Objective: There is no universally accepted consensus for organic psychiatric disorders (OPDs) between the two major classifications, ICD‐10 and DSM‐IV. The aim was to compare the coverage of these systems with the Lindqvist & Malmgren (LM) classification system for organic psychiatry. Method: Organic psychiatric disorders were diagnosed according to ICD‐10, DSM‐IV, and the LM system in 119 patients 12 months after surgery as a result of aneurysmal subarachnoid hemorrhage. Results: Among 35 patients with astheno‐emotional (AE) disorder (LM system), 83% (95% CI: 67–92%) had mild cognitive disorder (MCD) according to ICD‐10 clinical descriptions and diagnostic guidelines (CDDG), 49% (95% CI: 33‐64%) had MCD according to ICD‐10 diagnostic criteria for research (DCR), and 34% (95% CI: 21–51%) had mild neurocognitive disorder according to DSM‐IV. The coverage for other OPDs did not differ between the systems. Conclusion: The coverage for AE disorder (LM system) was significantly higher than the corresponding diagnoses of the ICD‐10 and DSM‐IV systems. Modifications of the latter systems are suggested.
