A person’s ability to self-reflect is associated with cognition and glucose metabolism later in life, according to research.
Those who engage in more self-reflection have improved cognition, better overall brain health, and increased glucose metabolism.
The study found that older adults who engage in self-reflection may have a reduced risk of dementia. While the exact causal relationship needs further investigation, self-reflection appears to be a valuable tool for maintaining cognitive health as we age.
Glucose, a form of sugar, serves as the primary energy source for every cell in the body, including neurons in the brain.
Here’s how it impacts brain health:
Brain Energy Demand: The brain is energy-demanding, using approximately half of all sugar energy in the body. Brain functions like thinking, memory, and learning are closely linked to glucose levels. When there isn’t enough glucose, neurotransmitters (chemical messengers) aren’t produced, leading to communication breakdown between neurons.
Hypoglycemia and Cognitive Function: Hypoglycemia (low blood glucose levels) can occur in diabetes. It results in poor attention and cognitive function due to insufficient energy supply for brain function.
Excess Glucose and Cognitive Deficiencies: Excessive glucose consumption has been linked to memory and cognitive deficits. Animal studies suggest that both fructose and glucose may impact brain health.
Diabetes and Brain Consequences: Long-term diabetes (type 1 or type 2) affects brain connectivity, brain matter, and can lead to atrophy. High blood glucose levels may cause small-vessel disease, restricting blood flow and potentially leading to vascular dementia.
Researchers are exploring ways to mitigate these effects, including intranasal insulin (INI) to improve brain function in people with type 2 diabetes.
