sure, but there’s still a gap,” said Almagor.

The longer ADHD goes untreated, the more a patient is at risk of developing mental health and substance abuse issues.

“People tell me how hard it is or how frustrating it is and how, when they get properly treated, how wonderful it is,” said Almagor.

“I encourage people, if they suspect they have ADHD, that they speak to their family doctor or look otherwise into obtaining diagnosis or treatment from a specialized clinic.”
