Who is commonly affected by memory loss?
Everyone at any age can be affected by memory loss. Most of the causes, beside natural accidents such as falls or traumatic incidents are closely related to age and general health. In recent studies they have found that there has been more and more cases of young adults showing increase in memory loss. It still is even more common to see elder people have common memory loss problems, especially in the form of Alzheimer's disease.

Researchers at Gallup and the University of California, Los Angeles, did a study that shows that certain lifestyle factors may lead to early onset of memory problems. The study focused on lifestyle factors known to contribute to early onset of or contributing to memory loss these included depression, a lower education level, being physically inactive, high blood pressure, diabetes, obesity, and smoking. With over 18,500 individuals, ages 18 to 99, the results were unsurprising. (Shown in diagram)

We are seeing a significant increase in the memory loss within younger adults. The common between these young adults are they share most or all the lifestyle factors that were listed above.

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    
 

Memory Loss?

Memory Loss?


            Memory loss commonly known as amnesia is defines as unusual forgetfulness. People may not be able to remember new events, recall one or more memories of the past, or both. Memory Loss can be reoccurring. Although most of the time people will regain parts of or all of their memory back, there are also cases in which the person never regains their memory. There are two main types of memory loss:
a) Long Term Memory is defined as difficulty remembering events that occurred further in the past. When a patient has long-term memory loss, they have problems recalling stored memories, not creating new memories.
b) Short Term Memory is defined as the temporary or complete loss of the actual short-term memory which holds a small amount of information that a person needs temporarily, such as a list of things to buy at the grocery store.



 In Finding Nemo, Dory has short term memory loss.
