Intrinsic connectivity network patterns in dementias.
| Dementia subtype | Intrinsic connectivity pattern |
| Alzheimer | Default mode network shows reduced connectivity | FTD behavioral variant | Salience network shows reduced connectivity | Parkinson’s | BN-thalamocortical loops show increased connectivity | DLBD | Uncertain at present but may show ascending brainstem projection system | CBG | Uncertain |

FTD: frontotemporal lobe disorder, DLDB: diffuse lewy body disease, BN: basal nuclei (basal ganglia), CBG: corticobasal-ganglionic disorder. Adapted and modified from [35].
