Mood disorder

Anergia
Lack of energy or passivity.
Psychomotor agitation
Constant involvement in some tension-relieving activity, such as constantly pacing, biting one’s nails, smoking, or tapping one’s fingers on a tabletop
Psychomotor retardation

Significant changes from normal functioning in those activities necessary to support physical life and growth, such as eating, sleeping, elimination, and sex, during a depressive episode.
Hypersomnia
The spending of increased time in sleep, possibly to escape from painful feelings; however, the increased sleep is not experienced as restful or refreshing
Anhedonia
Loss of ability to experience joy or pleasure in living.
Transcranial magnetic stimulation
Noninvasive treatment modality that uses MRI-strength magnetic pulses to stimulate focal areas of the cerebral cortex.
Vagus nerve stimulation
Pacemaker like device is implanted surgically into the left chest wall from which a thin, flexible wire is threaded up and wrapped around the vagus nerve on the left side of the neck. Electrical stimulation of the vagus nerve is thought to boost the level of neurotransmitters, improving mood and the action of antidepressants.
Stressors
Psychological or physical stimuli that are incompatible with current functioning and require adaptation.
Fight or flight response
Body’s way of preparing for a situation an individuals receives as a threat to survival. Results in increased blood pressure, heart rate, and cardiac output.
General adaptation syndrome (GAS)
The body’s organized response to stress, as elucidated by Hans Selye. It progresses through three stages: 1- the stage of alarm, 2- the stage of resistance, 3- the stage of exhaustion.
Distress
A negative, draining energy that results in anxiety, depression, confusion, helplessness, and fatigue. Can be caused by such stressors as a death in the family, financial overload, or school/work demands.
