Does selective amnesia really exist?

Organic problems, no selective amnesia.

Selective amnesia is actually caused by psychological factors.

Usually clinical amnesia is more common, such as transient amnesia. At this time, trauma is common, such as sudden fainting and waking up after severe brain injury. This process may not exist. The second is ischemia. For the location of the memory center, its blood supply is suddenly blocked, embolized or vasospasm, leading to ischemia. He may suddenly say who I am and where I am. I don't know. But this situation will get better after a period of time, usually a few minutes or hours. This is the so-called complete transient forgetting, and there are many reasons for it. There is also Alzheimer's disease, also known as Alzheimer's Harmo's disease. The first thing that these patients lose is their recent memory, that is, they can't store things or put boxes down after their brain functions are abnormal. Therefore, such people often have these memories of the past, but the memories of the present may not, so they often forget things and forget where they are going. So the real so-called, such as the memory of someone in the movie does not exist, or the memory of a certain segment does not exist. In this case, most people may have mental and psychological problems.
