description

This presentation gives an over view: of the depression, its symptoms, prevalence, and patho-physiology. It then reviews various treatment options for depression, first starting with medication, and then moving to neuro-modulation. Focus is then on the similarities and differences of ECT and TMS. And finally information is provided about PineWood TMS.

Neural Activity

Page 8: 12-09-13 neuro-modulation power point

When there is an appropriate

amount of monoamine

neurotransmitter activity, neuronal activity

throughout the brain functions

normally.

• Monoamine dysfunction is linked to MDD

• Malfunctioning circuits lead to specific symptoms

Neuron

TMS Directly Depolarizes Cortical Neurons

Pulsed magnetic fields from TMS Coil: • induce a local

electric current in the cortex which depolarizes neurons

• elicit action potentials

• cause the release of chemical neurotransmitters

Depolarization leads to action potentials in local neurons and

thereby releases neurotransmitters

Neurons are “electrochemical

cells” and respond to either electrical

or chemical stimulation

Page 16: 12-09-13 neuro-modulation power point

TMS Releases Neurotransmitters in the Brain

Depolarization of neurons in the DLPFC

causes local neurotransmitter release

Depolarization of pyramidal neurons in the DLPFC causes neurotransmitter release in

deeper brain neurons

Activation of deeper brain neurons then exerts secondary effects on remaining portions of targeted mood circuits

Dorsolateral prefrontal

cortex

Cingulate cortex

These effects are associated with

improvements in depressive symptoms

TMS Mechanism of Action Summary

TMS Therapy:Specifically targets the underlying brain circuits

involved in mood regulationDirectly depolarizes cortical neurons and

modulates neurotransmitter release in the brainEffects involve both the local and deep neural

circuits in the brainAccomplishes these effects without unwanted

systemic adverse effects
