Dementia is a collective term that refers to a decline in cognitive function, affecting memory, language, and problem-solving abilities. The most common types of dementia are Alzheimer's disease and Parkinson's disease, each of which presents with distinct symptoms and progression patterns.

• Alzheimer's Disease: Characterized by memory loss, confusion, and progressive cognitive decline.
• Parkinson's Disease: Known for motor symptomatology as well as cognitive impairment over time.

While many factors contribute to dementia, a major but often neglected one is insulin resistance. Conditions like pre-diabetes and diabetes significantly elevate the risk of developing dementia.

"A major analysis showed that this has increased up to 127% risk of dementia in people with diabetes."

Given the strong linkage between insulin resistance and dementia, addressing these issues early on might serve as a protective strategy against cognitive decline.

• Lifestyle modifications such as increased physical activity and dietary changes can effectively improve insulin sensitivity.
• Medical interventions may include medication to control blood glucose levels and maintain metabolic health.

Further research is warranted to explore these relationships thoroughly, but current evidence underscores the importance of metabolic health in preventing cognitive disorders.
