Tinnitus is a sensation or ringing in the ears. It’s a common problem to all and it affects 1 in every 5 people. Tinnitus is not a disorder itself, but a symptom of a more serious health condition like ear injury, circulatory system disorder or hearing loss.
Symptoms of tinnitus are often associated with ringing, buzzing, roaring, clicking or hissing. For many suffering from this condition, it makes their lives bothersome. Treatment methods for tinnitus often mask the noise or lessen the sensation to make it less noticeable.
TMS as a Possible Way to Cure Tinnitus
Transcranial magnetic stimulation proved as a potential alternative treatment for tinnitus. It induces electrical stimulation of cortical neutrons and it focused magnetic field over the surface of the brain. The magnetic pulses are delivered repeated and a process called repetitive TMS. The low frequency of r TMS shown to alleviate tinnitus perception and it will inhibit the cortical activity in the tinnitus. Its effectiveness of neuro navigated and its effects on the patients with chronic tinnitus using this method of treatment employing an optimization technique in the laboratory.
How TMS Can Help
One particular placebo-controlled study shows how TMS can effectively treat tinnitus. The magnetic field as in microseconds relatively weak and diminishes with distance from the coil. The pulse waves can be delivered at low frequencies that tend to decrease or increase neural activity under the coil. This aim the direct the stimulation of the superficial cortex in a deeper brain structure and its structure in the opposite cerebral hemisphere may be affected by TMS through connecting neural pathways.
Several studies also show how TMS can treat tinnitus patients using low-frequency magnetic pulses applied in the temporal lobe. The session usually lasts for about 30 minutes once a day for 3 to 10 consecutive days.
Some use functional imaging with neuronavigation for choosing the place of treatment based on asymmetrical cortical activation. It targets the left superior temporal lobe in all cases or the other side for the tinnitus. The targeting technique is beneficial for the results that obtained 50% of patients who receive this cure. The effects have been reported to persist 6 months in some other cases and most treatments have demonstrated tinnitus suppression effects last only a few days to a few weeks depending on the response of the patients.
There are several studies showing that tinnitus disorder may have been proposed in a spontaneous otoacoustic emission, thalamocortical dysthymia and maladaptive cortical reorganization due to peripheral injury.
How TMS Works
The repetitive TMS induces electrical stimulation of cortical neurons facing the magnetic pulses in the surface of the brain through a stimulating coil. The usefulness of TMS treatment depends on the materials, physiologic and anatomic variables and stimulating parameters. Health care professionals meticulously calculate the intensity, frequency, duration and time in each session to efficiently directing the excitation of the inhibitory neuron.
Immediate results of TMS treatments depend on the frequency and inhibitory effects on the cortex. The motor cortex shows low-frequency stimulation to gives excitement intermediate effects, and its long duration did monthly. The less duration of the neurobiological mechanisms is involved the low frequency is given in the temporal cortex commonly treat the tinnitus.
This low frequency is applied over the parts to reduce tinnitus by inhibiting activity under the stimulating coil. The imaging techniques will navigate the stimulating coil over the parts within the temporal cortex that will increase metabolic activity. The rational give rise to empirical observations. The treatment of tinnitus used in the combinations of increase and decrease frequency stimulation that goes in the frontal and temporal cortex. The burst frequency will be applied to the cured of tinnitus patients and the burst frequency also applied in the tinnitus patients that may activate brain cell neurons more actively.
A single treatment of this procedure tends to reduce tinnitus disorder for a short period of time. However, treatment efficiency also improves the more a patient undergoes TMS treatment. All the tinnitus patients who undergo TMS treatment show an improved response in the 3 days session of therapy. TMS may provide an effective treatment in normalizing the oscillatory activity or altering the balance activity in brain system that is connected to auditory areas.
