Understanding Delirium and Dementia

This video tutorial explains the differences between delirium and dementia using the mnemonic 'OCD Camps'. Delirium is characterized by a rapid onset, fluctuating course, and altered consciousness, while dementia has a gradual onset, progressive course, and clear consciousness. Attention is significantly impaired in delirium, whereas memory loss is more prominent in dementia. Psychomotor changes and sleep-wake cycle alterations are also discussed, highlighting the distinct features of each condition.
