A diagnosis of<unk>  is determined using a variety of tests, such as the Palm Writing subtest. The Palm Writing subtest involves a series of trials where patients are asked to identify whether an X or an O was written on the palm of their hand. Just as numbers and shapes may be used in addition to letters, similar neurological tests can be carried out on other parts of the body, such as the forearm and the abdomen. For tests of<unk>  like the Palm Writing subtest, it is important that subjects do not see what is being traced on their palm because this can bias the subjects’ responses. Subjects can be blindfolded or a screen can be used to obstruct the subject's view of the area being tested.
