痴呆并非不治之症
Dementia not inevitable

翻译原文：

Dementiamay be avoidable and even reversible, so it's time Australians embraced a positive new attitude to combating the condition, brain experts have urged.
In a hard-hitting report, three of the country's leading research institutes say there is growing evidence the healthy, ageing and impairedbrain can renew cells and reconfigure itself.
Emerging studies suggest diet, exercise, learning, socialising and drugs can actually prevent Alzheimer's disease and other forms of dementia, or at least delay the onset, specialists claim in an international medical journal.
While this is controversial and still speculative, there are also indications these practices can even slow down disease progression, says lead author David Burke, a neurologist at St Vincent's Hospital in Sydney.
"There's been a historical tendency for general negativity about dementia and what can be done about it, but that's now out of step with the science," Dr Burke said.
"We suggest that it's time doctors, patients and the public in general adopt a cautious new optimism that we actually can do something to combat it."
