Participants reported feeling more alert and less tired following acute ingestion of caffeine, but feeling less alert in conjunction with chronic exposure to the drug. On the contrary, performance was found to be significantly impaired when caffeine was withdrawn abruptly following habitual use. No evidence was found that caffeine improved performance, either in the context of acute or habitual use. A double-blind placebo-controlled cross-over design with counterbalancing was employed in which all subjects participated in four experimental conditions involving the ingestion of placebo or caffeine 3 times daily for 6 days followed by a 7th (challenge) day of placebo or caffeine ingestion. This study examined objective indices of performance, and self-reported mood, headache, and sleep in 36 healthy male and female habitual caffeine consumers exposed to a pattern of moderate intake. , Australia.ĭespite being the most widely consumed psychoactive substance in the world, there is considerable confusion regarding the effects of caffeine.

Gradual withdrawal can be achieved without withdrawal headache and with complete disappearance of the induced chronic daily headache.Īcute and chronic effects of caffeine on performance, mood, headache, and sleep. Children and adolescents with high daily caffeine consumption in the form of cola drinks may suffer from caffeine-induced daily headache. Patients were encouraged to achieve gradual withdrawal from cola drinks, which led to complete cessation of all headaches in 33 subjects, whereas one boy and two adolescent girls continued to suffer from migraine without aura not frequent enough to justify prophylactic medication. All were heavy cola drinks consumers at least 1.5 L of cola drinks per day (192.88 mg of caffeine daily), and an average of 11 (range 10.5-21) L of cola drinks a week, which amounts to 1414.5 mg of caffeine (range 1350.1-2700.3). The mean age of the subjects was 9.2 years (range 6-18) and mean headache duration was 1.8 years (range 0.6-5). Over a period of 5 years we have encountered, in a tertiary headache clinic in a general hospital, 36 children and adolescents (17 girls and 19 boys) with daily or near-daily headache related to excessive caffeine intake in the form of cola drinks. We report our experience with children and adolescents with daily or near-daily headache and excessive consumption of caffeine in the form of cola drinks.

Withdrawl of ephedrine can cause diffuse cerebral vasodilation with co-responding hypotension which could also cause headaches from low BP ie. It is structurally related to serotonin and is a 5HT1 agonist with vasoconstrictive properties.It has a selective but heterogenous effect on the carotoid arterial system. Sumitriptan is used to treat migraine and vascular headaches. It's vaso-constrictive properties are diffuse. I have a couple of theories.Įphedrine is a potent vasoconstrictor with corresponding increases in the catecholmines(adrenaline and noradrenaline) inducing a state of hypertension with co-responding high blood pressure.
