Please note: This is a companion version & not the original book. Sample Book Insights:#1 When deciding whether to add medication to your anxiety management, it is important to understand what they do and how they work so that you have clarity about the benefits and limits of drug therapy.#2 The brain has been studied and understood better in recent years, and this has led to the discovery of how some parts of the brain and neurotransmitter function contribute to feelings of anxiety.#3 The central nervous system is made up of the brain and spinal cord. The peripheral nervous system includes all the nerves that go to and from the spinal cord, and it branches into two subsystems: the autonomic nervous system and the somatic nervous system.#4 The brain is a network of billions of neurons that can connect with thousands of other neurons. The neurons send messages to each other by means of neurotransmitters, which are the messengers. The meaning of a message is determined by who is reading it.
