Yes, it makes sense. The article implies that there are losses of a specific neuron which resides in a specific part of the brain which is thought to control sleep. The neurons in this story are tasked with helping an individual sleep, thus the title 'Loss of neurons for sleep...' is correct. The neurons in this article are used by the individual FOR sleeping. I could understand someone interpreting it as a barter or trade. "I will give you these neurons FOR that sleep", however that's not intended. Perhaps "Loss of neurons (for sleep).." or "Loss of neurons which aid in sleep.." would be even more clear.
