Does resetting the hypothalamus affect pituitary tumor?

Does resetting the hypothalamus affect pituitary tumor?

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 more

Can pituitary tumors cause brain fog and cognitive issues?

Can pituitary tumors cause brain fog and cognitive issues?

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 more

Which body system does brain tumor affect besides nervous system?

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

Can a brain tumor on the pineal gland cause epilepsy?

Can a brain tumor on the pineal gland cause epilepsy?

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 more

Since there's deep brain stimulation that stimulate neurons, is there deep brain "inhibition" that inhibits neurons?

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

What causes brain tumors?

What causes brain tumors?

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 more

How does dopamine and serotonin (chemically) reduce fear/anxiety in de brain? prefrontal cortex or amygdala? Or which parts of brain is involved?

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

Does MS involve the hypothalamus?

Does MS involve the hypothalamus?

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
