Transmissible spongiform encephalopathies (TSEs)

Also known as prion (an infectious agent composed of mis-folded proteins in contrast to all other known infectious agents like virus, bacteria, fungus etc.) diseases, are a group of progressive conditions that affect the brain and nervous system of many animals, including humans. Mental and physical abilities deteriorate and myriad tiny holes appear in the cortex causing it to appear like a sponge (hence the term 'spongiform') when brain tissue obtained at autopsy is examined under a microscope.

The disorders cause impairment of brain function, including memory changes, personality changes and problems with movement that worsen over time. (Source - Wikipedia)

Transaction Costs

The cost incurred in making an economic exchange. For example, most people, when buying or selling a stock must pay a commission to their broker; that commission is a transaction cost of the stock deal.

Or consider buying a banana from a store; to purchase the banana, your costs will not only be the price of the banana itself, but also the energy and effort it requires to find out which of the various types of banana you prefer, where to get them and at what price, the cost of traveling from your house to the store and back, the time waiting in line, and the effort of the paying itself; the costs above and beyond the cost of the banana are the transaction costs.
