TYPES OF AMNESIA
TRANSIENT GLOBAL AMNESIA


Transient global amnesia is a sudden, temporary
episode of memory loss that can't be attributed to a
more common neurological condition, such as epilepsy
or stroke.
During an episode of transient global amnesia, your
recall of recent events simply vanishes, so you can't
remember where you are or how you got there. You may
also draw a blank when asked to remember things that
happened a day, a month or even a year ago. With
transient global amnesia, you do remember who you
are, and recognize the people you know well, but that
doesn't make your memory loss less disturbing.


There is a Inability to form new memories and to recall the recent
past events.
The person know their personal identity despite memory loss
they have a normal cognition, so the ability to recognize and name
familiar objects and follow simple directions is still intact
there were no focal brain damage or deficits during or after the
attack.
The attack resolved within 24 hours.
The attack was witnessed by a capable observer and reported as
being a definite loss of recent memory
The individual simply cannot recall anything that happened outside
the last few minutes, while memory for more temporally distant
events may or may not still remain
Gradual return of memory
The individual asks repetitive questioning, usually of the same
question, For example, "What am I doing here?" or "How did we get
here?"
CAUSES
-Precipitating Events



In precipitating event, past, dramatic, recent event that have happened
days or weeks before the episode of TGA, where the patient has been
exposed to high levels of anxiety and depression due to being
emotionally instable, leaving the patient vulnerable to many stressful
trigger may contribute causes towards the TGA. As well as this if the
patient as experienced a phobic or emotionally changeling precipitating
event, for example suicide .
Other triggers include, vigorous over exercises, emerging in extremely
cold or hot water, Exposure to extreme weather conditions and
temperature changes.
A static I found is that in TGA attacks precipitating events occur at at
least one-third of the time. For females, this event is more often of a
strong emotional character; in males, it is more often related to some
physical exertion
-Migraines

Migraines are often incorporated and reported in cases of TGA. However,
migraines do not appear to occur simultaneously with TGA nor serve as
a precipitating event. Headaches frequently occur during TGA, as does
nausea, both symptoms often are associated with migraines
RETROGRADE AMNESIA

In, retrograde amnesia your ability to remember recent
memories is lost and they are less likely to be recovered, while
more remote or deeply ingrained memories may be spared as
well as they will be easier to recall due to strengthening over
time.

Retrograde Amnesia, memory of the events or circumstances
that led up to the resulting injury may never be able to be
recovered. So, the patient loses the time that led up to the
injurious event. This memory loss can consist of a few minutes
or hours, or up to several years. However some more traumatic
events may flood back due to the intensity of emotions and
situation of a major event in the person memory but reason
behind the event may be never recovered.

Problems with information recall and the formation of old memories, people,
location etc.
Disorientation
Events in previous history of life and time line is perplexed
Lack of insight of RA, refuse to deny they association with disease
No emotional reaction to RA
Personality changes, a person becomes bleak and any distinctive personality
traits are lost
Confabulation of memory, filling in past events with false information that the
person believes to be true
slow progression of older memories being restored over time
wandering and traveling, and
Acceptance of a new identity as a result of inaccessible memories often
happens
Many of the TGA symptoms also occur
CAUSES
-A traumatic brain injury

Traumatic brain injury (TBI), occurs from an external force that causes structural damage to the
brain, such as a sharp blow to the head. The impact knocks the brain causing internal damage.
However is doesn’t affect the person's ability to form new memories, but normally, there is a
very gradual recovery, despite this a dense period of amnesia immediately preceding the
trauma usually persists.
-Traumatic events


a traumatic situation that individuals wish to consciously or unconsciously avoid a specific
situations, where emotions are heighted and vulnerability or isolation are present.
The person often blanks out this event due to severity or stress of the traumatic event,
although it may still lye in the person subconscious. Instances of wandering and traveling, and
acceptance of a new identity as a result of inaccessible memories often happens .
-Controlled induction and surgery


Often there is treatments with Electroconvulsive therapy (ECT), where controlled electronic
impulses are sent trough the body at different levels of severity, as a form of treatment for
diseases such as depression. If the shock are to high it can cause brain damage and a person
to black out and RA to occur.
Also in surgery it as been found when doctors or scientist are working on patients sometimes
the removal or damage to a section of the brain can occur and RA is formed.

CAUSES FOR OUR CHARACTERS AMNESIA
-Precipitating and


Traumatic events
We are having are character have a memory about having suicide at the beginning of the
trailer. This is to hint this may be the cause of why he has amnesia as suicide is often
associated with high emotions from the victim like a traumatic event. we also including it to
inflict mystery and provoke curiosity into why he is trying to commit suicide in the first place.
The suicide event also may flow into the aspect of wandering and exploring that we are having
our protagonist do around the hospital from the trauma of the suicide.
-Brain Injury

Hinting that the protagonist did in face jump of a high building and but still
awakened implies that he may of hit the ground, therefore is head but survived.
Giving another explanation of why he has memory loss and no recollection of his
whereabouts.
-Controlled Induction

Although we aren't including surgery or Electroconvulsive therapy, the idea of Controlled
induction of memory is present in the aspect of our protagonist entering the dark TV room
and getting transfixed by gory images. These shots imply that the images and TV may be
contributed or towards inevitable caused onset of amnesia .
