What investigation when?

Recognising the need for investigation and deciding which investigations to consider is often
the most difficult task. Investigations that may be considered are outlined in Table 2.
Obviously, some are highly specific and more invasive, and a high index of clinical suspicion
is therefore required to direct the investigation required. Recognising that intrinsic pathology
is present may be difficult in the early stages of presentation of many disorders, and constant
re-evaluation of the individual may be necessary.
