Depends on case: If you mean suppressing the gland, such as using bromocryptine for a pituitary adenoma, it can help control the symtpoms and prolactinomas can shrink. For other tumors, this may not be the case art all - for metastases to the pituitary or for craniopharyngioma, addressing hormone function generally does not affect the tumor's growth, although hormone symptoms can be relieved quite a bit. ...Read moreSee 1 more doctor answer
Do you have one?: Have you been diagnosed with a pituitary tumor? I suppose it's possible for a pituitary tumor to cause those symptoms, e.g. secondary hypothyroidism; but usually there are also physical symptoms. If you mean a BIG GROWING tumor, you shouldn't have that without also developing a bitemporal hemianopsia and walking into doorposts and walls. Why does this in particular worry you? ...Read moreSee 1 more doctor answer
Depends on type: The type and location of the brain tumor may affect other body systems. For example, a pituitary tumor is a classic tumor that arises in the pituitary fossa. It can have profound effects on the endocrine system as it diplaces normal pituitary function. If the tumors are endocrine active-it can afffect growth or blood pressure. Tumors near motor areas can affect the musculoskeletal system. ...Read more
Not typically: The pineal gland is located in the center of the brain near eye nerve pathways and the cerebrospinal fluid (CSF) system. Symptoms include double vision, headache, nausea, & vomiting. I suspect seizures could happen but are not common. Pineal tumors are also rare .. only 1% of all primary brain tumors. Other causes of seizures should be investigated. ...Read moreSee 1 more doctor answer
Since there's deep brain stimulation that stimulate neurons, is there deep brain "inhibition" that inhibits neurons?
Yes: It is interesting that it is called " stimulation", in fact it inhibits the neuron depending upon the degree of stimulation applied. For example the involuntary movement of Parkinson's disease are controlled by "inhibition". Similarly " interstim" is the technique to stimulate to cause inhibition of bladder contractions to cure loss of urinaty control. The entire process is well understood. ...Read more
Neurosurgeon: Most neurosurgeons can do this surgery. Depending on the size of the pineal tumor, you may want to call around to different universities or large medical centers and ask if there is a neurosurgeon who does endoscopic surgery and may do your tumor. But any neurosurgeon can give you the proper consultation. ...Read more
Multi-factorial: There are 4 things that contribute to all tumors: 1. Genetics 2. Mutation inducing factors (examples: smoking, drinking, etc). 3. Aging 3. Unknown causes (there are definitely people without family history or obvious "bad habits" that develop brain tumors). ...Read moreSee 1 more doctor answer
Pathology type: Brain tumor is a generic term that includes benign, low grade and malignant brain tumors. Brain cancer refers to the malignant category. When one speaks of a brain cancer, this may be a primary (originating from the brain tissue) or metastatic (originating from cancer outside of the brain). Treatment depends on the type of cancer. ...Read more
How does dopamine and serotonin (chemically) reduce fear/anxiety in de brain? prefrontal cortex or amygdala? Or which parts of brain is involved?
Neurotransmitters: Medicines like Zoloft/Lexapro are serotonin reuptake inhibitors. Wellbutrin (bupropion) inhibits the uptake of norepinephrine and dopamine. Whether it is anxiety, irritability, anger, short fuse, or depression; these medicines regulate neurotransmitters in the brain to improve symptoms of insomnia, guilty feelings, poor concentration, fatigue, appetite disturbance, and lack of drive/interests. ...Read more
Yes, it surely can: There is considerable evidence that involvement of the hypothalamic-pituitary-adrenal axis can play a role in fatigue. Many ms patients do develop a variety of sleep disorders and a loss of hypocretin-i-secreting cells may be due to autoimmune mechanisms, perhaps enhancing daytime sleepiness. (seems some overlap with hla-dr-2 typing, as related to both ms and narcolepsy). ...Read more
It depends: This is a difficult question to answer because it really depends on where the cancer is in the brain and how extensive it is. Different parts of the brain are responsible for different things. So for example it is possible that a brain cancer could impact someone's speech for one person but not another. ...Read moreSee 1 more doctor answer
Some do, some don't: A lot depends on the location of the tumor, it's size, the swelling around it, which fiber tracks are blocked and chemicals emitted from the tumor, as well as the person's psychological reaction to having a brain tumor, family support, accurate and timely treatment, etc. ...Read more
