The theory concerns the relative strength of memories over time, which is not directly testable. Instead, scientists investigate the processes of forgetting , and recollection. [5] Ribot's law states that following a disruptive event, patients will show a temporally graded retrograde amnesia that preferentially spares more distant memories.
In neurology, retrograde amnesia (RA) is the inability to access memories or information from before an injury or disease occurred. [1] RA differs from a similar condition called anterograde amnesia (AA), which is the inability to form new memories following injury or disease onset. [ 2 ]
Semantic retrograde amnesia involves loss of generic, lifelong knowledge, as in the various forms of aphasia or agnosia, and also loss of learned motor skills, as in the various types of apraxia. Its primary focus is on retrograde amnesia for specific, usually time-limited, knowledge.
Amnesia is often caused by an injury to the brain, for instance after a blow to the head, and sometimes by psychological trauma. Anterograde amnesia is a failure to remember new experiences that occur after damage to the brain; retrograde amnesia is the loss of memories of events that occurred before a trauma or injury.
Head trauma is a very broad range as it deals with any kind of injury or active action toward the brain which might cause amnesia. Retrograde and anterograde amnesia is more often seen from events like this, an exact example of a cause of the two would be electroconvulsive therapy, which would cause both briefly for the receiving patient.

Focal retrograde amnesia (FRA), sometimes known as functional amnesia, refers to the presence of retrograde amnesia while knowledge acquisition remains intact (no anterograde amnesia). Memory for how to use objects and perform skills ( implicit memory ) may remain intact while specific knowledge of personal events or previously learned facts ...
