[Brain imaging of patients with memory disorders].

Indications for brain imaging include potentially treatable intracranial causes (e.g. normal-pressure hydrocephalus, tumors, subdural hematoma) and especially characteristic features of memory disorders and differential diagnostics of such conditions. Since the primary structural changes in the most common progressive memory disorder, Alzheimer's disease, are seen in the inner temporal lobe, appropriate imaging of these structures is essential in early diagnosis.
