Brain And Nerve Agent
The brain and spinal cord communicates with what is occurring in the internal organs and limbs by nerve fibers where are like electrical wires with insulation (myelin) and the "copper" (axon). Within brain and spinal cord these nerves connect to other nerves via synapses on both axons and dendrites. A nerve can carry information regarding sensations, and ...Read more
What specific Autoimmune diseases attack brain cells and neurons causing a dramatic effect to neurotransmitters,hormones and the function of the brain
Lupus: Systemic Lupus can attack everywhere and lead to the things u asked about. Other considerations are vasculitis syndromes as there is an autoimmune attack on and in blood vessels which can affect neurons indirectly. Myasthenia Gravis also affect the neuromuscular system and affects one of the main neurotransmitter, AcetylCholine. Rheumotologist is specialist to see for autoimmune disorders ...Read more
What is the difference betweens cranial nerves and neurons in the brain. Is it possible to damage a major cranial nerve?
Cranial nerves: Cranial nerves originate directly from the brain. Spinal nerves emerge from sections of the spinal cord. A nerve is made of a bundle of axons and surrounding myelin from many nerve cells (or neurons). The cranial nerves can certainly become diseased or damaged. For instance, pathology of cranial nerve vii, or the facial nerve, is known as bell's palsy. ...Read more
With peripheral neuropathy, what conditions could cause damage to both axons and myelin as shown in nerve conduction tests? And can it be reversed?
Brief explanation: Most neuropathies affect myelin coverings (Schwann cell), but an advancing axonal neuropathy can secondarily affect the myelin. This is not simple, and you would be far better served by a Concierge consult, and/or find an experienced Medical School neurologist. Reversibility depends on causes and appropriate therapy. ...Read more
Can the immune system attack directly peripheral nervous system go beyond mylein sheath and destroy the whole of the nerve?
Neuropathy: Yes. Immune mediated neuropathies can occur where the primary target is the myelin and the process is so severe that axonal injury (nerve core) can occur. Immune response primarily directed to the axon (nerve core) cam also occur and are typically more severe and less likely to recover from. Secondary myelin injury always occurs in this type of axonal injury. ...Read more
Glutamate receptors: Glutamate is the major excitatory neurotransmitter in the cns, and could be expressed elsewhere in body, but the receptor description used above is designed to study brain pathways pre-dominantly, and has not be studied extensively othewise. Nmda antagonism is mechanism of several drugs, but to date, no successful ampa agonist. ...Read more
Hard to say. : By definition, "alternative" is different than modern western medicine. Generally any drug, herb, treatment, or oil that stands up to rigorous scientific scrutiny is included in modern medicine. Many alternative practices, oils etc do not stand up to scientific scrutiny and cannot be shown to work.nor safe. Some could do serious harm.

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
I have a brain tumor also trigeminal neuralgia . I'm planning on the brain surgrey tumor on the trigeminal neuralgia nerve. Can they remove the tnnerv?
Usually No: It sounds like you have a tumor (usually a meningioma or schwannoma) attached to the trigeminal nerve. This can cause the facial pain that you note. When surgery is done for this, the neurosurgeon can usually peel the tumor away from the nerve. Some fibers of the nerve can be sacrificed hopefully with minimal neurologic sequelae. This is a big nerve and it controls facial sensation and chewing. ...Read moreSee 1 more doctor answer
Brain: Stroke is a condition that primarily affects the brain.There are ischemic strokes where a particular blood vessel is blocked and the part of the brain that is perfused is deprived of blood/oxygen and then dies.There are hemorrhagic strokes where there is the accumulation of blood in the brain (intracerebral hemorrhage)or aneuysmal bleed where the blood spills out into the outer layers of the brain. ...Read moreSee 2 more doctor answers
Can myelin injection treat MS, since the immune system is attacking myelin sheeth adding myelin in blood will keep WBC away from the nerves ,right?
Wrong: This simply doesn't work. It's simplistic and in fact, you're asking for making the body more sensitive. Your body also makes attacking white cells to order when confortonted with something that it's sensitized to. Tolerization procedures exists for some autoimmune diseases and the whole are is fascinating. ...Read moreSee 1 more doctor answer
If the immune system can aggressively attack and kill all peripheral nerves could the human body function with just the central nervous system?
Prion: Prions are proteins that have changed conformation, so that the normal function of the protein inside the cells won't work. The prions' also causes other normal proteins to misfold and make more prions, spreading the process. The prions affect many cells in the body, but they particularly harm nerve cells in the brain, causing progressive rapid degeneration. They are not alive, and have no dna. ...Read more
