Your Elder is suffering from a form of spongiform encephalopathy.

你的长老患的是一种海绵状的脑病。

Your neurology department loaned me a culture of prions for my research on bovine spongiform encephalopathy.

你们神经科学部门借了我朊病毒培养箱来协助我牛海绵状脑病的研究。

In particular, Prion disease creates holes in the brain, giving it a spongiform appearance and ultimately causing death.

特别是，朊病毒病会在大脑中形成一个个洞，使其看起来像海绵一样，最终导致死亡。
