Generalized Anxiety Disorder (GAD):
Know core symptoms
Usually characterized by an incessant feeling of anxiety that impedes your day-to-day functioning––-GAD is different from agoraphobia because this anxiety expands to everything and is not specific to a situation
Restlessness, fatigue, insomnia, irritability, concentration difficulties, muscle tension
Uncertainty intolerance
Core DSM Diagnostic Criteria
High anxiety & excessive worry for over 6 months
90% meet DSM criteria for another disorder (co-morbidity), major overlap with depression
People with depression will usually have GAD, people with GAD are basically guaranteed a clinical diagnosis depression diagnosis at some point in their lives
Uncertainty intolerance
Not being able to accept that you don’t know the outcome (being anxious about the lack of predictability)
This uncertainty intolerance will lead to people with GAD to try and control the situation or leave it entirely
Error detection (anterior cingulate cortex)
I need to double check my notes but people with GAD have super twitch ACCs because anything that their brain deems “wrong” or “out of place” sets off the error detection circuits in their brain (like a Christmas tree) and tells them that they need to fix it (it’s highly related to control)
Explains why some people with GAD can be control freaks or really particular or bossy––they like the predictability of things and if they’re the ones controlling it, there’s no way that things can go wrong (in their mind)
The brain notices when they’re having trouble walking itself through a situation, this creates a prediction error that then sets it off (so I was basically right above :P)
Sex ratio = 2:1, female:male (similar for other anxiety disorders)
I’ll have to check my notes for this one but I think he was saying something about how men and women are socialized…
This also goes to the amount of testosterone and estrogen in our systems (he talked more about this with panic disorder so see below ig)
Basic facts about use of SSRIs/SNRIs & benzos in GAD (no need to know specific numbers or %)
––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––
Benzodiazepines:
Short-term (versus long-term) efficacy in treatment of panic, GAD
Benzos work super quickly (which is why they’re party drugs)
Work via GABA (brain’s major inhibitory neurotransmitter) receptors
I don’t have any other notes about this so I guess just remember this part? (remember GABA = inhibitory transmitter receptors)
Know Xanax, Ativan, Klonopin, Valium
Major their major side effects (covered in class)
Xanax
Acts super quick, can take effect anywhere between 15/20 minutes to an hour
Ativan
Standard benzo––highly addictive, quick to act, high relapse, commonly prescribed
Klonopin
Will stay in the body for the longest because the half-life is so high
Valium
Standard benzo––highly addictive, quick to act, high relapse, commonly prescribed
Potential to suppress slow-wave sleep, trigger depression
These are iatrogenic effects
Slow-wave sleep is the most restorative, so without it your brain isn’t able to repair brain cells and stuff
Addiction potential (and withdrawal syndrome)
Their half-life is horrible though so your body will build a tolerance effect to it pretty quickly
Because of this, it’s vital that you never go cold turkey because even if you don’t feel the effects, it’s still coursing in your bloodstream so you will go through withdrawal
This will cause addiction because without it running in your system (or, without weaning off of it), you’re gonna crave that “normal” feeling
Evidence of possible permanent alteration of GABA receptors
When did he ever talk about this…
Increased dementia risk
This is an iatrogenic effect
Recent studies show a more than 50 percent increase in risk
Estimated 85% of prescriptions written by non-psychiatrists
This is the same premise as the other exam I think
More relevant with benzos because it allows non-psychiatrists to “solve” their patient’s problem and get on with their day
Antidepressants: SSRIs & SNRIs
Major SSRIs: Prozac, Paxil, Zoloft, Celexa, Lexapro (be able to list/recognize them)
Major SNRIs: Effexor, Pristiq, Cymbalta (be able to list them)
These drugs do not increase “serotonin levels”
They inhibit synaptic re-uptake of serotonin, with downstream effects that take 2-6 weeks
Emotional numbing
It’s their job to make people feel the effect of things less
Because our bodies don’t have the capacity to determine exactly what emotions should and should not be repressed, it just blunts everything
You don’t want to feel depressed anymore so that’s why the meds work, but that also means you won’t be able to feel anger or excitement or whatever because it’s an all or nothing deal
Anorgasmia (sexual side effects)
… He never specified this term but basically because antidepressants suppress everything, the already low sex drive that people have when depressed basically disappears
I think this is when someone asked about someone’s human desire to vent sexual frustration but not actually having sex drive, which literally makes no sense so do not pay attention to this part yet
Activation syndrome (2-5%)
2-5% of people taking SSRIs/SNRIs experience such negative emotions as a side effect that it becomes ridiculously severe and makes

Basics of CBT for GAD
Focus here is on imaginary simulation and uncertainty tolerance
Imaginary simulation: imagining what will happen so that your brain has an idea of what’s going to happen next
Uncertainty tolerance: goes with imaginary simulation––it’s basically training the brain to be able to tolerate not knowing
Imaginary simulation helps here because there’s not uncertainty if you have an idea of what’s going to happen
