Anorexia: An eating disorder characterized by markedly reduced appetite or total aversion to food. Anorexia is a serious psychological disorder. It is a condition that goes well beyond out-of-control dieting. The person with anorexia, most often a girl or young woman, initially begins dieting to lose weight. Over time, the weight loss becomes a sign of mastery and control. The drive to become thinner is thought to be secondary to concerns about control and fears relating to one's body. The individual continues the endless cycle of restrictive eating, often to a point close to starvation. This becomes an obsession and is similar to an addiction to a drug. Anorexia can be life-threatening. Also called anorexia nervosa.
Anxiety: A feeling of apprehension and fear characterized by physical symptoms such as palpitations , sweating, and feelings of stress . Anxiety disorders are serious medical illnesses that affect approximately 19 million American adults. These disorders fill people's lives with overwhelming anxiety and fear.

Blood pressure: The blood pressure is the pressure of the blood within the arteries. It is produced primarily by the contraction of the heart muscle. It's measurement is recorded by two numbers. The first (systolic pressure) is measured after the heart contracts and is highest. The second (diastolic pressure) is measured before the heart contracts and lowest. A blood pressure cuff is used to measure the pressure. Elevation of blood pressure is called "hypertension".

Appropriate treatment, however, can help most people with depression.

Hypochondriasis is now generally recognized to be a psychiatric disorder. This disorder is characterized by a preoccupation with body functions and by the interpretation of normal body sensations such as sweating and minor abnormalities such as aches as major problems of medical importance. Hypochondriasis usually begins in the teen-age years and young adulthood. Its onset is sometimes associated with an experience in which someone close, often a loved one, becomes seriously ill or dies.

Muscle which is responsible for moving extremities and external areas of the body is called "skeletal muscle." Heart muscle is called "cardiac muscle." Muscle that is in the walls of arteries and bowel is called "smooth muscle."

Nerve: A bundle of fibers that uses chemical and electrical signals to transmit sensory and motor information from one body part to another. See: Nervous system.
Nerve cell: See: Neuron.
Neuron: A nerve cell that sends and receives electrical signals over long distances within the body. A neuron may send electrical output signals to muscle neurons (called motor neurons or motoneurons) and to other neurons. A neuron may receive electrical input signals from sensory cells (called sensory neurons) and from other neurons. A neuron that simply signals another neuron is called an interneuron.

The results obtained in the two groups are then compared to see if the investigational treatment is more effective than the placebo.
Prognosis: 1. The expected course of a disease .

Psychology: The study of the mind and mental processes, especially in relation to behavior. There are a number of fields of psychology. Clinical psychology is concerned with diagnosing and treating disorders of the brain, emotional disturbances, and behavior problems. Child psychology is the study of the mental and emotional development of children and is part of developmental psychology, the study of changes in behavior that occur through the life span. Cognitive psychology deals with how the human mind receives and interprets impressions and ideas. Social psychology looks at how the actions of others influence the behavior of an individual.

See the entire definition of Serotonin
SSRI: Abbreviation for selective serotonin reuptake inhibitors, commonly prescribed drugs for treating depression . SSRIs affect the chemicals that nerves in the brain use to send messages to one another. These chemical messengers, called neurotransmitters, are released by one nerve and taken up by other nerves. Neurotransmitters that are not taken up by other nerves are taken up by the same nerves that released them. This process is termed "reuptake." SSRIs work by inhibiting the reuptake of serotonin, an action which allows more serotonin to be available to be taken up by other nerves.

Synapse: The point of connection usually between two nerve cells. Specifically, a synapse is a specialized junction at which a nerve cell (a neuron ) communicates with a target cell. The neuron releases a chemical transmitter (a neurotransmitter ) that diffuses across a small gap and activates specific specialized sites called receptors situated on the target cell. The target cell may be another neuron, or a specialized region of a muscle cell or a secretory cell (a cell than can make and secrete a substance). Neurons can also communicate through direct electrical connections (electrical synapses).
