Last week Migraines were good for fending off memory loss in middle age people. Now this week migraines are causing brain damage that potentially can lead to strokes. Pretty fair trade off eh?! Better memory for a horribly disabling stroke that might destroy your memory anyway (well... or kills you)!

Alright... here's the details:

The research, which was done in mice, also suggests giving oxygen may help reduce the damage, said Takahiro Takano, Maiken Nedergaard and colleagues at the University of Rochester in New York, working with a team at the Danish pharmaceutical group Novo Nordisk.

They studied a process called cortical spreading depression, known as CSD, a wave of changes in cells associated with migraine, stroke and head trauma.

They used a precise two-photon microscopic and oxygen sensor microelectrodes to look at the brains of live mice while they caused this process.

They saw a swelling occur and the brain cells became starved of oxygen. The nerve cells were damaged -- specifically the dendrites, the long, thin spikes that stretch from one nerve cell to another.
