Retrograde amnesia
ICD-10 R41.2 is a billable code used to indicate a diagnosis of retrograde amnesia.
Retrograde amnesia is a type of memory loss that affects the ability to recall past events, experiences, or information that occurred before the onset of amnesia. This condition can arise from various causes, including traumatic brain injury, stroke, psychological trauma, or degenerative diseases. Patients may retain the ability to form new memories but struggle to access previously stored information. Symptoms can vary in severity and may include confusion, disorientation, and difficulty recalling personal history or significant life events. Clinical evaluation often involves a thorough history and neurological examination, alongside imaging studies such as MRI or CT scans to identify any structural brain abnormalities. Neuropsychological testing may also be employed to assess the extent of memory impairment and differentiate retrograde amnesia from other cognitive disorders. Understanding the underlying cause is crucial for effective management and rehabilitation.
