Leptin in Alzheimer's disease

Area of Science:

• Neuroscience
• Endocrinology
• Gerontology

Background:

• Alzheimer's disease (AD) is the leading cause of dementia in older adults, characterized by amyloid-β plaques and neurofibrillary tangles.
• Obesity is increasingly recognized as an independent risk factor for AD, highlighting the importance of adipose tissue in brain health.
• Understanding the role of hormones like leptin in dementia development is crucial for identifying new diagnostic and therapeutic strategies.

Purpose of the Study:

• To review existing literature on the role of leptin, a hormone produced by adipocytes, in the context of dementia.
• To explore leptin's potential as a predictive biomarker for dementia risk and progression.
• To examine evidence for leptin's neuroprotective effects in Alzheimer's disease.

Main Methods:

• Systematic review of scientific studies investigating leptin and its association with dementia.
• Analysis of research exploring leptin's impact on amyloidogenic processes and tau phosphorylation.
• Evaluation of studies examining leptin's influence on cognitive function in the context of neurodegenerative diseases.

Main Results:

• Leptin evaluation may serve as a more effective predictor of dementia than traditional anthropometric measures.
• Leptin has demonstrated potential neuroprotective activities, including inhibition of amyloidogenesis and reduction of tau phosphorylation.
• Leptin may play a role in improving cognitive function, suggesting a link between metabolic health and brain function.

Conclusions:

• Leptin holds promise as a biomarker for assessing Alzheimer's disease risk and tracking disease progression.
• Leptin's neuroprotective properties warrant further investigation for potential therapeutic applications in dementia.
• Further research into leptin's multifaceted role in brain health is essential for developing effective strategies against dementia.
