Brain tumors symptoms and conditions

I have been through 5 cycles of IVF treatments all taking Lupron shots. The last cycle was 3 years ago. Lately, within the past 1-2 years, I have been very forgetful with names, forgetting where I'm driving to, in the middle of conversations, etc. And I also have knee pain but I'm not sure if maybe that is a result of working out too much at the gym. I am concerned with the constant forgetfulness and possible other side effects as I get older. I am now 42. While I was taking Lupron all that time, I have to say that I felt pretty good, aside from the small headaches from time to time. It basically stops your cycle. I do feel bad for those women who have had worse side effects. And I do question whether it ever leaves your body and if other side effects could be brain tumors (I heard that somewhere). Any insight would be appreciated. Good luck to all.

(I posted this before but after receiving some e-mail, I have revised a few sentences to hopefully make it more understable. )

I would like to share this information with everyone. First, I would like to caution all that it does not prove anything regarding the negative side effect of Singulair but it does suggest that there might (only might) be a physiological cause for any side effect that could be attributed to brain function. A Chinese team has been studying the receptor (Cysteinyl leukotrienes receptor 1) that is targeted by Singulair and is responsible for the method of action that makes Singulair successful. Here is one of their studies.

Links Expression of cysteinyl leukotriene receptor 1 in human traumatic brain injury and brain tumors.Zhang WP, Hu H, Zhang L, Ding W, Yao HT, Chen KD, Sheng WW, Chen Z, Wei EQ. Department of Pharmacology, School of Medicine, Zhejiang University, 353, Yan An Road, Hangzhou 310031, PR China. Cysteinyl leukotrienes (CysLTs) are potent proinflammatory mediators. CysLT receptor 1 (CysLT(1)) is one of the two CysLT receptors that has been cloned. Although the expression of CysLT(1) in the brain has been demonstrated by Northern blot and RT-PCR analyses, the location of CysLT(1) in the brain remains unknown. The objective of this study was to examine the distribution of CysLT(1) by immunohistochemical analysis in human brains with traumatic injury or tumors. CysLT(1) was expressed intensely in the microvascular endothelial cells in both normal and abnormal conditions. At 8 days after traumatic injury, microvascular regeneration was found and all of the endothelial cells highly expressed CysLT(1). In gray and white matters of the normal regions of the brain, CysLT(1) was expressed weekly or not at all. However, the CysLT(1) expression increased in the neuron- and glial-appearing cells in gray and white matters after traumatic brain injury. CysLT(1) was also detected in astrocytoma, ganglioglioma and metastatic adenocarcinoma, and the expression in the neuron- and glial-appearing cells around brain tumors increased robustly.

Here is the relevant part of the study. "Although the expression of CysLT(1) in the brain has been demonstrated by Northern blot and RT-PCR analyses, the location of CysLT(1) in the brain remains unknown." That sentence says that these scientists believe that CysLT1 exists in the brain but they did not know what the location in the brain was. Then they did this study which showed that the receptor existed in the tissues of the brain that are listed above and are too complicated to discuss here.

It is logical to assume that if a receptor exists in any part of the body that it has a function in other words it does something or tells some other part of the body to do something. They have not proved (that takes many studies) what part of the brain or what the receptor does in the brain or what the effect on the body is if the receptor does not do it's job. We do know that Singular (montelukast, Cysteinyl leukotriene receptor 1 antagonist) blocks this particular receptor so if the receptor exists in the brain that it COULD BE POSSIBLE that Singular prevents this receptor in the brain from doing it's job whatever that is. I know that it is difficult to argue with doctors. This drug has been around a long time. It would be difficult to understand why we are just learning about problems after so long a period of time. I can see from all of these responses that these problems are very real. Of course, we have no idea if Singulair is related or not. But if you need something supportive to show that it is not impossible for them to be related even though there is no proof that they are related, you could print this out and discuss it with your doctor.

This isn't proof of anything but at least it might be a clue. It just shows that it is not impossible that Singular affects brain function in some way.

I WAS on Levoxyl for 4 months, I started getting a numb feeling in my feet and legs, pain in my neck and a rapid heart beat. After seeing the doctor about my symptoms he thought I had MS and ordered a brain and spine MRI - the tests were negative for any brain tumors or MS, I decided to take myself off the drug. I've heard of horrible things happening to other people, even death as a result to side effects!!! Do yourself a favor and stop taking the drug if it's causing you serious side effects.
