Depressive Disorders

Have you experienced depression in your life, as an adolescent or adult? Do you still struggle with feelings of sadness or unhappiness, low mood, obsessive thoughts, poor sleep patterns, social withdrawal, feelings of guilt, irritability, and low energy?

There are many different subgroups of depression. Early life trauma, loss, and physiological deficiencies in feel good neurotransmitters (such as dopamine and serotonin) are all possibilities as to why depression creeps in. There is not one kind of depression, many are resistant to pharmacological intervention. The EEG and brain map shows different depressive profiles.

Neurotherapy is different from traditional forms of treatment in that it allows the practitioner to observe reduce the excitation of approach behaviour networks while reducing the judgment regions of the brain. With the aid of the QEEG analyses an individual is provided with information so that they can retrain the specific areas of their brain.


Depression is a highly complex disorder. Indicators below the neck line are also relevant to depression – heart rate variability, hormone synthesized by glands (adrenal, cortisol, and thyroid). Alpha brainwave is the doorway between the limbic system and the cortex. When alpha is high, the door is usually closed. It is easy to confuse depression with head injury and ADD. The left frontal area of the brain is associated with positive emotions and approach motivation. Approach motivation is a desire to be involved with other people. The right frontal area of the brain is more associated with depression and fear, accompanied by motivation to withdraw from and avoid other people. When there is slower brainwave activity in the left frontal area, this part of the brain is more inactive and the right frontal area is more dominant. Such a person is predisposed to become depressed more easily, to withdraw from other people, and to be anxious. This may occur because of heredity (family history) or because someone has had a concussion or mild head injury in the left frontal area which produced the slowing.

The most common is elevated central Alpha  (8 – 12 Hz).

Elevated Alpha Depression Subtype QEEG Brain Maps



With QEEG based neurotherapy, aberrant areas of the brain as determined by a QEEG brain map, can gradually be trained back toward normal. It has been well documented that Transcranial Direct Current Stimulation (tDCS) applied using unique electrode placements has the ability to produce improved mood in those suffering with depression. Furthermore, this therapy has been shown to alleviate symptoms in certain cases of severe treatment-resistant depression, Seasonal Affective Disorder (SAD), and Generalized Anxiety Disorder (GAD).
