Drug 'can reverse Alzheimer's symptoms in minutes'| News | This is London
A drug used for arthritis can reverse the symptoms of Alzheimer's "in minutes".
It appears to tackle one of the main features of the disease - inflammation in the brain.
The drug, called Enbrel, is injected into the spine where it blocks a chemical responsible for damaging the brain and other organs.
A pilot study carried out by U.S. researchers found one patient had his symptoms reversed "in minutes".
Other patients have shown some improvements in symptoms such as forgetfulness and confusion after weekly injections over six months.
The study of 15 patients with moderate to severe Alzheimer's has just been published in the Journal of Neuroinflammation by online publishers Biomed Central.
The experiment showed that Enbrel can deactivate TNF (tumour necrosis factor) - a chemical in the fluid surrounding the brain that is found in Alzheimer's sufferers.
When used by arthritis sufferers, the drug is self-administered by injection and researchers had to develop a way of injecting it into the spine to affect the brain cells.
Sue Griffin, a researcher at the University of Arkansas for Medical Sciences, said: 'It is unprecedented to see cognitive and behavioural improvement in a patient with established dementia within minutes of therapeutic intervention.
'This gives all of us in Alzheimer research a tremendous new clue
about new avenues of research.' Enbrel is not approved for treating Alzheimer's in the U.S. or the UK and is regarded as highly experimental, said Dr Griffin.
'Even though this report predominantly discusses a single patient it is of significant scientific interest because of the potential insight it may give into the processes involved in the brain dysfunction of Alzheimer's,' she added.
Lead author of the study Edward Tobinick, of the University of California and Director of the Institute for Neurological Research, said the drug had 'a very rapid effect that's never been reported in a human being before'.
