Hospital delirium—an abrupt, fluctuating disturbance in attention and alertness—should not be mistaken automatically for dementia progression. Before discharge, families should ask about delirium testing, possible causes, medication changes, daily-care safety, and follow-up. Dementia usually develops slowly and progresses more consistently. Delirium can occur in someone who already has dementia, making a sudden hospital decline especially important to investigate.

Does the change fit delirium or dementia?
Ask the hospital team when the change began and whether symptoms varied during the day. Delirium typically starts over hours or days and fluctuates, while dementia generally changes over a longer period, according to NIH MedlinePlus guidance on delirium. Describe the person's baseline before hospitalization.
Be specific: Could they follow a conversation, recognize relatives, manage meals, or take medications correctly? Then identify what is new. Examples include unusual sleepiness, agitation, reduced awareness, or an inability to stay focused. A sharp departure from baseline deserves evaluation even when the person has diagnosed dementia.
Was delirium assessed and were causes investigated?
Ask whether clinicians performed and documented a delirium assessment. NICE recommends the 4AT when delirium indicators appear, with CAM-ICU or ICDSC used in critical care or post-anesthesia recovery.
Families can ask which possible triggers were evaluated and which remain unresolved: If clinicians cannot distinguish dementia progression from delirium superimposed on dementia, ask whether they are managing delirium first. Also request that the diagnosis and remaining concerns appear in both hospital and primary-care records.
- Infection
- Dehydration or electrolyte imbalance
- Medication effects or withdrawal
- Severe pain
- Sleep deprivation
What changed in the medication plan?
Ask for a review of every new, stopped, or adjusted medicine, especially sedatives, opioids, and other drugs that may affect thinking. Do not rely on an older home list or verbal instructions alone.
The Medicare discharge planning checklist calls for a reconciled medication list showing what the patient should continue, stop, or change after discharge. For each change, ask: Compare the final list with medicines already at home. Resolve duplicate names, conflicting instructions, and unclear stop dates before leaving.
- What is the medicine for?
- What dose and schedule should be followed?
- Which previous medicines should no longer be taken?
- Who should be contacted about side effects or worsening confusion?
Is the discharge setting safe today?
A person's usual living arrangement may no longer match their current abilities. Ask the team to address whether the patient can safely bathe, use the toilet, climb stairs, prepare food, take prescriptions, and attend appointments. For each task the patient cannot manage, identify who will help and when.
Ask whether the plan requires caregiver training, home health services, equipment, or a different care setting. Do not accept "family will assist" as the entire plan. Name the responsible person, confirm that they understand each task, and identify any periods when no help will be available.
What should happen after discharge?
Delirium is often temporary, but recovery can take weeks or months. Ask what improvement the team expects, when follow-up should occur, and who will reassess persistent or worsening symptoms. Unresolved delirium may require another search for underlying causes and possible dementia evaluation.
A useful handoff includes warning signs in plain language, pending test results, scheduled appointments, medication instructions, and a reliable contact path. These are among the discharge areas emphasized in AHRQ guidance for preventing problems at home. Before leaving, have the caregiver repeat the plan in their own words. Write down exactly whom to call, including after hours, if confusion worsens or the patient cannot safely complete essential daily tasks.
