Memory Loss Causes

There are several possible causes of memory loss (including short term memory loss). For the purpose of a discussion on possible causes, memory loss is defined as a loss of ability to form new episodic and semantic memories, or recall fairly recent episodic or semantic memories.

Memory loss is distinct from forgetfulness. Forgetfulness is the occasional lapse of memory, such as misplacing your car keys, forgetting the name of an acquaintance (but not a close friend), or not remembering the title of a recent movie you watched (but having the title “at the tip of your tongue”).
