Insights

This review covers current and developing Alzheimer's disease (AD) treatments targeting amyloid plaques and neurofibrillary tangles. Research also explores therapies for AD's inflammatory, oxidative, vascular, and neurochemical pathways.

Area of Science:

  • Neurology
  • Pharmacology
  • Molecular Biology

Background:

  • Alzheimer's disease (AD) is characterized by amyloid plaques and neurofibrillary tangles.
  • Understanding the molecular biology of these hallmarks is crucial for developing effective treatments.
  • Emerging research highlights the roles of inflammation, oxidative stress, vascular factors, and neurochemical changes in AD pathogenesis.

Purpose of the Study:

  • To provide an overview of current and investigational therapeutic strategies for Alzheimer's disease (AD).
  • To discuss treatments targeting the primary pathological hallmarks of AD.
  • To explore therapies addressing secondary mechanisms implicated in AD progression.

Main Methods:

  • Review of marketed and late-stage development treatments for Alzheimer's disease.
  • Analysis of research into the molecular biology of amyloid plaques and neurofibrillary tangles.
  • Discussion of therapeutic targets related to inflammation, oxidative stress, vascular, and neurochemical alterations in AD.

Main Results:

  • Significant progress has been made in understanding the molecular basis of AD pathology.
  • Multiple therapeutic avenues are being pursued, targeting both core hallmarks and associated mechanisms.
  • A range of treatments are currently marketed or in advanced development stages.

Conclusions:

  • Current and future Alzheimer's disease (AD) treatments are multifaceted, addressing key pathologies and contributing factors.
  • Continued research into molecular mechanisms is vital for advancing AD therapeutics.
  • A combination of approaches may be necessary for effective AD management.

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...

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists

Cognitive enhancers, also known as "smart drugs," are substances used to enhance memory, mental alertness, and concentration. These can be natural or synthetic and improve cognition in conditions like Alzheimer's disease (AD) and other neurodegenerative diseases. Some common examples include caffeine, amphetamines, methylphenidate, modafinil, arecoline, donepezil, vortioxetine, and piracetam. These enhancers work on the principle of synaptic plasticity and altered circuit function. They...
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...
Dementia01:30

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.
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...
Cognitive Development During Adulthood01:30

Cognitive Development During Adulthood

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,...
