Neurological Disorders Detected by Noninvasive Methods

Research is carried out on Ultrasound and Transcarnial magnetic stimulation as they are believed to have control over neurons.

Neurons are the core components of the nervous system, which includes the brain, spinal cord and the ganglia of the peripheral nervous system.

Inactive or overactive neurons in the brain and other parts of the body are the main reasons for a wide variety of medical conditions. Gaining control over the neurons to fire correctly may help treat many diseases.

Electroencephalogram (EEG): Diagnosis & Testing of Brain Disorders
An electroencephalogram (EEG) detects electrical activity in the brain using electrodes attached to the scalp.

Researchers at Stanford University are hard at work studying how transcranial magnetic stimulation (TMS) and ultrasound can make that happen.

TMS uses strong magnetic fields to stimulate regions of the brain, a technology that can use a good deal of research to narrow and focus the fields and to be able to activate regions deep within the brain.

TMS is used as a diagnostic tool to measure the connection between the brain and a muscle to evaluate damage from stroke, multiple sclerosis, amyotrophic lateral sclerosis, movement disorders, motor neuron disease and injuries and other disorders affecting the facial and other cranial nerves and the spinal cord.

Alzheimer’s disease - Causes, Symptoms, Diagnosis, Stages, Types, Prevention, Prognosis & Treatment
Alzheimer's disease is a progressive neurodegenerative disease affecting memory and thinking and making the person increasingly dependent on others.

During a TMS procedure, a magnetic field generator, or coil is placed near the head of the person receiving the treatment. The coil produces small electrical currents in the region of the brain just under the coil through electromagnetic induction. The coil is connected to a pulse generator, or stimulator, that delivers electrical current to the coil.

Ultrasound has relatively recently been shown to be able to perform similar tricks. The researchers are trying to activate retinal nerve cells in an attempt to help correct vision problems.

Creutzfeldt-Jakob Disease / Transmissible Spongiform Encephalopathy
Creutzfeldt-Jakob disease (CJD) is a rare form of degenerative brain disorder, or brain damage that leads to a rapid decrease of mental function and movement.
