The Facts About Glutathione and Parkinson's Disease
by: Priya Shah
Parkinson's Disease (PD), a
devastating illness, occurs in one of every 100 people over 65.
It is a slowly progressing disease
of the nervous system that results in progressive destruction of
brain cells (neurons) in an area of the brain called the substantia
nigra. Death occurs usually as a result of secondary complications
such as infection.
One of the mechanisms known to
destroy neurons is damage by free radicals or reactive oxygen
species - destructive molecules produced by oxidation of the
neurotransmitter dopamine.
The Role of Dopamine
The cells of the substantia nigra
use dopamine - a chemical messenger between brain or nerve cells -
to communicate with cells in another region of the brain called the
striatum.
When nigral cells are lost, nigral
dopamine levels fall, resulting in a decrease in striatal dopamine.
The typical symptoms of PD - motor
function deficiencies characterized by muscle rigidity, jerky
movements, rhythmic resting tremors - are the result of low levels
of striatal dopamine.
Most dopaminergic drugs used to
treat PD, are aimed at temporarily replenishing or mimicking
dopamine. They improve some symptoms, but do not restore normal
brain function nor halt brain cell destruction.
Dopaminergic drugs are generally
effective at first in reducing many PD symptoms, but over time they
lose their effect.
They also cause severe side effects
because they overstimulate nerve cells elsewhere in the body and
cause confusion, hallucinations, nausea and fluctuations in the
movement of limbs.
The Role of Antioxidants
When dopaminergic neurons are lost
in the course of Parkinson's disease, the metabolism of dopamine is
increased - which in turn increases the formation of highly
neurotoxic hydroxyl radicals.
The most important free radical
scavenger in the cells of the substantia nigra is the powerful brain
antioxidant, glutathione. Glutathione levels in PD patients are low.
And as we age, levels of
glutathione in the dopaminergic neurons of the substantia nigra
decreases. This appears to hasten cell death and advance the
progression of PD.
At least 80 percent of the
substantia nigra cells are lost before symptoms of Parkinson's
disease become apparent. This is why it becomes essential to protect
or maintain these cells under oxidative stress.
How does Glutathione help in
Parkinson's Disease?
Several factors explain why
glutathione is so beneficial in Parkinson’s disease.
1. Glutathione increases the
sensitivity of the brain to dopamine. So although glutathione
doesn't raise dopamine levels, it allows the dopamine in the brain
to be more effective.
2. Glutathione's powerful
antioxidant activity protects the brain from free radical damage.
3. An even more intriguing benefit
of glutathione lies in its powerful detoxification ability.
Its a well known fact that most
Parkinson’s patients are deficient in their ability to detoxify
chemicals to which they are exposed.
The unfortunate few who harbor an
inherited flaw in their detoxification pathways are at far greater
risk to the brain damaging effects of a wide variety of toxins.
Glutathione is one of the most
important components of the liver’s detoxification system.
Glutathione therapy is one of the most effective techniques for
enhancing liver and brain detoxification.
Glutathione treatments considerably
improve some of the symptoms of Parkinson's disease including
difficulties with rigidity, walking, movement, coordination and
speech. A marked reduction of tremor has been observed as well as a
decrease in depression.
Glutathione and N-acetyl-L-cysteine
(a glutathione precursor) have been shown to be very effective in
protecting the nerves in the substantia nigra from being destroyed
by oxidative stress.
Glutathione Therapy in Parkinson's
Disease
The practical problem in increasing
glutathione levels is that taking glutathione itself as a supplement
does not boost cellular glutathione levels, since glutathione breaks
down in the digestive tract before it reaches the cells.
However, intravenous glutathione
therapy and taking glutathione precursors are both effective in
boosting intracellular levels of glutathione.
Intravenous Glutathione Therapy:
Intravenous glutathione injections
have been shown to have amazing and quick results.
Dr. David Perlmutter, a pioneer in
this therapy, has developed a protocol utilized at the Perlmutter
Health Center for administering intravenous glutathione to
Parkinson's patients.
Following even a single dosage of
intravenous glutathione - often in as little as 15 minutes - the
ability to walk, turn around and move their arms is almost
completely restored.
Glutathione Precursors:
Dietary antioxidants and
supplements that increase cellular glutathione, such as alpha lipoic
acid, NAC, pycnogenol, the herb silymarin (milk thistle), are
effective in restoring normal function.
N-acetyl-cysteine (NAC) and
un-denatured, whey protein both supply glutathione precursors
intracellularly, enhance the body’s production of glutathione and
aid the detoxification process.
Other nutritional supplements which
aid the detoxification process include selenium, vitamins E and C.
