  9. Model for managing treatment Summary • Talk, negotiate, dialog (therapeutic alliance, psychoeducation) • Informal  formal (?MHA use) • Period of observation (best before initiating treatment) • Medication – if required • Least toxic, least dose, shortest length (as possible) • Talking therapies • Counselling, CBT, psychotherapy, IP therapy, Group • Follow up • Review, optimise therapy • Aftercare - CPA (Care Programme Approach) • maintain therapeutic alliance, psychoeducation

  10. Prognostic factors

  11. Multi-Disciplinary Team work (MDT) • Basis of psychiatric diagnosis, treatment and management • Consensual decisions (most times) • Good communication skills • Important to include patient & carer in decisions • All professional have stake in patient care • Doctors, ward staff, OT, psychologists, pharmacists, community staff, any other therapists working with patient • Their concerns and views to be considered & documented • Final decision – ALL to be in agreement (if possible) thereby sharing risk and responsibility • Care plan – jointly appraised, agreed and maintained • Medical staff have overall responsibility (RMO status) • This is currently under review by DHS

  18. Schizophrenia • Fundamental & characteristic distortions of thinking & perception • Inappropriate or blunted affect • Delusions (secondary) & Perplexity common • Onset Acute or gradual • M=F - Later onset in women • Genetic component • 1 parent affected  13% risk in kids • Both parents  46% risk in kids • 1 sibling affected  10% in other siblings • MZ twins  48% concordance • Life events & expressed emotions associated with relapses • CT changes – predate illness • Smaller temporal lobes by 15-20% & Enlarged ventricles • PET scans  functional disturbances in frontal & temporal structures • Cognitive changes – late feature generally

  19. Schizophrenia First rank symptoms • 3rd person auditory hallucinations • Running commentary • Thought echo • Made feelings ) • Made impulses ) • Made actions ) Passivity • Thought insertion ) ) Phenomena • Thought withdrawal ) Thought ) • Thought broadcasting ) Alienation ) • Somatic passivity ) • Delusional perception

  23. Schizophrenia - management

  24. Schizophrenia - Management Summary Therapeutic alliance MHA use if appropriate MDT decisions Reduce stressors Support – psychological, psychoeducation, reduce EE Drugs: Antipsychotics Anxiolytics Antidepressants Hypnotics (to aid sleep)

  25. Schizophrenia - Antipsychotics Summary Therapeutic alliance Most appropriate choice – clinical basis Atypicals 1st line in new cases (NICE) - Start low and increase as tolerated - Raise dose to therapeutic level - If no response in 4-6 weeks, consider change, seek help - Watch for side-effects Side-effects; - Drowsiness, wt gain ) Reduce dose, another - reduced blood pressure ) drug to counter effects, - EPSE ) change to another - Sexual dysfunction ) Non-compliance - Consider depot medication Treatment resistant (inadequate response to two a/p) - Clozaril (regular FBC, co-ordinated via CPMS – Clozaril Patient Monitoring Service)

Depression – Use of Antidepressants • Discuss choice of drug with the patient • Therapeutic effects, adverse effects, discontinuation effects • Start ANTIDEPRESSANTS • Titrate to recognised therapeutic dose • Assess efficacy over 4-6 weeks • Continue for 4-6 months at full treatment dose • Consider long-term treatment in recurrent depression • If no effect • Increase dose (to maximum dose if tolerated) & assess over 2/52 • Try another antidepressant from another class • Titrate as above • Little improvement  Treatments for refractory depression

  30. Bipolar Affective Disorder (BPAD) • >=2 episodes of mood/activity changes • Recovery complete between episodes • M = F • Usually abrupt onset of mania • Manic episode – last median of 4 months • Depressive episode – last median of 6 months • Often follow stressful life events • First episode  occur at any age (Most freq bet 20-29 years) • Increasing age  Increased frequency & length of episodes • 1-2% of population at some point in their lives • Genetic predisposition • BPAD  11% risk of Depression (UP) in 1st degree relatives • BPAD  8% risk of BPAD in 1st degree relatives • Morbidity & mortality is HIGH  suicide/accidental deaths/concurrent illnesses

  31. Bipolar Affective Disorder (BPAD) Features Elated mood Grandiose ideas & inflated self esteem Increased energy & activity Flight of ideas Pressure of speech Increased libido impaired judgement & impulsive behaviour Reduced need for sleep Increased creativity Impaired attention & concentration Psychotic symptoms

  46. Dementia – Alzheimer’s Disease Features - Primary degenerative brain disease - Usually in later life, but can occur earlier - Early onset  +ve FH, rapid course, prominent features of temporal and parietal lobe dysfunction - Down’s Syndrome  increased risk of AD - May be associated with vascular dementia - Memory problem is main feature - 1% at 65y, 10% at 80y, 40% at 90y (Rule: doubling every 5 years) - Pathology: Marked reduction in population of neurones Neurofibrillary tangles Neuritic plaques Granullovacuolar bodies Marked reduction in enzyme choline acetyl-transferase - Diagnosis: - Presence of dementia (see previous slide for guide) - Insidious onset & slow deterioration - Absence of features of systemic & other brain disease - Absence of sudden onset

  47. Dementia Reversible causes of dementia These need to be excluded Hypothyroidism Hypercalcaemia Vitamin B12 deficiency Niacin Deficiency (Folate) Normal pressure hydrocephalus Subdural haematoma Syphilitic

  48. Dementia - Management • Refer Memory Clinic • Differentiate from delerium/depression/paranoid disorders • Look for treatable causes (previous slide) • Physical investigations • FBC/U&E/LFT/TFT/Gluc/VitB12&Folate/Syphilis serology/Ca&Phos/ESR • Urine analysis & culture • ECG & CXR • CT Brain • Mini Mental State Examination MMSE (Memory Clinic) • Treatment; Treatable causes Behavioural changes – non-pharmacological Drugs: Antidepressants Anxiolytics Antipsychotics Anti-cholinesterase Inhibitors (Memory Clinic) • Vascular Dementia – Reduce risk Manage BP Low dose aspirin (note bleeding potential) Surgical treatment of carotid stenosis
