PSYCHIATRY - DIAGNOSIS, SAFETY + PSYCHOPHARMACOLOGY
YEAR 3 | PAGE 64A - MSE / SAFETY -> SYNDROME -> TIMELINE -> EXCLUSIONS -> TREATMENT -> DISPOSITION
PSYCHIATRY SHELF / COMAT QUESTIONS ARE TIMELINE + SAFETY PROBLEMS. FIRST DECIDE WHETHER THE PATIENT IS DANGEROUS, DELIRIOUS, INTOXICATED / WITHDRAWING OR MEDICALLY ILL; THEN USE DURATION, FUNCTION AND THE MOOD-PSYCHOSIS RELATIONSHIP TO NAME THE SYNDROME. A. PSYCHIATRY FIRST-PASS REVIEW MAP
| Domain | Reasoning spine | Questions should force |
|---|---|---|
| MSE + safety | Appearance/behavior -> speech -> mood/affect -> thought process/content -> perception -> cognition -> insight/judgment -> suicide/violence risk. | Can the patient leave safely? Is emergency containment / medical evaluation needed before diagnostic refinement? |
| Mood + psychosis | Depression / mania -> psychosis relationship -> duration -> functional impairment -> substance / medical exclusions. | MDD with psychotic features vs bipolar vs schizophrenia-spectrum vs schizoaffective vs secondary psychosis. |
| Anxiety / trauma / OCD | Trigger/exposure -> symptom cluster -> duration -> avoidance/compulsions -> impairment -> comorbidity. | Normal stress vs disorder; panic vs GAD vs PTSD vs OCD; choose psychotherapy / medication logic. |
| Substance / sleep / eating | Intoxication vs withdrawal -> timing -> toxidrome / medical instability -> treatment; sleep/eating physiology and complications. | Recognize dangerous withdrawal, overdose, refeeding/electrolyte risk, and medical mimics. |
| Psychopharmacology | Drug class -> mechanism -> expected effect -> major toxicity / interaction -> monitoring -> syndrome the drug can mimic. | Serotonin syndrome, NMS, lithium toxicity, EPS/tardive dyskinesia, metabolic effects, withdrawal. |
PSYCHIATRY SHELF / COMAT QUESTIONS ARE TIMELINE + SAFETY PROBLEMS. FIRST DECIDE WHETHER THE PATIENT IS DANGEROUS, DELIRIOUS, INTOXICATED / WITHDRAWING OR MEDICALLY ILL; THEN USE DURATION, FUNCTION AND THE MOOD-PSYCHOSIS RELATIONSHIP TO NAME THE SYNDROME. A. PSYCHIATRY FIRST-PASS REVIEW MAP — 1. Safety and secondary causes come before the psychiatric label DEEP EXPLANATION A patient with agitation, hallucinations, depression or bizarre behavior may have primary psychiatric illness, delirium, intoxication/withdrawal, medication toxicity, neurologic
disease or another medical cause. The first task is therefore safety, attention/level of consciousness, vital instability and a focused search for secondary causes before assigning a chronic psychiatric diagnosis. WHY STUDENTS MISS IT Familiar symptom words such as "hallucinations" or "depressed" trigger pattern recognition too early, and learners can ignore fluctuating attention, autonomic signs or immediate self-harm risk. EASIEST CLUE Ask dangerous or secondary first? If attention fluctuates, vitals are abnormal, onset is abrupt or there is active self-harm/violence risk, pause the diagnostic timeline and address safety/medical causes.

PSYCHIATRY FIRST-PASS REVIEW MAP — 2. Psychiatric look-alikes are separated by timeline + function + mood-psychosis relationship DEEP EXPLANATION Many disorders share sleep change, low mood, agitation, psychosis or anxiety. Diagnostic discrimination comes from duration, degree of functional impairment, whether
psychosis occurs only during mood episodes or also outside them, and whether substances/medical disease better explain the syndrome.
WHY STUDENTS MISS IT Students memorize criteria in isolated lists but do not build a timeline, so vignettes with overlapping symptoms feel interchangeable. EASIEST CLUE Draw a one-line timeline: onset -> duration -> mood episodes -> psychosis inside/outside mood -> function -> exclusions. — 3. Psychopharmacology questions often hinge on toxicity, interaction or monitoring DEEP EXPLANATION Knowing the diagnosis is only half the question. Antidepressants, antipsychotics, lithium/mood stabilizers, anxiolytics and sedative-hypnotics can produce distinctive toxic
syndromes, metabolic effects, movement disorders, organ toxicity or dangerous withdrawal. Management choices therefore depend on mechanism plus patient-specific risk and monitoring.

EASIEST CLUE Draw a one-line timeline: onset -> duration -> mood episodes -> psychosis inside/outside mood -> function -> exclusions. — WHY STUDENTS MISS IT Learners pair one drug with one diagnosis but underlearn the adverse effect that makes an otherwise reasonable option wrong. EASIEST CLUE Before choosing a psych drug, ask: what can this cause, what must I monitor, and what dangerous syndrome can it mimic? B.
