oa Central African Journal of Medicine - How should we investigate TIAs

Volume 37, Issue 3

The incidence of Transient Ischaemic Attacks (TIAs) has consistently increased internationally in the recent years. The principle reasons for such an increased incidence are the increase in the ageing population and the increased diagnostic pick up rate of the in-life condition. It is imperative that the diagnosis of TIAs be kept in mind by the attending clinician so that appropriate investigations could be instituted urgently. Since the behaviour pattern of recurring emboli is stereotypic (i.e. the subsequent platelet emboli tend to follow the previous path of embolisation), the damage to the infarcted brain is recurrent. The junctional tissue surrounding an infarcted part of the brain may reinfarct as a result of recurrent embolisation and, therefore, no single TIA should be taken lightly. Appropriate therapy should never be delayed due to a delay in respect of investigations.
