- Alzheimer's DementiaCholinesterase InhibitorsDrugs like donepezil and rivastigmine slow cognitive decline in mild-to-moderate Alzheimer's by increasing acetylcholine

- DeliriumSuperimposed on DementiaPatients with dementia can develop acute delirium; any sudden worsening should be investigated as possible delirium
