How to Take Notes in Abnormal Psychology: A Student's Complete Guide

Abnormal psychology is the course where the diagnostic criteria for different disorders overlap so much that the distinctions between them become the entire challenge. Major depressive disorder and persistent depressive disorder share many symptoms — the difference lies in duration and severity thresholds defined by the DSM. Generalized anxiety disorder and social anxiety disorder both involve excessive worry, but the context and triggers differ in specific ways that your professor explains verbally while referencing a dense slide of diagnostic criteria you are still trying to read.

Case study discussions are where the real exam material emerges, and they are the hardest to capture in notes. Your professor presents a patient vignette — a 22-year-old college student reporting difficulty sleeping, loss of interest in activities, and feelings of worthlessness for the past three weeks — and walks the class through the differential diagnosis. Is it major depression? Adjustment disorder? Bipolar II in a depressive episode? The professor's reasoning process, where they rule out one diagnosis after another based on specific criteria, is exactly what exams test. But this reasoning unfolds verbally in a discussion format that defies linear note-taking.

The verbal nuance problem is critical. Your professor says "the key distinction between OCD and generalized anxiety is that OCD intrusive thoughts are ego-dystonic — the patient recognizes they are irrational — while GAD worries feel realistic to the patient." That single sentence contains a high-yield exam distinction, but it was delivered as a casual clarification during a case discussion, not as a bullet point on a slide.

Abnormal psychology demands notes organized by disorder with explicit attention to differential diagnosis. Here are five strategies:

1. Create a disorder profile template and fill it in for every condition discussed. For each disorder, use a consistent format: Disorder Name, DSM Category, Key Diagnostic Criteria (minimum symptoms and duration), Differential Diagnosis (what it could be confused with and how to tell the difference), Etiology (biological, psychological, social factors), and Treatment (first-line and alternatives). Fill this in during lecture, focusing especially on the Differential Diagnosis section because that is what the professor's verbal explanations emphasize. Over the semester, this collection of disorder profiles becomes your primary study resource — organized the way exams actually test the material.
2. Write the distinguishing criteria between similar disorders as explicit comparison pairs. When the professor explains how to differentiate bipolar II from major depression, write it as a direct comparison: "Bipolar II vs. MDD: both have depressive episodes, but Bipolar II requires at least one hypomanic episode (elevated mood, decreased need for sleep, increased goal-directed activity for at least 4 days). Key question: has the patient ever had a period of abnormally elevated mood?" These comparison pairs are the highest-yield study material because exams present cases that could fit multiple diagnoses and ask you to choose correctly.
3. Capture the professor's diagnostic reasoning process during case studies verbatim. When the professor says "I would first rule out a medical condition because the symptoms started after a head injury, then consider adjustment disorder because there's a clear stressor within three months, and only diagnose MDD if the symptoms persist beyond what would be expected for the stressor," write that entire reasoning chain. The systematic approach to diagnosis — what to consider first, what to rule out, what criteria must be met — is the skill that exams test. Your professor's reasoning process is more valuable than any list of criteria because it teaches you how to use the criteria.
4. Use the professor's exact language for key distinctions — they use exam language. When the professor says "ego-dystonic," "psychomotor retardation," "anhedonia," or "flight of ideas," write these terms down with their definitions. Abnormal psychology exams use precise clinical vocabulary, and the professor uses that vocabulary during lectures to prepare you. Building a glossary of clinical terms with the professor's definitions and the context in which they were introduced gives you the language you need to answer exam questions correctly.
5. Record case discussions and use AI-generated quizzes to test diagnostic criteria differences. Case study discussions are where the professor reveals the critical diagnostic distinctions that separate similar disorders. Recording with Notella captures the full reasoning chain for every case, including the moments where the professor explains why one diagnosis is correct and another is not. Use Notella's quiz generator to create practice cases that test your ability to apply diagnostic criteria: "A patient reports intrusive thoughts about contamination that they recognize as irrational, and spends 2 hours daily washing hands. What is the most likely diagnosis?"

Abnormal psychology exams are diagnostic exercises — they give you a case and ask you to apply the criteria. The professor's case discussions are the best practice for these exams, but they happen in real time during class where you cannot simultaneously process the case, follow the reasoning, and take notes. AI recording removes this constraint entirely.

With Notella, you can search "differential diagnosis" across all your lectures and find every case where the professor walked through the reasoning process. You see how they approached each case, which criteria they checked first, and how they ruled out similar disorders. Reviewing these cases repeatedly builds the diagnostic reasoning skill that the exam actually tests — not memorized criteria lists, but the ability to apply criteria to novel cases.

The search function is also invaluable for studying specific disorders. Search "borderline personality disorder" and find every mention across the semester — the diagnostic criteria lecture, the case study discussion, the treatment comparison, and the professor's response to student questions. This comprehensive view of one disorder, assembled in seconds, gives you far deeper understanding than reading a single textbook chapter.

Abnormal psychology rewards students who build a systematic disorder reference throughout the semester. Here is the workflow:

Before lecture: Read the DSM criteria for the disorders to be covered. Knowing the criteria before class lets you focus on the professor's differential diagnosis reasoning and clinical examples rather than trying to memorize criteria during the lecture.

During lecture: Record with Notella. Fill in your disorder profile template for each new condition. Write comparison pairs for similar disorders. Capture the professor's diagnostic reasoning during case discussions. Note clinical vocabulary with definitions.

After lecture: Review the Notella transcript to complete disorder profiles and comparison pairs. Generate quiz questions in case vignette format to practice diagnostic reasoning. Build a running differential diagnosis guide that maps confusable disorder pairs to their key distinguishing criteria. Use spaced repetition to maintain the growing body of diagnostic knowledge throughout the semester.

This workflow builds the diagnostic reasoning skill that abnormal psychology exams actually test — the ability to read a case, consider the possibilities, and choose the correct diagnosis based on specific criteria.
