Different nerves use different neurotransmitters to convey messages across you would like to see how the whole action of nerve transmission works, please watch this video below. How Neurotransmission Works? (By The ProfessortTed)taken from Facts about our Amazing Nervous System There are 13 500, 000 neurons in the spinal cord, There are more nerve cells in the human brain than there are stars in the Milky Way(I think this is debatable), When we react to touch or danger, the electrical impulses travel along our nerves at a speed of 280kilometres per hour!! Sodium ions and Potassium ions are necessary for the proper functioning of nerves cells Though our nervous system is an extraordinary complex communication system capable of sending out and receiving large amounts of information at the same time, it is still susceptible to diseases and injuries. Conditions such as Alzheimer's and Parkinson's disease can degenerate nerve bacteria and viruses can infect the brain and spinal cord which can cause encephalitis or meningitis.
Drinking alcohol also increases the risk of tinnitus. Certain health problems. Obesity, cardiovascular problems, high blood pressure, and a history of arthritis or head injury all increase your risk of tinnitus. Complications Tinnitus affects people differently. For some people, tinnitus can significantly affect quality of life. If you have tinnitus, you may also experience: Fatigue Stress Sleep problems Trouble concentrating Memory problems Depression Anxiety and irritability Headaches Problems with work and family life Treating these linked conditions may not affect tinnitus directly, but it can help you feel better. Prevention In many cases, tinnitus is the result of something that can't be prevented. However, some precautions can help prevent certain kinds of tinnitus. Use hearing protection. Over time, exposure to loud sounds can damage the nerves in the ears, causing hearing loss and tinnitus. Try to limit your exposure to loud sounds. And if you cannot avoid loud sounds, use ear protection to help protect your hearing.
Hello Everyone Today we will discuss a new drug treatment for tinnitus. These drugs have the potential of helping tinnitus sufferers by working on a pathway that is said to be "malfunctioning" with the brain. What is of further interest is that this drug is said to be effective in people suffering from epilepsy as well. Tinnitus and the Brain In one of my earlier posts, I have covered the relationship between tinnitus and the brain and touched upon how injury to the brain can bring upon ringing in the ears, which is a characteristic symptom of tinnitus. Just to briefly recap, after exposure to any injury(e. g loud noise), the brain loses control of pathways, which, if properly regulated, will NOT bring about tinnitus. So, therefore, it makes sense if we are to find a way to control or regulate these pathways, then we will be able to 'control' tinnitus. The drug that I am going to talk about works on these pathways, more specifically the Potassium Channels. It is still in its infancy stages, but if the FDA(Food and Drug Administration) trials are successful, then it could show promise for tinnitus sufferers around the world.
Tinnitus drug treatment is advised by a doctor to help reduce severe symptoms or complications of tinnitus. A word of warning, though- there are still NO drugs that can COMPLETELY cure tinnitus.

A word of warning, though- there are still NO drugs that can COMPLETELY cure tinnitus. Medications for severe tinnitus Some medications that are prescribed for severe tinnitus are tricyclic anti-depressants such as nortriptyline and amitriptyline. However, these drugs are restricted only to severe tinnitus since they can cause irritating side effects such as heart problems, blurred vision, dry mouth and constipation. Alprazolam such as Niravam and Xanax which are anti-anxiety drugs are also reliable in reducing tinnitus symptoms but can also cause side effects such as nausea and drowsiness.
The Facts Tinnitus (or "ringing in the ears") is sound or noise that no one but the person with the condition can hear. The noise can be constant or come in short bursts; it can last for long periods of time or go away fairly soon. The sound can be loud or soft, can change in pitch, and can be heard in one or both ears. Each person who has tinnitus can probably describe it in a different way. It is estimated that about 10% to 15% of the population experience tinnitus. Some studies have shown that the prevalence of troublesome tinnitus increases with age, and it impacts both men and women equally. Causes The causes of tinnitus aren't completely known or understood and reasons can't always be found. In many cases, though, the sounds can be caused by illnesses or injuries such as: heart disease or high blood pressure infections in the ear or sinuses drug side effects blows to the head hearing trauma such as exposure to loud explosions or to extremely loud music hearing loss objects lodged in the ear canal or a buildup of ear wax dental problems certain types of tumours Symptoms and Complications Tinnitus, by definition, is a subjective ringing or tingling in the ear that can only be heard by the person experiencing it.
Sometimes, tinnitus goes away spontaneously, without any intervention at all. It should be understood, however, that not all tinnitus can be eliminated or reduced, no matter the cause. Continued If you are having difficulty coping with your tinnitus, you may find counseling and support groups helpful. Ask your doctor for a referral. If the cause of your tinnitus is excessive earwax, your doctor will clean out your ears by suction with a small curved instrument called a curette, or gently flush it out with warm water. If you have an ear infection, you may be given prescription ear drops containing hydrocortisone to help relieve the itching and an antibiotic to fight the infection. Surgery may be necessary in rare cases of a tumor, cyst, or otosclerosis (a calcium deposit on the ear bone). If your tinnitus is the result of temporomandibular joint syndrome -- sometimes called TMJ -- your doctor will probably refer you to an orthodontist or other dental specialist for appropriate treatment.
For this reason it is reserved only for people who did not show any results with other anti-epileptic drugs. SF0034 Another new drug treatment for tinnitus was called SFOO34 which was developed by a company called SciFlour. A neurobiologist by the name of Dr Thanos Tzounopoulos, at the University of Pittsburgh who specializes in tinnitus contacted Tzingounis, in 2013 and asked if he would like to do a trial on this new drug. Chemically, this drug was similar in structure to Retigabine, except that the molecule was modified with an extra Fluorine atom. This modification changed certain characteristics of the drug, but the fundamental purpose of blocking the potassium channels were still evident. So, does SF0034 show promise or is it worse than its parent drug? What was great about this drug is that it only acted upon the KCNQ2 and KCNQ3 potassium channels. Because it does not act on the KCNQ4 and KCNQ5 channels, it is more selective over Retigabine. Animal studies showed a decrease in seizures as well.
There may well be a suitable alternative medication or a different dosage regime that may help. Recreational drugs Although the BTA cannot condone the use of such substances, there is no evidence that marijuana, cocaine or heroin usage increases the risk of developing tinnitus. Indeed there has been discussion among some patient groups as to whether marijuana could help tinnitus. Although there is not much research on this topic, the evidence that is available suggests that it is not helpful. The use of hallucinogenic drugs and inhalants (solvents) does seem to be associated with increased risk of developing tinnitus.
