Human brain symptoms and conditions

I am 39 years old and work for an interventional cardiology medical device company in Tokyo, and so know the importance of controling one's cholesterol, keeping the LDL's low and the HDL's high. About two years ago, my doctor put me on 10 mg of Lipitor. Several months later I herniated a disc in my neck between C6&C7. From that point onward, I attributed all of my neck and back pain, and newly acquired total body muscle and joint pain, to the herniated disc, it made the most sense. Over the last seven months, I have really worked on my diet and began to exercise more (even though quite painful) and was able to lower my cholesterol. This resulted in my doctor lowering my Lipitor prescription from 10 mg to 5 mg. I noticed a slight alleviation of the pain I felt in my hip joints and calves. About two weeks ago I took myself off Lipitor completely and found further improvements in my total body muscle and joint pain. It's still there but greatly improved. In retrospect, I now believe the Lipitor may have been the culprit (or at least a contributing factor) to my herniated disc due to muscle degeneration in the neck, and all of the subsequent muscle pain, especially in my hips and calves. I fully understand I am not going to die from calf-pain, but may from heart disease. However, I have found my quality of life has improved tremendously over the last few weeks. Less irritability, better sleep, less pain, clearer head. I feel like I have lost two years of my life on Lipitor via personal suffering and lack of ability to do much of anything with my wife and two young daughters. We all need to take charge of our own health and therefore I encourage anyone who feels completely different after taking Lipitor to engage your physician, and make sure its the right option for you. If damage has been done to my musculature I hope I can reverse it. It is evident to me that some serious clinical studies should be done to investigate Lipitor's effect on muscle degradation and hope others will consider carefully whether or not do go on this drug. If you do, monitor yourself closely.

Dizziness, back ache, severe hip and shoulder pain, transient global amnesia, after discontinued taking of Lipitor, speech problems, loss of words.

I am a 52 year old female and my bad cholesterol is fine but my good cholesterol is low. I have been taking Lipitor now for a few years and have numb hands and feet to the elbows and knees. My feet are extremely sensitive, worse at night and now I'm getting sharp pains that feel like a bug just bit me. My tongue is also always numb and I do get migraines.I have insane stomach issues and food intolerance. I also take medication for high blood pressure, acid reflux, & thyroid. I have now been diagnosed with type 2 Diabetes but control that with diet so far. Until four years ago I had nothing wrong with me. I am slim and healthy. I had a lump in my thyroid which was removed and there was a trace of cancer. Then like dominos all the other conditions lined up. I have had MRIs and all the tests and doctors insist that I am not a severe enough diabetic to have neuropathy. I can hardly wear shoes now and it hurts when I wear runners while I walk and exercise. Does any of this sound familiar to anyone? I hate that my health has become so much a part of my daily life. Does anyone have neuropathy as a result of Lipitor and am I even taking the the right medication since I don't have high cholesterol?

I have stopped taking Lipitor after 3 yrs. I was told I had a mini-stroke because of my slurred speech 6 mo. ago. Since then I have had a battery of tests and my neurologist told me "I don't think you had a stroke." I saw the words "Motor Neuron Disease" (I looked it on the web because I never heard of it before) on the script for my EMG. I blame it all on Lipitor and the wasting of the nerves and the muscles. I sound as if I am drunk. No one can understand me . I am taking speech therapy but it doesn't seem to help.

My mother is 74 and has been on Lipitor 5 mg for about 6 weeks now and has experienced her 1st TGA. She called me today to tell me that someone had come into her house and cooked a platter of bacon and moved a basket around. She couldn't find her purse and went outside and sure enough it was in her car, but the door was standing wide open and the purse was sitting on the seat. She remembers nothing! This evening she swore that our second child was born in a different house. This from a woman who can remember the tiniest minutia. This Lipitor is terrible stuff! She is now officially off of it.

Neurological problems and the effects of Singulair should be investigated. The Chinese researchers demonstrated that the CysLT1 receptor (singulair inhibits this receptor) does exist in the human brain. In the rat brain, they demonstrated that there is a link between this receptor and the astrocyte.

There are many researchers/doctors interested in excitotoxicity and damage to neurons.

I would like to know how Singulair affects the astrocyte numbers and function. I would also like to know if there is a link between metabolism and the cysLT1 receptors in gastro-intestinal mucosa. Does Singulair affect the metabolic process?

So many parents are complaining of ADD/ADHD symptoms? The paper that I gave you the link correlates the immune response and excitotoxicity. That is very interesting. How many asthma and allergy patients also suffer from potential excitotoxicity? Does Singulair cause it in some patients or just make it worse in some patients? None the less--there is a possible link.

Is there a potential explanation for the adverse psychiatric side effects of montelukast?

In my opinion, there are at least some very good clues based upon the work of the Chinese researchers.

A 2006 report indicated that they had localized (meaning found it was there) the CystLT1 receptor (same as the receptor that montelukast
Singulair blocks) in the neurons of the brain tissue of rats. In order to do that, they injected rat brain's with NMDA to cause a chemically induced state of excitotoxicity. Excitotoxicity is a common factor in Central Nervous System disease. They concluded that both 5-LOX and CystLT1 were upregulated by the excitotoxicity that they artificially created
with the NMDA. Therefore, there would be a potential link between neuron activity and CystLT1. Nerve cells are damaged by excitotoxicity. These researchers used NMDA to cause nerve damage which caused the CystLT1 to show up. NMDA was often used in human behavior studies to cause brain damage. They would then try to observe whether behavior was compromised to conclude what areas of the brain determined what behavioral response.

So I was thinking about the Chinese researchers as I was reading other posts. One post interested me particularly regarding the mother who described behavior that seemed like hypoglycemics when their snack doesn't arrive on time. So a light bulb went on. Glutamate, another excitotoxin, can build up in the brain to a level that is damaging if humans become excessively hypoglycemic. If glutamate concentration around the synaptic cleft reaches too high a level then neurons die. Clinically, it really does seem that many people experience things that sound like the effects of hypoglycemia. It could be only a coincidence. But then again, maybe not.

The Chinese researchers found the CystLT1 receptor in the rat brain neuron after brain damage. They found the CystLT1 receptor in the normal human brain in the microvascular endothelial cells and in neuron and glial-appearing cells in brain trauma or tumors.

What role does the CystLT1 play in brain function? If it exists in brain tissue, we can assume that it does have a function. If it plays a role in preventing or repairing neuron damage due to excitotoxins, then there would be a very direct link between Singulair and adverse psychiatric side effects.

The bottom line is that Merck owes people who take Singulair further research regarding it's effect on the brain.
