Obesity, diabetes, and liver disease are linked to cognitive impairment through insulin resistance. Understanding these connections can help endocrinologists treat neurodegeneration.
Area of Science:
- Metabolic disorders and neurodegenerative diseases.
Background:
- Obesity, diabetes, nonalcoholic fatty liver disease, and Alzheimer disease have increased significantly in recent decades.
- These conditions share a commonality in target-organ insulin resistance, leading to cellular degeneration.
- Insulin resistance drives molecular and biochemical changes that contribute to tissue damage over time.
Purpose of the Study:
- To explore the fundamental links between peripheral insulin resistance diseases and cognitive impairment.
- To discuss how metabolic dysfunction contributes to neurodegeneration and Alzheimer disease.
Main Methods:
- Review of current scientific literature on insulin resistance and related diseases.
- Analysis of pathophysiological and pathogenetic mechanisms connecting metabolic and neurological conditions.
Main Results:
- Peripheral insulin resistance is a key factor linking metabolic diseases to cognitive decline.
- Shared molecular and biochemical pathways underlie the degeneration observed in these diverse conditions.
Conclusions:
- Endocrinologists and diabetologists can play a vital role in managing these interconnected diseases.
- An integrated diagnostic and treatment approach is needed for conditions sharing common roots in insulin resistance.
