How Alzheimer's Actually Kills — and Why It's Already Too Late at Diagnosis
At 27:20 · chapter starts 26:40
Bartlett asks a question most people don't think to ask: how does Alzheimer's actually kill you? Nicola's answer is visceral and clarifying [1] — Louisa Nicola "People don't die 'of Alzheimer's' — they die of what the disease causes. As the brain loses its signals, patients lose the ability to swall…" 27:00 . The disease progressively strips the brain of its fundamental control signals. Patients lose the ability to swallow. They lose coordination and fall. They asphyxiate. Death comes from these downstream failures, not from 'Alzheimer's disease' itself as a label. This reframe matters: it makes the progression feel real rather than abstract. Nicola then delivers the episode's starkest warning. Alzheimer's, she says, is like end-stage cancer: once you receive the diagnosis, there is no cure, no drug that reverses it, no second chance. The progression window — mild cognitive impairment — can last approximately 20 years, and within that window, progression can be slowed. But the moment a formal diagnosis lands, you are past the point of reversal. Dementia is not a distant abstraction: it is the number one cause of death for women in the UK, and the leading cause for both sexes in Australia. This chapter functions as the episode's emotional centrepiece — the reason everything discussed before it matters.
People don't die 'of Alzheimer's' — they die of what the disease causes. As the brain loses its signals, patients lose the ability to swallow, lose balance, and suffer asphyxiation. Alzheimer's is end-stage, irreversible once diagnosed, which is exactly why the 20-year prevention window matters so much.
Mild cognitive impairment, the precursor to Alzheimer's disease, progresses silently for approximately 20 years before a clinical Alzheimer's diagnosis is made.
