Alzheimer’s Disease Treatment
Alzheimer’s disease (AD) is a progressive neurodegenerative disorder that affects memory, cognition, and behavior. It is the most common cause of dementia, accounting for 60-80% of cases. As the global population ages, the prevalence of Alzheimer’s is rising, making effective treatment crucial. While there is no cure for Alzheimer’s, several treatments can slow progression, manage symptoms, and improve quality of life. This article explores the latest Alzheimer’s disease treatment options, their effectiveness, risks, costs, and availability in countries like India, China, the USA, and more.
What is the treatment for Alzheimer’s disease?
Alzheimer’s disease treatment involves a combination of pharmacological and non-pharmacological approaches. The primary goals are to:
- Slow cognitive decline
- Manage behavioral symptoms
- Improve daily functioning
- Support caregivers
Current FDA-approved medications include cholinesterase inhibitors (donepezil, rivastigmine, galantamine) and NMDA receptor antagonists (memantine). Emerging treatments, such as monoclonal antibodies (lecanemab, aducanumab), target amyloid plaques in the brain.
Indications
Treatment is recommended for individuals diagnosed with mild to moderate Alzheimer’s disease. Key indications include:
- Memory loss affecting daily activities
- Confusion and disorientation
- Mood and behavioral changes (depression, aggression, anxiety)
- Difficulty with language and problem-solving
Early intervention is crucial for better outcomes.
Procedure Details
Pharmacological Treatments
- Cholinesterase Inhibitors – Increase acetylcholine levels to improve communication between nerve cells.
- Donepezil (Aricept): Used for all stages.
- Rivastigmine (Exelon): Available as oral capsules or patches.
- Galantamine (Razadyne): Helps with memory and thinking.
- Memantine (Namenda) – Regulates glutamate to slow symptom progression in moderate to severe cases.
- Monoclonal Antibodies (Aducanumab, Lecanemab) – Target amyloid-beta plaques (FDA-approved but controversial due to limited efficacy and side effects).
Non-Pharmacological Approaches
- Cognitive stimulation therapy
- Physical exercise and diet modifications (Mediterranean diet)
- Occupational therapy for daily living skills
- Behavioral interventions for mood management
Effectiveness
- Cholinesterase Inhibitors: Show modest improvement in cognition and function for 6-12 months.
- Memantine: Helps delay symptom worsening in later stages.
- Lecanemab: Reduces amyloid plaques but has limited impact on cognitive decline.
- Lifestyle Interventions: Exercise and diet may slow progression.
No treatment reverses Alzheimer’s, but early intervention can improve quality of life.
Risks and Side Effects
- Cholinesterase Inhibitors: Nausea, vomiting, diarrhea, insomnia.
- Memantine: Dizziness, headache, confusion.
- Aducanumab/Lecanemab: Brain swelling (ARIA), microbleeds, high cost.
Patients should be monitored for adverse effects.
Recovery and Aftercare
Since Alzheimer’s is progressive, long-term care is essential:
- Regular follow-ups with neurologists
- Caregiver support programs
- Safety modifications at home
- Mental health counseling for patients and families
Cost and Availability
Alzheimer’s treatment costs vary by country and healthcare system.

Treatment Options in India and China
- India: Generic versions of donepezil and memantine are affordable. Advanced treatments like lecanemab are unavailable.
- China: Government subsidies reduce drug costs. Lecanemab is under clinical trials. Traditional medicine (e.g., Ginkgo biloba) is also used.
Patient Experiences
Many patients report temporary improvement in memory and mood with medication. Caregivers emphasize the importance of support groups and therapy. Some express frustration over the high cost of newer treatments like lecanemab.
FAQ
1. Can Alzheimer’s be cured?
No, but treatments can slow progression.
2. What is the best treatment for early-stage Alzheimer’s?
Cholinesterase inhibitors like donepezil are commonly prescribed.
3. Are new drugs like lecanemab effective?
They reduce amyloid plaques but show limited cognitive benefits.
4. How much does Alzheimer’s treatment cost in India?
Generic drugs cost 20−80/month; advanced therapies are unavailable.
5. Is stem cell therapy effective for Alzheimer’s?
Still experimental with no proven benefits.
Alzheimer’s disease is treated by symptom management and quality of life improvement. Although commonly used drugs such as donepezil and memantine are being used, new drugs such as lecanemab provide hope but at great expense and risk. India and China offer low-cost generic drugs, whereas the USA is the leader in new treatments. Early diagnosis and a multidisciplinary team approach are still the pillars of Alzheimer’s care.
