What is Alzheimer's Disease?

Nov. 15, 2026

People with diabetes could be at a 53% higher risk of Alzheimer's disease, compared to those living without the metabolic disorder, a review of studies has found.

About Alzheimer's Disease:

  • It is a progressive neurodegenerative disorder characterized by memory loss, cognitive decline, and behavioural impairment.
    • Central to its pathology is the misfolding and aggregation of amyloid-β (Aβ), which self-assembles into fibrils and deposits as extracellular plaques that trigger neurotoxic cascades leading to synaptic dysfunction and neurodegeneration.
  • It is the most common cause of dementia, accounting for 60-80% of all dementia cases worldwide.
  • The disease disrupts communication between brain cells, leading to a decline in cognitive and functional abilities.
  • Cause: The exact cause of Alzheimer’s disease is not fully understood, but it is believed to be influenced by a combination of genetic, environmental, and lifestyle factors.
  • Treatment: There’s no cure for Alzheimer’s, but certain medications and therapies can help manage symptoms temporarily.
