110
Placement of high vs low frequency

112
Types of Theta Burst Stimulation
--> Intermittent TBS (iTBS) --> INCREASES cortical excitability -2s train of TBS q10s for 190s --> Continuous TBS (cTBS) --> DECREASES cortical excitability -continuous 40s train
113
What is transcranial direct current stimulation?
Modulates cortical excitability through the delivery of a constant, weak electrical current via surface scalp electrodes -can be delivered at home Current evidence DOES NOT SUPPORT use of tDCS for those w/ severe depression or DTD Considered third-line adjunctive for mild-mod MDE
114
What is magnetic seizure therapy?
MST was developed to mitigate cognitive SEs of ECT. Instead of placing electrodes directly on the scalp as with ECT, MST uses vertex of frontal placement of single or paired circular coils to deliver transcranial magnetic stimulation -the high intensity and frequency of TSM induces an electrical field and elicits a generalized seizure MST is considered INVESTIGATIONAL as per CANMAT due to limited evidence
115
Recommendations for rTMS from CANMAT
First-line: -iTBS to LEFT DLPFC -High-frequency rTMS to LEFT DLPFC -Low-frequency rTMS to RIGHT DLPFC Second-line: -Sequential bilateral rTMS to DLPFC (right low frequency then left high frequency) -Accelerated iTBS to LEFT DLPFC -Sequential bilateral TBS to DLPFC (right continuous then left intermittent TBS)
