Caffeine Consumption Could Treat Some ADHD Symptoms

A team of experts at the UOC has studied the possibility of including caffeine in the therapeutic arsenal used to alleviate some of the symptoms of ADHD.

A systematic review of pre-clinical studies carried out in animal models has concluded that regular caffeine consumption can increase attention and retention capacity in adolescents and adults diagnosed with Attention Deficit Hyperactivity Disorder.

Attention Deficit Hyperactivity Disorder, or ADHD, is a psychiatric pathology for which diagnosis has increased exponentially over the last 20 years. In fact, current estimates suggest that this disorder affects between 2% and 5% of children in Spain, an average of one or two children per classroom, and up to 4% of the adult population.

Despite these high incidence rates, controversy surrounds the treatment of this pathology and the therapeutic approach to it. This varies widely depending on each patient, the symptoms they present and their intensity. For this reason, experts are continuing to investigate different components and substances that may be capable of providing new treatment opportunities for patients diagnosed with ADHD.

A group of experts from the UOC is studying the possibility of using caffeine as part of the therapeutic arsenal to alleviate some of the symptoms of ADHD, given the controversy surrounding the use of some types of medication.

A team of experts at the Universitat Oberta de Catalunya (UOC), coordinated by Diego Redolar, a member of the UOC Faculty of Psychology and Educational Sciences who specializes in neuroscience and researches with the Cognitive NeuroLab group of the UOC Faculty of Health Sciences, has studied the possibility of including caffeine in the therapeutic arsenal used to alleviate some of the symptoms of ADHD, given the controversy surrounding the use of some medicines derived from methylphenidate, among others. The study, a systematic review of animal studies published in open access in the scientific journal Nutrients, concludes that a prescribed consumption of caffeine can increase attention and retention capacity in adolescents and adults suffering from this psychiatric disorder.

“The therapeutic arsenal for alleviating ADHD is limited, and there is a certain degree of controversy around the use of some types of medications and stimulants, especially during childhood and adolescence. That’s why it’s useful to study the efficacy of other substances, such as caffeine,” explained Javier Vázquez, one of the main authors of this paper who is also a researcher in the Cognitive NeuroLab group.

Improved cognitive procedures

According to the authors, this is the first systematic review that has been carried out, including at the cellular level, with results linking caffeine consumption in different animal models of ADHD with an increased attention span, improved concentration, learning benefits, and improvements in some types of memory.

ADHD is a psychiatric pathology estimated to affect between 2% and 5% of the child population.

“This substance improves these types of cognitive procedures, and increases capacity and flexibility in both spatial attention and selective attention, as well as in working memory and short-term memory,” emphasized Vazquez, who added that controlled treatment with this substance “doesn’t alter blood pressure, and doesn’t lead to an increase or reduction in body weight.”

Nevertheless, the researchers point out that caffeine can be a therapeutic tool for this type of symptom, but the results for other characteristic symptoms of ADHD, such as hyperactivity and impulsivity, are not clear. “The results are very positive, but we must be much more careful when prescribing a caffeine-based medical treatment for these symptoms. In diagnoses in which the problem is purely attentional, caffeine may be an appropriate therapy, but if there’s a symptomatological presence of hyperactivity or impulsivity, we must be more cautious,” said the expert.

These benefits therefore clearly indicate that caffeine may be a therapy indicated for the treatment of ADHD. “Our results reinforce the hypothesis that the cognitive effects of caffeine found in animal models can be translated and applied in the treatment of ADHD in people, especially at young ages such as adolescence,” the authors concluded.

Prevalence of diagnosis in ADHD

ADHD is a mental disorder with a diagnosis that has increased exponentially in the last 25 years, especially among children. However, it is hardly prevalent in adulthood. “ADHD isn’t properly diagnosed in adults, although there’s a great deal of diagnosis among children and juveniles,” said Vázquez.

The prevalence of this disorder in adults is very low due to the lack of diagnoses.

As it is a highly infantile or juvenile pathology, treatments that require an intense level of medication to alleviate the symptoms of ADHD are therefore subject to considerable controversy, both among many families and in some areas of medicine.

“We want to emphasize that we aren’t against medication for ADHD, but we’re open to investigating all possible alternatives for improving this type of disorder, and for being able to use caffeine from a therapeutic point of view with all the appropriate medical supervision, a prescribed treatment and follow-up,” said Vázquez.

The study has been published in a scientific journal with a high impact factor and considerable influence in the sector, which is a boost for the entire UOC group. “Being published in Nutrients has been a challenge for the team, due to the journal’s high-quality standards. We’re very proud and satisfied, and it encourages us to continue working in this area in order to improve the treatment of ADHD and reduce its impact on the population,” Vazquez concluded.

    It’s Déjà Vu All Over Again! Sixty (60) years ago much of my food tasted like coffee because my mother had read that caffeine was good for calming hyperactive children. But I don’t believe it had any effect on me.

    Douglas Furtek is right, this is old news.

  3. This is the first time I’m hearing of this! When I was a child (surely I would have been diagnosed with ADHD, if then were now) a butt whipping fixed my undiagnosed ADHD because I would think of whether whatever it was I was about to do, was worth getting spanked for BEFORE I acted. Now that it’s illegal to spank, hyper children just get diagnosed with ADHD, given meds and sent home because teachers & parent’s can’t control their kids otherwise. Kids also grow up without understanding consequences for bad actions/choices. I have a child diagnosed with ADHD as well. He is on meds, but the meds make him angry when they wear off. I’m going to try the caffeine thing since we never let him have it, so it’s something we haven’t tried. Caffeine is still considered a drug, but I’m sure it would be way better than the schedule II controlled substance – that is basically the legalized, pharmaceutical, controlled version of methamphetamine, in chewable pill form – that he is currently prescribed and taking at the moment. I still think a good butt spanking does better justice than any big pharma remedies which only mask the problem, not correct it nor does it teach valuable lessons in the process.

  4. Retired SPED teacher here. This is old news. Research would show that a child would need to consume about a pot full to cause any changes. The poor child would spend all day in the restroom! And what teacher is going to serve coffee in class?
