A Drug Than Can Cure Fear in Human Beings

MIT Researchers are on their way to test the first drug to treat the millions of adults who suffer each year from persistent, debilitating fears - including hundreds of soldiers returning from conflict in Iraq and Afghanistan.

Emotional disorders such as post-traumatic stress and panic attacks stem from the inability of the brain to stop experiencing the fear associated with a specific incident or series of incidents.

Inhibiting a kinase, an enzyme that change proteins, called Cdk5 facilitates the extinction of fear learned in a particular context. Link.
