Folinic Acid for Autism – FRAT Testing
Leucovorin for Autism: What Parents and Clinicians Should Know Families and clinicians are exploring whether folate receptor autoantibodies (FRα) contribute to low brain folate-and when folinic acid (leucovorin) may help. This article explains FRAT testing, what the evidence shows, and how we personalize decisions at Second Opinion Physician. What Are Folate Receptor Antibodies? FRα transports […]

Understanding the Methylation Test
How to Read a Methylation Panel Report: SAM, SAH, Homocysteine and Nutrient Needs Learning how to read a methylation panel report begins with understanding that the test measures current biochemistry-not merely genetic potential. Functional panels from Genova Diagnostics and Doctor’s Data evaluate metabolites such as methionine, SAM, SAH, homocysteine, cystathionine and cysteine, while the broader […]

Trauma, TBI, & Hormones – Mark Gordon, MD
The Mark Gordon Approach to Traumatic Brain Injury: Hormones, Neuro-Inflammation, Biomarkers and Peptides Dr. Mark Gordon’s approach to traumatic brain injury and post-concussion syndrome focuses on the biochemical consequences that may persist after a concussion, blast exposure or repetitive head trauma. Rather than viewing depression, fatigue, insomnia, irritability, cognitive decline and PTSD-like symptoms only as […]

Insomnia
Insomnia Causes and Treatment: Types of Insomnia, Medication Side Effects, Cortisol and Walsh Biotypes Insomnia causes and treatment vary because difficulty falling asleep, repeated awakenings, early-morning waking and nonrestorative sleep do not arise from one mechanism. The main types of insomnia may reflect hyperarousal, cortisol and glucose dysregulation, trauma, medication effects, intestinal problems or circadian […]

Alkaline Diet and Kidney Function
Alkaline Diet, Body pH and Kidney Function: How Acid Load May Affect Filtration and Methylation An alkaline-forming diet does not directly change blood pH, which is tightly regulated by the lungs and kidneys. It can, however, reduce dietary acid load and increase the supply of potassium, magnesium, citrate and bicarbonate precursors used for buffering. In […]

How Toxic Overload Causes Mood Disorders
Can Toxic Overload Cause Depression? Elevated SAH, Glutathione and Undermethylation Toxic overload and depression may be connected when environmental exposures, gut-derived toxins, oxidative stress, glutathione depletion and impaired clearance reduce neurological resilience. In susceptible patients, these pressures may increase mitochondrial stress, raise SAH, lower the SAM-to-SAH ratio and create a functional undermethylation pattern that contributes […]

Liver Detoxification Pathways: Phases, Glutathione and Bile
Liver Detoxification Pathways: How Methylation, Glutathione and Bile Remove Toxins The liver transforms medications, alcohol, hormones, environmental chemicals, microbial products and metabolic waste so they can be eliminated through urine or bile. These liver detoxification pathways depend on coordinated Phase I transformation, Phase II conjugation and Phase III transport, together with adequate methylation, homocysteine metabolism, […]

Kidney Detoxification, Elevated SAH and Methylation
How Kidney Detoxification May Improve Methylation The kidneys do far more than filter blood. They regulate acid-base balance, electrolytes and the removal of metabolic waste that can interfere with methylation. When kidney filtration, buffering capacity or downstream disposal is impaired, SAH, homocysteine and adenosine may accumulate, slowing methylation and contributing to fatigue, inflammation and toxic […]

Five Epigenetic Biotypes of Undermethylation | Beyond MTHFR
The Five Epigenetic Biotypes of Undermethylation Dr. William Walsh identified five major biochemical biotypes associated with mood and behavior disorders: undermethylation, overmethylation, copper overload, pyroluria and toxic overload. Toxic overload-the fifth Walsh biotype-can inhibit methylation through elevated SAH and impaired SAH-hydrolase pathway function, ultimately contributing to an undermethylated state. The Five Epigenetic Biotypes of Undermethylation […]

Walsh Toxic Overload Biotype: Elevated SAH, Zinc and the SAHH Bottleneck
Elevated SAH, Zinc and the SAH Hydrolase Pathway Dr. William Walsh’s interpretation of elevated SAH centers on a bottleneck at the SAH hydrolase (SAHH) pathway. SAH is reversibly connected to homocysteine and adenosine, so the pathway does not continue moving away from SAH unless both downstream products are adequately processed. In the Walsh model, zinc […]
