Treatment recommendations by dementia subtype and stage
Key points
- Treatment is tailored to the dementia subtype and stage; what works for Alzheimer's may not work for frontotemporal or Lewy body dementia.
- Non-drug approaches (environmental changes, routine, communication strategies) are always the first line for behavioural symptoms.
- Acetylcholinesterase inhibitors are only recommended for Alzheimer's disease, dementia with Lewy bodies, and Parkinson's disease dementia, not for frontotemporal dementia.
- For vascular dementia, managing cardiovascular risk factors (blood pressure, diabetes, cholesterol) is the primary treatment.
- Mixed dementia (most common) requires a combined treatment plan addressing all underlying types.
- In late-stage dementia, the focus shifts to comfort, pain management, and preventing complications; discuss palliative care and hospice with the doctor.
General caregiving information, not medical advice. Check medications and major care changes with your clinician.
Step-by-step
Step 1: Get an accurate subtype diagnosis from a specialist. Ask your GP for a referral to a memory clinic, neurologist, or geriatrician. The specialist will use specific criteria (like NINDS-AIREN for vascular dementia or international consensus criteria for Lewy body dementia) and may order brain scans (MRI or CT) to help confirm the subtype. This is crucial because treatment recommendations differ by type.
Step 2: For Alzheimer's disease in early to moderate stages, discuss with the doctor whether acetylcholinesterase inhibitors (donepezil, rivastigmine, galantamine) are appropriate. These can temporarily improve memory and thinking for some people. They are not a cure, but they may help maintain function for a while. For moderate to severe Alzheimer's, a medication called memantine (an NMDA receptor antagonist) may be added. Note: these medications are not recommended for frontotemporal dementia or mild cognitive impairment.
Step 3: For vascular dementia, the primary treatment is managing cardiovascular risk factors. Work with the GP to control high blood pressure, diabetes, high cholesterol, and to encourage a healthy diet, exercise, and stopping smoking. Antiplatelet drugs (like aspirin) or anticoagulants may be prescribed to reduce the risk of further strokes, but only after a doctor's assessment. There are no specific dementia medications approved for vascular dementia, but sometimes doctors prescribe the same drugs used for Alzheimer's if there is also Alzheimer's pathology (mixed dementia).
Step 4: For dementia with Lewy bodies (DLB), be aware that antipsychotic drugs can cause severe reactions. Always discuss any use of antipsychotics with the doctor and never make medication changes without medical advice. Prioritise non-drug strategies (see tools below) and ask the doctor about the safest plan. Acetylcholinesterase inhibitors (like rivastigmine) are often used and can help with cognitive symptoms and hallucinations. For Parkinson's disease dementia (which is similar), the same approach applies. Always tell the doctor about any new symptoms like stiffness, falls, or sleep problems.
Step 5: For frontotemporal dementia (FTD), medications are limited. Antidepressants (like SSRIs) may help with behavioural symptoms such as apathy, disinhibition, or compulsive behaviours. There are no medications approved for the cognitive symptoms of FTD. Non-drug approaches are key: create a structured routine, reduce stimulation, and use simple, direct communication. Acetylcholinesterase inhibitors can worsen FTD symptoms and are not recommended. If such a medication has been prescribed, speak with the doctor before making any changes. Never discontinue a medication without a clinician's guidance.
Step 6: In middle to late stages, focus on managing behavioural and psychological symptoms (agitation, aggression, depression, anxiety). Always start with non-drug approaches: check for pain, hunger, thirst, or discomfort; maintain a calm environment; use music, gentle touch, or familiar activities. If these are not enough, the doctor may consider low-dose medications like antidepressants or, very cautiously, antipsychotics (but only after discussing risks, especially for DLB). The goal is to improve quality of life, not to sedate.
Step 7: In late-stage dementia (stage 6 or 7 on the FAST scale), the priority shifts to comfort care. This includes managing pain (use the Pain Assessment in Advanced Dementia scale), preventing pressure sores (regular turning, special mattresses), ensuring adequate hydration and nutrition (with assistance or feeding tubes only after careful discussion with the team), and treating infections promptly. Discuss with the GP about setting up a palliative care plan and considering hospice eligibility if the person meets criteria (e.g., significant weight loss, recurrent infections, functional decline).
Step 8: For mixed dementia (most common), the treatment plan must address all components. For example, if the person has Alzheimer's and vascular dementia, they may receive Alzheimer's medications plus aggressive management of blood pressure and cholesterol. Regular monitoring by a specialist is essential because the combination of symptoms can change over time. The person may also need input from multiple professionals: neurologist, geriatrician, occupational therapist, and speech therapist.
Step 9: Engage non-pharmacological therapies at every stage. Occupational therapy can help with daily tasks and home safety. Speech and language therapy can assist with communication difficulties and swallowing problems (especially in later stages). Cognitive rehabilitation (for early stages) can help maintain skills. These therapies are available through the NHS, but waiting lists can be long, so ask for a referral as early as possible.
Step 10: Build a support team and educate yourself. Join a caregiver support group (online or local), access resources from the Alzheimer's Society (UK), and use tools like the 'Understanding Different Types of Dementia' PDF from answersaboutalz.org. Caregiver education is a vital part of treatment because it helps you manage stress, understand what to expect, and communicate effectively with healthcare professionals.
What not to do
Do NOT assume all dementias are Alzheimer's and use Alzheimer's medications for other types. This can be ineffective or harmful. For example, acetylcholinesterase inhibitors are not recommended for frontotemporal dementia and may worsen symptoms. Always confirm the subtype before starting any dementia medication.
Do NOT use antipsychotic medications as a first-line treatment for agitation or hallucinations, especially in Lewy body dementia. These drugs can cause severe side effects, including parkinsonism (stiffness, tremors), sedation, and increased risk of stroke. Instead, try non-drug approaches first and only use medications after a specialist's careful assessment.
Do NOT stop or change medications without consulting the doctor. Some medications need to be tapered slowly to avoid withdrawal effects or a sudden worsening of symptoms. For example, stopping donepezil abruptly can cause a rapid decline in cognition. Always discuss any concerns with the clinical team.
Do NOT ignore other health conditions (like high blood pressure, diabetes, or infections) thinking they are 'just part of dementia.' These conditions can worsen dementia symptoms and need active treatment. For vascular dementia, controlling blood pressure is one of the most important things you can do to slow progression.
Do NOT assume that because there is no cure, there is nothing to do. Many treatments can improve quality of life, manage symptoms, and help the person stay independent longer. Non-drug approaches, caregiver support, and environmental modifications can make a huge difference.
Do NOT delay seeking specialist help. Early and accurate diagnosis allows for better treatment planning and access to appropriate medications and therapies. If your GP says 'it's just old age,' push for a referral to a memory clinic.
Practical tools
The 'Pain Assessment in Advanced Dementia (PAINAD)' Scale
For late-stage dementia, use this simple 5-item scale to detect pain when the person cannot speak. Observe: breathing (e.g., noisy, labored), vocalization (e.g., moaning, calling out), facial expression (e.g., frowning, grimacing), body language (e.g., tense, fidgeting), and consolability (can they be soothed?). Score each 0-2, total 0-10. A score of 4 or more suggests pain. Use the scale to detect possible pain, and then discuss the score with the doctor to determine whether paracetamol or another pain relief strategy is appropriate. Do not give medication without first consulting a healthcare professional.
The 'ABC' Approach for Behavioural Symptoms
When your loved one becomes agitated or aggressive, use the ABC method: Antecedent (what happened just before? e.g., a change in routine, a request to bathe), Behaviour (what exactly did they do? e.g., shouting, hitting), Consequence (what happened after? e.g., you gave in, you left the room). Write this down and share with the doctor or therapist. This helps identify triggers and find non-drug solutions, like adjusting the environment or changing how you communicate.
Medication Tracker and Side Effect Log
Create a simple chart listing all medications (name, dose, time, purpose). Each day, note any new symptoms (e.g., dizziness, confusion, falls, nausea, stiffness). Bring this to every doctor's appointment. This is especially important for Lewy body dementia, where side effects to antipsychotics can be severe, and for vascular dementia, where blood pressure medications may cause dizziness and falls.
The 'Redirection' Phrase Bank for Frontotemporal Dementia
For FTD, where disinhibition or repetitive behaviours are common, have a set of calm, simple phrases ready. Instead of saying 'Stop doing that,' say 'Let's go for a walk now' or 'I see you're looking for something. Let's find it together.' Use a neutral tone, avoid arguments, and redirect to a different activity. Practice these phrases so they come naturally in stressful moments.
Environmental Checklist for Lewy Body Dementia
Because people with DLB are sensitive to visual hallucinations and movement problems, adjust the home: reduce clutter, use nightlights to prevent falls, avoid patterned wallpaper or busy carpets (which can trigger hallucinations), and keep rooms well-lit but not glaring. Remove mirrors if they cause confusion (the person may think a stranger is in the room). This can reduce agitation without medication.
The 'Memory Aid Kit' for Early Alzheimer's
Create a small box or folder with: a large-print clock, a whiteboard for daily schedule (e.g., '9am breakfast, 10am walk'), a pill organizer with days of the week, a list of emergency contacts with photos, and a simple 'memory book' with family photos and names. Use these consistently to help the person feel oriented and in control. Review with an occupational therapist for personalised advice.
Discuss with your clinician
Ask the doctor: 'What specific type of dementia does my loved one have, and what diagnostic criteria were used to determine this?'
Ask: 'Are acetylcholinesterase inhibitors (like donepezil) or memantine appropriate for this subtype and stage? What are the potential benefits and side effects?'
Ask: 'For vascular dementia, what are the target blood pressure and cholesterol levels, and how often should they be checked?'
Ask: 'If my loved one has Lewy body dementia, what is the plan for managing hallucinations or agitation without using antipsychotics? Is it safe to consider any antipsychotic, and if so, under what conditions?'
Ask: 'For frontotemporal dementia, are there any medications (like antidepressants) that might help with specific behaviours? What non-drug strategies do you recommend?'
Ask: 'In late-stage dementia, when should we consider stopping medications like donepezil or memantine? What are the signs that comfort care should be the main focus?'
Ask: 'Can we get a referral to an occupational therapist, speech therapist, or palliative care team?'
Ask: 'What are the criteria for hospice eligibility in the UK, and how do we access this service?'
Ask: 'If my loved one is already on an antipsychotic or acetylcholinesterase inhibitor, what is the safest way to adjust or stop it? Should it be tapered?'
Ask: 'Before giving any new medication for pain or agitation, what should I discuss with you first?'
