Retrograde amnesia

| No Comments

Imagine not being able to remember specific memories of your childhood, graduating from high school, your first day at the U of M, or even yesterdays events. For many individuals who suffer from retrograde amnesia this is their reality. Retrograde amnesia is one of the most common types of amnesia second to anterograde amnesia. Retrograde amnesia is a result of damaged brain regions such as the hippocampus and the temporal lobes, which are mostly associated with episodic and declarative memory. Episodic memory is the recollection of events in our lives, and that is why people who suffer from retrograde amnesia loose some of these memories. A common misconception is that memory recovery is sudden and instantaneous, however, recovery from retrograde amnesia is often very gradual, if at all. Retrograde amnesia is important because it is a known effect of Alzheimer's disease. Alzheimer's, as of right now is an incurable disease that last anywhere from three to twenty years. Personally, Alzheimer's disease is important because it was something my family had to deal with. My great grandma was a victim of this terrible disease; we would visit her periodically but as time progressed and by the end of our visits she didn't even know who we were. The worst part was towards the end of her life she no longer recognized my grandpa, her own son. It was saddening to see the memory of her life slowly fade, hopefully when day we will be able to reduce the memory lose from this disease. This video describes how Alzheimer's works and how it effects the hippocampus and memory. After researching retrograde amnesia I am still left wondering what determines which memories are going to be forgotten even if memories are spread throughout many cells and synapses?
