Anti-obesity drug improves associative learning in people with obesity

Obesity leads to altered energy metabolism and reduced insulin sensitivity of cells. The so-called 'anti-obesity drugs' are increasingly used to treat obesity and have caused tremendous interest, especially in the USA. Researchers have now shown in people with obesity that reduced insulin sensitivity affects learning of sensory associations. A single dose of the anti-obesity drug liraglutide was able to normalize these changes and restore the underlying brain circuit function.
