Dementia

173
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

675
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...

Parkinson's Disease: Overview

716
Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...

Parkinson's Disease: Treatment

389
Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.
Parkinson's Disease is primarily a result of the loss of dopaminergic neurons in the substantia nigra pars compacta. The cornerstone of...

Alzheimer's Disease: Treatment

265
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...

Summary

Patients with dementia with Lewy bodies (DLB) had significantly higher rates of hospitalizations and emergency department (ED) visits compared to Alzheimer's disease (AD), vascular dementia (VD), and controls. Fall prevention and psychiatric care are crucial for reducing DLB hospitalizations.

Area of Science:

  • Neurology
  • Geriatrics
  • Health Services Research

Background:

  • Dementia with Lewy bodies (DLB) is a progressive neurodegenerative disorder.
  • Understanding healthcare utilization patterns is vital for managing DLB patient care.
  • Early-stage DLB presents unique challenges in healthcare resource allocation.

Purpose of the Study:

  • To characterize hospitalization and emergency department (ED) visit patterns in early-stage dementia with Lewy bodies (DLB).
  • To compare healthcare utilization between DLB patients and those with Alzheimer's disease (AD), vascular dementia (VD), and healthy controls.
  • To identify factors contributing to hospitalizations in DLB.

Main Methods:

  • Analysis of electronic health records and claims data from a U.S. healthcare system.
  • Inclusion of patients diagnosed with DLB (n=175), AD (n=2478), and VD (n=513) up to 3 years pre/post diagnosis.
  • Comparison with matched controls (n=525) using generalized linear models to assess utilization rates and types.

Main Results:

  • DLB patients exhibited significantly higher hospitalization and ED visit rates compared to AD and control groups.
  • DLB patients had more ED visits than VD patients.
  • Hospitalizations associated with falls were over 50% more likely in DLB patients compared to AD and VD patients.

Conclusions:

  • Patients with DLB demonstrate substantially higher utilization of ED services compared to AD, VD, and control groups.
  • DLB patients are more prone to hospitalizations than AD and control groups.
  • Implementing fall prevention strategies and psychiatric interventions may significantly reduce hospitalizations in early-stage DLB.
