International health insurance customers who find themselves plagued by headaches could be glad to learn that a pharmaceutical solution might not be necessary.
According to recent research published in the Journal of Manipulative and Physiological Therapeutics, placebo groups in clinical trials have an average recovery rate of 36 per cent.
Furthermore, control groups in pharmacological trials showed a higher response rate than the behavioural trials ( 38.5 per cent versus 15 per cent).
In response to the results, the authors noted that it is important for doctors to know that a substantial portion of headache patients improve without treatment.
They added: "The prescription of medication needs to be carefully considered and evaluated with each individual patient.
"Because of the recovery results in 'no treatment' control groups in pharmacological trials, the question rises whether or not this way of prescription is always preferable over no treatment."
