Addiction - an acquired dependence resulting from excessive exposure to a substance or behavior. Reduction or removal of such exposure often results in physical and/or psychological distress known as a withdrawal syndrome. Since the symptoms of withdrawal syndromes and anxiety disorders are extremely similar, caution should be used in distinguishing the two. Characteristics of addiction may include increasing tolerance, loss of control or functionality, or dismissal of adverse consequences. Causes of addiction include unwise recreation, self-medication (wittingly or unwittingly), genetic vulnerability, or inappropriate management of medication or therapy.

Adjustment Disorder - an emotional or behavioral disorder resulting from difficulty adapting to stressors.

Adrenal Gland - either of two endocrine glands near the kidneys that produces cortisol, epinephrine and norepinephrine.

Adrenaline - a dated term typically referring to epinephrine.

Adrenaline Rush - commonly, the arousal, excitement or thrill associated with an experience that is novel and/or risky. Symptoms are usually associated with the action of epinephrine and dopamine.

An example of allostatic balance is a rise of epinephrine in response to exercise, stress or perceived danger, followed by a fall of epinephrine during relaxation.

Alternative Medicine - techniques used to treat a disorder or disease which are not yet formally embraced by mainstream medicine. These techniques may have a long history of use in traditional healing, or are sometimes newly discovered or developed. Whether old or new, the distinguishing characteristic of an alternative medicine is that it's therapeutic value is based on anecdotal accounts rather than controlled scientific study. Such lack of scientific evidence does not necessarily rule out a true therapeutic value, but simply means that a therapeutic value has yet to be proven scientifically and, consequently, is not yet recognized by mainstream medicine. In other words, alternative medicines may have an unknown or misunderstood value beyond a simple placebo. Due to uncertainty, limited regulation and occasional exploitation, caution should be used when exploring such options. Even though alternative medicine is not "formally" embraced by mainstream medicine, many medical doctors like to remain open-minded on the subject and should be consulted before trying such techniques. Forms of alternative medicine include acupuncture, aroma therapy, chiropractic, cranialsacro somatic therapy, herbal remedies, holistic medicine, homeopathy, magnets, naturopathy, radionics, therapeutic touch.

Such medications are sometimes found useful in the treatment of anxiety disorders, but tend to still be called antidepressants because doctors originally used them to treat depression.

Antidepressant Discontinuation Syndrome - any withdrawal syndrome associated with antidepressant medication.
