Summary
Alzheimer disease (AD) may stem from immune system dysfunction, specifically faulty regulation and autoimmunity. Research suggests activated CD8 T-lymphocytes play a key role in AD immunopathogenesis.
Area of Science:
- Neuroimmunology
- Immunopathology of neurodegenerative diseases
Background:
- Alzheimer disease (AD) pathophysiology may involve immune factors.
- Initial hypothesis proposed AD as a systemic immune-derived disease with brain-specific clinical manifestations.
- The role of immune dysregulation and autoimmunity in AD was previously considered.
Purpose of the Study:
- To investigate the role of immune factors in Alzheimer disease (AD) pathogenesis.
- To explore the hypothesis that AD is an immunologically derived systemic disease.
- To examine the potential involvement of T-lymphocyte activation in AD.
Main Methods:
- Analysis of immune factors implicated in Alzheimer disease.
- Investigation of T-lymphocyte phenotypes, specifically CD8.
- Assessment of immune regulation and autoimmunity in the context of AD.
Main Results:
- Evidence suggests immune factors are involved in Alzheimer disease (AD) pathophysiology.
- The activation of immunoregulatory T-lymphocytes with a CD8 phenotype is highlighted.
- Faulty immune regulation and autoimmunity are implicated in the disease process.
Conclusions:
- Alzheimer disease (AD) may have an immunological basis.
- Activated CD8 T-lymphocytes appear crucial in the immunopathogenesis of AD.
- Further research into immune system involvement in AD is warranted.

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...

01:22Alzheimer's Disease: Treatment
Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...
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...
01:23Alzheimer 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...
01:22Dementia 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...
