Abstract

Insights

Neuropsychiatric symptoms (NPS) are common in mild cognitive impairment (MCI) and Alzheimer's disease (AD). Specific NPS like delusions and apathy can help differentiate between MCI and AD in older adults.

Area of Science:

  • Geriatric Medicine
  • Neurology
  • Psychiatry

Context:

  • Neuropsychiatric symptoms (NPS) are prevalent in elderly individuals.
  • Distinguishing between mild cognitive impairment (MCI) and Alzheimer's disease (AD) is clinically significant.
  • The role of NPS in differential diagnosis for cognitive decline requires further elucidation.

Purpose:

  • To describe the prevalence of NPS in elderly patients with MCI or AD.
  • To assess the relevance of specific NPS in differentiating between MCI and AD.
  • To investigate the association between NPS and white matter ischemic lesions (WMIL).

Summary:

  • A study of 179 elderly patients (MCI n=90, AD n=89) found NPS in 74.4% of MCI and 92.1% of AD patients.
  • Depression and apathy were the most common NPS in both groups.
  • The presence of any NPS increased the odds of an AD diagnosis (OR 3.6), with delusions, apathy, disinhibition, and aberrant motor behavior being independent predictors.

Impact:

  • NPS are frequent in both MCI and mild-to-moderate AD.
  • Certain NPS significantly aid in the differential diagnosis between MCI and AD.
  • Findings contribute to improved diagnostic accuracy and patient management in geriatric cognitive disorders.

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: 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...

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: 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 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...

Negative and Cognitive Symptoms of Schizophrenia

Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...
