The ASAP Dictionary of Anxiety and Panic Disorders

Laughter - an effective coping skill against fear, anxiety or depression. Laughter can temporarily alleviate the symptoms of anxiety and depression, but is generally not practical during a panic attack. Some studies suggest that laughter may have neurochemical benefits regarding chronic anxiety or pain. See humor.

Libido - sexual drive, urge or desire. For both men and women, a normal libido requires healthy levels of both testosterone and dopamine (dopamine inhibits prolactin which can dampen libido). A loss of libido may indicate anorgasmia.

Life Coach - anyone who provides life coaching. Also see motivational speaker.

Life Coaching - the application of motivational techniques with intent to encourage will. Since life coaching is generally not clinical in nature, it is not formally considered a psychotherapy. Also see motivational speaking.

Lightheaded - feeling that you might faint. May include floating sensations.

Light Therapy - the use of light to alleviate a disorder. Often used to treat seasonal affective disorder. Since different kinds of light sources emit different spectra (collection of light wavelengths), the type of light source is important. In other words, simply having more light may not help if the light does not have the right spectrum.

Limbic System - a group of subcortical brain structures; includes amygdala, cingulate gyrus, fornix, hippocampus, hypothalamus, mamillary body, midbrain, olfactory bulb, parahippocampal gyrus, pons. Though limbic structures do play significant roles in emotions such as anxiety, the limbic system is not the complete governer of emotion (as was once thought).

Lyme Disease - an illness acquired from tick bites. Symptoms may resemble an anxiety disorder and include fatigue, concentration difficulties, joint pain. Can be medically diagnosed with a blood test and treated with antibiotics.
