Psych: Bipolar Disorder: Free MSRA Podcast

⚕️ FREE MSRA PODCAST – Bipolar Disorder🎧 A clear, high-yield breakdown of chronic mood disorder with alternating mania and depression – perfect for exam prep.🧠 Key Learning Points📌 Definition• A chronic psychiatric condition characterised by episodes of mania/hypomania and depression, leading to significant mood fluctuations and impairment.• Two types: Bipolar I (full mania ± depression) and Bipolar II (hypomania + major depression).📌 Causes & Risk Factors• Genetic predisposition (1st-degree relatives have 5–10× risk)• Neurochemical imbalances: serotonin, dopamine, noradrenaline• Environmental triggers: trauma, stress, substance misuse• Coexisting mental health disorders💡 Mnemonic: “GENES” – Genetics, Environment, Neurobiology, Events (stress), Substance misuse📌 Pathophysiology• Dysregulation of neurotransmitters (e.g. dopamine, serotonin)• Abnormalities in brain circuits regulating emotion• Changes in brain structure and function in imaging studies📌 Symptoms🔹 Mania:• Elevated/irritable mood, grandiosity, reduced need for sleep• Pressured speech, flight of ideas, impulsivity, risky behaviours• May involve psychosis (delusions, hallucinations)🔹 Hypomania:• Less severe than mania, no psychosis, minimal disruption to function🔹 Depression:• Low mood, fatigue, anhedonia, poor concentration, appetite/sleep changes💡 Mnemonic for Mania: “DIGFAST” – Distractible, Irresponsible, Grandiose, Flight of ideas, Activity ↑, Sleep ↓, Talkative📌 Differential Diagnosis• Major depressive disorder• Schizoaffective disorder, schizophrenia• Cyclothymia, borderline personality disorder• Substance-induced mood disorder• Medical causes: thyroid disorders, stroke, CKD, brain tumours• Medications: steroids, levodopa, isoniazid📌 Diagnosis• Based on ICD-10: requires ≥2 mood episodes, ≥1 being manic/hypomanic• Thorough psychiatric assessment essential• Rule out organic causes via:– FBC, U&Es, LFTs, calcium, TFTs– Toxicology screen– ECG, CT/MRI if needed– Lumbar puncture if CNS infection suspected• ECG mandatory before starting antipsychotics/mood stabilisers📌 Management🔹 Pharmacological• First-line: Lithium (long-term stabilisation)• Acute mania: Atypical antipsychotics (e.g. olanzapine, haloperidol)• Depression: Cautious antidepressant use (risk of switching to mania)• Rapid cycling: Lithium + valproate• Avoid: Gabapentin, lamotrigine (limited evidence), antidepressants alone🔹 Non-Pharmacological• CBT, family therapy, psychoeducation• ECT in severe treatment-resistant episodes• Lifestyle advice: sleep hygiene, avoid alcohol/drugs• Refer to CMHT if hypomania; urgent referral for mania/severe depression💡 NICE recommends avoiding long-term antipsychotics unless stabilisers fail📌 Complications• Suicidal ideation and attempts• Relationship and occupational breakdown• Substance misuse• Comorbid conditions: diabetes, cardiovascular disease• Impaired functioning, social withdrawal, self-neglect📌 Prognosis• Chronic, relapsing condition – requires long-term management• Poorer outcomes with psychosis, substance misuse, male gender• Suicide risk: 14–23× higher than general population• Lithium significantly improves outcomes in ~50% of responders📎 More MSRA Resources for Bipolar Disorder📝 Revision Notes: https://www.passthemsra.com/topic/bipolar-disorder-revision-notes/🧠 Flashcards: https://www.passthemsra.com/topic/bipolar-disorder-flashcards/💬 Accordion Q&A Notes: https://www.passthemsra.com/topic/bipolar-disorder-accordion-qa-notes/🚀 Rapid Quiz: https://www.passthemsra.com/topic/bipolar-disorder-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 #BipolarDisorder #Psychiatry #MSRAPsychiatry
