What causes anxiety biologically?

Sometimes, doctors talk about biological causes, such as genetics, brain chemistry and personality. Or they might talk about life events, such as the death of a loved one, long-term stresses, trauma and abuse. Often, a combination of these things can lead to anxiety.
