Delirium: When Confusion Calls for a CT

Understanding Delirium in Older Adults

Understanding Delirium

Delirium is a common and serious condition characterized by sudden confusion and cognitive impairment in older adults. It affects up to 50% of hospitalized elderly patients, often leading to prolonged hospital stays and increased mortality. The risk factors for delirium include advanced age, pre-existing cognitive impairment, and [acute medical illnesses](https://www.eper.A significant portion of older adults with delirium in the emergency department exhibit abnormal head CT findings, regardless of traditional risk factors. For example, an elderly patient with a urinary tract infection and pre-existing dementia may suddenly become disoriented and confused, highlighting how acute medical issues can exacerbate cognitive decline.

Importance of Accurate Diagnosis

Misdiagnosis or delayed diagnosis of delirium can worsen outcomes, highlighting the need for precise diagnostic tools. Imaging techniques, such as head CT scans, play a critical role in identifying underlying causes of delirium, like intracranial pathologies, which might otherwise be overlooked. For instance, a timely CT scan can reveal a subdural hematoma in a patient who fell recently, allowing for immediate surgical intervention. Early recognition of delirium symptoms can facilitate quicker intervention and better recovery outcomes, emphasizing the importance of accurate diagnosis.

Role of Head CT in Delirium Diagnosis

Identifying Potential Causes

Head CT scans are instrumental in detecting structural abnormalities such as hemorrhages, ischemic strokes, or tumors, found in 15.6% of elderly patients with altered mental status. Focal neurological deficits are a strong predictor of abnormal CT findings, with an odds ratio of 110.2. For instance, an elderly patient presenting with weakness on one side of the body and confusion might have an ischemic stroke detectable on a CT scan. Additionally, CT scans can reveal signs of cerebral atrophy, which may contribute to cognitive decline and delirium.

Guidelines for Use

Head CT is recommended for older adults experiencing new or worsening seizures, with a history of brain hardware, or presenting focal neurological deficits. Even in the absence of traditional risk factors, such as anticoagulant use, a head CT may still be necessary to rule out significant intracranial changes. Clinical guidelines suggest prioritizing head CT scans for elderly patients presenting with acute confusion or altered mental status, ensuring timely and appropriate intervention.

Benefits of Timely Imaging

Impact on Treatment

Timely head CT imaging leads to significant changes in medical strategies in 76.3% of cases with positive findings, such as additional neuro exams and treatment adjustments. For example, identifying a small bleed early can prompt closer monitoring and adjustments in anticoagulation therapy, preventing further complications. Early identification of the underlying cause through CT can direct appropriate and timely medical interventions, improving patient outcomes.

Reducing Unnecessary Procedures

Utilizing specific clinical indicators, such as a Glasgow Coma Scale score below 13, helps improve diagnostic yield and reduces unnecessary radiation exposure. A focused approach ensures that head CTs are reserved for patients with a higher likelihood of benefit, optimizing resource use and patient safety. The decision to perform a head CT should also consider patient history and presenting symptoms to maximize diagnostic effectiveness.

Common Causes of Delirium Detected by Head CT

Structural Abnormalities

Hemorrhages and ischemic strokes are common findings in head CTs of elderly patients with delirium. Approximately 6.4% of head CTs yield positive findings in this demographic, indicating structural causes. Other findings may include subdural hematomas, which are more prevalent in older populations due to increased fragility of blood vessels. For instance, an elderly patient who has suffered a minor fall may develop a slow-bleeding subdural hematoma detectable on a CT scan.

Other Contributing Factors

Sepsis and metabolic disturbances often present in patients with negative CTs, necessitating alternative diagnostic approaches. Inflammatory processes, such as infections, can also contribute to delirium and may not always be visible on imaging. Cognitive impairments due to medications or substance use should be evaluated in conjunction with CT findings for a comprehensive approach, as seen in cases where polypharmacy leads to confusion.
