Effective & Trusted Medications Guide

Depression is a complex of psychological and physical symptoms. Low mood level or sadness is often the most prominent symptom. The common property of these symptoms is a decreased activity level in parts of the brain.

The Symptoms Of Depression

Depression may give one or more of these symptoms:

• Low mood level or sadness.
• Lack of joy or interest in activities that were joyful before.
• Pessimism.
• Feel of guilt of something without any substantial reason to feel so.
• Inferiority thoughts.
• Irritability.
• Slowness in the thought process.
• Slowness in interpreting sensorial stimuli.
• Slowness of digestion or other internal physical processes, and symptoms caused by this slowness, for example inflated stomach, constipation or difficulties by urination.
• Slow physical reactions.

Depression can be a mild disease that only causes some annoyance in the daily life, but can also get very serious and make a person totally unable to work and unable to participate in social life. By depression of some severity, there is also a greater risk of suicide.

Depression can occur in all age classes. In teenagers lack of interest in school work, withdrawal from social life and difficult mood can be signs of depression.

THE PHYSIOLOGICAL CHANGES THAT PRODUCE THE SYMPTOMS

By depression there is a decreased amount of neurotransmitters in parts of the central nervous system, mainly deficiency of serotonin, but also to some extend of noradrenalin, acetylcholine, dopamine or gamma-amino-butyric acid (GABA), or the nerve cells do not react properly by stimulation from neurotransmitters. A neurotransmitter is a signal substance that transmits the nerve signal through the junctions between two nerve cells.

Serotonin and noradrenalin cause nerve cells to send impulses along to other nerve cells, and thus increase the activity in the brain. Deficiency of these substances causes slowness in parts of the brain, and that again causes the depressive symptoms.

The role of GABA is the opposite, namely to slow down some nerve impulses, mainly those causing anxiety and panic response. Lack of GABA causes higher anxiety and easier panic response. Yet, lack of this transmitter also seems to cause depressive symptoms. This is because a too high activity in some brain processes may slow down other processes.

There are many causes and subtypes of depression with different physiological mechanisms involved.

TREATMENT OF DEPRESSION

Serious or prolonged depression is often treated with anti-depressive medication. Medicines used against depression generally increase the level of neurotransmitters like serotonin in the central nervous system, or they mimic the neurotransmitters.

The medications mostly used today increase the serotonin concentration by decreasing the removal of serotonin from the space around nerve cells. Examples of this medication type are: Fluoxetine (Prozac), fluvoxamine (Luvox), paroxetine (Paxil), escitalopram (Lexapro, Celexa), sentraline (zoloft).

One of the best medications for now is Wellbutrin
