Breakthrough: Brain Sugar Metabolism Linked to Alzheimer’s Progression

An important study of the Buck Institute for Research on Aging, which has been published in Nature Metabolism (June 2025), it indicates how to promote the storage of sugar in brain cells, which can promote the treatment of Alzheimer's disease (AD) New prospects opens. This search challenges long-term beliefs about brain metabolism and provides the hope of innovative treatments.

Brain scan reveals Alzheimer's tau protein tangles.

Key Findings

• Neurons Store Sugar: Unlike previous perceptions, neurons store glycogen (a form of glucose). In Alzheimer's, excessive glycogen gets accumulated, which consist of Tau Protein, makes harmful confusion.
• Metabolic Dysfunction: This construction disrupts the Pentose Phosphate route (PPP), reduces antioxidant that protects neurons from oxidative stress, which increases Eddie progress.
• Therapeutic Potential: Promoting glycogen phosphorylase (GlyP), an enzyme which breaks glycogen, reduces Tau damage in fruit fly model and increases the lifetime up to 70%. It also improved human neuron health.

Why It Matters

This search redefines Alzheimer's only protein misfolding disease but also as metabolic disorder. It tells that why the GLP-1 drugs used for diabetes and weight loss are effective against dementia. For example, a test of 2024 was found that liraglutide slowed a cognitive decline in light Eddie patients up to 18%. Testing with semaglutide till September 2025 can confirm and confirm these benefits.

New Treatment Avenues

• Dietary Interventions: Fast or calorie restrictions naturally enhances GlyP activity, which copies protective effects seen in the laboratory model.
• Drug Development: GLP-1 receptor agonist can reduce the neuronal damage by targeting glycogen metabolism, antioxidant production.

Looking Ahead

This search highlight the relationship between brain sugars metabolism and neurodegeneration,, which provides a new approach to the treatment of Alzheimer's. As research moves forward, medical treatment can be supplemented by the current methods that target metabolic routes, which can change potentially in taking care of millions of people affected by Alzheimer.
