Table 2: Diagnostic Criteria of Paraneoplastic Neurologic Disorders.
| Diagnostic Criteria of Paraneoplastic Neurologic Disorders | |
| Definite PND | |
| Classic syndrome with cancer diagnosed within 5 years of neurological symptom | |
| Non-classic syndrome that resolves or significantly improves after cancer treatment without concomitant immunotherapy, provided that the syndrome is not susceptible to spontaneous remission | |
| Non-classic syndrome with cancer diagnosed within 5 years of nuerological symptoms development and positive neuronal antibodies | |
| Neurological syndrome (classic or not) without cancer and with well characterized antineuronal antibodies (Hu, Yo, Ma, CV2, Ampiphysin and Ri) | |
| Possible PND | |
| Classic syndrome with high risk of cancer without antineuronal antibodies | |
| Neurological syndrome (classic or not) without cancer and with partly characterized antineuronal antibodies | |
| Non-classic syndrome with cancer within 2 years of neurological symptom development without neuronal antibodies | |
