Summary
Post-stroke delirium is linked to increased mortality and functional disability. Patients experiencing delirium face a higher risk of death and greater impairment in the first year following a stroke.
Area of Science:
- Neurology
- Geriatrics
- Critical Care Medicine
Background:
- Limited research exists on the long-term outcomes of post-stroke delirium.
- Understanding the impact of delirium on mortality and functional disability is crucial for stroke patient care.
Purpose of the Study:
- To investigate the association between post-stroke delirium and mortality.
- To assess the degree of functional disability in patients with and without post-stroke delirium.
Main Methods:
- Neuropsychological assessments were conducted within the first week of stroke, at discharge, and at 3, 6, and 12 months post-stroke.
- Diagnostic tools included the Glasgow Coma Scale, Delirium Rating Scale, National Institutes of Health Stroke Scale, and Mini-Mental State examination.
Main Results:
- Delirious patients exhibited significantly higher mortality rates (p = 0.0005).
- Higher mortality was observed in patients with ischemic stroke (p = 0.0005).
- Delirious patients demonstrated greater functional impairment at discharge and up to one year post-stroke (p = 0.01).
Conclusions:
- Post-stroke delirium is associated with significantly increased mortality.
- Patients with delirium experience lower cumulative survival rates in the first year post-stroke.
- Delirium leads to a greater degree of functional disability following a stroke.

01:29Intellectual Disability
749
Intellectual disability (ID) is a neurodevelopmental condition characterized by deficits in intellectual and adaptive functioning that manifest during the developmental period. This condition encompasses challenges in reasoning, memory, problem-solving, and learning, accompanied by impairments in everyday life skills, such as communication, self-care, and social interactions. Intellectual disability affects approximately 1% of the population in the United States, impacting an estimated 5...

01:25Learning Disabilities
626
Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.

02:45Functional Groups
89.0K
Functional groups are a group of atoms with characteristic properties, which when linked to the carbon skeleton of a molecule, alter the properties of that molecule. For example, the presence of certain functional groups on a molecule will make them hydrophilic, whereas others will make them hydrophobic. These functional groups are an indispensable part of organic chemistry and important components of biological molecules, such as carbohydrates, proteins, lipids, and nucleic acids. Each...

01:11Functionalism
2.6K
William James, John Dewey, and Charles Sanders Peirce were instrumental in founding functional psychology, which draws heavily from Darwin's theory of evolution by natural selection. This theory suggests that individual traits, including behaviors, are adapted to their environments through natural selection. At the heart of functionalism is the concept of adaptation, meaning that a trait enhances an individual's chances of survival and reproduction.

01:58Mechanical Protein Functions
5.6K
Proteins perform many mechanical functions in a cell. These proteins can be classified into two general categories- proteins that generate mechanical forces and proteins that are subjected to mechanical forces. Proteins providing mechanical support to the structure of the cell, such as keratin, are subjected to mechanical force, whereas proteins involved in cell movement and transport of molecules across cell membranes, such as an ion pump, are examples of generating mechanical force.
