The Young Mania Rating Scale (YMRS) is an 11-item clinician-rated scale. A score of 20–25 indicates:

• A Hypomania
• B Moderate mania ✓
• C Severe mania requiring hospitalisation
• D Mixed episode

Explanation

YMRS scoring thresholds are: 0–12 = no mania / remission; 13–19 = mild mania / hypomania; 20–25 = moderate mania; 26–38 = severe mania; >38 = very severe mania. A YMRS of 20–25 signifies moderate mania, typically requiring pharmacological intervention but not necessarily immediate hospitalisation unless safety risks are present. The YMRS is widely used in clinical trials and outpatient monitoring of bipolar disorder. It assesses elevated mood, increased motor activity, sexual interest, sleep, irritability, speech rate, language/thought disorder, thought content, disruptive/aggressive behaviour, appearance, and insight.
