Sometimes the effect can be negative, however. For example, people who have trouble sleeping can experience further sleep disturbances or insomnia due to caffeine. People with ADHD should only use caffeine in the morning and should avoid consumption of coffee, tea, soda, or chocolate in the evening or late at night.
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.
Dopamine levels in the brain have to be within a very narrow margin in order for a person to be able to focus on their work. But in ADHD, dopamine levels are too low. Stimulant chemicals such as caffeine or amphetamines tend to increase dopamine levels. For most people, adding stimulants will push dopamine levels too high, causing agitation and anxiety.
But for people with ADHD, adding stimulants can get the levels just right. A few cups of coffee throughout the day can make a real difference. Some studies have found that caffeine can boost concentration for people with ADHD.
However, caffeine alone is less effective than prescription medications. Adults can use caffeine safely for their ADHD, but caffeine consumption can actually harm children and teens. When caffeine and amphetamine medications like Adderall amphetamine and dextroamphetamine combine, they cause an effect called synergy. However, clinicians and parents should be alert for the following potential negative effects. Side effects rarely are sufficiently severe to require discontinuation of medications; many are alleviated by changes in time of administration or dosage reduction.
Although minor in most cases, growth should be monitored at least every 3 months early in treatment. Significant decreases in weight gain can often be managed by giving medications with or after meals and by maximizing caloric intake when children are "off" meds e. Sleep disturbances may occur in a small percentage of children, but are typically transient. Sometimes children actually sleep better on treatment, for they can finally "turn off the off-switch and go to sleep.
Growth suppression sufficient to affect height growth as well as weight growth has been reported. This effect appears to be uncommon, may be transient and in many cases seems to subside after years of therapy or when stimulants are discontinued. Switching from one first-line agent to another — from amphetamine, say, to methylphenidate, or vice versa — can be effective. While there is no research-based guidance on how to treat this fairly common problem, practitioners find that taking a low dose of a calcium channel blocker an hour before taking the stimulant prevents headaches from occurring in about 95 percent of people.
For reasons that are unclear, more than half of patients who had severe headaches can stop taking the calcium channel blocker after one or two months without the recurrence of headaches. Talk with your doctor about his treatment for headache relief. William Dodson, M. Was curious because I was just diagnosed with adhd. Thank you Dr. Dodson for this insight and all your work on ADHD. One thought, it is common for people with ADHD to have elevated calcium in the blood according to Dr.
Walsh, so if calcium channel blocker minimizes the headache I wonder if the people who get the headaches might have elevated calcium and there are some studies that connect the two see below.
