ANTEROGRADE & RETROGRADE AMNESIA
Amensic conditions are most frequently encountered by physicians and therapists following an injury to the brain, such as due to head trauma, stroke, neoplasm, or encephalitic condition (Hodges & Warlow, 1990; Lynch & Yarnell, 1973; Miller, 1993; Russell, 1971; Yarnell & Lynch, 1970, 1973). Following a signficant head injury or stroke there may be a period of amnesia for events which occured just before and just after the time of injury (Hodges & Warlow, 1990; Russell, 1971), even if consciousness is not lost (Yarnell & Lynch, 1970, 1973).
