- Epilepsy and Progesterone
- </h1>
- <p>
- The length of the life-span, and of the period of youth or immaturity, is closely associated with the size
- of the brain, and the brain has a very high rate of metabolism. When something interferes with this very
- high metabolic rate, the consequences may be instantanteous,* or developmental, or chronic and degenerative,
- or even transgenerational. The issue of epilepsy centers on questions of brain metabolism, and so it has all
- of those dimensions.
- </p>
- <p>
- As I discuss the mechanisms known to predispose a person to epilepsy, I will emphasize the centrality of
- oxidative energy production, and show how "stroke," "stress," "hyperactivity," "dementia," and other brain
- syndromes are related to "epilepsy." (Similar processes are being studied in the heart and other tissues;
- eventually, we might have a general language that will make it easier to understand the parallels in the
- various kinds of "seizure" in any organ.)
- </p>
- <p>
- As an old term, "epilepsy" has aquired a burden of pseudoscientific ideas, covering old superstitions with
- an overlay of new superstitions. [Hereditary epilepsy has been discussed in countless textbooks and medical
- journals, but I think a much better case could be made for the inheritance of a tendency to offer stupid
- genetic explanations.] "Hereditary epilepsy" and "idiopathic epilepsy" are seriously pathogenic terms;
- "brain scar" sometimes has a factual basis, but most often the term is an evasion of understanding.
- </p>
-
- <p>
- As long as we realize that the essential meaning of the word is "something that grabs you," "epilepsy" is a
- convenient way to refer to a cluster of convulsive states, fainting spells, night-terrors and nightmares,
- and strange sensations.
- </p>
- <p>
- Seizures can be caused by lack of glucose, lack of oxygen, vitamin B6 deficiency, and magnesium deficiency.
- They are more likely to occur during the night, during puberty, premenstrually, during pregnancy, during the
- first year of life, and can be triggered by hyperventilation, running, strong emotions, or unusual sensory
- stimulation. Water retention and low sodium increase susceptibility to seizures. When I was in high school,
- our dog found and ate a pint of bacon grease, and shortly afterward had a convulsive seizure. I knew of
- veterinarians who treated seizures in dogs with a vermifuge, so it seemed obvious that a metabolic
- disturbance, especially if combined with intestinal irritation, could cause fits.
- </p>
- <p>
- It was undoubtedly such observations that led some physicians to advocate removal of the colon as treatment
- for epilepsy. Pregnancy and the menstrual cycle have been recognized as having something to do with
- seizures, but when seizures occurred only during pregnancy, they were classified as nonepileptic, and when
- they had a clear premenstrual occurrence, they were likely to be classified as "hysterical fits," to be
- treated with punishment.
- </p>
- <p>
- It has been observed that all "recognized" anti-seizure drugs are teratogenic, and women who are taking such
- drugs are told that pregnancy might kill them if they stop the drug, but that their babies will have a
- greatly increased risk of birth defects if they take the drugs during pregnancy. This is why a better
- understanding of epilepsy is very important. Old therapies are mainly important for the insight they can
- give into the nature of the physiological problem. Some of the well established clinical-laboratory
- observations (F. Mora, and C. S. Babel, for example) give strong hints as to the physiological problem, for
- example, low albumin, high prealbumin, low magnesium and high calcium all suggest hypothyroidism. (Problems
- with the bowel, liver, and sex hormones are highly associated with hypothyroidism, both as causes and as
- effects.) Water retention was so clearly involved in seizures that increased water intake was used as a
- diagnostic procedure. (R. Grinker) Unfortunately, animal experiments showed that water intoxication
- increased susceptibility to seizures even in normal individuals. Low sodium content in the body fluids also
- predisposed to seizures, so that someone with hyponatremia (low blood sodium) would be more susceptible to
- induction of a seizure by excessive water intake. (Excessive water uptake is still recognized as a factor in
- seizures, but now it is seen as part of a complex process, involving energy, hormones, and transmitter
- substances. E.g., Kempski; Chan.)
- </p>
- <p>
- Hypothyroid people tend to lose sodium easily, and unopposed estrogen increases water retention, without an
- equivalent sodium retention, so low thyroid, high estrogen people have two of the conditions (edema and
- hyponatremia) known to predispose to seizures. Another outstanding feature of seizures of various sorts is
- that they are most likely to occur at night, especially in the early pre-dawn hours. Low blood sugar and
- high adrenalin predominate during those hours. Hypoglycemia, in itself, like oxygen deprivation, is enough
- to cause convulsions.
- </p>
- <p>
- Progesterone and thyroid promote normal energy production, and their deficiency causes a tendency toward
- hypoglycemia, edema and instability of nerves.
- </p>
- <p>
- Twenty years ago, a woman who was considered demented visited me. From the age of 21, she had been
- increasingly disabled by premenstrual migraines. When she was 35 she was a school teacher, and during the
- summer a neurologist told her that dilantin would help her headaches, because "migraine is similar to
- epilepsy." Although she told the neurologist that the drug made her "too stupid to teach school," he offered
- her no alternatives, and didn't mention that sudden withdrawal from the drug could trigger a seizure. When
- classes started she discontinued the dilantin and had a seizure. The neurologist said the seizure proved
- that migraines were a form of epilepsy. At the age of 52, she spent about 20 hours a day in bed, and
- couldn't go outside by herself, because she would get lost. After using a little progesterone for a few
- days, she stopped having seizures, discontinued her drugs, and was able to work. When she returned to
- graduate school, she got straight As, and earned her masters' degree in gerontology. But she had lost 17
- years because the drug industry had covered up the role of the hormones in epilepsy, migraine, and the
- perimenstrual syndrome.
- </p>
-
- <p>
- The most popular anticonvulsant drugs are both neurotoxic and teratogenic, that is, they damage the
- patient's brain, and greatly increase the incidence of birth defects. The Nazis justified their horrible
- medical experiments as "science," but the effects of epilepsy medicine in the last half century have been
- similar in effect, grander in scale, and without any scientific justification.
- </p>
- <p>
- Besides the specific promotional efforts of the drug industry and their branch of government, there is a
- broader situation that makes their work easier. It is a culture of goony ideas, that ultimately emanates
- from the academic elite, which (since Descartes, and before) places "thought" above evidence. In biology,
- "genes" and "membranes" are confused ideas that are used to justify actions that aren't based on evidence.
- For the Nazis, "cultural degeneracy" was a medical-biological-political category based on that style of
- thinking. In the United States, "genes" for epilepsy, hyperactivity, language development, IQ, eclampsia,
- etc., are "found" at Harvard/MIT/Stan- ford/Yale/Univ. of California, etc., by an elite whose wits have been
- dulled by environmental deprivation, that is, by a lack of criticism.
- </p>
- <p>
- By manipulating the diet and environment, animals can be made more or less seizure-prone, and it happens
- that the changes that affect the brain affect all other organs, in ways that are now fairly well understood.
- Examining the cellular events associated with a seizure is useful for therapy and prevention of seizures,
- but the same methods are helpful for many other conditions. It is now clearly established that stress can
- cause brain damage, as well as other diseases. Now that our public health establishment has eliminated
- smoking from public places, maybe they can find a way to reduce stress and disease by removing morons from
- positions of power.
- </p>
- <p>
- Excitotoxicity, in its simplest sense, is the harmful cellular effect (death or injury) caused by an
- excitatory transmitter such as glutamate or aspartate acting on a cell whose energetic reserves aren't
- adequate to sustain the level of activity provoked by the transmitter. Once an excitotoxic state exists, the
- consequences of cell exhaustion can increase the likelihood that the condition will spread to other cells,
- since any excitation can trigger a complex of other excitatory processes. As calcium enters cells, potassium
- leaves, and enzymes are activated, producing free fatty acids (linoleic and arachidonic, for example) and
- prostaglandins, which activate other processes, including lipid peroxidation and free radical production.
- Protein kinase C (promoted by unsaturated fats and estrogen) facilitates the release of excitatory amino
- acids. (See J. W. Phillis and M. H. O'Regan, "Mechanisms of glutamate and aspartate release in the ischemic
- rat cerebral cortex," Br. Res. 730(1-2), 150-164, 1996.) Estrogen supports acetylcholine release, which
- leads to increased extracellular potassium and excitatory amino acids. (See R. B. Gibbs, et al., "Effects of
- estrogen on potassium-stimulated acetylcholine release in the hippocampus and overlying cortex of adult
- rats," Br. Res. 749(1), 143-146, 1997.)
- </p>
-
- <p>
- Estrogen also stimulates the production of free radicals. Calcium, free radicals, and unsaturated free fatty
- acids impair energy production, decreasing the ability to regulate potassium and calcium. The increased
- estrogen associated with seizures is associated with reduced serum calcium (Jacono and Robertson, 1987).
- Feedback self-stimulation of free radicals, free fatty acids, and prostaglandins create a bias toward
- increased excitation.
- </p>
- <p>
- Ammonia is produced by stimulated nerves, and normally its elimination helps to eliminate and control the
- excitotoxic amino acids, glutamate and aspartate. The production of urea consumes aspartic acid, converting
- it to fumaric acid, but this requires carbon dioxide, produced by normal mitochondrial function. A
- deficiency of carbon dioxide would reduce the delivery of oxygen to the brain by constricting blood vessels
- and changing hemoglobin's affinity for oxygen (limiting carbon dioxide production), and the failure to
- consume aspartate (in urea synthesis) and glutamate (as alpha-ketoglutarate) and aspartate (as oxaloacetate)
- in the Krebs cycle, means that as energy becomes deficient, excitation tends to be promoted. This helps to
- explain the fact that seizures can be induced by hypoxia. (Balloonists and mountain climbers at extremely
- high elevations have mentioned suffering from severe insomnia. The mechanisms of excitotoxicity are probably
- involved in other forms of insomnia, too.) Antioxidants help to control seizures, by reducing the excitatory
- contribution of free radicals and lipid peroxidation. Since excitation can promote the toxic forms of
- oxidation, many surprising substances turn out to have an "antioxidant" function. Magnesium, sodium
- (balancing calcium and potassium), thyroid and progesterone (increasing energy production), and in some
- situations, carbon dioxide. Aspirin, by inhibiting prostaglandin synthesis (and maybe other mechanisms)
- often lowers free radical production. Adenosine seems to have a variety of antioxidant functions, and one
- mechanism seems to be its function as an antiexcitatory transmitter. One of estrogen's excitant actions on
- the brain probably involves its antagonism to adenosine (Phillis and O'Regan, 1988).
- </p>
- <p>
- Albumin, besides maintaining blood volume and preventing edema, serves to protect respiration, by binding
- free fatty acids. Estrogen blocks the liver's ability to produce albumin, and increases the level of
- circulating free fatty acids. Free fatty acids cause brain edema. This is probably another aspect of
- estrogen's contribution to seizure susceptibility. Magnesium sulfate has been used for generations in India
- to treat eclampsia and "toxemia" of pregnancy, and its effectiveness is gradually coming to be recognized in
- the U.S. Increasingly, magnesium deficiency is recognized as a factor that increases susceptibility to
- seizures. (Valenzuela and Benardo, 1995; Slandley, et al., 1995). Hypothyroidism reduces the ability of
- cells to retain magnesium. Thyroid does many things to protect against seizures. It keeps estrogen and
- adrenal hormones low, and increases production of progesterone and pregnenolone. It facilitates retention of
- magnesium and of sodium, and prevents edema in a variety of ways.
- </p>
-
- <p>
- Progesterone, because of its normal anesthetic function (which prevents the pain of childbirth when its
- level is adequate), directly quiets nerves, and in this way suppresses many of the excitotoxic processes. It
- has direct effects on mitochondria, promoting energy production, and it facilitates thyroid hormone
- functions in various ways. It promotes the elimination of estrogen from tissues, and is a "diuretic" in
- several benign ways, that are compatible with maintenance of blood volume. It antagonizes the
- mineralocorticoids and the glucocorticoids, both of which promote seizures. (Roberts and Keith, 1995.) The
- combination of hypoglycemia with elevation of cortisone probably accounts for the nocturnal incidence of
- seizures.
- </p>
- <p>
- If progesterone's antiepileptic effectiveness were not enough (and it is very effective even in irrational
- pharmaceutical formulations), the fact that it reduces birth defects, and promotes brain development and
- nerve repair should assure its general use in women with a history of seizures, until it is established that
- they are no longer "epileptic." Although thyroid, progesterone, and a high quality protein diet will
- generally correct the epilepsy problem, it is important to mention that the involvement of unsaturated fats
- and free radicals in seizure physiology implies that we should minimize our consumption of the unsaturated
- fats. Even years after eliminating them from the diet, their release from tissue storage can prolong the
- problem, and during that time the use of vitamin E is likely to reduce the intensity and frequency of
- seizures. Coconut oil lowers the requirement for vitamin E, and reduces the toxicity of the unsaturated fats
- (see Cleland, et al.), favoring effective respiration and improving thyroid and progesterone production.
- Endotoxin formed in the bowel can block respiration and cause hormone imbalances contributing to instability
- of the nerves, so it is helpful to optimize bowel flora, for example with a carrot salad; a dressing of
- vinegar, coconut oil and olive oil, carried into the intestine by the carrot fiber, suppresses bacterial
- growth while stimulating healing of the wall of the intestine. The carrot salad improves the ratio of
- progesterone to estrogen and cortisol, and so is as appropriate for epilepsy as for premenstrual syndrome,
- insomnia, or arthritis.

- When the brain loses its oxygen supply, consciousness is lost immediately, before there is much decrease in
- the ATP concentration. This has led to the proposal of interesting "electronic" ideas of consciousness, but
- there is another way of viewing this. While ATP constitutes a kind of reservoir of cellular energy, the flow
- of carbon dioxide through the brain cell is almost the mirror image of the flow of oxygen. Oxygen scarcity
- leads directly to carbon dioxide scarcity. The "sensitive state," consciousness, might require the presence
- of carbon dioxide as well as ATP, to sustain a cooperative, semi-stable, state of the cytoplasmic proteins.
- The ability of ordinary light to trigger a conformation change in the hemoglobin-carbon monoxide-carbon
- dioxide system shows how sensitive a system with only a few elements can be. At the other extreme from
- consciousness, there is the evidence that carbon dioxide is essential for even the growing/living state of
- protozoa, algae, and bacteria.(O. Rahn, 1941.)

- to young as well as old cells." "...it is possible...to remove it as rapidly as it is produced, and under
