Depression
Mood Disorder
6.6% of Americans
25-30% suicide rate (untreated)
50% treated, 42% adequately
Medication and Psychotherapy useful
Co-morbid w/ANXIETY, substance abuse
general info
Symptoms of Depression
socially withdrawn
hyper/insomnia (sleep probs)
Anhedonia (loss of pleasure)
Suicidal Ideation
appetite disturbances
Lethargy
negative/restrictive affect
concentration/attention--> impaired memory (encoding)
feelings of worthlessness/helplessness/hopelessness
9 of them
Diagnosing Depression
* Anyone w/majority of these symptoms for 2 weeks = major depressive episode (which can last up to several months)
*recurrent depressive episodes = major depressive disorder
History of Antidepressants
Medical treatments for approx. 60 yrs
1st drug = Imipramine & tricyclics
MAOIs = monoamine oxidase inhibitors
2nd Generation/Atypical Antidepressants (welbutrin)
SSRIs
yrs and 4 classes of antidepressants
Depression + Anxiety
Agitated, anxious depression
usually don't sleep
weight loss
Dysthymia
chronic, low grade depression
fairly fxl (hold job, family)
can fx but they are not happy
**major depressive episodes are much easier to treat than dysthymics! dysthymics don't respond to txs!!!**
symptoms
who is easier to treat?
*Neurotransmitters affected by depression?
** NE
** DA
** SE
Pathophysiology of Depression
Reversible disease in brain
now seen as a disorder of neuronal plasticity (neurons that aren't fxing as good as they can) ~ meds jumpstart this
Stress-induced vulnerability leads to:
* genetic-environment interaction (family risk)
* the more dep. episodes one has the greater the risk for more
MAOIs
Mono Amine Oxidase Inhibitors
Used since 1950s
Nardil, Parnate, Marplan
INactive for about 20 yrs - not used much anymore - used mostly as an absolute last resort
...Logical Effects of MAOIs
*MAO is an enzyme that breaks down NE, SE, DA
*SO, MAOIs stop the breakdown of these neurotrans. to keep up higher levels in brain/body!!
Types of MAOIs
MAO-A: breakdown of NE & SE
MAO-B: breakdown of DA
MAOIs inhibit BOTH MAO-A & B but it is most important to break down the As
*It is thought that it is the breakdown of B that causes the nasty side fx.
A & B
What do they do?
Side Effects of MAOIs
Drug Interactions with: cold meds, antihystamines, nesal sprays - if you take them there is a HIGH risk of cardiac arrest
(**old ppl - they take a lotta meds!)
FOOD INTERACTIONS: TYRAMINE (protein found in MANY foods - any foods that are fermented!)
*Must follow very strict diet to be on these meds but that is hard to do due to increased risk of suicide and concentration is hard to follow!
First Generation Antidepressants: Tricyclic Antidep.s
Antidepressant, anxiolytic, analgesic effects
Set standard for antidep. meds!
Much less side fx than MAOIs
Mechanism of Action for Trycyclics
*BLOCK NE reuptake
*BLOCK SE reuptake

Side fx come from:
Blocks histamine receptors
Blocks ACh receptors (causes blurred vision, urinary probs, dry mouth, speech fx, prolonged periods may cause tooth decay)
...Kinetics of Tricyclics
...Logical fx of " "
KINETICS
*orally
*relatively long 1/2 life
*usually take b4 bed (1x/day)
LOGICAL
elevate mood
improve sleep & appetite patterns
reduce morbid preoccupation
analgesia
anxiolytic (commonly used to treat many anxiety disorders)
Side Effects of Tricyclics
Long onset (can take 4-8 wks to feel fx of meds)
must be taking them for an adequate time (1-2 mos) at an adequate dose
------------------------------
*Anticholinergic fx: headaches, dry mouth, urinary retention, blurred vision
*impaired: attn, motor speed fx, memory probs
*cardiac depression/arrhythmias, cardiotoxicity
*LETHAL in overdose!

good for anxiolytic depressants
safe in overdose
can cause increase in cardiac arrhythmia
POSSIBLE priapism (prolonged erection) but rare
Atypicals -
Buproprin
BUPROPRIN (wellbutrin):
*DA & NE reuptake inhibitor
anti-craving & anti-depressant
not sedating or toxic
can cause low blood pressure
can cause weight loss
**can be overstimulating (not good w/anxiety)
lowers seizure threshold
Atypical -
Clomipramine
(Anafranil)
structured like a tricyclic
used mostly for OCD
toxic in overdose
can inc. seizure risk
can cause psychosis
can dec. sex drive
can cause weight gain
can activate mania in those who may be bipolar/manic depressive
Atypical -
Vanlafaxine
(Effexor)
BLOCKS NE & SE
Lack the Ach side fx!
As effective as SSRIs
Good for pain! (analgesia)
Useful for fibromyalgia & chronic fatigue
SSRIs
History
Drugs (names)
Selective Serotonin Reuptake Inhibitors
--------------------------------
15-20 yr history
1st was Prozac
Revolutionized tx of depression due to drastic reduction in side fx
**ALL BLOCK ONLY SE!!**
More easily available via PCP
All equally effective w/minimal diff's, but are NOT interchangeable
Probably won't overdose!

*Prozac, Paxil, Zoloft, Luvox, Celexa, Lexapro*
Clinical Uses for SSRIs
Major Depression
Dysthymia
Anxiety Disorders (Panic, OCD, Generalized Anxiety)
*Main form of tx for depressants & anxieties*
Serotonin Syndrome
*high dose of 1 drug, more than 1 of them*
---------------------------------
Disorientation, confusion, hypomanic behavior (low mania), fevers, chills, sweats, diarrhea, inc. BP, attacacardia, ataxia (stumbling), hyperflexivity (jittery), visual hallucinations
*Most risky for this = Paxil
*Side fx will go away when the drug is stopped and can get worse if drug still taken
*Don't take other drugs!
Serotonin Withdrawal Syndrome
happens if you abruptly stop taking the meds - happens in 60% those who stop cold turkey!
---------------------------------
onset in a few days, can last 3-4 weeks
disequilibria, bad GI probs, fatigue, chills, sweats, sensory disturbances, electric shock feelings, insomnia, vivid dreams, anxious, irritability, easily agitated, prone to crying spells
*will stop if you start taking meds again
*likelihood of not happening if taken off meds properly
*LEAST likely to happen w/Prozac!
2 MAJOR SIDE FX OF SSRIs
1) GI Probs: upset stomach, bloating, gas
- tends to disappate after a week or so.
2) Sexual dysfunctions: male and female
-makes ppl stop taking meds
-dec. libido, ED, vaginal dryness, inability to achieve orgasm --> relationship difficulties
*reduce dose; try another med! (but will probably still get this with other SSRIs)
Prozac
(Fluoxetine)
-1st SSRI
-Long 1/2 life

*5X more potent than prozac!
---------------------------------
-OCD!!!
Celexa & Lexapro
(Citalopram) (Escitalopram)
-GOOD as anti-dep. and anti-anxiety (comorbidity!)
-Celexapro = 2x stronger than Celexa
-Potentially cause worst probs w/overdose --> in EXTREMELY high doses, can cause cardiac probs.
MOOD STABILIZERS
BIPOLAR DISORDER
Bipolar I
Bipolar II
Cyclothymia
Substance Abuse
Bipolar Disorder
Manic-Depressive Disorder
Recurrent episodes of mania and depression
5% of population
Bipolar I: manic episode was severe enough it needed hospitalization
Bipolar II: less severe manic episode
Cyclothymia: recurrent mood swings between depression and elation but less than BPII
"Rapid Cyclers": 4 illness episodes in a 12-mo period
------------------------------
1 in 4 or 5 bipolar people commits suicide
1/3 of BP patients are in active tx

-55% have history of substance abuse
Mood Stabilizers
What do they do??
-Stabilize acute mania, mixed, and depressive symptoms
-does not induce the alternate mood symptom
-prevents relapses into mania, mixed or depressive symptoms or episodes
Goals in Tx
Types of Drugs used in tx of BP
-Treat acute episodes of mania
-reduce recurrence of manic episodes
-maintain compliance w/therapy
-treat accompanying depression, psychosis, substance abuse
-establish/maintain therapeutic alliances
-promote regular patterns of activity and sleep
-anticipate stressors
-minimize fx'l impairment

--------------------------------
-Lithium
-Anticonvulsant neuromodulators
-Atypical antipsychotics
-Omega-3 Fatty Acids
Mood Stabilizer -
Lithium
(brief info - card 1)
Classic mood stablizer
effectively controls manic symptoms
reduces rate of recurrence
MANY serious and bothersome side fx and toxicity
BP - Neuronal Injury
BP is classified as a neurochemical disorder
differences in neuron densities (like depression)
BP is a deteriorating disorder if left untreated
*lithium & valproic acid inc. levels of cellular-protective protein --> reduction of brain damage and facilitation of neuronal recovery after brain injury!!*
Mood Stabilizer -
Lithium
*history/use
-was used in '20s as sedative-hypnotic for anticonvulsants
-'40s: used as salt substitute for heart disease patients
-use soared in '70s when it was found to be really good for mania ~ use declining now
Lithium
...Kinetics
...Kinetics
-orally (absorbed fast and completely) - peak in 3 hrs
-crosses BBB slowly and incompletely
-Long 1/2 life - takes about 1-2 weeks to reach steady state = 1x/day usage

-memory probs, weight gain --> therapy compliance issues
-enlarged thyroid, rashes and skin eruptions, frequent urges to pee, inc. in thirst and water intake
-cognitive deficits
Lithium -
Pregnancy
Noncompliance
Combo Therapy
Preggy: not recommended - can cause increase in teratogenic fx, esp in heart of fetus.
- use other mood stabilizers if they're needed during preggy.
Noncompliance: 50% of patients stop taking lithium against medical advice
-result of intolerance of side fx to drugs
-result of missing the "high" feeling of mania
Combos: lithium + antiepileptic drugs
MOOD STABILIZER -
Neuromodulator Anticonvulsants

Txs:
-SSRIs -Psychotherapy -used to use benzos, not anymore
-hardest to treat of all anxiety disorders (besides PTSD)!!!!
TREATING ANXIETY DISORDERS
Panic Disorder
-frequent panic attacks:
heart beats fast, sweaty, sympathetic nervous system kicks in - thinks ur having a heart attack; intense crippling feeling
-ppl who are very sensitive to what is going on in their body; abnormal breathing

Panic Disorder W/ and W/OUT agoraphobia (restriction of behavior based on fear of having a panic attack)
-develops through classical conditioning
*if u have an attack at a mall you fear public places;
then another happens in ur car so u don't drive;
then happens while walking so u end up staying inside!
-----------------------------
Txs:
-SSRIs (to decrease anxiety)
-Benzos (before CNS response kicks in)
-Psychotherapy (hugely effective WITH and WITHOUT meds!)
TREATING ANXIETY DISORDERS
Phobias
-Irrational fear and/or avoidance of a specific object or situation that interferes with normal fx-ing
-Social Phobias:
*fear of embarrassment/evaluation by others
*don't initiate conversations
-Very treatable with psychotherapy
-Tx = systematic desensitization - exposure to the fear!!!
TREATING ANXIETY DISORDERS
OCD
Obsessions: unwanted, intrusive disturbing thoughts that cause ppl to become very anxious
*germs, imminent danger, orderliness

Compulsions: designed to reduce anxiety
*washing, checking, repeated rituals

Reinforcement Paradigm: negative reinforcement
*have obsession, get anxiety, do compulsive act to ease anxiety temporarily then it starts all over again.
*negative reinforcement occurs b/c you take away the anxiety w/the compulsion

-interferes w/normal, everyday fx-ing
-Tx:
*SSRIs
*Exposure & Response prevention
TREATING ANXIETY DISORDERS
PTSD
-Perceived life threatening trauma
-flashbacks, Flashbacks, sleep disturbance (don’t sleep well and when they do they tend to have nightmares), heightened startle reflex, hyper-vigilant (avoid any triggers or stimuli that reminds them of their trauma), intense anxiety and depression, severe emotional disregulation, high incidence of substance abuse
-Tx:
*Anxiolytics (to relieve anxiety and depression)
*Psychotherapy
*cognitive reprocessing therapy
ANXIOLYTICS -

BENZOs
-used for 50-60+ years for use in anxiety, seizures, sleep probs
**TOTAL GABA AGONISTS!!!!**

Facilitate binding of gaba to post-synaptic neuron – hyperpolarizes that neuron = less likely to fire = less cns activity = cns depressant effect

VERY good at treating anxiety disorders!
Benzos -
...kinetics
-taken orally, processed by GI tract
-sometimes injectable; sometimes under tongue
-Short, Intermediate and Long-Acting benzos
*long acting stay in system for many, many hours!!!
*elderly don't tolerate well - stay in system too long and they can't tolerate it. ~ but, elderly are always anxious and they can't do much else!
Benzos -
Long-Acting
Intermediate-Acting
Short-Acting

*1/2 life; Specific Drugs
-1/2 life = 20-100 hrs!

------------------------------
-1/2 life = 10-50 hrs
-Lorazepam (Ativan) {fast-acting, sedating effects – used for psychotics}, Clonazepam (Klonopin) {very commonly used to treat anxiety – least addicting – panic disorder, gen. anxiety, ptsd}
------------------------------
1/2 life = 1.5-3.5 hrs
-Temazepam (restoril) {wipes out STM in medical procedures}, Oxazepam (Serax) {old anti-anxiety med},Temazepam (Restoril), Triazolam (Halcion){sleep med}, Alprazolam (Xanax) {most dangerous in addiction potential, very short ½ life – most commonly used for panic disorder (prescribed as needed) – rebound anxiety caused by the short ½ life, prescribed to help people fall asleep – very small doses}
BENZOs -
Clinical Uses & Limitations
Side Fx
-Sleep, alcohol detox, sedatives during surgeries, anti-seizures (not 1st line, though)
-not safe for elderly, adolescents or kids
-high risk of conjuction w/alcohol

**VERY SIMILAR TO ALCOHOL**

-Hard to overdose but probably wouldn't die from overdosing-
Benzos -
Tolerance and Dependence
Preggy
-DO develop tolerance AND dependence!!
-can't be used at high doses for a long time!
-if you do need to take it long time, use klonapin!
------------------------------
-freely passes BBB and placental barrier
-"floppy baby syndrome"
SECOND GENERATION ANXIOLYTICS
-similar to benzos but NOT benzos!-
-Used for sleep! very sedating!
-Ambien, Sonata, Imovane
**Partial agonists at GABA-A receptors!!!**
--------------------------------
Serotonergic anxiolytics: SSRIs - inhibit serotonin reuptake helps w/anxiety
*they work and they work well but they take a long time to work!
-------------------------------
Anticonvulsants as anxiolytics: not used much anymore
-------------------------------
*Anti-depressants as anxiolytics: front line of treatment!!*
SCHIZOPHRENIA

(antipsychotics)
-"split mind" -NOT mpd!
-approx. 1% of population
-chronic, no cure ~ good ways to manage but no way to cure
-develops between early adolescence and mid-late 20s
*usually around 18-22 is 1st psychotic break
-earlier onset + longer it takes to fully develop = *HARDER* to treat!
-prodromal phase = period of time when u start to act "weird"
*longer = worse
-better to get psychotic very fast and very intensely ~ better prognosis
-biologically based/genetic predisposition
-traumatic events/drugs can TRIGGER predisposition -> NOT cause it!!

**MAJOR MENTAL ILLNESS**VERY HIGH SUICIDE RATE**

LIFE OF SUFFERING
POSITIVE Symptoms of Schizophrenia
*THINGS ARE PRESENT THAT SHOULDN'T BE PRESENT*
-Hallucinations:
*auditory! hear voices, growling, "God" and they're not saying nice things!
*if one smells or tastes things that aren't there = tumors
-Delusions: fixed, false beliefs
*non-bizarre - could conceivably be true (ex. FBI is watching me)
*bizarre - couldn't conceivably be true (ex. been abducted by aliens)
-Neologisms: "word salad"
-Paranoia: ppl are out to get me
-Distorted perceptions in general: time distortions, places etc.
NEGATIVE Symptoms of Schizophrenia
*THINGS ARE NOT PRESENT THAT SHOULD BE*

*Majors: 1st drugs listed above
Schizo Meds on NEUROTRANSMITTERS
DOPAMINE: psychotics have too much DA
-1st class of drugs worked on DA-2 receptors to block DA
-Acts on pos. symptoms of schizo.
SEROTONIN: too much SE~ believed to be due to studying LSD fx
-Atypical antipsychotics
*work on POS & NEG symptoms
-More of an impact on neg. symptoms
GLUTAMATE: related to SE
-indirect fx due to connection w/SE
PHENOTHIAZINES
-Accidentally found in 1950s
-Major tranquilizer
-1st/major drug = chlorpromazine (thorazine)
**WORK MAINLY ON DA(-2) receptors**
-GREAT at txing pos. symptoms, no fx on neg.s
-Fx on:
*limbic system (emotional-fear, emotion etc)
Side Fx of Phenothiazines
1) Brain stem: suppress vomit reflex, suppress respiration
2) Bailganglia: (DA-rich part of mid-brain, motor fx)
-looks like parkinsons (tremors)
EXTRA PARMETAL Symptoms (EPS): [caused by medication, not illness]
*akathesia (constantly jumping out of skin)
*dystonias (random involuntary movements)
*parkinson-like (tremors, poor balance)
If you experience EPS:
-stop meds and become psychotic again
-take other meds to balance (polypharmacy)

*much more efficient via IV or IM
Haldoperidol (Haldol):
*very good antipsy. fx
*cause a lot of BPS/side fx
*orally, IM, IV - oral side fx worst, IV best
*acute psychosis, delerium - will clear delerium but must use in right way.
ATYPICAL ANTIPSYCHOTICS

*PROFOUND EFFECTIVENESS!*
-makes them verbal, talkative, affective - wouldn't know they were schizo!-
Side Fx of Clozapine
-intense weight gain, constipation, tends to make you drool
-sedating
-withdrawal symptoms if stopped abruptly
