Alzheimer's Disease: Overview01:26

Alzheimer's Disease: Overview

1.9K
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...

Longitudinal Research

13.6K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Alzheimer's Disease: Treatment

1.1K
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...

Cognitive Development During Adulthood01:30

Cognitive Development During Adulthood

1.0K
Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

Longitudinal Studies01:26

Longitudinal Studies

593
Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...

Pharmacodynamics in Geriatric Patients: Effects of Age01:27

Pharmacodynamics in Geriatric Patients: Effects of Age

294
Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

Area of Science:

  • Gerontology and Neurology
  • Epidemiology
  • Public Health

Background:

  • Aging populations worldwide face increasing risks of dementia and chronic non-communicable diseases.
  • Understanding the interplay of aging, frailty, dependency, and cognitive decline is crucial for effective interventions.
  • The "Aging and Alzheimer" study in Cuba addresses these critical public health challenges in older adults.

Purpose of the Study:

  • To investigate the prevalence and incidence of dementia and its subtypes in an aging Cuban population.
  • To identify risk factors and related conditions contributing to cognitive decline and chronic illnesses in older adults.
  • To gather data on sociodemographic characteristics, frailty, dependency, and healthcare utilization among the elderly.

Main Methods:

  • A prospective, longitudinal cohort study involving 2944 adults aged 65 years and older in Cuba.

  • Biomarker analysis including ApoE4 genotype, complete blood count, glucose, kidney and liver function, and lipid profile.

Main Results:

  • The study provides valuable data on the prevalence and incidence of dementia and associated risk factors in the Cuban elderly.
  • It offers insights into chronic diseases, frailty, dependency, and their impact on the health of older adults.
  • Experiences from fieldwork and family interactions contribute to understanding the challenges faced by older adults and their caregivers.

Conclusions:

  • The "Aging and Alzheimer" study offers a comprehensive dataset on aging, dementia, and chronic illness in a specific population.
  • Findings inform the development of targeted community intervention strategies to mitigate dementia, frailty, and dependency.
  • The study highlights the importance of longitudinal research in understanding and addressing the health needs of aging populations.
