INTRODUCTION

Human caffeine use is typically chronic. However, many of the studies that explore the actions of caffeine are acute studies, both in animals and humans. It is therefore important to realize that there are, in several instances, important differences between the effects of acute and long-term treatment (see Jacobson et al., 1996). We will discuss such differences in relation to two potentially important outcomes: damage following ischemia and seizure susceptibility.
