25
What are the 3 key domains of PTSD symptoms
Re-experiencing Avoidance Hyperarousal
25
PTSD re-experiencing symptoms include
Flashbacks Memories Repetitive thoughts/nightmares
26
PTSD avoidance includes
Avoiding people/situations related to trauma
27
PTSD can also cause negative cognition such as
Self harm, substance abuse Depression and anxiety Numbness, anhedonia Headaches, dizziness, GI upset
27
PTSD hyper-arousal includes
Easy to startle Insomnia Hypervigilance Irritable/restless
28
PTSD investigation
Trauma screening questionnaire
28
PTSD sub threshold management
Watchful waiting if mild symptoms within a month of trauma | Arrange within 1 month - add follow up at 1 month to see progress
29
PTSD mainstay management
- Trauma focused CBT - EMDR used in more severe cases - Drug treatment if psychological therapy declined/not responded to
30
PTSD drug managment
SSRI or venlafaxine. Last resort = antipsychotics e.g. risperidone if non responsive.
31
Acute stress reaction vs PTSD
Much more rapid onset than PTSD. Doesn't last longer than 1 month.
32
Possible presentation of acute stress reaction
Initial state of daze (tunnel vision, not responding to stimuli, disorientation), followed by either further withdrawal or a state of agitation/anxiety - can get autonomic features of anxiety e.g. flushing, can also get partial amnesia
33
Management of acute stress reaction
* Support and reassurance * Trauma focused CBT * Benzodiazepnes may be used for short term distress | Self limiting condition - benzos don't prevent PTSD
34
X is not recommended for management of acute stress reaction
Psychological debriefing following trauma - can increase the risk of developing PTSD
35
When does adjustment disorder need to occur
Within 3 months of change, doesn't last more than 6 months.
36
Adjustment disorder management
Support, reassurance - maybe psychotherapy in the form of CBT or group therapy.
36
Symptoms of adjustment disorder
Symptoms of anxiety and depression may coexist but they will be subclinical so that neither diagnosis can be made.
37
OCD investigation
Yale brown obsessive compulsive scale
38
mild OCD management
Low intensity psychological interventions: brief CBT (10 hours- either individual self-guided or group), including ERP
39
moderate OCD management
More intensive CBT including ERP or can use drugs - SSRI
40
What does ERP involve?
Aims to allow anxiety to habituate: we trigger anxiety through introducing the obsession/thought to the patient, instead of engaging in the compulsion, they experience the anxiety. They learn to adjust to this and then we scale up the obsession trigger.
41
What pharmacotherapy is recommended in OCD
SSRI = first line. If they don't work after 12 weeks we can trial alternative SSRI or clomipramine (TCA)
42
How does pharmacotherapy differ in OCD compared to depression
SSRI requires 12 weeks opposed to 4-6 weeks to see effects in OCD, larger dose also required therefore weaning of SSRIs in OCD needs 12 months rather than 6
43
Panic disorder investigations
- TFT - hyperT - Depression screen - if depression precedes, it is not panic disorder - UDS - substance use - ECG - MI - BM - hypo
44
Panic disorder management
1. Recognition and diagnosis 2. (mild-moderate). Primary care treatment: individual self help and information about support groups 3. (moderate-severe): CBT + SSRI. 4. 2nd line = imipramine or clomipramine (trial for 12 weeks) 5. Refer to specialist MHS if 2 interventions trialled
45
Phobias, encompass [1,2,3] represent a cluster of anxiety disorders characterized by excessive and irrational fears.
Specific phobia, social anxiety disorder (SAD), and agoraphobia
46
What is needed for OCD diagnosis
* Presence of obsessions, compulsions, or both. * Time-consuming (more than one hour a day) or causes significant impairment. * Not attributed to another medical or mental disorder.
47
What are obsessions
Unwanted intrusive thoughts or images that are egodystonic and cause distress
48
What are compulsions
Repeated stereotyped rituals that the individual feels the need to do in order to suppress their anxiety - they can be covert or overt.
49
OCD prognosis
Runs a chronic course, with symptoms worsening at times of stress. Without treatment, it is disabling; 50% of cases have comorbid depression.
50
What are phobias
Intermittent anxiety occurs in specific but ordinary circumstances. People characteristically avoid or escape feared situations, only seeking treatment when this becomes disabling.
51
What is agoraphobia
Fear of large open spaces where you are unable to get to safe place (home)
52
Agoraphobia onset
20s- mid 30s - may be gradual or precipitated by sudden panic attack
53
Typical presentation of bad agoraphobia
Patient is housebound with close circle of family and friends. Comorbid depression = common
54
What is social phobia
Social anxiety disorder = fear of being judged by others. People worry that they will embarrass themselves in public.
55
Social phobia vs agoraphobia
- With social phobia, patients can cope in the agoraphobia situations e.g. large crowds, as long as attention is not on the. ∴ they tolerate smaller situations e.g. dinner parties less well. Patients often worry about particular symptoms e.g. blushing. - Social phobia also has a slightly earlier diagnosis than agoraphobia.
56
What is the main symptom of phobias
Avoidance is the main symptom, where this is not possible, the person experiences disabling anxiety.
57
What is the mainstay of phobia management
Graded exposure therapy
58
What is graded exposure therapy
Utilizes systematic desensitization, based on the principle that anxiety habituates and doesn't last more than 45 minutes ish. There you build up a tolerance over sessions with an increasing stimulus of the phobia
59
How is social phobia usually managed
Normally the patient engages in SSBs and active monitoring to avoid embarassment. Therapy focuses on dropping SSBs and confronting (exposure therapy) social situations that challenge assumptions.
