Dementia

709
Dementia is a collective term for cognitive disorders primarily affecting memory, thinking, and reasoning. It is not a specific disease but a syndrome, with Alzheimer's disease being the most common cause, accounting for approximately 60-80% of cases. Other types include vascular dementia, Lewy body dementia, and frontotemporal dementia. Dementia affects millions worldwide, particularly older adults, though it is not a normal part of aging.
The progression of dementia is generally gradual....

Alzheimer's Disease: Overview

2.0K
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...

Association Areas of the Cortex

10.6K
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

Alzheimer's Disease: Treatment

1.2K
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...

Area of Science:

  • Neuroscience and Neurology
  • Genetics and Molecular Biology

Background:

  • Frontotemporal dementia (FTD) comprises behavioral variant FTD (bvFTD) and primary progressive aphasia (PPA).
  • These neurodegenerative diseases primarily affect the frontal and temporal lobes.
  • Recent years show significant progress in clinical characterization and understanding disease mechanisms.

Purpose of the Study:

  • To summarize recent advances in the clinical characterization of FTD.
  • To highlight the impact of new diagnostic criteria and genetic discoveries.
  • To discuss the potential for early diagnosis and treatment of FTD.

Main Methods:

  • Review of updated diagnostic criteria for bvFTD and PPA.
  • Analysis of discoveries in pathogenic mutations and genotype-phenotype interactions.
  • Examination of emerging results from longitudinal studies of familial FTD.

Main Results:

  • Updated diagnostic criteria for bvFTD and PPA have been published.
  • New pathogenic mutations enhance understanding of FTD genotype-phenotype interactions and disease mechanisms.
  • Longitudinal studies indicate that imaging and cognitive changes precede symptom onset in familial FTD.

Conclusions:

  • Advances in FTD research are leading to improved clinical characterization and diagnostic tools.
  • Discovery of early biomarkers through longitudinal studies may facilitate earlier diagnosis.
  • These developments offer hope for shifting the perception of FTD from an untreatable condition to one with potential therapeutic interventions.
