I now have the complete list of types of delusions from KS Narayan Reddy. Let me compile them and create a mnemonic.
From the textbook (p. 459), the 8 types are:
- Grandeur (exaltation)
- Persecution (paranoid)
- Reference
- Influence
- Infidelity
- Self-reproach (self-accusation)
- Nihilistic
- Hypochondriacal
Now let me create a mnemonic using the first letters: G, P, R, I, I, S, N, H
Here is the content from KS Narayan Reddy's Essentials of Forensic Medicine and Toxicology (p. 459) and a mnemonic built from it:
Types of Delusion (KS Narayan Reddy, p. 459)
- Grandeur (exaltation) - believes he is very rich/powerful
- Persecution (paranoid) - believes others are trying to harm/poison him
- Reference - believes strangers/media are talking about him specifically
- Influence - believes thoughts/actions are controlled by outside forces
- Infidelity - believes spouse is unfaithful (Othello syndrome)
- Self-reproach (self-accusation) - blames himself for past failures
- Nihilistic - believes he does not exist or the world does not exist
- Hypochondriacal - believes something is wrong with his body despite being healthy
Mnemonic: "Great Patients Rarely Imagine Ills; Sometimes Nothing Helps"
| Letter | Type |
|---|
| Great | Grandeur |
| Patients | Persecution |
| Rarely | Reference |
| Imagine | Influence |
| Ills | Infidelity |
| Sometimes | Self-reproach |
| Nothing | Nihilistic |
| Helps | Hypochondriacal |
Alternative shorter mnemonic using first letters G-P-R-I-I-S-N-H:
"Go Protect Royals - In India, Some Noble Heroes"
Both work well for recall. The sentence "Great Patients Rarely Imagine Ills; Sometimes Nothing Helps" is perhaps easier to remember because it paints a clinical picture - a patient who rarely admits to delusions and resists treatment.
