  2. Neurotic Disorders- Scene Setting RCPsych ILOs 1, 2: Identify, diagnose & formulate 3, 4, 5: Investigate, Manage & Refer Concept- Evolution of neurosis/ anxiety Epidemiology, C/F, Diag. Criteria, D/D Aetiology & Management Principles 3 case studies- 4 groups, 3 minutes on each case, correct answer- 10 points, wrong – 0 2 scorers, 4 major mental disorders MCQs- Shout 1st & 10 for right & - 5 for wrong
  3. Neurosis/Anxiety- Concept Neurosis/ Anxiety ? Worry (N, Webster/ Oxford Dictionary) Stress Normal vs. abnormal State vs. trait Episodic vs. Pervasive Situational vs. Generalized Internal (Active) vs. Reactive
  4. Anxiety (Neurotic) Disorders: Relevance Prevalence: General Population ‘Symptoms- common in gen. population High Comorbidities May present with physical symptoms Proper recognition for appropriate treatment Management- combined approach
  5. Anxiety (Neurosis)- History Greek: 3 Humors Dark age: spirits/ divine punishments ‘Hysteria’ – Hippocrates (15th-16th Cent.) ‘Neurosis’- William Cullen (1777) ‘Studies in Hysteria’- S. Freud (1895) Psychoanalytical - repression, topological mind, fixations, defense mechanisms WW I → ‘Emotional’ vs. ‘Physical’, ‘Conversion Hysteria’ or ‘Phobic Neurosis’
  6. Anxiety (Neurosis)- History….. ‘Emergency Reaction’- Waltor Canon (1920s)- ‘Fight or Flight’ response via ANS “Conditioning’- John Watson (1930s)- traumatic learning situations ‘Instrumental Conditioning’- Mowrer (1940s)- ‘reinforcers’ & ‘desensitization’ Canon Bard Theory (HPA axis) Tranquilizers- Benzos, Antidepressants Imaging: Frontal cortex & B/L Caudate in OCD, Temporal lobes- Panic →TLEs

  15. GAD- Treatments Psychological: less effective than in other anxiety disorders, CBT useful- education, cognitive remediation. BT- exposure, relaxation, control of hyperventilation. Physical: ECT/ Psychosurg.- rare (severe intractable) Pharmacological: directed towards symptom domains: Psychic- buspirone Somatic- benzos Depressive- TCAs, SSRIs, SNRIs, Mirtazepine, MAOIs ANS/CVS- β blockers

  19. Obsessive Compulsive Disorders Essence: a common chronic condition with obsessions &/or compulsions causing severe distress . Clinical features:
  20. OCD…. Types: Check(63%), wash(50%), contamination (45%), doubt(42%), bodily fears (36%), count (36%), symmetry (31%), aggressive (28%) Epidemiology: Age- 20yrs, F=M, Prev. – 0.5-2% Associations: Cluster C (40%), anankastic traits (5-15%), Schiz.

  22. OCD- Aetiology Theories: Neurochemical: 5HT dysregulation, 5HT/DA interaction Immunological: CMI (against basal ganglia peptides) Imaging: CT/MRI- B/L reduction in caudate size PET/SPECT- hypermetabolism in orbitofrontal gyrus & BG Genetic: MZ: DZ= 50-80:25%, 3-7% 1st degree relatives Psychological: Defective arousal & / or inability to control unpleasant, obsessions -conditioned stimuli, compulsions- reinforced learned behaviours Psychoanalytical: regression, isolation, undoing & reaction formation

  27. Post Traumatic Stress Disorder (PTSD) Essence: Severe psychological disturbance following a trauma, involuntary re-experiencing with symptoms of hyperarousal, avoidance & emotional numbing. Symptoms/Signs: Onset within 6/12 (ICD10) of trauma, at least 1/12 with clinically significant distress or impairment in social, occupational or other important areas; 2 or more ‘persistent symptoms of ↑sed psychological sensitivity & arousal: Initial/ middle insomnia Irritability/ anger outbursts Poor concentration Hypervigilance ↑sed startle response
  28. PTSD- Aetiology Psychological: ‘Remodeling of Underlying Schemas’- requires holding of trauma experience in ‘active memory’ (working through). Dissociation protects from being overwhelmed. Biological: Neurophysiological changes → permanent neuronal changes (chronic/ persistent stress/ reliving). Neurotransmitters- NA/ 5HT/ GABA/ Endogenous opioids / glucocorticoids. Neuroimaging: ↓sed R hippocampal vol., dysfunction of amygdala & associated projections- ↑sed fear response Genetic: Higher concordance in MZ > DZ twins
  29. PTSD….. Epidemiology: Risk of PTSD (20-30%), Median(8-13%), Lifetime prevalence-7.8%, F: M= 2:1, Cultural differences + Risk factors: Vulnerability: low education, low SE class, Afro-Carribean /Hispanic, Female, low self esteem / neurotic traits, past/ family h/o psychiatric problems, previous traumas (CSA). Comorbidity: Depression, mood disorder, D & A, somatisation disorders. D/D: ASR/ D, Enduring personality change, adjustment dis., other anxiety dis., depression, mood disorder, OCD, schiz., D & A.
  30. PTSD- Management Psychological: CBT: TOC- education, self monitoring, anxiety management, exposure, cognitive restructuring EMDR: Voluntary multisaccadic eye movements Psychodynamic: meaning & work through Phramacological: limited evidence, for comorbid Depression: SSRIs/TCAs/MAOIs Anxiety: Benzo/buspirone/ ADs Intrusive thoughts: CBZ, Li, Fluvoxamine
  31. PTSD- Course & Outcome 50% recover in 1 yr, 30% chronic course Outcome dependent on initial symptom severity Recovery helped by: good social support, absence of maladaptive coping, no further traumas, no D&A/Forensic
