Dear All
There are two types of amnesia.
Retrograde amnesia - most commonly caused by a blow to the head. In this case the person does not remember what happened a few hours prior to the accident, as the brain did not have the chance to process the information.
Anterograde amnesia - caused by a damage to the brain area which 'stores' memory (hippocampus). Here, memory from the past seems in tact, but memory of events occuring after the injury is impaired
The brain does not store memories in one unified structure, as might be seen in a computer's hard disk drive. Instead, different types of memory are stored in different regions of the brain.
LTM is typically divided up into two major headings:
declarative memory and implicit memory (or procedural memory).
Computer programs store information similarly with a separate data section and code section.
Declarative memory refers to all memories that are consciously available. These are encoded by the hippocampus, entorhinal cortex, and perirhinal cortex, but consolidated and stored elsewhere. The precise location of storage is unknown, but the temporal cortex has been proposed as a likely candidate.
Declarative memory also has two major subdivisions:
o Episodic memory refers to memory for specific events in time
o Semantic memory refers to knowledge about the external world, such as the function of a pencil.
Procedural memory refers to the use of objects or movements of the body, such as how exactly to use a pencil or ride a bicycle. This type of memory is encoded and probably stored by the cerebellum and the striatum.
There are various other categorizations of memory and types of memory that have captured research interest. Prospective memory (its complement: retrospective memory) is an example.
Emotional memory, the memory for events that evoke a particularly strong emotion, is another. Emotion and memory is a domain that can involve both declarative and procedural memory processes. Emotional memories are consciously available, but elicit a powerful, unconscious physiological reaction.
They also have a unique physiological pathway that involves strong connections from the amygdala into the prefrontal cortex, but much weaker connections running back from the prefrontal cortex to the amgydala
The pace and extent of recovery from brain injury can vary considerably, even between patients with similar injuries. The majority of recovery from brain injuries occurs within the first six months to a year after trauma, but one study (Sbordone 1994) indicates that a patient's function following severe traumatic brain injury can occur for up to ten years post injury. The pace of recovery and even the extent of recovery can be improved by proper physical and cognitive rehabilitation.
Levels of recovery are often measured in rehabilitation programs with the use of the Rancho Los Amigos Scale.Find the same attached herein.
Understand what kind of memory loss it is then proceed.
