In the strange, upside-down world of the Southern Hemisphere, cold and gloomy Winter is quietly slinking away, and raucous Spring in all his glory begins to stir. Ah, Spring! The season of buds and blooms and frolicking wildlife. One rare species of wildlife, however, finds itself subject to an open hunting season this Spring – the anti-vaxxer.
In April this year, the Australian Federal Government announced a so-called “no jab, no pay” policy. Families whose children are not fully vaccinated will now lose subsidies and rebates for childcare worth up to almost AUD$20,000 per child, except if there are valid medical reasons (e.g. allergies). Previously, exemptions had been made for conscientious and religious objectors, but these no longer apply forthwith.
Taking things a step further, the Victorian State Government earlier this week announced an additional “no jab, no play” policy. Children who are not fully vaccinated, except once again for valid medical reasons, will additionally now be barred from preschool facilities such as childcare and kindergartens.
I should, at this point, declare my allegiances – as a finishing medical student, I am utterly convinced by the body of scientific evidence supporting the benefits of childhood vaccination. I am confident that these vaccines, while posing a very, very small risk of severe side-effects like any other medicine, reliably prevent or markedly reduce the risk of contracting equally severe diseases. And finally, I believe that the goal of universal childhood vaccination is one worth pursuing, and is immensely beneficial to public health.
Despite my convictions, however, I still find myself wondering if the increasingly strict vaccination regime in Australia, and every-increasing punishments for anti-vaxxers, is necessarily the best means to go about achieving a worthy goal. It’s not clear, to me, that the recent escalation will have significant positive effects beyond a mere simple political stunt.
“Whoa though, does it ever burn” – Why the consumer market for brain stimulation devices will be a good thing, as long as it is regulated
In many places around the world, there are people connecting electrodes to their heads to electrically stimulate their brains. Their intentions are often to boost various aspect of mental performance for skill development, gaming or just to see what happens. With the emergence of a more accessible market for glossy, well-branded brain stimulation devices it is likely that more and more people will consider trying them out.
Transcranial direct current stimulation (tDCS) is a brain stimulation technique which involves passing a small electrical current between two or more electrodes positioned on the left and right side of the scalp. The current excites the neurons, increasing their spontaneous activity. Although the first whole-unit devices are being marketed primarily for gamers, there is a well-established DIY tDCS community, members of which have been using the principles of tDCS to experiment with home-built devices which they use for purposes ranging from self-treatment of depression to improvement of memory, alertness, motor skills and reaction times.
Until now, non-clinical tDCS has been the preserve of those willing to invest time and nerve into researching which components to buy, how to attach wires to batteries and electrodes to wires, and how best to avoid burnt scalps, headaches, visual disturbances and even passing out. The tDCS Reddit forum currently has 3,763 subscribed readers who swap stories about best techniques, bad experiences and apparent successes. Many seem to be relying on other posters to answer technical questions and to seek reassurance about which side effects are ‘normal’. Worryingly, the answers they receive are often conflicting.
