Mechanisms of action for Lithium include:
1. Stabilization of the inactive conformation of G-Protein
2. Inhibition of Adenylate Cyclase
3. Up-regulation of some Adenylate Cyclase subtypes
4. Uncompetitive inhibition of inositol-1-phosphatase - leading to a reduction in neuronal myo-inositol levels.
5. Supressing the phophatidyl inositol pathway
6. Reduction of Protein Kinase C activity by down-regulating selective PKC isozymes
7. Reducing intracellular calcium levels via the intracellular signaling pathways - leading to the regulation of synthesis and release of neurotransmitters, neuronal excitability, cytoskeletal remodeling, and neuroplasticity
8. Reduction in the turnover rate of archidonic Acid (part of the omega-6 fatty acid pathway)
9. Down-regulation of arachidonic acid-specific phospholipase A12 protein
10. Inhibition of glycogen synthase kinase-3 by competing with magnesium for a binding site
11. Increase in the Extracellular Signal-Related Kinase signaling pathway activity (such as in the frontal cortex and hippocampus).
12. etc., etc.

Which ones are most important for pharmacologic function is not clear - though the sum total is probably the case - which each patient having individual differences in response.

Lithium is NOT a natural part of the body. Excessive doses, such as in the 1950s when cardiologists thought it would make a good salt substitute, led to cardiac arrhythmias, confusional states, and deaths.

Lithium has interactions with common medications such as Ibuprofen and other Non-steroidal Antiinflammatory Agents - which block the excretion of lithium in the kidneys, leading to sometimes excessive concentrations in the blood.

Lithium is unique medication in that the effective dose is extremely close to the toxic and lethal dose. It is thus not a medication to play with. More is not necessarily better because it may also be fatal. The physician has to be highly careful with its use.
Hi Marianco, Are we to understand that high levels of myo-inositol can lead to anxiety states? I've always thought that we can take supplemental myo-inositol to reduce anxiety levels? Appreciate any comments. Greg B.

Is Akathisia more psychological like anxiety, or more physical like parkinsons?
I think I might of had it before, is loss of apetite and inability to keep food down one of the symptoms?

Then, I ask if it's possible (Over the las 3 weeks) that because of the hCG (Possible raise in E2) is causing panic attacks? Both have no idea.

Any advice on these 2 issues?
I can't give you advice since you are not a patient.

However, I can give educational information about HCG (Chorionic Gonadotropin).

The issue of HCG and panic attacks is much more complex than what appears on the surface.

A partial account of the metabolic cascades involved is as follows:

HCG acts like LH (Luteinizing Hormone).

LH has several actions, such as:
1. It stimulates testosterone production from the testes
2. It stimulates the production of aromatase enzyme
3. It stimulates the production of Cytochrome P450sc enzyme
4. etc.

Testosterone has several actions, such as:
1. Increasing dopamine production in the brain.
2. Increasing OR Decreasing Thyroid hormone production.
3. Reducing ACTH production.
4. Directly reducing Adrenal hormone production.
5. Becomes Estradiol via Aromatase enzyme.
6. Becomes DHT (Dyhydrotestosterone) via 5-Alpha-Reductase enzyme
7. Promotes insulin sensitivity.
8. Has antiinflammatory signaling functions.
9. Excessive Testosterone can result in an increase in anxiety depending on the metabolic cascades involved.
10. etc.

Aromatase Enzyme:
1. Turns Testosterone into Estradiol
2. etc.

Cytochrome P450sc enzyme:
1. Turns Cholesterol into Pregnenolone
2. etc.

Estradiol (and other estrogens) has multiple actions, including:
1. Acting as a Monoamine Oxidase Inhibitor in the brain
2. Reducing thyroid hormone activity by increasing production of Thyroid Binding Globulin from the liver.
3. etc.

Monoamine Oxidase Inhibitors (such as Estradiol) to varying extents:
1. Increase Serotonin levels
2. Increase Norepinephrine levels
3. Increase Dopamine levels
4. etc.

Serotonin:
1. Reduces the perception of stress - thus has an antianxiety effect.
2. Reduces norepinephrine production from norepinephrine neurons - contributing to its antianxiety effect.
3. Reduces dopamine production from dopamine neurons - if reduced excessively, this can increase anxiety
4. Has antiinflammatory signaling functions
5. etc.

Norepinephrine:
1. Is the primary signal for stress
2. Excessive Norepinephrine can result in anxiety or irritability/anger.
3. Has inflammatory signaling functions.
4. Can increase energy by promoting adrenal hormone production - if the adrenal glands are not fatigued excessively
5. etc.

Dopamine:
1. Promotes a sense of well-being, calmness
2. Deficiency in Dopamine production can cause agitation or anxiety, etc.
3. etc.

Thyroid hormone:
1. Promotes energy production, such as by increasing mitochondria production and thermogenesis.
2. Promotes steroid hormone production - increasing testosterone production - thus lowering thyroid hormone can reduce testosterone production.
3. Promotes IGF-1 production - which does most of the actions of growth hormone
4. Increases serotonine production
5. Promotes insulin sensitivity
6. Has antiinflammatory signaling functions
7. Deficiency in Thyroid hormone can result in anxiety or irritability/anger
8. etc.

Growth hormone/IGF-1 hormone:
1. Can promote a sense of calm and well-being - deficiency of which can result in a higher level of anxiety.
2. Has antiinflammatory signaling functions.
3. etc.

Adrenal Hormone production, includes:
1. Cortisol
2. DHEA
3. Progesterone
4. Testosterone
5. Pregnenolone
6. Adrenal cortex hormone production - particularly Cortisol - promotes energy production
7. etc.

Cortisol:
1. Promotes energy - via gluconeogenesis, etc.
2. Feeds back to the brain to reduce Norepinephrine production - resulting in reduction in anxiety.
3. Deficiency in Cortisol production can result in anxiety
4. etc.

DHEA:
1. Increases Dopamine production in the brain
2. Promotes insulin sensitivity
4. Has antiinflammatory signaling functions
5. Deficiency of DHEA can result in anxiety.
6. etc.

Pregnenolone:
1. Has a stimulant effect.
2. Excessive Pregnenolone production can result in agitation, tension, or anxiety.
3. etc.

Progesterone:
1. Has a calming, mood-stabilizing effect.
2. Deficiency in Progesterone can result in agitation, tension, or anxiety.
3. Has antiinflammatory signaling functions.
4. etc.

Insulin:
1. Excess insulin can reduce testosterone production.
2. Has pro-inflammatory signaling functions.
3. etc. etc. etc.

Immune System:
1. Deficient antiinflammatory signaling may promote anxiety
2. etc. etc.

Nutrition:
1. Certain nutrients are necessary to promote function across the nervous system, endocrine system, and immune system.
2. Deficiency of certain nutrients can promote anxiety in response to HCG as a result of dysfunction in these systems.

Thus, when HCG causes anxiety, the story is actually more complex than just the resulting increase in Estradiol.
1. If HCG increases Testosterone excessively, it can cause a cascade that results in anxiety - e.g. by decreasing thyroid function, decreasing adrenal hormone production, etc - particularly if a person is predisposed to anxiety such as by having hypothyroidism and adrenal fatigue.
2. If HCG increases Estradiol, it can cause a cascade that results in anxiety IF (a big if), Estradiol increases norepinephrine more than serotonin and dopamine, or if it results in significant thyroid hormone reduction (particularly if a person is hypothyroid and has adrenal fatigue).
3. etc. etc. etc.

The solution would involve examining all the involved systems and chemical messengers (neurotransmitters, hormones, etc) rather than just knee-jerk blaming only estrogen and attempting to reduce estrogen levels. The solution involves addressing the problems that are actually present (e.g. hypothyroidism, adrenal fatigue, excessive insulin, etc.) to reduce the risk of anxiety with HCG particularly when one wants to use HCG to preserve testicular size or to use HCG as a replacement for testosterone replacement therapy.

Reducing estrogen levels blindly can increase the risk of multiple problems including anxiety itself - such as when estradiol more strongly increases serotonin than norepinephrine in a person.

Lab tests and an exam would be necessary to help determine where the problem lies. Then solving the problem would not involve so much trial-and-error and guesswork.

Yes, HCG can cause panic attacks in susceptible persons depending on the functioning of the nervous system, endocrine system, and immune system - the sum of which I call 'the mind".

thanks again for such a thorough response. Is there a directionality of neurotransmitters to hormones? Do the neurotransmitters control the hormones?

It is a web of interactions.

Neurotransmitters can control hormones and immune system cytokines.
Hormones can control neurotransmitters and immune system cytokines.
Immune System Cytokines can control neurotransmitters and hormones.

From my point of view, there is actually no difference between a neurotransmitter, hormone, and immune system cytokine. All are chemical messengers of the mind. And the mind is the sum function of the nervous system, endocrine system, and immune system.

Parkinson's disease is both a physical and mental illness. The mental symptoms of Parkinson's Disease often start much earlier than the physical symptoms. They include depressed mood, lack of motivation, impaired visuospatial thinking, impaired memory, anxiety, impaired concentration, etc. On neuropsychological testing, the impaired visuospatial thinking is most prominent in Parkinson's disease compared to other causes of dementia.

Similarly, akathisia is both a physical and mental condition. It is foremost considered a motor movement disorder just as Parkinson's disease is.

Symptoms of akathisia generally do not include loss of appetite or nausea and vomiting.

If a person has excessive copper similar to wilsons disease but its resulting from imparied adrenals would this build up of copper cause a possbile scenerio similar to estrogen domaince? I research alot of information and elevated histmaines keeps coming back up and only reason I can pin point this is due to an intestinal infection unresolved or that copper is building up in the tissue and causing a defiency in the blood resulting in a DOA deficeincy (enzyme that breaks down histmaines and serotonin) So can estrogen domiance leas into also a decreae of 5hiaa, gaba via urine and posible increases in shbg in the blood. If one is taking cortisol (via salvia testing) and not taking the appropiate dhea could you recieve the benefits from the cortisol, but since you lacking DHEA could the catabolic effects of cortisol be more pronounced (immune suppression, muscle wasting, ect)

Ad to that low homocysteine levels (3.9), low uric acid, low testosterone, low free t, and double normal shbg, low moly on hair, low copper, low ceruoplasm, elevated taurine, sarcosine, all low essential amino acids on urine test.

Epinephrine and Norepinephrine are secreted here. As you remember from Biology
1611, they can be regarded as neurotransmitters (e.g., depolarizing postsynaptic
membranes) or hormones. Normally, both are metabotropic; that is, they increase
the metabolism of many cells including heart and neural cells. NE causes generalized
vasoconstriction to increase blood pressure.NE and Ep cause vasodilation in the heart
and lungs - sympathetic functions. They vasoconstrict in the gut and slow digestion.
Is this a sympathetic function? Ep and NEp are fast acting in the flight/fight response.

The claim that MAOIs work primarily via serotonin is untrue. All expert psychopharmacologists know that irreversible MAOIs such as Parnate, Marplan, Nardil and high dose selegiline target both MAO-A and MAO-B neurotransmitters. Thats a whole lot more than just serotonin. MAOIs are "triple neurotransmitter antidepressants," plus some.
