Refers to different types of memory disorders. Individuals suffering from anterograde amnesia (ICD-10: R41.1) are severely impaired in their ability to form new lasting memories. While their short-term memory is usually intact, they forget everything they experience shortly afterwards. In contrast, people with retrograde amnesia (ICD-10: R41.2) are unable to recall events which occurred before onset of amnesia. A third type of memory disorder is so-called dissociative amnesia (ICD-10: F44.0) which is characterised by an inability to recall certain episodic or autobiographic memories usually related to traumatic or stressful events. Depending on whether the memory loss is either quite generalised or rather confined to a certain period of time, different subtypes of dissociative amnesia can be distinguished.
