“And interestingly enough, you know, when people have dementia and Alzheimer's, they usually die because of, they can't eat. So that's a bigger problem than, you know, the dementia itself.”

The claim, plainly

Patients with dementia and Alzheimer's disease usually die because of their inability to eat rather than from the dementia itself.

a quote alone can be ambiguous, so this restates it with the references and context of the conversation around it resolved. AI-written; the tape below the player is the source.

Assessment

Peer-reviewed medical literature and epidemiological mortality data confirm the claim's clinical substance. In advanced Alzheimer's disease and dementia, progressive neurological deterioration directly impairs swallowing and appetite (dysphagia and feeding difficulties). While dementia is classified on death certificates as the underlying cause of death, the overwhelming majority of immediate causes of death are directly driven by eating impairment: primarily aspiration pneumonia (accounting for approximately 40–45% of immediate deaths) and cachexia/dehydration/malnutrition (accounting for 35–53% of end-stage deaths).

A landmark prospective study in the New England Journal of Medicine (Mitchell et al., 2009) found that 85.8% of patients with advanced dementia developed eating problems, with high subsequent 6-month mortality.
A prospective study in the International Journal of Geriatric Psychiatry (van der Steen et al., 2007) identified cachexia and dehydration as the single most common immediate cause of death in dementia patients (35.2% overall, 53.2% in the final phase).
Autopsy and clinical cohort studies (e.g., Manabe et al., BMC Geriatrics, 2019; Kalia, Metabolism, 2003) establish that severe dysphagia leading to aspiration pneumonia is the leading immediate fatal complication in end-stage Alzheimer's disease.
