Summary
Diffusion tensor imaging (DTI) shows promise for assessing white matter integrity in Alzheimer disease (AD) and mild cognitive impairment (MCI). This neuroimaging tool aids in diagnosing cognitive disorders and understanding pathological processes.
Area of Science:
- Neuroimaging
- Neurology
- Biomedical Engineering
Background:
- Alzheimer disease (AD) and mild cognitive impairment (MCI) involve white matter abnormalities.
- Diffusion tensor imaging (DTI) is increasingly recognized for evaluating white matter integrity.
Purpose of the Study:
- To review DTI principles, processing, and analysis frameworks.
- To present findings from studies using DTI in AD and MCI.
- To discuss the role of DTI in understanding white matter degeneration patterns.
Main Methods:
- Review of existing literature on DTI applications in AD and MCI.
- Discussion of DTI principles and analysis methodologies.
- Synthesis of results from various DTI studies.
Main Results:
- DTI can detect microstructural white matter changes associated with AD and MCI.
- Abnormalities may stem from primary alterations or secondary degeneration of white matter tracts.
- Assessing whole-brain diffusion versus specific regions is an ongoing research question.
Conclusions:
- DTI is a promising neuroimaging tool for differential diagnosis of cognitive disorders.
- DTI can help elucidate the pathological processes underlying AD and MCI.
- Further research is needed to optimize DTI application in clinical settings.

01:22Dementia l: Introduction
Dementia is an acquired, progressive syndrome characterized by a decline in multiple cognitive domains severe enough to impair daily functioning and reduce independence. Although memory loss is a central feature, the diagnosis requires additional deficits involving language, executive function, visuospatial skills, judgment, calculation, or abstract reasoning. These cognitive impairments reflect underlying neurodegenerative or vascular processes that gradually disrupt neuronal networks...

Understanding and evaluating diffusion and perfusion is critical in assessing a patient's respiratory and circulatory health. These processes play key roles in maintaining the body's internal environment, ensuring that tissues receive adequate oxygen while waste products are efficiently removed.

01:23Alzheimer Disease ll: Pathophysiology
Alzheimer disease involves structural changes in the brain that begin long before symptoms appear. The most distinctive features are extracellular neuritic plaques and intracellular neurofibrillary tangles.Neuritic plaques form in the cerebral cortex and around blood vessels. These plaques contain a dense core of beta-amyloid (Aβ)—a toxic protein fragment that clumps outside neurons. The core is surrounded by damaged neuronal extensions, as well as reactive astrocytes and microglia. Abnormal...
01:29Alzheimer Disease l: Introduction
Alzheimer disease is a chronic, progressive, and irreversible neurodegenerative disorder and the most common cause of dementia in older adults. It leads to gradual neuronal loss, causing cognitive decline, behavioral changes, and loss of functional independence.Risk Factors and EtiologyThe disease is multifactorial. Age is the strongest risk factor, with prevalence doubling every 5 years after age 65. Genetic factors include mutations in genes such as APP, PSEN1, and PSEN2, which are associated...
01:26Alzheimer's Disease: Overview
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ and tau...
