AB Dementia  is  an  acquired  deterioration  in  cognitive  ability  that  impairs  the  successful  performance  of  activities  of  daily  living.  Memory  is  the  most  common  cognitive  ability  lost  with  dementia;  10%  of  persons  age  >70  and  20–40%  of  individuals  age  >85  have  clinically  identifiable  memory  loss.  Other  mental  faculties  are  also  affected  in  dementia,  such  as  language,  visuospatial  ability,  calculation,  judgment,  and  problem  solving.  Neuropsychiatric  and  social  deficits  develop  in  many  dementia  syndromes,  resulting  in  depression,  withdrawal,  hallucinations,  delusions,  agitation,  insomnia,  and  disinhibition.  Dementia  is  usually  chronic  and  progressive.
