““Short-term memory is the memory process that allows you to do many things at once, or ‘multitask.’ For example, when you are cooking breakfast, you can remember how long the eggs have been boiling, when the frying bacon needs to be turned, when in the process to turn on the coffee maker and start the toast, and when you can fit in peeling the oranges. In contrast, a person with short-term memory deficit can concentrate on only one thing at a time, and if a second thing distracts them, the first may leave their consciousness completely. Trying to concentrate on many things at once, as we do if we are multitasking, becomes difficult, and then impossible, for people with short-term memory loss. Think about the process of making breakfast described above. The cook has to remember to check on each item of food being prepared. They also have to recall all the steps required to cook each item from start to finish. Not only that, but they also need to use their short-term memory to remember which of those steps they’ve already done and what comes next. People with short-term memory loss due to dementia usually stop doing complex tasks like cooking very early in the disease process. These complex tasks are very common in the work world. If a person is still working when they start to develop dementia, they often lose their job because they can no longer function the way they need to in order to complete their work. Speaking from my own experience as a nurse on a hospital ward, I had to remember the names, diagnoses, room and bed number, and general health conditions of a dozen or more people; also, what medications they got and when, what care and treatments they needed to receive and how well those went, whether or not I’d recorded all this information, what I needed to ask physicians when they arrived on the ward; and, still be cooperative with the many interruptions that happened every hour. Most jobs have similar complexities. They require a reliable short-term memory.””
