Advocating for a more accurate dementia diagnosis

Key points

  • Mixed dementia (more than one type) is common, but many doctors stop after one diagnosis. You must advocate for a thorough evaluation.
  • Track specific symptoms daily in a journal—this is your most powerful tool to show the doctor patterns that don’t fit a single type.
  • Don’t accept a vague 'dementia' label without asking for specifics. Request a referral to a specialist or memory clinic.
  • Rule out reversible causes first: depression, vitamin deficiencies, medication side effects, and sleep apnea can mimic dementia.
  • Use free resources like the 'Understanding Different Types of Dementia' PDF and the Alzheimer’s Association CareFinder tool to guide your advocacy.
  • You are the expert on your loved one’s daily life. Trust your observations and speak up—even if the doctor seems dismissive.

General caregiving information, not medical advice. Check medications and major care changes with your clinician.

Step-by-step

  1. Keep a daily symptom journal recording the date, time, and context of each episode, including memory, behavior, movement, and sleep. A concrete entry like 'March 5, 10 AM: Mom couldn't find the bathroom in her own home, but walked steadily' provides actionable evidence.

  2. Ask the doctor to provide a written diagnosis specifying the type of dementia and the supporting evidence. If given only 'dementia' or 'MCI', press: 'What type are we treating, and what makes you think so?'

  3. Before accepting a progressive diagnosis, request tests to rule out reversible mimics: depression, B12 deficiency, thyroid issues, sleep apnea, and medication side effects.

  4. If symptoms mismatch the diagnosis (e.g., visual hallucinations or movement trouble under an Alzheimer's label), request referral to a neurologist, geriatric psychiatrist, or memory clinic, and seek a second opinion if needed.

  5. Before each visit, write down your top three concerns. Request a longer appointment if possible, bring a note-taker, and ask for a written summary of decisions and next steps.

What not to do

  • Don't accept 'just dementia' or 'just aging' as a diagnosis — push for the specific type and stay open to revision as symptoms evolve.

  • Don't rely on online staging charts; they rarely account for mixed dementia. Track actual symptoms and changes over time instead.

  • Don't ignore sudden changes in confusion, walking, or alertness — these may signal stroke, infection, or medication issues, not progression.

  • Don't attend appointments alone; bring someone to take notes and advocate when emotions run high.

  • Don't assume the doctor will connect every dot — your daily observations are critical. Speak up about patterns you've noticed.

Practical tools

  • Symptom Tracking Journal

    A notebook or app like CareClinic. Each day record date, time, symptom, antecedent, and what helped. Example: 'March 5, 10 AM: Mom couldn't find the bathroom, confused and agitated. I guided her calmly; she settled in 10 minutes.' Bring to every appointment.

  • 'Understanding Different Types of Dementia' PDF

    Free from answersaboutalz.org. Lists symptoms, life expectancies, and treatments for Alzheimer's, vascular, Lewy body, frontotemporal, and mixed dementia. Use it to ask: 'My loved one has symptoms from this and that type — could it be mixed?'

  • Clinical Trial Finder at alzheimers.gov

    Search for dementia trials in your area. Participation often includes advanced brain imaging, neuropsychological testing, and access to new treatments at no cost.

Discuss with your clinician

Ask your doctor: 'Could my loved one’s symptoms be caused by a reversible condition like a vitamin deficiency, thyroid problem, or medication side effect? Should we run blood tests to rule these out?'

Ask: 'If we suspect mixed dementia, what specific tests (like brain MRI, PET scan, or spinal tap) would help clarify the diagnosis? Are there risks or benefits to each?'

Ask: 'Are there any medications that could help with symptoms of mixed dementia? For example, are cholinesterase inhibitors appropriate even if vascular dementia is present?'

Ask: 'If my loved one has hallucinations or agitation, what treatments are safest given the possibility of Lewy body dementia? Are there medications we should avoid?'

Ask: 'Can you refer us to a memory clinic or a geriatric psychiatrist for a second opinion? If not, can you recommend someone who specializes in complex dementia cases?'
