What’s the Latest in Dementia Treatment: 2026

Every March we review what’s new in dementia treatment. 2025 brought several important changes, especially in how Alzheimer’s disease is diagnosed. Here’s what families should know as of March 2026.

The first FDA-cleared blood tests for Alzheimer’s

• In May 2025, the FDA cleared the first blood test to help diagnose Alzheimer’s disease, Fujirebio’s Lumipulse test, for adults 55 and older who have signs of memory decline. It measures proteins in the blood linked to amyloid plaques in the brain.
• In October 2025, the FDA cleared Roche’s Elecsys pTau181 blood test for use in primary care, to help doctors rule out Alzheimer’s-related amyloid in people with symptoms.

These tests don’t replace a full evaluation by a doctor, but they can make diagnosis faster, less invasive and less expensive than PET scans or spinal taps.

Easier ways to take treatment

In August 2025, the FDA approved Leqembi Iqlik, an under-the-skin (subcutaneous) autoinjector version of lecanemab for maintenance treatment. After the initial months of IV infusions, eligible patients can give themselves a weekly injection at home instead of traveling for infusions.

Safer dosing for Kisunla

In July 2025, the FDA updated the label for Kisunla (donanemab) with a slower starting dose schedule. In a clinical study, the gradual schedule lowered the rate of ARIA, the brain swelling side effect seen with this class of drugs.

Lifestyle matters

The U.S. POINTER study, presented in July 2025, found that older adults at risk for memory decline who followed a structured program of exercise, healthy eating, brain challenges, social activity and health monitoring had better cognitive results than those who followed a self-guided program. It’s encouraging evidence that healthy habits can help the brain.

A disappointment

In November 2025, two large trials of semaglutide (the drug in Ozempic and Wegovy) in early Alzheimer’s did not show that it slowed the disease. Research into other approaches continues.

What it means for families

The newest treatments still help only people in the early stages of Alzheimer’s, so early evaluation matters. For people living with moderate or advanced dementia, compassionate daily care, routine, activity and connection remain the heart of good treatment.
