Abstract

Insights

Gender influences cognitive performance in Alzheimer's disease (AD) and Mild Cognitive Impairment (MCI). Accounting for sex differences in memory assessments is crucial for accurate clinical diagnosis of AD.

Area of Science:

  • Neuroscience
  • Cognitive Psychology
  • Gerontology

Background:

  • Amnestic Mild Cognitive Impairment (MCI) is a precursor to Alzheimer's disease (AD).
  • Existing assessments often overlook gender-specific variations in cognitive function.
  • Understanding these differences is vital for early and accurate diagnosis.

Purpose of the Study:

  • To investigate gender differences in verbal and visuospatial episodic memory.
  • To explore how these differences manifest across healthy controls (HC), MCI, and AD populations.
  • To highlight the importance of gender in cognitive reserve and AD diagnosis.

Main Methods:

  • Evaluated 143 participants: 48 HC, 43 MCI, and 49 AD.
  • Assessed verbal and visuospatial episodic memory performance.
  • Utilized Mini-Mental State Examination (MMSE) for cognitive screening.

Main Results:

  • Females with HC and MCI showed superior verbal episodic memory compared to males.
  • Male AD patients demonstrated better visuospatial episodic memory than female AD patients.
  • Significant gender-based disparities were observed in memory task performance.

Conclusions:

  • Cognitive reserve may exhibit gender-specific characteristics.
  • Neuropsychological assessments must consider gender to improve Alzheimer's disease diagnosis.
  • Gender-specific performance patterns are critical for understanding cognitive aging and dementia.

Alzheimer Disease l: Introduction01:29

Alzheimer 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...
Alzheimer's Disease: Overview01:26

Alzheimer'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...
Dementia l: Introduction01:22

Dementia 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...

Alzheimer 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...
Alzheimer's Disease: Treatment01:22

Alzheimer'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...

Dementia

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.
