You can root that top portion by removing the larger leaves, and sticking it in some soil. It looks like it has an infection. This can be cured by mixing peroxide into your water the next time you water. Replace one third of the water with peroxide.
This will cure the infection. Now to prevent it from happening again, you will need to wait until the plant almost completely dries out between each watering.
