Symptom 8: Rapid Onset
Unlike many cognitive disorders that develop gradually over time, delirium’s hallmark is its rapid onset. One might be entirely coherent and oriented one day, and then display multiple symptoms of delirium the next. This swift transition can be deeply unsettling for both the individual and their loved ones.
Often, it’s the caregivers or family members who first notice this abrupt shift. A previously punctual person might forget crucial appointments, or someone who’s been calm their whole life might suddenly exhibit extreme agitation. Given the rapid progression, these changes are hard to miss.
The speed at which delirium sets in often hints at an acute underlying cause. This could be a new medication, a recent surgery, or even an untreated infection. The sudden nature of the onset is a clarion call for prompt medical evaluation to pinpoint and address the root cause.
Given the rapidity of symptom emergence, timely medical attention is crucial. The quicker the underlying cause is identified and treated, the better the chances of a full recovery. Families and caregivers should act promptly, seeking professional guidance without delay. (8)
