Based on demographic data, the knowledge level of nurses is influenced by three thinks, namely: education (p-value = 0.01), exposure to information about dementia (p-value = 0.02); and experience in handling dementia cases (p-value = 0.01).

Therefore, training and providing information about dementia are still needed to improve the skills of nurses in the field.
