Further evaluates prescence and severity of depression from PHQ2
Assist in medication management - take it before and after the medication to gauge if its working
Zung Self Rated Depression Scale
In depth rating of current depressive symptoms
non - pharm treatment for MDD
Psychotherapy, ECT, Vagal nerve, transcranial magnetic stimulation, relaxation techniques, behavioral activation, others - massage therapy, spiruality, yoga, acupuncture
pharm management (3) of MDD
supplements, herbals, antidepressants

ECT - Electroconvulsive Therapy- what is it?
Induce tiny seizure using electric current while under general anesthesia. Delivered in multiple sessions.
Not grand mal. Only way you know its happening is because their foot will do clonus.
ECT
Indications, CI, SE
Indications
- severe referactory depression and can’t tolerate other therapies AND has any of these: severe SI, psychosis, catatonia, malnutrition d/t food refusal
- food refusal can’t be from a medical problem other than depression
- MOST EFFECTIVE for MDD than any other treatment but is LAST LINE
- only used to get someone to respond to meds if they weren’t already
- no CI
- caution in pts with: CVD, neuro path, anticoag therapy
- SE: safe but w/ adverse effects
MC adverse effects of ECT and what patients should caution w/ it
-heart&lungs SE, HA, nausea, transient cog impairement muscle aches
-caution in anyone with CVD, neuro. or anyone on anticoagulent medication
These adverse effects go away!
Vagal nerve stimulation
-connected to LEFT vagal nerve
implanted in the chest wall for refractory EPILEPSY
-questionable efficacy for refractory DEPRESSION
what is Transcranial Magnetic Stimulation
metal coil with magnetic field is placed against scalp to depolarize focal area of neurons
-WITHOUT the use of sedation or anaesthesia
-LESS effective than ECT
Transcranial magnetic stimulation indications
I: refractory depression
CI: seizures, implants that are metal, electric, or cochlear
SE: seizures, HA, scalp pain, transient hearing loss
MDD Supplements
S-Adenosylmethionine (SAMe)
5-Hydroxytryptophan (5-HTP)
Omega-3 Fatty Acids
S-Adenosylmethionine (SAMe)
- Naturally occurs in the body; may raise dopamine levels
- Can be used as an adjunctive for mild to moderate depression in PREGNANT patients
- May trigger manic episodes (dopamine levels going up)
SAM is pregnant and manic
5-Hydroxytryptophan (5-HTP)
Natural precursor to serotonin
Risk of GI upset, serotonin syndrome, eosinophilic myalgia syndrome¹
serotonin makes GI upset
Omega-3 Fatty Acids
May work better if combined with antidepressants (through reducing inflammation. Inflammation is related to the body feeling depression)
May increase risk of bleeding. Problems with it causing bleeding also depending on their medications.
MDD herbals?
St Johns wort, saffron, ginkgo biloba
St. John’s Wort
Increases serotonin, and possibly norepinephrine and dopamine levels
Risk of GI upset, serotonin syndrome, photosensitivity
Numerous drug-drug interactions (DDIs)
St jogns wort = plant = need sunlight so photosensitivity
Saffron
May help with depression; MOA unclear
Risk of GI upset, induce mania, bleeding; can be fatal at high doses
Ginkgo biloba
Improved mood in pts being treated for memory loss; may increase sensitivity to serotonin
May increase risk of bleeding
Guidelines for oral antidepressanat use
start low and slow
Titrate dose over 7 to 10 days
4 to 6 week trial
must have 25% improvement from baseline
- should continue the drug for at least 6 months
- gradual down titration to stop at the end of 6 mo.
Dream team antidepressants?
which ones work best
SSRI - paroxetine, escitalopram
SNRI - venlafaxine
Serotonin Modulators - mirtazapine, vortioxetine
TCAs- amitriptyline
Taz vortex + VAPE
MoA Serotonin
selectively decreases the action of 5-HT reuptake pump
What to do about serotonin syndrome?
Sedation with benzos
Normalize vitals and hydration
D/C serotonergic medications
Clinical diagnosis only. labs don’t correlate
When can I expect serotonin syndrome after prescribing or updating a medication?
within 24 hours.
MC within 1-6 hours
Or if someone tries to overdose
What symptoms does someone have from serotonin syndrome?
important
Diarrhea, incr. bowel sounds, agitation, hyperrflexia, dry mucous membranes, autonomic instability, hyperthermia, HTN, tremor, clonus, seizure, death
