Cognitive Functionality of Patients with Delirium after Stroke

Area of Science:

• Neurology
• Psychiatry
• Geriatrics

Background:

• Delirium is a common, acute condition affecting all age groups, frequently seen in intensive care units.
• It presents suddenly, requiring prompt recognition and management.
• Limited research exists on post-stroke delirium and its cognitive impact.

Purpose of the Study:

• To investigate the cognitive functionality of patients experiencing delirium in the acute phase of a stroke.
• To compare cognitive outcomes between stroke patients with and without delirium over time.

Main Methods:

• A prospective study involving 100 stroke patients with delirium and 100 controls without delirium.
• Cognitive function assessed using neurological, neuropsychiatric, and neuropsychological tests at five time points.
• Standardized assessments included the Glasgow Coma Scale, Delirium Assessment Scale, and Mini-Mental State Examination.

Main Results:

• Delirious patients showed significantly worse cognitive functioning at three, six months, and one year post-stroke compared to non-delirious patients.
• No significant differences in cognitive function were observed based on gender, age, stroke type, or location.
• Older patients (≥65 years) with delirium exhibited a statistically significant higher degree of cognitive dysfunction.

Conclusions:

• Delirium is a significant factor that markedly reduces cognitive functioning in post-stroke patients.
• Early identification and management of delirium are crucial for improving long-term cognitive outcomes in stroke survivors.
