The first six paragraphs.
MEDICAL regulators have warned the public to be wary of a new private stroke-screening service, saying they could be wasting their money as there is little evidence the tests can reduce risk of the condition.
International preventive health company Screen for Life has recently started operating in Australia and is mailing over-50s, urging them to make an appointment for a $199 stroke screen.
The test involves an ultrasound of the neck to check for hardening of the carotid arteries - blood vessels that supply blood to the brain - which can cause stroke.
''As you age, fatty deposits known as plaque can build up in your arteries. You may not notice any symptoms but the silent danger is there,'' the Screen for Life letter reads.
Health experts say this could lead to unnecessary invasive procedures, as many people have some degree of hardening of the arteries but are not at risk of stroke.
The National Stroke Foundation has distanced itself from the group, posting a warning on its website saying that it does not endorse Screen for Life's services nor does it support medical tests that may be unnecessary.
