Antidepressants work on the brain and nervous system.
The brain and nervous system consists of a series of nerves that communicate with one another. When this electrical charge gets to the end of one nerve it can t just jump across to the next. Instead, it uses a complicated and amazing system of chemicals to pass the message on to the next nerve. There are hundreds of these special chemicals, known as neurotransmitters, that travel across the tiny gap between cells and pass the message on from the first nerve cell to the next. The body turns the message off in many ways.
