Two human figures made of glowing wires and neor representing Norepinephrine and methylation. Norepinephrine is both a neurotransmitter in the brain and a hormone in the body, and more importantly, symptoms of low or high norepinephrine could tell us something about methylation patterns.

In clinical practice, however, patterns often emerge before the research fully catches up. One such pattern I observe is a striking overlap between individuals with MTHFR gene variants and symptoms of ADHD or ADD. To be clear: this is not yet a fully established causal relationship. But there is enough emerging evidence—and strong biochemical plausibility—to warrant a closer look.

Brain fog is a frustrating symptom that many people experience without fully understanding its causes. It often feels like a cloud over your thinking, making it hard to focus, remember details, or process information clearly. One key factor linked to brain fog is blood sugar instability. When blood sugar levels swing too high or too low, the brain struggles to function optimally. Another important piece of this puzzle is the MTHFR gene variance, which can influence how the bo

Brain fog makes all of life more difficult because normal tasks become an uphill battle of hazy focus, forgotten pieces, and slow or stalled thought processes. The connection between MTHFR (methylenetetrahydrofolate reductase), blood sugar changes, and brain fog can help you beat this symptom for good.

Glycemic index sounds highly unsexy, which is fair, but it's actually a diet hack that can help you to keep your blood sugars balanced with very little work. You don't even need to know the exact glycemic index of a particular food to understand how to use this system.

Stress, sleep changes, medications, blood sugar imbalances and even genetics can contribute to brain fog. As a result, you may experience confusion, memory problems, and difficulty concentrating. Fortunately, many of the contributing factors to brian fog are under your control, and you can fix them if you know the steps.
