Amnesia

A neurological condition characterised by the partial or complete inability to recall past experiences (retrograde amnesia) or to form new memories (anterograde amnesia). Amnesia results from damage to brain structures responsible for memory processing, commonly caused by stroke, brain injury, tumour, oxygen deprivation, chronic alcoholism, or surgical intervention. The severity and type of memory loss varies depending on the location and extent of brain damage. People with amnesia often retain procedural skills and general knowledge but struggle with everyday tasks that depend on episodic memory, such as remembering appointments, recent conversations, or where they placed objects.
