⚕️ FREE MSRA PODCAST – Psychosis🎧 A clear, high-yield breakdown of this severe mental health condition affecting perception and reality – perfect for exam prep and real-life clinical scenarios.🧠 Key Learning Points📌 Definition• Psychosis is a mental health condition characterised by a disconnection from reality, often involving hallucinations, delusions, and disorganised thinking. It significantly impairs a person’s ability to function.📌 Causes & Risk Factors• Primary psychiatric conditions (e.g. schizophrenia, bipolar disorder)• Severe depression (psychotic depression)• Substance misuse – particularly cannabis, LSD, cocaine• Neurological conditions – e.g. Parkinson’s disease, brain tumours• Family history of psychotic disorders• Childhood trauma, social isolation• Medical causes – neurosyphilis, HIV, space-occupying lesions• Mnemonic: "S.C.A.R.E.D.":Substance misuseConditions (neuro, infectious)Affective disorders (depression, bipolar)Risk factors (family history, trauma)Early onsetDelusions/hallucinations📌 Pathophysiology• Dysregulation of dopamine and glutamate in brain circuits• Structural and functional brain abnormalities (e.g. prefrontal cortex, limbic system)• Abnormal signal processing leads to altered perception, delusions, hallucinations📌 Symptoms• Positive symptoms: hallucinations (esp. auditory), delusions, disorganised speech/behaviour• Negative symptoms: social withdrawal, reduced motivation, blunted affect• Cognitive symptoms: impaired memory, attention, executive function• Associated: agitation, aggression, depression, self-harm thoughts• Mnemonic: "HDD-NAC"HallucinationsDelusionsDisorganised thinkingNegative symptomsAggressionCognitive deficits📌 Differential Diagnosis• Mood disorders with psychotic features (e.g. severe depression, mania)• Substance-induced psychosis• Delirium• Dementia• Medical conditions (e.g. infections, brain tumours, endocrine disorders)📌 Diagnosis• Clinical history + mental state exam• Symptom-based diagnosis – no single confirmatory test• Investigations to exclude organic causes:FBC, LFTs – check for alcohol misuseSerology – rule out syphilisHIV screeningUrine drug screen – detect recreational drugsCT brain – if focal neurological signs present• Tip: CT is not routine, only used if structural lesion suspected📌 Management• Antipsychotics – risperidone, olanzapine (first-line)• Mood stabilisers – lithium or carbamazepine (if bipolar-related)• Psychological therapies – CBT, family therapy• Hospital admission – if high risk or impaired insight• Early intervention teams crucial for first-episode psychosis• Compulsory treatment may be needed under UK Mental Health Act• Always address substance misuse and ensure family involvement in care📌 Complications• Social/occupational deterioration• Suicide risk• Substance dependence• Homelessness• Physical comorbidities• Persistent disability if untreated📌 Prognosis• 80% respond to treatment within 1 year• Only 20% remain relapse-free at 5 years• Poorer prognosis: early onset, long untreated duration, male gender, negative symptoms, low social support, continued substance misuse• Relapse is common, hence long-term treatment and monitoring are essential📎 More MSRA Resources for Psychosis📝 Revision Notes: https://www.passthemsra.com/topic/psychosis-revision-notes/🧠 Flashcards: https://www.passthemsra.com/topic/psychosis-flashcards/💬 Accordion Q&A Notes: https://www.passthemsra.com/topic/psychosis-accordion-qa-notes/🚀 Rapid Quiz: https://www.passthemsra.com/topic/psychosis-rapid-quiz/🎓 Full Course: https://www.passthemsra.com/courses/psychiatry-for-the-msra/Hashtags#MSRA #MSRARevision #MSRATextbook #MSRAQuiz #MSRAQuestionBank #MSRAFlashcards #MSRAQ&ANotes #MSRAAccordions #MultiSpecialityRecruitmentAssessment #MSRAOnlineRevision #MSRARevisionWebsite #Psychiatry #Psychosis
