Magnetoencephalographic (MEG) recordings of Parkinson's diseased (PD) patients were obtained using a whole-head 122-channel magnetometer and analyzed with Fourier statistical analysis. External transcranial magnetic stimulation (TMS) in the order of pico Tesla was applied on the above patients with proper field characteristics (magnetic amplitude : 1-7.5 pT, frequency : the alpha-rhythm of the patient: 8-13 Hz) which were obtained prior to TMS. The MEG recordings after the application of TMS…

Pico Tesla TMS in Parkinson’s Disease

The pT-TMS has some possible effects to be considered as a non-invasive secure and efficient modality in managing the Parkinson’s disease patients, but further investigation is needed before firm conclusions can be drawn.

MEG Evaluation of the Effects of Pico-Tesla External TMS on Migraine Patients

The pT-TMS has the potential to be an important non invasive safe and efficacious modality in the management of idiopathic migraine patients and an increase in the 2 7Hz frequencies range toward the patients’ alpha rhythm followed by an improvement of their MEG.

Pico-Tesla TMS Therapy on Multiple Sclerosis

The pT-TMS has the prospective to be a significant noninvasive secure and effective means in managing MS symptoms and was observed with an increase of frequencies among the participants.

MEG recordings of patients with cerebral palsy before and after the application of pico-Tesla weak magnetic fields.

The appliance of pico-Tesla weak magnetic fields showed the brains of the cerebral palsy patients had an enhance of the frequencies of (2-7 Hz) for each patient, and suggested the stimulation provided a positive contribution to the management of the symptoms of cerebral palsY patients.

Pico-Tesla External TMS on Dystonia Patients with a Double Blind Experimental Design. A MEG Study

The pT-TMS seems to be an important non-invasive safe and efficacious modality in the management of idiopathic migraine patients, although more studies and additional investigations using controlled and larger samples should be performed before firm conclusions can be drawn.

It is found that 7 out of 10 patients (70%) had increased their 2-7Hz frequencies after the application of pT-TMS, and frequency analysis is a promising means for the assessment of epilepsy disorders.

Combined MEG and pT-TMS study in Parkinson's disease.

There is a significant effect of an increase of frequencies in the range of 2-7 Hz across subjects in pico-Tesla transcranial magnetic stimulation of Parkinson's disease.

MEG Study with Pico-Tesla External TMS on Children with Dystonia

A significant effect of an increase in the 2-7Hz frequencies range toward the patients’ alpha-rhythm which is ranged from 8-13Hz and were above the baseline frequencies is found.

Pico-Tesla Transcranial Magnetic Stimulation on Depression Patients with Double Blind Experimental Design

This method of the pT-TMS has the potential to be a significant non invasive, secure and valuable means in the managing of patients with depression.

MEG and Pico-Tesla-TMS in Patients with Atrophy with a Double Blind Experimental Design

The pT-TMS was applied to 5 male patients with cerebral atrophy with age ranging from 19-25 years with magnetic field amplitude and frequency and 4 out of 5 patients were statistically significant.

Nonlinear Analysis of Brain Activity in Magnetic Influenced Parkinson Patients

The increased values of D of the MEG after the application of EMS, when compared with the corresponding ones obtained from the M EGs prior to the EMS, suggest that the neural dynamics are strongly influenced by theApplication of EMS.

Transcranial magnetic stimulation and Parkinson’s disease

The cerebral oscillatory network of parkinsonian resting tremor.

Tremor-related oscillatory activity within a cerebral network, with abnormal coupling in a cerebello-diencephalic-cortical loop and cortical motor (M1, SMA/CMA, PM) and sensory (SII, PPC) areas contralateral to the tremor hand is demonstrated.

Magnetic Stimulation Can Modulate Seizures in Epileptic Patients

The increased values of the dimensional complexity and the lower activity of the MEG after the application of EMS strongly supports the beneficial effects of EMS in epileptic patients.

Changes in excitability of motor cortical circuitry in patients with parkinson's disease

There may be abnormalities of motor cortical inhibitory mechanisms in patients with Parkinson's disease that are not readily detected using threshold or silent period measurements alone, and it is suggested that the silent period was significantly prolonged when ON compared with OFF.

The biological effects of magnetic stimulation in epileptic patients.

The findings indicate that the use of low external magnetic fields produce substantial attenuation in seizure activity in epileptic patients and therefore it may open new ways in the future for management of epileptic activity.

Dependence of subthalamic nucleus oscillations on movement and dopamine in Parkinson's disease.

It is suggested that the firing of STN neurones can be synchronized by 15-30 Hz cortical beta oscillatory activity, particularly when dopamine deficiency results in a higher background firing rate of STn neurones, and that this synchronization contributes to parkinsonian pathophysiology.

Attenuation of epilepsy with application of external magnetic fields: a case report.

This case demonstrates that artificial magnetic treatment may be a valuable adjunctive procedure in the management of epilepsy and presents a patient with severe epilepsy and behavioral disturbances in whom application of an external artificial magnetic field of low intensity produced a substantial attenuation of seizure frequency which coincided with an improvement in the patient's behavior.
