What Causes Schizophrenia?

In order to hopefully treat and prevent recurrence of schizophrenia we need to understand and — if possible — remove the underlying causes and risk factors.  We need to ask: "What else is going on inside the body that might allow schizophrenia symptoms to develop?"

Diagnose your symptoms now!
  • check your overall health status
  • learn what you should be doing right now
  • identify any nutritional deficiencies

Accurate diagnosis of the factors behind schizophrenia consists of three steps:

Step 1: List the Possible Causative Factors

Identify all disease conditions, lifestyle choices and environmental risk factors that can lead to schizophrenia symptoms.  Here are eight of many possibilities (more below):
  • Candida / Yeast*
  • Hypoglycemia*
  • Megaloblastic Anemia*
  • Lack Of Sleep*
  • Syphilis*
  • High Histamine*
  • Huntington's Disease*
  • Pyroluria*
* symptoms can be very similar

Step 2: Build a Symptom Checklist

Identify all possible symptoms and risk factors of each possible cause, and check the ones that apply:
fatigue after slight exertion
occasional confusion/disorientation
excess saliva in mouth
spacey/unreal feelings
very strong appetite
macrocytic red cells
difficulty swallowing
afternoon coffee/sugar craving
having excess body fat
being highly motivated
shoulder tightness
genital sores
... and more than 100 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of schizophrenia symptoms:
Cause Probability Status
Candida / Yeast** 97% Confirm
Pyroluria** 30% Unlikely
Syphilis** 21% Unlikely
Huntington's Disease** 5% Ruled out
High Histamine** 3% Ruled out
Megaloblastic Anemia** 0% Ruled out
Hypoglycemia** 0% Ruled out
Lack Of Sleep** 0% Ruled out
* This is a simple example to illustrate the process
** Symptoms can be very similar

Arriving at a Correct Diagnosis

The Analyst™ is our online diagnosis tool that learns all about you through a straightforward process of multi-level questioning, providing diagnosis at the end.

If you indicate unusual mental conditions/symptoms, The Analyst™ will ask further questions including this one:
Have you been diagnosed with or suspected of having Schizophrenia or schizophrenic tendencies?
Possible responses:
→ No / never
→ It has been hinted at only
→ Yes, a significant problem, but in the past only
→ Yes, it is a chronic but minor problem
→ Yes, it is a chronic and serious problem
Based on your response to this question, which may indicate possible schizophrenia, history of schizophrenia, schizophrenia or severe schizophrenia, The Analyst™ will consider possibilities such as:
Acute, Intermittent Porphyria

A review of 2,500 psychiatric patients showed a 1.5% occurrence of porphyria.

Allergy to Foods (Hidden)

An allergy is a negative sensitivity to a substance which causes a physical reaction.  Classical responses include creation of blood antibodies, histamine release, swelling, itching, runny nose, and others.  However, various substances can cause negative reactions that are not commonly associated with allergies.  In the case of cerebral (brain) allergies (which affect the nervous system), reactions include brain inflammation, irritability, fear, depression, aggression, extreme mood swings in a single day, hyperactivity, and psychosis.  These symptoms can be mistaken for schizophrenia.

A study of "schizophrenics" by Dr. William Philpott showed allergic responses as follows: Wheat (64%), mature corn (51%), pasteurized whole cow's milk (50%), tobacco (75% with 10% becoming grossly psychotic with delusions, hallucinations and particularly paranoia), and hydrocarbons (30% with weakness being common and some participants reacting with delusions or suicidal inclinations).  92% of the patients showed allergic responses with an average of ten items per person causing reactions.

Gluten Sensitivity / Celiac Disease

Studies have shown celiac disease to be inordinately high in "schizophrenic" populations.  Research removing gluten and dairy products (which often seems to add to the problem) from the diet of a locked ward resulted in a significant improvement of patient behavior.

Histadelia (Histamine High)

Some 15-20% of "schizophrenic" patients are in fact suffering from histadelia, which shares similar symptoms and can be misdiagnosed.

Histapenia (Histamine Low)

It has been found that 50% of patients classified as "schizophrenic" have low histamine levels in the blood and it rises to normal as they improve.  These same patients are found to have high copper levels.  Elevated copper decreases blood histamine.  Excess copper is linked with psychosis.  People with histapenia tend to have classic signs of schizophrenia, including canker sores, difficult orgasm with sex, no headaches or allergies, heavy growth of body hair, ideas of grandeur, undue suspicion of people, racing thoughts, the feeling that someone controls one's mind, seeing or hearing things abnormally, ringing in the ears, and others.

Huntington's Disease

Commonly labeled as "schizophrenia" because of its progression of mental decline.


Numerous patients given psychiatric diagnoses have actually turned out to have hypoglycemia, including those classified with depression, manic-depressive disorder, and schizophrenia.


The book Natural Healing for Schizophrenia reports that 10% of patients diagnosed with "schizophrenia" have been found to have thyroid imbalances.

Lack of Sleep

In extreme stages bizarre behavior and hallucinations can arise from lack of sleep.

Megaloblastic Anemia / Pernicious Anemia

Additional mental disturbances resulting from pernicious anemia include: loss of alertness, drive, self-confidence, and independence, social withdrawal, nervous irritability, headaches, insomnia, moodiness, severe agitation, lack of coordination, anxiety, delusions of persecution, and mania.  Deficiency may also induce auditory hallucinations, psychosis, and paranoia.  80% of pernicious anemia patients show neurological changes and 60% exhibit personality changes.


Abnormal production of pyrroles and their appearance in the urine of psychotics was first noticed in 1958 during LSD experimentation.  Approximately 15-30% of "schizophrenics" have pyroluria.  (At least 10% of these also have histamine problems.)

Seizure Disorder

Not all seizures are jerking motions.  In psychomotor (mind-motion) epilepsy the seizures are manifested in personality, emotional, thinking, and behavioral changes.  This condition is very likely to be misdiagnosed as a mental disorder.  People with psychomotor epilepsy have been given schizophrenia, manic depressive, depression, attention-deficit disorder, and other diagnoses.

STD Syphilis

Dementia paralytica, or paresis, is a form of syphilis which generally affects patients in their 40s or 50s.  Increased behavioral deterioration occurs and the person may be believed to have a "psychiatric illness" or Alzheimer's disease.  Symptoms can include convulsions, irritability, difficulty in concentrating, deterioration of memory, defective judgment, headaches, insomnia, fatigue, lethargy, deteriorated hygiene emotional instability, depression, and delusions of grandeur with lack of insight.  The patient gradually progresses toward dementia and paralysis.

Vitamin B3 Requirement

The mental disturbances brought about by pellagra, a vitamin B3 (niacin) deficiency may be mistaken for schizophrenia, or vice versa.  The symptoms of schizophrenia and pellagra so closely resemble each other that is it extremely difficult to tell them apart.

Wilson's Disease

A wide array of symptoms occur, fitting a number of psychiatric diagnoses, including "major depression," "schizophrenia," and "hysteria."  Children with Wilson's disease can appear to be mentally retarded.  Appetite loss and weight loss can appear along with hallucinations and delusions.  The physical manifestations of Wilson's disease do not appear until the late stages, thus it is easily misdiagnosed as "psychiatric illness."

Yeast / Candida Infection

Although psychosis is not a common manifestation of Candida, it has occurred.  Mental symptoms have included fatigue, inability to concentrate, depression, mood swings, anxiety, hyperactivity, delusions, "manic depression," psychosis, and suicidal or violent tendencies.
