Summary
Research on Alzheimer disease (AD) shows neuronal death is central. This article examines how intracellular free calcium regulation may cause cell death and AD neuropathology, highlighting the need for treatments.
Area of Science:
- Neuroscience
- Cell Biology
- Pathology
Background:
- Alzheimer disease (AD) research has advanced significantly over 12 years.
- Growing evidence links neuronal death to the fundamental problem in AD.
- The exact causes of AD remain unclear, presenting a complex neurochemical puzzle.
Purpose of the Study:
- To re-evaluate the role of intracellular free calcium regulation in neuronal cell death.
- To explore the connection between calcium dysregulation and Alzheimer disease neuropathology.
- To identify potential therapeutic targets for ameliorating AD symptoms and slowing disease progression.
Main Methods:
- Review and re-evaluation of existing research on intracellular calcium homeostasis.
- Analysis of studies linking calcium dysregulation to neuronal apoptosis and AD pathology.
- Synthesis of evidence regarding the neurochemical mechanisms underlying AD.
Main Results:
- Intracellular free calcium dysregulation is strongly implicated in neuronal cell death pathways.
- Calcium dysregulation contributes significantly to the neuropathological hallmarks of Alzheimer disease.
- Understanding calcium's role is crucial for developing effective AD interventions.
Conclusions:
- Intracellular calcium regulation is a critical factor in Alzheimer disease pathogenesis.
- Targeting calcium pathways may offer a promising strategy for treating AD.
- Further research is needed to fully elucidate the complex neurochemical mechanisms of AD.

01:30Cognitive 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...
01:26Alzheimer'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...

01:22Alzheimer'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...
01:29Alzheimer 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...
01:23Alzheimer 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...
01:22Dementia 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...
