Chapter Outline

Introduction

The brain, one of the most important organs of the body, controls and coordinates all bodily functions including movement, sensation, thought, memory, and emotion. The brain receives information from neurons, interprets that information, and then responds via either voluntary or involuntary actions. When the brain is affected by disorders, such as epilepsy, seizures, migraines, and intracranial emergencies, the proper functioning of the body can be severely impaired (see Figure 12.2). This chapter will delve into these disorders, their impact on the brain, and common drugs used to treat these conditions.
