Reduced Blood Flow To The Brain

The Science Behind Caffeine Metabolism & Why It’s Not Connected to ADHD

Caffeine is also a vasoconstrictor. That means it makes blood vessels smaller and reduces blood flow. This reduced blood flow is why caffeine helps headaches. Amphetamine medications used to treat ADHD also make blood vessels smaller. Caffeine may have some effects similar to those of common ADHD medications.

Although the exact reason is unknown, reduced blood flow may help treat ADHD by reducing the activity of brain regions that are overactive, allowing them to better function and cooperate with the rest of the brain.

Caffeine and ADHD

Caffeine is found in coffee, tea, and chocolate to name a few, and its one of the worlds favorite drugs. But what impact does it have on your brain? The right amount of caffeine can help you focus, but too much might make you jittery, anxious, or irritable.

Because caffeine is so prevalent, its important to know how it affects individuals with ADHD.

What Does The Research Say About Treating Adhd With Caffeine

Researchers studying caffeine in relation to ADHD is nothing new, but the actual body of research remains relatively small and inconclusive.

A 2011 study8 published in the Journal of Medical Hypotheses and Ideas reports tea consumption may prove effective to help treat ADHD in adults. Another study9 that same year found a significant improvement in attention deficit disorder in rats who consumed caffeine.

A 2014 review10 in the journal Psychopharmacol called for further investigation of caffeines therapeutic potential as a therapy or an adjunctive agent in ADHD. And a 2013 study11 published in European Neuropsychopharmacology suggests that caffeine could be useful as a treatment, as it appears to normalize levels of dopamine and improve attention in people with ADHD.

Some People Build A Tolerance To Caffeine

People who regularly consume coffee and other caffeinated beverages can develop a tolerance to it. Since caffeine blocks adenosine receptors, the body produces more adenosine receptors to counteract the effects of frequent caffeine consumption.

In one small study , researchers examined the effects of continuous caffeine consumption on the cycling performance of 11 physically active adults.

At the start of the study, the participants had higher heart rates and exerted greater cycling power after drinking caffeine. After 15 days, however, the effects of the caffeine began to decrease.

Given these results, it appears that people who regularly consume caffeine may build up a tolerance to its stimulant effects.

However, other research has suggested that continuous exposure to caffeine how the body absorbs or metabolizes it.

The second most common reason for coffee not working correctly is the abuse of caffeine in the first place. Drinking coffee has its benefits like getting rid of slumber and sleepiness, energizing the body for a days work. But overconsumption of it can lead to catastrophic consequences. Apart from an increase in heart diseases, youre also likely to lose all sensitivity to caffeine.

Like any other foods and drinks, coffee has its limits, set by the medical experts. Taking in anything above 300-400mg of caffeine will reduce sleep to an alarming rate. Continuous consumption of such a high dosage of coffee each day will limit your bodys sensitivity towards the substance.

Your body will slowly become immune to the effects of caffeine and desire more to recharge up. So, this cycle will continue while you increase the intake every day to get some lift. So, yes, if youre overconsuming it, try to limit and discipline the nature of drinking coffee to maximize the impact.

How Does Caffeine Affect The Brain

Caffeine works by stimulating the brain and nervous system. It does this by blocking the action of a chemical called adenosine. Adenosine is a neurotransmitter that slows down nerve cell activity so it is responsible for making us feel sleepy. When caffeine blocks adenosine, it increases nerve cell activity and makes us feel more awake and alert.

Why Doesnt Caffeine Affect Adhd

Because most ADHD prescriptions are based on stimulants, it may seem okay to try ADHD self-medication with caffeine. Not so fast, gentle reader. Things are not that straightforward. On caffeine and ADHD, it is said that caffeine can have risky effects on children with ADHD and should not be considered.

One study suggests that caffeine may be beneficial as an ADHD treatment because it normalizes dopamine levels and improves attention in people with ADHD.

Another study suggests that tea containing caffeine may help adults with ADHD. Although caffeine is similar to ADHD medications, there are some cautions to consider before using it.

In normal times, adenosine, a molecule whose role is to protect the brain by slowing down nerve activity, regularly attaches itself to small receptors present on neurons to induce a state of drowsiness. However, since caffeine molecules have the same molecular structure, they can bind to these receptors and prevent adenosine from acting.

The action of neurons is accelerated, while this increased activity also leads the pituitary gland to ask the body for increased production of adrenaline, a stress hormone.

But like enzymes, no two people have the same number of receptors. So, for a given quantity of caffeine in the brain, the biological effects will depend on the number of receptors available.

Can You Treat Adhd With Caffeine

I regularly get emails from readers saying:

I have ADHD. I dont want to take medication. Can I take/do_____instead?

They might be suggesting flaxseed oil, a homeopathic remedy, meditating or caffeine.

It would be great if there was ONE thing that resolved all ADHD related problems. There isnt.

Instead, managing ADHD effectively requires a multi-pronged approach education, behavioural changes , lifestyle changes , learning ADHD friendly techniques , possibly therapy, possibly ADHD meds.

Even though caffeine and ADHD medication like Adderall are both stimulants, its not as simple as replacing one thing for another because neither is a complete treatment.

Its easy to see why people think caffeine could be used to replace meds, though, because both are stimulants.

However, while caffeine and stimulant ADHD medication are both central nervous system stimulants, they work differently on the brain.

ADHD meds

ADHD meds increase the amount of neurotransmitters dopamine and norepinephrine in your brain, which means focus and concentration increase.


In contrast, caffeine blocks the neurotransmitter adenosine from taking its usual action of prompting sleep, which means feeling alert, etc.

In his book, Taking Charge of Adult ADHD, Dr. Russell Barkley says caffeine affects the wrong brain neurochemicals for people with ADHD and advises prescription ADHD medication over caffeinated substances.

What Can I Do If I Want To Feel The Effects Of Caffeine

If you want to feel the effects of caffeine, there are a few things you can do.

First, try drinking more of it. If youre only having one cup of coffee in the morning but you cant get feeling, try having two or three. You might also want to try drinking caffeinated beverages throughout the day instead of just in the morning. Or another way, you will reset your caffeine tolerance by trying slowly cutting down on the amount of caffeine you consume or taking a break from it for a few days to a week. Once you restart, you may find that the effects are stronger than before.

Second, try slower-releasing sources of caffeine like tea or chocolate. These can take longer for the body to absorb, so you might feel their effects for longer.


Third, lower your sleep debt. We recommend keeping your sleep debt below five hours. Take a nap for 10 -15 minutes or sleep an extra hour to help reduce your debt. Focus on your sleep. Sleeping a lot will still not be as effective as you sleeping less but having a deep sleep. When you wake up, you will not feel tired and get rid of the dream state. Let your mind relax before going to sleep to achieve results.

Fourth, try to establish a regular sleep schedule. Go to bed and wake up at roughly the same time each day, even on weekends. This will help train your body to fall asleep and wake up at certain times, making it easier to get a good nights sleep.

The Verdict To Why Caffeine Doesnt Affect Me

Being unaffected by caffeine is fairly common and is probably a combination of multiple factors listed here, not just one. After all, its not a miracle cure for sleepiness.

So, if you find yourself questioning why caffeine doesnt affect me and craving the jolt of energy, try looking for alternative ways to perk yourself up.

No matter what your preferred caffeine source is cold brew, espresso, French press, tea, or energy drinks if you are no longer feeling the benefit, try dialing it back a little over time. Then, add back in the occasional extra cup to try and get the much-needed boost.

Youre Experiencing Withdrawal Symptoms

Caffeine Doesn T Affect Me Adhd - (3)

It may sound counterintuitive to be experiencing withdrawal symptoms, while still consuming caffeine, but research shows you donât need to have cut out caffeine altogether to feel withdrawal.

For example, one study found when people who were used to consuming 300 milligrams of caffeine cut down to 200 mg or less, they experienced withdrawal symptoms. And while 100 mg of caffeine sounds like a lot, thatâs equivalent to about one 8-ounce cup of coffee. So, if youâre used to drinking four cups of coffee a day, and you go down to three, this may be the reason why youâre feeling tired â itâs the withdrawal symptoms not the coffee itself. And you may start feeling these symptoms 12 to 24 hours after your last sip of coffee, but it can happen sooner.

Caffeine also triggers adrenaline and the stress hormone cortisol, so without these, youâre left feeling less alert and awake than youâre used to.

Symptoms of caffeine withdrawal includes:

What The Research Says

While some people report benefits from adding caffeine into their daily routine, others dont. If youre contemplating trying caffeine as a way to lessen your ADHD symptoms, it might be helpful to look into the latest research for answers.

One study found that young, hyperactive rodents who received caffeine combined with exercise showed improvements in behavioral performance, serotonin and dopamine levels, and the brains ability to make new connections.

The research team suggested that these results provide new evidence that caffeine in conjunction with exercise starting in adolescence may be a possible treatment option for ADHD.

Other recent research exploring caffeine use in U.S. Army soldiers with ADHD found promising evidence that consuming caffeinated foods and drinks may improve cognitive performance and impulsive behavior.

Researchers said that more research is needed, but preliminary evidence indicates caffeine or other adenosine receptor antagonists may play a role in treating this mental health condition.

Although these studies show some evidence that caffeine works for ADHD symptoms, others reveal something different. For example, research published in Current Developments in Nutrition found that caffeine used alone increased impulsivity in adolescent boys.
