Summary
Cannabinoids show promise for Alzheimer's disease treatment by protecting brain cells and reducing inflammation. They may also support brain repair mechanisms, offering a multi-faceted therapeutic approach.
Area of Science:
- Neuroscience
- Pharmacology
Background:
- Alzheimer's disease (AD) is a neurodegenerative disorder characterized by cognitive decline, beta-amyloid plaques, and tau hyperphosphorylation.
- Neuroinflammation, oxidative stress, and excitotoxicity are key pathological features of AD.
- The endocannabinoid system is altered in Alzheimer's patients, suggesting its involvement in disease pathophysiology.
Purpose of the Study:
- To review the neuroprotective potential of cannabinoids in Alzheimer's disease.
- To explore how cannabinoids may mitigate AD symptoms and progression.
- To evaluate the cannabinoid system as a therapeutic target for AD.
Main Methods:
- Review of existing literature on cannabinoids and Alzheimer's disease.
- Analysis of studies investigating cannabinoid effects on beta-amyloid and tau pathology.
- Examination of research on cannabinoid-induced neuroprotection, anti-neuroinflammation, and neurogenesis.
Main Results:
- Cannabinoids protect neurons from beta-amyloid toxicity and reduce tau phosphorylation.
- Cannabinoids mitigate oxidative stress and neurodegeneration associated with beta-amyloid.
- Delta 9-tetrahydrocannabinol can inhibit acetylcholinesterase and limit amyloidogenesis.
- Targeting cannabinoid receptors may reduce neuroinflammation without psychoactive effects.
Conclusions:
- Cannabinoids offer a multi-faceted therapeutic strategy for Alzheimer's disease.
- They provide neuroprotection, reduce neuroinflammation, and support intrinsic brain repair mechanisms.
- The cannabinoid system presents a promising therapeutic target for Alzheimer's disease treatment.

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...
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 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...
Chemotherapy-Induced Nausea and Vomiting: Cannabinoids
Tetrahydrocannabinol (THC) is a phytocannabinoid that primarily interacts with the CB1 receptor, a type of G protein-coupled receptor (GPCR) predominantly in and around the chemoreceptor trigger zone (CTZ) and emetic center. THC also blocks the serotonin receptor activity in the dorsal vagal complex (DVC) by inhibiting serotonin release. THC exerts its anti-emetic effects through these interactions, which are beneficial for patients undergoing chemotherapy.

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...
