What this trial studies

This observational study aims to investigate the factors influencing drug response to acetylcholinesterase inhibitors and NMDA receptor antagonists in patients diagnosed with Alzheimer's Disease. Participants will be categorized based on their prescribed medications at baseline, and their treatment responses will be monitored over a period of six months. The study will include newly diagnosed patients who are treatment naive or have not taken specific medications in the last three months. The goal is to better understand how different therapies affect patient outcomes.

Who should consider this trial

Good fit: Ideal candidates are newly diagnosed Alzheimer's patients aged 65 and older who are treatment naive or have not taken specific medications recently.

Not a fit: Patients with dementia caused by structural or vascular issues other than Alzheimer's Disease may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment strategies for Alzheimer's patients, enhancing their quality of life.

How similar studies have performed: While similar studies have explored drug responses in Alzheimer's, this specific approach focusing on multiOMICs and treatment-naive patients is relatively novel.
