The rats took part in a range of learning and memory tests. One of these, for example, involved the rats being placed in a pool of water with a hidden escape platform. At the start of the study, untreated young rats learned to recognise landmarks and quickly find their way to the platform, while the untreated older animals struggled at the task.Yes, it seems Montelukast alleviates the inflammatory effects of Endotoxin.
By the end of their six-week drug regime, though, old animals performed as well as their younger companions. “We’ve restored learning and memory 100 per cent, to a level comparable with youth,” says Aigner. He presented his findings last week at the Society for Neuroscience meetingin Chicago.
When the team studied the brains of the animals, they found that old rats that had been given Montelukast had 80 per cent less inflammation. They also had an enhanced level of new neuron growth compared with untreated old rats – about 50 per cent of that seen in young rats, says Aigner.
The team also found that the blood-brain barrier – which stops infectious agents reaching the brain and which weakens in old age – was stronger in treated old rats. “Structurally, the brain had rejuvenated,” says Aigner.
I think we need to start a campaign to research this. I want some, dammit.
