BioBlog: Brain Fog in Chronic Illness

By Todd Farney, DC, The Biologix Center for Optimum Health

What is brain Fog?

The brain does not feel pain when it is inflamed, instead we experience brain fog.  Brain fog is inflammation of the brain that interrupts normal processing or cognition, leading to memory loss, an inability to focus or to track, and to think.  Brain fog leads to gaps in thinking and memory and that block us from finding the words we want to say or completing cognitive tasks like driving, planning or shopping.

Brain fog is one of the most common complaints in people suffering from chronic illness.

There are 4 main factors that contribute to brain fog:

  • Brain nutrition
  • Stress
  • Blood Sugar problems
  • Brain Inflammation

Other factors to consider:

  • Mitochondria dysfunction
  • Oxygen deprivation
  • Brain immune health and Gut immune health – Brain/Gut Axis
  • Hormone imbalances
  • Inflammation in the body
  • Poor liver detoxification
  • Lack of Neurotransmitters

The brain needs these three things to be healthy:

  • Oxygen
  • Glucose
  • Stimulation

There are many interventions that can improve brain fog. These include Beemer, Hyperbaric oxygen therapy, nutrition, supporting detox, massage, restoring proper communication pathways, Grounding, controlling blood sugar imbalances, and managing cortisol. Supporting the body’s ability to get rid of bacteria, fungi and viruses is also critical.

That said, nutrition is perhaps the most significant determinant of brain health. Our standard American diet (SAD) and our culture’s acceptance of fake foods are wreaking havoc on our bodies and brains. Brain fog from inflammation is significantly worse when there is body inflammation and specifically intestinal inflammation from a leaky gut. An appropriate diet that reduces sugar and inflammation will go a long way to putting our fire in the brain and clearing away the fog.
