Five Depression Biotypes

Reprinted with permission from Brain World (Fall 2014)

Are all cases of depression the same? Dr. William Walsh thinks this is unlikely. After working with more than 30,000 patients, Dr. Walsh has identified specific chemical imbalances that lead to emotional and mental problems.  Out of his experiences, he identified five distinct biotypes from what was once lumped together as ‘clinical depression:’ undermethylation; folate deficiency; copper overload; pyrrole disorder; and toxic metals. He will be presenting on the five biotypes at the Restorative Medicine Conference in Tucson, AZ this fall.


Undermethylated depression
 arises from low activity at serotonin receptors due to rapid re-absorption after serotonin is released into a synapse.  This occurred in 38 percent of the patients he studied and is not serotonin deficiency, but an inability to retain the serotonin in the synapse for a necessary amount of time.  Patients usually report excellent improvement in mood with SSRIs, but for some, serious side effects such as headache or loss of libido can occur.  Nutrient therapy should avoid folates, but use SAMe- methionine.  Other nutrients such as zinc, serine, inositol, calcium-magnesium and vitamins A, B6, C, D and E can be supplemented as needed.

Symptoms and traits:  Strong willed, tendency toward obsessive-compulsive disorder, calm exterior with high inner tension, competitive and perfectionistic, addictive tendencies, high libido and more than 75 percent exhibit seasonal allergies.

Undermethylated people are the “classic depressives,” according to Walsh.  Highly depressed, but typically able to hide it; undermethylation tends to run in families.  About 20 percent of babies are undermethylated at birth.


High copper depression
 is marked by extreme levels of copper in the blood and brain, causing a dopamine deficiency and norepinephrine overload. Increased copper retention is necessary to rapidly produce capillaries and blood vessels for the growing fetus, and some mothers are unable to eliminate the excess copper.  Walsh suspects that postpartum depression is usually caused by copper overload.  Seventeen percent of the depression patients in the study fit this category.  Most reported little effect from taking SSRIs, but gained relief from embarking on nutrient therapy to normalize levels of copper.

Symptoms and traits:  More than 95 percent female with onset during hormonal event, high anxiety, tendency to panic, estrogen intolerance, tinnitus, sensitive skin, intolerance to cheap metals.
 

Pyroluric depression occurs when serotonin production is impaired and there is a high level of oxidative stress.  The production of pyrroles/ hydroxyhemopyrrolin can increase with stress, which in turn decreases zinc and B6 – nutrients that are essential for the production of neurotransmitters such as serotonin, melatonin, GABA, and acetylcholine.  SSRIs were advantageous for the 15 percent of the patients with pyroluric depression.  Nutrient therapy includes normalizing B6 and zinc, adding antioxidants, and augmenting with biotin and primrose oil.

Symptoms and traits:  Severe mood swings, extreme anxiety and fears, poor short-term memory and reading disorders, little to no dream recall, sensitivity to light and noise, abnormal fat distribution.


Low-folate depression
 is of critical importance, in that most of the shooters in some 50 school shootings over the past five decades likely had this type of depression, according to Walsh.  For these patients, taking SSRIs can lead to suicidal or homicide ideation.  Nutrient therapy using folic acid and vitamin B12 supplements helped patients in the study.  For some, anti-anxiety drugs (benzodiazepines) such as Xanax, Valium, Klonopin and Ativan were also beneficial.  Twenty percent of the patients in Walsh’s study fell into this category.

Symptoms and traits:  High tendency for anxiety and panic, non-competitive in sports and games, food and chemical sensitivities, high musical or artistic ability, underachievement, sleep disorders, absence of inhalant allergies, low libido, tend to be “people persons,” constantly talking.


Toxic metal depression
 is caused by toxic-metal overload—usually lead poisoning.  The removal of lead from paint and gasoline has lowered the frequency of these cases.  Walsh estimates that about 5 percent of depressed patients fall into this category.  Nutrient therapy concentrates on zinc, glutathione, selenium and other antioxidants – and calcium in the special case of lead poisoning.  In severe cases, hospitalization and chelation may be necessary.

Symptoms and traits:  Unrelenting depression, abdominal distress, tendency toward irritability and/or anger, absence of trauma or emotional triggers, food sensitivities, metallic taste in mouth, bad breath.

His book, Nutrient Power: Heal Your Biochemistry and Heal Your Brain describes the evidence-based nutrient therapy system.
