Causes of Memory loss at any age

(Source: Medical Journal)

Memory loss, also known as amnesia, is states of unusual forget fullness. This refers to a loss of the every day sense of memory responsible for knowing facts, events, information and experiences. Loss of memory is also called “Amnesic Syndrome”. People with amnesia typically are lucid and maintain sense of self but they face severs difficulties in learning new information and forming new memories. They may not be able to recall memories of past experiences and information.
Memory involves several different functions of the brain. Most studies of the brain divide memory into two kinds, Declarative and procedural. The declarative involves strong facts and the procedural involves skills and habits.
There are at least three general types of amnesia.
1. Anterograde: This type of amnesia follows brain trauma and characterized the inability to remember new information.
2. Retrograde: This form of amnesia is opposite of anterograde amnesia, the victim can recall events that occurred after a trauma but can not remember previously familiar information.
3. Transient Global Amnesia: This type of amnesia has no consistently identifiable cause but researchers have suggested that migraines or ischemic attacks may be the trigger.

Childhood or infantile amnesia refers to person’s inability to remember specific events from childhood and infancy, typically prior to the age of four. Famed psychoanalyst sigmund freud believed that childhood amnesia was a response to sexual repression. It has been hypothesized that memories need to be stored conceptually and associated with words and meanings that people don’t attain until about the age of four. It is also possible that young child’s brain does not have sufficient development to properly store memories.
Infant and childhood stress have been linked to memory decline at an early age. A 2005 study by the UC Irvine School of Medicine suggests that associated with parental loss, abuse or neglect may contribute to the type of memory loss during middle age years.
