30
Electroconvulsive therapy (ECT)
Usually, ECT is done when medications (pharmacologic methods) do not work. It is a procedure done under general anesthesia in which small electric currents are passed though the brain, intentionally triggering a brief seizure. ECT seems to change the brain chemistry that can quickly reverse the symptoms of certain mental illnesses
31

32
Rapid (or Repetitive) Transcranial magnetic stimulation (rTMS)
a noninvasive procedure that uses magnetic fields to stimulate nerve cells in the brain to improve symptoms of depression
33
Deep brain stimulation
electrodes must be surgically implanted into several areas of the brain affected by depression, am insulated wire is connected to an impulse generator that generates stimulations to specific areas of the brain
34
Bright light therapy
particularly helpful for clients experiencing Seasonal Affective Disorder (SAD).

SAD PERSONAS Scale
· S: Sex (1 if male) · A: Age (1 id <19 or >45) · D: Depression or hopelessness (2) · P: Previous attempts or psychiatric care (1) · E: Excessive alcohol or drug use (1) · R: Rational thinking loss (psychotic or organic illness) (1) · S: Separated, widowed, divorced (1) · O: Organized plan or serious attempt (2) · N: No social support (1) · A: Availability of lethal plan · S: Stated future intent (1)
43
SAFE-T: The 5 steps are as follows...
· Identify risk factors · Identify protective factors · Conduct suicide inquiry (note suicidal thoughts, plans, behavior, intent · Determine risk level intervention (determine risk and choose appropriate intervention to address and reduce risk) · Document (assessment of risk, rationale, intervention and follow up)
44
