Struggling to RememberThe brain gathers, processes, and stores information in a number of ways. When we perceive something, a set of cells in our brain is activated in a specific sequence. If not fully pursued, the perception fades and the cells return to their original state (1). However if the thought or perception is entertained, the cells interact, forming a network of communicating and signal transmission. The set of cells becomes a memory engram a neuronal network representing encoded fragments of past experiences. The set of cells with facilitated synapses is now the anatomical correlate to the memory (1). commemoration of an event or rather activation of an engram can occur via a stimulus to any of the parts of the brain where a neural community for the memory exists. Once the engram is activated the hippocampus facilitates activity at the synapse, strengthening the relationship between neurons in the network, thus solidifying the memory (1). The chances of retentiveness i mprove by this process of consolidation. Thus, memories play an integral role in our lives they are the bits and pieces of our experience. Just as remembering plays a critical role in shaping or lives, so does the process of forgetting. What happens when we forget or lose our memories? Perhaps forgetting is due to poor encoding, an error in the process transforming something a soulfulness sees, hears, thinks, or feels into a memory (2). Maybe the absence of proper stimulus prohibits retrieval of information or maybe forgetting serves as a drive to notice us sane, purging the brain of irrelevant data. If we remembered everything, we should on most occasions be as ill of ass if we remembered nothing (William James, The Principles of Psychology).Memory plays a key role in mental health and thus its impairment is one of the most distressing psychological dysfunctions. Amnesia or memory loss is an constitutional case of forgetting that occurs often as a result of severe brain injury or traumatic experience. The term amnesia is associated with a broad syndicate of memory deficits ranging from Alzheimers disease and anterograde and retrograde amnesia to infantile and childhood amnesia and progressive memory loss due to aging (3). However, clinical cases of amnesia tend to fall into two main categories-psychogenic amnesia and organic amnesia. Psychogenic amnesia refers to instances in which memory loss is presumed to have a purely psychological basis. Traumatic events may have altered the patients brain but no physical damage is observed.
