Psychiatry is the bestSAM TOPP CT1 IN HOUNSLOW

Tonight

u History taking/MSE/formulation/PACESu Psychotic disorders u Bipolar affective disorder u Anxiety disorders u Personality disorder

History taking u Takes a lot longer than you have in PACESu Think general history but a bit spicier u PC u HPC u PMHu Past psychiatric history - include admissions and if informal or under MHAu DH - think about medication side effects, what has/hasn’t workedu FH u Forensic history - convictions u Childhood and personal history – pregnancy/birth, upbringing, school,

relationshipsu Social history - job, benefits, housing, smoking, drugs, alcohol

History taking

u Be curious u Think about the symptoms /signs you are eliciting and what they

meanu Let the patient do the work u Don’t be scared of silence u Psychosis – patience, rapport, gently probe delusions u Mania – formal, boundaries, may need to interrupt u Depression – patience, kindness u Anxiety – focus on the effects it has on their life

Risk

u To selfu Self-harm/suicide

u Self-neglect – self-care, nutrition, physical health

u Adherence with medication

u To others u From others

u Vulnerability, retaliation

u Property u Absconding

Descriptive psychopathology

u Delusions u Fixed, unshakable beliefs, irrespective of counter-argument, that are

unexpected and not in-keeping with a patient’s cultural background

u Delusional perceptionu I saw the traffic lights turn green and I knew I had to rid London of capitalism

u Mood congruent u Seen in affective psychoses – e.g nihilistic (rotting insides) in depression or

grandiose (Jesus) in mania

Differential diagnosis

Formulation and treatment

u Predisposing u Precipitating u Perpetuating u Bio-psycho-social approach

Schizophrenia and related psychoses

u Psychosis is an umbrella term, schizophrenia is a specific psychotic disorder

u Fundamentally a distortion in thinking and perception

Paranoid schizophrenia F20.0u At least one of the following

u Thought interference – insertion, withdrawal, broadcasting u Delusions of control (passivity); delusional perception

u Auditory hallucinations – 3rd person/running commentary

u Or at least two of the followingu Persistent hallucinations in any modality u Catatonic behaviour

u Breaks in the train of thought – incoherent speech, neologisms u Negative symptoms – paucity of speech, withdrawal, loss of interest, blunting

u Duration of at least one monthu Should not be diagnosed in presence of overt brain disease or during states of

intoxication/withdrawal

Other subtypes

u Hebephrenic schizophrenia

u Disorganised speech and behaviour, flat affect, rapid development of negative symptoms, poor prognosis

u Catatonic schizophrenia

u Prominent psychomotor disturbances between extremes of hyperkinesis and stupor and negativism/posturing

u Simple schizophrenia

u Negative symptoms gradually arise without acute episode (no delusions or hallucinations)

u Residual schizophrenia

u Previous positive symptoms less marked, negative symptoms more prominent

u Post-schizophrenic depression

u Depression in aftermath of illness. Must still have psychotic symptoms but depression dominates. Increased risk of suicide

Disorders related to schizophrenia

Schizoaffective disorder

• Schizophrenic and affective symptoms present simultaneously for at least 2 weeks

• No separate episodes of schizophrenia and affective disorders or drug use

• Treat as for schizophrenia +/-mania/depression

Schizotypal disorder

• Odd beliefs, magical thinking• Ideas of reference • Odd/eccentric behaviour, no close

friends • Suspiciousness/paranoid ideas• No delusions/hallucinations

Differential diagnosis

u Organic causes – e.g infection, inflammation, malignancy u Acute and transient psychotic disorder (time)u Mania/depression with psychotic features – congruent delusionsu Delusional disorder (no other psychotic symptoms present)

Epidemiology

u Lifetime prevalence: 15-19 per 1000 u Male:female equal u Earlier average age of onset for males (23vs 26 years)u 20% reduction in life expectancy (10-15 years)u Suicide most common cause of premature death u Significant comorbidity: metabolic syndrome, substance misuse

Cause

u Genesu Identical twin 46%, one sibling 12-15%

u Environment u Complications in pregnancy/childbirth/neonatal period

u Delayed walking and neurodevelopmental problems

u Severe maternal malnutrition

u Maternal influenza in pregnancy

u Degree of urbanisation at birth

u Use of cannabis, esp during adolescence

Pathophysiology

u Too much dopamine u Not enough glutamine u Too much serotonin u Too much noradrenaline u Not enough GABA

Treatment

u Think bio-psycho-social!u All adults following first episode of psychosis

referred to Early Intervention in Psychosis u Intense, specialist outpatient service for 3 years u Care-coordination u Medical reviews with psychiatrist and treatment

with antipsychotic medicationsu Physical health checks u Psychological intervention – CBTpu Support and education for families – carer’s

assessment, family therapy, psychoeducationu Support with employment/educations u Support with social care – housing/finance issuesu Relapse prevention

Antipsychotics!

u First generation u Chlorpromazine (first ever)u Flupentixol

u Haloperidol u Sulpiride

u Second generation u Amisulrpideu Aripiprazole

u Olanzapineu Quetiapine

u Risperidone u Lurasidoneu Caripirazine

u Clozapine

Antipsychotics

u Weird classification u FGA: more associated with EPSEs, akathisia, raised prolactin, tardive

dyskinesia, prolonged QTcu SGA: more associated with metabolic side effects u Little difference between efficacy EXCEPT clozapine u FGA role in rapid tranquilisation (e.g haloperidol) and depot

preparation (e.g flupentixol) u Right drug for the patient

What if it doesn’t work?

u If after 4-6 weeks of treatment at therapeutic dose there is no response, should change antipsychotic (if FGA, should try a SGA)

u If after a further 4-6 weeks at therapeutic dose there is still no response, CLOZAPINE (if no CI)

Common antipsychotics

u Aripiprazole – D2 partial agonist (weak 5-HT1a partial agonism and 5-HT2A antagonism)u Lovely side effect profile – lack of weight gain/sedation/prolactin/QTc,

available as depot

u BUT, can cause agitation and takes 2 weeks to work orally

Common antipsychotics

u Risperidone – D2, 5-HT2A, alpha1 and H1 antagonistu Available as depot (palliperidone)

u BUT weight gain, EPSEs, prolactin

Common antipsychotics

u Olanzapine – D1, D2, D4, 5-HT2, H1, muscarinic antagonist u Very effective (maybe marginally better than other SGAs), minimal

akathisia/prolactin

u BUT sedation, weight gain, metabolic L

Common antipsychotics

u Quetiapine – D1, D2, %-HT2, alpha1 and H1 antagonist u Limited EPSEs/prolactin

u BUT sedation, weight gain

QTc

u Prolonged QTc à torsades de pointes u Regular ECG monitoring

EPSEs

u Parkinsonismu Days to weeks

u Tremor, bradykinesia

u Reduce dose, consider switch, consider procyclidine (anticholinergic)

EPSEs

u Acute dystoniau Within hours

u Uncontrolled muscle spasm: oculogyric crisis, torticollis

u Procyclidine IM/IV

EPSEs

u Akathisia u Hours to weeks

u Restlessness (risk for suicide)

u Reduce dose, consider switch, consider propranolol, benzo, mirtazapine

EPSEs

u Tardive dyskinesia u Months to years, may be reversible

u Abnormal involuntary movements, e.g lip smacking

u Stop procyclidine if taking, switch antipsychotic (clozapine may be the best)

Neuroleptic malignant syndrome

u Life threateningu Mental state change, fever, rigidity, autonomic dysfunctionu Raised CK on bloodsu Stop antipsychotic, get help quickly - ITU

Clozapine

u Mainly blocks D1 and D4, also anti-cholinergic, histaminergic, serotonergic and adrenergic activities

u Smoking lowers plasma concentrations, caffeine increases

u CI – neutropenia, other blood dyscarasias, myocarditis/pericarditis/cardiomyopathy, severe renal, cardiac or liver disease

Monitoring
