Patient's Query

Hello doctor,

I am a 50-year-old woman with Alzheimer's disease. I have heard about Lecanemab and would like information on the symptoms of Alzheimer's disease, Lecanemab's status with the FDA eligibility criteria for treatment, differences from other medications, potential side effects, and its effectiveness in trials. I am eager to explore options as I forget things, like misplacing keys. It affects me, and my family makes fun of it. Please help.

Thank you.


Welcome to icliniq.com.

I have read your query and understand your concern.

Alzheimer's disease (AD) is a neurodegenerative condition characterized by cognitive and behavioral decline, significantly impacting social and occupational functioning. It is an incurable illness with an extended preclinical phase and a progressively deteriorating course. Common signs and symptoms include:

  1. Memory loss.

  2. Confusion about familiar places.

  3. Increased time for routine tasks.

  4. Difficulty managing finances.

  5. Impaired judgment which leads to poor decision-making.

  6. Loss of spontaneity and initiative.

  7. Changes in mood and personality, often accompanied by heightened anxiety

Lecanemab, a monoclonal antibody and anti-amyloid medication, is employed for Alzheimer's disease treatment. It is indicated for individuals in the mild cognitive impairment or mild dementia stages. This FDA (Food and Drug Administration) approved medication is highly potent and effective, sharing no distinct criteria from other Alzheimer's medications. Clinical trials have demonstrated a 95 percent efficacy rate, with users experiencing good success rates. Adverse effects, if any, are generally mild, including headaches, cough, rash, and diarrhea.

I hope this helps.

Please revert in case of further queries.

Thank you.
