<unk>  is the term for the medical condition of being unable to understand or express any signs or symbols. It is a more severe condition than aphasia, which is the inability to understand linguistic signs.<unk>  is caused by damage to the areas of the brain that process communication – more specifically, when there is damage to the left side of the brain in the areas that process communication such as Broca's and Wernicke's areas. Damage can be inflicted by physical trauma to the brain, but is more commonly caused by stroke and sometimes tumors. The onset of this condition is usually quick but not permanent. Treatment of this condition is traditional speech therapy in which the individual must relearn how to read, write, and talk. Depending on the severity of the injury, recovery can take days to years. Considerable recovery is common, but often not to the full extent of baseline ability.
