Depression

Depression and glutenWhat Is Depression?

[dropcap]D[/dropcap]epression is a mood disorder characterized by absence of cheerfulness, dejection, and loss of interest or pleasure in living, making the person dysfunctional and unable to cope with or perform tasks of daily living.

More than a feeling, this negative psychological status can range from mild to profound and can involve other parts of the body, causing physical problems such as poor digestion, constipation, weight gain or weight loss, mentrual irregularities in females, and impotence in males.

Q: How is depression identified?

A: According to the American Psychiatric Association, depression is a psychic condition that lasts for more than a month and involves four or more of these symptoms:

  • Abnormal appetite.
  • Diminished ability to concentrate or think properly.
  • Feelings of worthlessness.
  • Low energy or fatigue.
  • Physical inactivity or hyperactivity.
  • Sleep disturbances.
  • Thoughts of death.

Grief or sadness at the loss of a loved one or a similar event or remorse for sin is normal. However, depression that is prolonged usually involves imbalances of nerve chemicals called neurotransmitters. Imbalances can result from health disorders such as hormonal imbalances, low blood sugar, stress, drug side effects, or nutrient deficiencies.

Brain Blood Flow Abnormalities

[dropcap]B[/dropcap]rain blood flow abnormalities, or cerebral perfusion abnormalities, such as spasm of blood vessels causing inadequate blood flow to the brain, are characterized by impaired brain function and thinking.

Q: What is cerebral perfusion?

A: Cerebral perfusion is the flow of blood in the brain. Blood supply to the brain comes from 4 major vessels: 2 carotid arteries and 2 vertebral arteries.

Cerebral perfusion abnormalities can be diagnosed using perfusion computed tomography (CT). CT scan is a technique that allows rapid qualitative and quantitative evaluation of cerebral perfusion by generating maps of cerebral blood flow (CBF), cerebral blood volume (CBV), and mean transit time (MTT). The technique is based on the central volume principle (CBF = CBV/MTT) and requires the use of commercially available software employing complex deconvolution algorithms to produce the perfusion maps.

Perfusion CT has been found to be useful for noninvasive diagnosis of cerebral ischemia (diminished blood flow) and infarction (no blood flow) and for evaluation of vasospasm (intermittent blood flow through vessels).1
