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 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...
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...

Parkinson Disease ll: Pathophysiology

Parkinson disease (PD) is a progressive neurodegenerative disorder primarily affecting movement, with additional non-motor features. Its pathophysiology involves complex interactions among genetic susceptibility, environmental exposures, and cellular dysfunction, including dopaminergic neuron loss, protein aggregation, and mitochondrial impairment.Selective NeurodegenerationA key feature is the degeneration of dopaminergic neurons in the substantia nigra pars compacta, leading to reduced...

Area of Science:

  • Neuroscience
  • Gerontology
  • Biomedical Engineering

Background:

  • Gait decline is a significant issue in aging populations, impacting independence and quality of life.
  • Understanding the relationship between brain structure changes and gait impairment is crucial for developing targeted interventions.

Purpose of the Study:

  • To investigate the longitudinal associations between changes in brain structure and the progression of gait decline in older adults.
  • To determine the relative contributions of brain atrophy and white matter lesion progression to gait impairment.

Main Methods:

  • A longitudinal study involving 225 individuals aged 60-86 from the Tasmanian Study of Cognition and Gait.
  • Magnetic resonance imaging (MRI) was used to assess volumes of gray matter, white matter, hippocampi, and white matter lesions (WML).
  • Gait variables were measured using a computerized walkway, with linear regression analyzing associations between brain changes and gait decline.

Main Results:

  • White matter atrophy correlated with reduced gait speed, step length, and cadence.
  • White matter lesion progression was associated with decreased gait speed and, in older individuals, with reduced step length.
  • Hippocampal atrophy was linked to declines in gait speed and step length, while gray matter atrophy affected cadence in individuals with cerebral infarcts.

Conclusions:

  • This study provides the first longitudinal evidence linking brain atrophy and WML progression to gait decline in older adults.
  • Age and presence of infarcts modify these associations, suggesting a role for reduced physiological and brain reserve.
  • Interventions focused on brain health may be essential for preventing mobility decline in the elderly.
