If you will be given a memory test, you should take it because you agree with the premise that your loss of personal memory is real. The implication, of course, is that if you are claiming to have loss of personal memory because you do not wish to be asked personal questions that are offensive or that cause you grief, you should not agree to the personal memory test.
The personal memory test is not a lie detector. You can not be accused of deliberately forgetting personal knowledge about your friends, relatives, or events in your own life. You might be accused of malingering, which is a term that means you are faking a disorder for your own personal reasons. Whatever your reasons, you can refuse to take a personal memory test if you choose. If you agree with the testing of your personal memory, there is no way that you can prepare for the test on personal memory. You do not want to visit relatives who might tell you about those areas of your life that you have forgotten.
You should take a personal memory test by trying to get a good night's sleep and having a meal before you go for the test. You want to be as forward in your answers as you can. Your answers should be spontaneous, since they will be based on questions about your personal life. If anyone has coached you or tried to prepare you for taking a test on personal memory, they are not being ethical.
Many times following trauma to the head, people will lose their memory. Those memories that are lost can be from a part of your personal life or you can lose all of your memories and have total irreversible amnesia. If you were traumatized as a result of an accident, your loss of memory might be challenged by individuals who are fearful that you might have a lawsuit against them. Therefore, if these are the reasons why you are agreeing to take a test on personal memory, you should take someone with you like an attorney or a friend. Society being what it is most people who see someone victimized by loss of memory will try to take advantage of the victim. That is not an understatement.
If you are taking a test on personal memory because you are arrested and can't remember who you are or where you came from, you should ask to have a lawyer present or to consult with a lawyer. Your rights while a victim of amnesia can't be protected because you have no memory of your past and your credibility about your recent memory might be questioned. On the other hand, if you are not in any legal trouble and will be tested by a therapist or a friend, you can prepare for your test on personal memory by trying various relaxation exercises.
These tips on relaxation, slowing down your breath deliberately, taking a warm bath, turning off the television and radio, are helpful. You can't do anything more than do your best and when asked questions that will test your recall of numbers in sequence, don't berate yourself for not being able to respond correctly.
