An 88-year-old nonverbal female with advanced Alzheimer dementia presenting with 6 hours of progressive agitation, mild abdominal distension, and hemodynamic lability. Abdomen is deceptively soft on palpation; only imaging reveals massive pneumoperitoneum from a silent perforated peptic ulcer.

High-Yield Clinical Pearls
In nonverbal geriatric patients, vital sign lability and behavioral changes are the ONLY instability signals—a 'soft' abdomen does NOT exclude intra-abdominal catastrophe.
Atypical acute abdomen in the elderly is the rule, not the exception: thinned abdominal wall musculature, blunted peritoneal response, polypharmacy, and dementia mask classic peritonitis.
Avoid diagnostic overshadowing: new agitation in dementia is pain until proven otherwise; do not empirically sedate without ruling out surgical/medical emergency.
Upright chest x-ray demonstrating free air under the diaphragm is diagnostic of perforation; CT rarely changes management and should not delay surgical consultation in unstable patients.
Antibiotics within 1 hour, source control ASAP, and gentle resuscitation are the pillars of perforated viscus with septic physiology.
Advanced dementia + DNR ≠ DNI ≠ withdrawal of care. Engage the legally authorized representative for substituted judgment BEFORE non-emergent withdrawal.
Postoperative delirium is NOT irreversible decline; treat with non-pharmacologic bundles (sleep hygiene, reorientation, mobilization, sensory aids, family presence) before antipsychotics.
ICU disposition is determined by physiology, not age. Ageist rationing in acute surgical emergencies is a documented source of inequitable care.
