What is Major Depression?

Major Depression definedIt is an illness that involves the body, mood, and thoughts. It

interferes with daily life, normal functioning, and causes pain for both the person with the disorder and those who care about him or her.

A depressive disorder is not the same as a passing blue mood. It is not a sign of personal weakness or a condition that can be willed or wished away. People with a depressive illness cannot merely "pull themselves together" and get better.

Can we prove it medically?

Of approx. 30 neurotransmitters which have been identified, researchers have discovered associations between clinical depression and the function of three major neurochemicals. These substances are serotonin, norepinephrine, and dopamine.

Antidepressants influence the overall balance of these three neurotransmitters within structures of the brain.

They regulate:emotion, reactions to stress, and the physical drives of sleep,

appetite, and sexuality.

Does it affect Gender?

Men Men often conceal depression better and

are less likely to seek treatment for major depression.

See it as a feminine thing conceal with substance abuse.

While men are less likely to attempt suicide than women, men are more successful.

Rate of suicide among men increases with age, peaking at 85.

Depression in men tends to manifest itself in the form of irritability, anger, and feelings of discouragement and low self-worth.

Women Women are twice as likely as men to

experience major depression. This discrepancy may be due to the

inherent hormonal fluctuations of womanhood. menstrual cycle, pregnancy, and

menopause. Women are particularly vulnerable to

depression following childbirth, a condition known as postpartum depression. Women suffering that are likely to kill

themselves or their child.

Treatments continued

Using both medication and therapy/counseling. Behavioral Activation

Interpersonal Therapy (IPT) When the psychologist attempts to make changes to your personal social sphere rather than

the behavior and build up their social and communication skills to build better relationships.

Inherited Factors (Biological): 1) Genetic Predisposition (expression for Depression)

Constitutional (biological) vulnerability

OUTCOME Depression

Imbalances in hormone levels (cortisol and depression). There have also been MRI’s proving one with depression is affecting its cognitive processes.

Stress (Sociocultural Factors): 1) Severe life events and social status.2) Tragedies affecting life (Traumatic events)
