Amnesia is a neurological disorder affecting memory recall and formation, often due to brain injury or disease. It includes anterograde amnesia, which hinders new memory creation, and retrograde amnesia, which erases past memories. Key brain areas like the hippocampus and frontal lobes are involved, and case studies like H.M. and Clive Wearing offer insights into memory processing and the resilience of procedural memory.

Retrograde amnesia is the inability to recall past events due to brain injury or disease
Anterograde amnesia is the inability to form new memories due to damage to the hippocampus
Procedural memory, which includes motor skills and habits, is typically spared in individuals with amnesia
Amnesia can result from brain injuries, strokes, infections, or degenerative diseases
Anterograde amnesia is often associated with damage to the hippocampus, while retrograde amnesia is linked to damage to the frontal lobes
Temporary forms of amnesia can occur due to the effects of substances like alcohol
The study of individuals with amnesia, such as H.M. and Clive Wearing, has provided valuable insights into the workings of memory
Cases like H.M. and Clive Wearing have helped differentiate between memory systems and understand the brain's capacity for memory processing
Despite the debilitating effects of amnesia, the resilience of procedural memory demonstrates the brain's remarkable adaptability and potential for targeted therapeutic interventions
