1.1 The term Dementia is used to describe people who have symptoms which include, loss of memory, confusion, speech and language problems, also have changes in personality and behaviour. Also  these symptoms interfere with the persons ability to function normally with even sometimes the easiest tasks in life like getting washed, feeding themselves . Normally this affects people who are over the age of 65, but can affect younger people. People tend to be diagnosed with dementia when they have had any of the problems for about 6 months or more. Symptoms can be mild where its seems the person is just forgetfull  but can develop into  full blown dementia where the person forgets practically everything including where they are what they have just done five minutes before and even who their family are they can even forget who they actually are.
1.2 The key functions of the brain that are affected by dementia are hindbrain which regulates functions such as breathing swallowing blood circulation and maintainging balance, the Midbrain which regulates vision,hearing and body movement, the Forbrain deals with receiving and processing information, the Spatial is to awarness of your immediate surroundings, Perception is a process in which a person detects and interprets informaiton within the enviroment.  The Forebrain is the main section of the brain that is affected by dementia because if you cant process information this causes the persons not to be able to process the information which is needed to carry out tasks.

This can make the diagnosis of dementia quite hard,with the symptoms being similiar,but also with depression you can have a rapid mental decline, a negative view on life...
