What happens? And Why?

What happens? And Why?
Your memory lives in the cerebrum part of your brain. Which is the largest section of your brain, it makes up 85% of the brain's weight.
The hippocampus plays an important role in the formation of new memories about experienced events. Damage to the hippocampus does not affect some types of memory, such as the ability to learn new skills but instead affects our stored memories. There are two separate hemispheric sections to the hippocampus. One on either side of the brain. Miraculously if one side of the hippocampus is damaged or cut off from its blood supply the other can work normally and our memory is barely or not at all affected. If both sides are damaged or cut off from its blood supply even by the slightest bit our memory can be affected significantly.
Emotional experiences and events are somewhat fragile and take a while to be completely set into memory. This slow process, referred to as consolidation, allows emotions to influence the way the memory is stored. This is considered memory consolidation.
Memories are started as Sensory Information form our outer nervous system, and they automatically become short-term memories. With excessive rehearsal and through Consolidation the memories become long-term memories.










When this part of the brain loses blood or is majorly damaged in any sorts the possibility of either or both short and long term memory loss chances will increase significantly.

There are many different reasons for memory loss, most cause short term and need extremely severe circumstances to cause long term memory loss. Some of the more common causes include:
A) Alzheimer's Disease
B) Concussion or Traumatic Brain Injury
C) Stroke 
D) Seizures
E) Brain Tumors
F) Epilepsy Overview
