Transcranial magnetic stimulation (TMS)
Transcript of Transcranial magnetic stimulation (TMS)
What is TMS?
Based in the Principle of Electromagnetic Induction;
Activates certain brain parts;
Used by neuroscientists and psychiatrists.
The method had as primary purpose the diagnostic/research.
Prof. Anthony T. Barker
Pioneer in Magnetic Stimulation;
Creates the first TMS machine at 1985, in the University of Sheffield, United Kingdom;
Reginald George Bickford
In 1987, Bickford (USA) realized that his patients started to show significant improvement in their mood (humor).
Neurological and psychiatric illnesses treated by TMS:
• Multiple Sclerosis
• Central Motor Disorders
• Motor Neurone Disease
• Spinal Injury
• OCD Obsessive–compulsive disorder
• Bipolar disorder
• Parkinson's disease

Speech: controlled in the bottom of the left frontal lobe called "Broca's area"
Sing: related with the right temporal lobe
TMS became a technique to treat depression
and other psychiatric diseases.
• Neurological research;
• Cortical mapping and brain research;
• Functional assessment of central motor pathways;
• Early diagnosis, assessment and monitoring of nervous disease.
• Amyotrophic lateral sclerosis
• Chronic Pain
• Post-traumatic Stress Disorder
• Cerebrovascular Accident (CVA)
• Major depressive disorder (MDD)
Mental disorder that affects the self-steem (mood);
Associated with dorsolateral prefrontal cortex(DLPFC) and limbic system;
In the depressed brain: blood flow and neuronal activity on the left DLPFC are decreased.
Also a reverse activity occurs between the two hemispheres.
Curiosities about TMS:
How deep in the brain? 20-30mm
Capacitor voltage: 0-3000 V
Coil current: 0-8000A
Pulse duration: 0.1-0.2 ms
Treatment cost: $2000(BR)~$7000(USA)
TMS Machine price ranges from
US$ 30,000 to US$ 40,000
