By 25%
What may side effects may the patient report after a ECT procedure
Headache

Nausea
What is transcranial magnetic stimulation
TMS is s noninvasive therapy that uses magnetic pulsations to stimulate specific areas of the brain
What are indications for TMS transcranial magnetic stimulation
MDD
clients who are not responsive to pharmacological tx
What is education about TMS transcranial magnetic stimulation
It is prescribed daily for 4-6 weeks Can be performed on a outpatient basis Procedure lasts 30-40 min A noninvasive electromagnet is placed on the scalp, allowing magnetic pulsations to pass through. Client is alert during the procedure
What are complications of TMS
Common adverse effects are: mild discomfort or tingling sensation at site of electromagnet
Lightheadness
Seizures are rare but possible
Not associated with neurological deficits
What is Vagus nerve stimulation VNS
It provides electrical stimulation through the vagus nerve to the brain through a device that is surgically implanted under the skin on the clients chest.
It is believed to result in an increased level of neurotransmitters
What’re indications of vagus nerve stimulation VNS
Depression that is resistant to pharmacological tx or ECT therapy
What is pt education regarding VNS
It is commonly performed on a outpatient surgical basis
Delivers around the clock programmed pulsations
Client can turn off the VNS device at any time by placing s external magnet over the site of the implant
