What is amnesia?
Amnesia is when you lose the ability to memorize information or events that have occurred in your life. In simpler words, amnesia is the loss of memory.
Amnesia is usually just a temporary disorder, but sometimes it can last forever. It can last a few seconds to a few hours, but it can also last days, weeks or even months.
Usually after you get amnesia and you recover, you have no memory of actually having amnesia.
There are two main types of amnesia, anterograde amnesia (where you are not able to memorize new things that you have just learned) and retrograde amnesia (where the memorizes that already exist are completely forgotten). There are two other types of amnesia as well. Those two types are, post-traumatic amnesia (a period of time when you lose your memory or you are in a state of confusion usually after a traumatic brain injury) and psychogenic amnesia (caused from a mental or emotional injury). So in total, there are four different types of amnesias.
