25
Benzodiazepines Concerns/Benefits
Abrupt withdrawal may cause psychosis, delirium, confusion, seizures, insomnia and agitation
26
Anticonvulsants Concerns/Benefits
Discontinuation symptoms and abuse have been reported
27
SAD
Symptoms related to social or performance (as opposed to broad in GAD) situations in which you expect scrutiny or evaluations by others Affects 6% of adults
28
SAD Generalized vs non-generalized
Generalize (70% of cases), pervasive social fears and avoidance, early onset, familial, high comorbidity, more impairment, low remission, continual treatment (non-generalized is opposite)
29
SAD Treatment
Medication equally as effective as CBT (high effectiveness over year when used together) CBT produces more significant results with lower rates of relapse; meds preferred if paralyzing symptoms or comorbid severe depression
30
SAD Treatment Plan
1st Line: SSRI 2nd Line: Different SSRI or SNRI (venlafaxine, mirtazapine); add benzo short term, augment with buspirone or beta blocker (for performance anxiety) 3rd Line (SGA - quetiapine, risperidone; MAIO - phenelzine; anticonvulsant/mood stabilizer - pregabalin, gabapentin)
31
Other treatment options for SAD
Combining meds (buspiron w/ SSRI or SNRI; Benzo with SSRI or SNRI; Med with CBT better than two meds) Gabapentin is only modestly effective Beta blockers ONLY for performance anxiety Antipsychotics (quetiapine, risperidone) for cognitive impairment, weight gain and metabolic issues
32
PTSD Diagnostic criteria
History of exposure to traumatic event with attributes from each cluster: Exposure (direct, indirect) Intrusion (nightmares, flashbacks) Avoidance of situations Cognition and mood (recall problems, memory deficit) Arousal and reactivity (irritable, aggressive, sleep disturbance) Symptoms must last longer than 1 month, can't be attributable to substance or co-occurring medical conditions
33
PTSD Common Reactions/Behaviors
Fear, helplessness, anxiety Reliving trigger events in form of thoughts, flashbacks or dreams Disassociation Avoidance Hyperarousal and exaggerated startle resposne Occurs on a continuum with some living their entire lives in a subthreshold PTSD state
34
Common PTSD Comorbidities
Substance abuse, traumatic brain injury, suicide, pain, major depression, PTSD
35
PTSD Treatment
Psychotherapy w/ or w/o medication (exposure therapy, CBT, stress inoculation, eye movement desensitization and reprocessing) Alternative medicine therapy (CBT with pool, massage therapy, meditation, yoga, art therapy, marital/family therapy and acupuncture) -->more effective than lifelong disability
36
PTSD Medication
First Line (SSRI or SNRI or TCA) Mood stabilizer (Depakote, Tegretol, Gabapentin) Antipsychotic (Olanzapine, Risperidone, Quetiapine) Nightmares (Clonidine, Prazosin) Sleep (Trazodone, doxepine, nefazodone, mirtazapine)
37
Special PTSD Medication Considerations
Avoid benzos due to lack of effect on PTSD symptoms and abuse potential Gabapentin, divalproex, augmented SSRI with atypical antipsychotic all useful in treatment-resistant cases Avoid opiates/abusable medications
38
Anticonvulsants for PTSD
Valproate, Carbamazepine, Lithium (good evidence) Gabapentine, Pregabalin (modest improvement) Tiagabine (not proven) Lamotrigine and Topiramate (not proven)
39
Atypical Antipsychotics for PTSD
Risperidone and Olanzapine (inherent anti-anxiety and antidepressant effects w/ 5HT2 and 5HT1A activity; high limbic activity; some effectiveness for intrusive thoughts and flashbacks; SE include weight gain, akathisia and sedation leading to high drop outs) Quetiapine (possibly effective in treatment resistant PTSD; most useful if psychosis)
40
PTSD nightmare medications
Clonidine and Prazosin Alpha-adrenergic activity associated with fear and startle response Clonidine is centrally acting alpha 2 agonist resulting in reduced sympathetic outflow from CNS; reduces severity and duration of nightmares and improves quality of sleep Prazosin acts peripherally and centrally as an alpha-1-adrenergic blocker; low doses (1mg) helpful within 7 days
41
OCPD
Obsessive compulsive personality disorder characterized by (must have 4): Excessive need for perfect, preoccupation with details, excessive devotion to work, rigidity of morals or values, inability to get rid of items that no longer have value, miserly or stingy, reluctance to work with others
42
OCP and OCPD Treatment
Psychotherapy No medication unless physical or mental illness accompanies
43
OCP
Obsessive compulsive personality (strong values of order, organization, cautious, obeying rules)
44
OCD
Obsessive Compulsive Disorder Anxiety disorder rather than a personality disorder at which you experience recurrent obsessions and compulsions
45
OCD Diagnostic Criteria
Must have obsessions and compulsions that significantly impact daily life Patient usually realizes these are excessive compulsions; obsessions must be intrusive and persistent and include images that cause distress; compulsions must include excessive and repetitive or ritualistic behavior
46
Common OCD Obsessions
Germs or dirt, intruders, preoccupation with violent acts, unwanted sexual images and acts, unwanted religion thoughts, neatness or symmetry, continual thinking of certain words/sounds/images/numbers
47
OCD Compulsions
Behaviors that patient feels they must carry out over and over Behaviors which provide order and symmetry Behaviors aimed at getting rid of anxiety or to stop a feared situation Have unrealistic solutions
48
OCD (vs OCPD)
Obsessions and compulsions known to be problematic and non-beneficial (no obsessions or compulsions) Use tasks to reduce anxiety caused by obsessive thoughts (justify tasks as being beneficial) Medication used for Tx (no meds for Tx)
49
Borderline Personality Disorder
Often caused by childhood sexual trauma Verbal abuse by mothers increases likelihood
50
Antisocial Personality Disorder
Environmental/parental Lack of fathers affection or lack of boundaries in early childhood increase risk
51
Anxious Personality
High reactivity - sensitive to light, noise, texture or other stimuli Likely to develop anxious personalities
52
OCD Non-Pharm Treatment
Psychotherapy (CBT; ERP - exposure and response prevention) Relaxation
53
OCD Pharm Treatment
Antidepressants Step 1: Fluvoxamine or Clomipramine, or other SSRI/SNRI Step 2: If no partial response, choose different SSRI or TCA Step 3: SSRI/TCA + Mirtazapine or atypical antipsychotic Step 4: SSRI + Clomipramine OR SSRI/TCA + Buspirone OR SSRI?TCA + Pindolol
54
OCD Treatment for Resistant Cases
70% respond to CBT with or without medication ECT not effective - consider transcranial magnetic stimulation or deep brain stimulation Riluzole used to lower high brain glutamate levels (Memantine also does this) N-acetylcycsteine may be used as antioxidant
55
Define Panic Disorder
Spontaneous and unexpected occurence of panic attacks (4 or more in a 4 week period OR 1 followed by at least 1 month of fear of another attack) Intense fear with abrupt onset of 4/13 symptoms with peak less than 10 minutes from onset
56
Panic Disorder Diagnostic Symptoms
Palpitations, pounding heart or increased HR Sweating Trembling or shaking Sense of SOB or smothering Feeling of choking Chest pain or discomfort Nausea/abdominal distress Feeling dizzy, unsteady, lightheaded or faint Derealization or depersonalization Fear of losing control or going crazy Fear of dying Numbness or tingling Chills or hot flashes
57
Panic Triggers
Injury, illness, conflict, use of cannabis, use of stimulants, SSRI discontinuation
58
Describe panic attack
Patients have urge to flee or escape and have sense of impending doom After attack they worry about next attack or going crazy, avoid situations or locations and are more passive/withdrawn
59
Panic attack comorbidities
Alcohol use, increased suicidality 80% have some other psychiatric disorder and 50-60% have depression Association between panic disorder and psychiatric disorders in first-degree relatives Medical comorbidities include: IBS, migraines, COPD, asthma, mitral valve prolapse, cardiomyopathy, restless leg syndrome, epilepsy and fatigue
60
Neurotransmitter targeted in panic disorder

Panic Disorder Treatment
CBT is best choice SSRIs and SNRIs | TCAs | MAIOs | Benzos
62
