F04: Organic amnesic syndrome, not induced by alcohol and other psychoactive substances

Your memory is not normal. There is a physical reason for this.

Your memory has got worse. With this condition, one can no longer memorize things for a short time. One also no longer remembers events from the past. There is a physical reason for this. For example, it may be a circulatory disorder in the brain, the lack of certain nutrients and vitamins.

However, you can still memorize immediate things, for example repeat something that is said straight away. You may find it difficult to learn new things.
