Document Summary

Important in providing an overview of the condition necessary for treating patients and in prognosis for recovery, but may be difficult to interpret theoretically. In addition to memory deficits such patients will typically have other problems, particularly attentional, making it difficult to separate the memory deficits form other factors. Group studies approach involves selecting patients whose damage is broadly associated with specific disease or cause. Ex: traumatic brain injury (tbi) caused by a blow or jolt to the head, or by a penetrating head injury. Severity ranges from (cid:498)mild(cid:499) (cid:523)brief change in mental status or consciousness(cid:524) to (cid:498)severe(cid:499) (cid:523)extended period of unconsciousness or amnesia after the. Korsakoff syndrome result of drinking too much and eating too little, in which memory deficits. The biological basis of memory: syndrome (cid:523)amnesic syndrome, alzheimer"s disease(cid:524) cognition (ltm, wm, attention) neural systems (hippocampus, frontal lobes) signaling pathways (dopamine, monamine oxidase) genes (drd4, maoa).
