Possible Factors for Anxiety/Restlessness

Anxiety can be caused by several things including stress, hormonal imbalances, and neurotransmitter imbalances. Serotonin, norepinephrine and GABA are neurotransmitters thought to be involved in the development of anxiety disorders. Normal serotonin activity appears to be important in maintaining feelings of well-being. Deficiencies in serotonin may be related to the development of anxiety disorders. Norepinephrine is a close cousin to epinephrine, also known as adrenaline. The "fight or flight" response to stress is associated with elevated adrenaline and cortisol levels, and the stress-related sense of being in a state of fear.
