Lifestyle Diseases that Affect Your Brain
Lifestyle diseases are diseases that occur primarily as a result of your daily habits. Some of the main contributing factors include: bad food habits, physical inactivity, stress, and an aging biological clock.
Diabetes (A Model of Accelerated Aging)
The connection between type 2 diabetes and Alzheimer’s disease or other forms of dementia are real and strong. Experts are now referring to the progression from type 2 diabetes to Alzheimer’s disease and other forms of dementia to type 3 diabetes or brain diabetes. It occurs when neurons in the brain become unable to respond to insulin which is essential for memory and learning.
There is considerable evidence that diabetes is related to brain diseases. Younger diabetics suffer a variety of degenerative diseases earlier and with greater severity than non-diabetics and seem to age more rapidly than normal. People with type 2 diabetes are 50-65% more likely to develop Alzheimer’s disease than people with normal blood sugars.
Coronary Artery Disease
Research shows if you get cardiovascular disease, it is likely to affect your cognitive function. Plaque builds up in your brain as well as your heart. Unhealthy patterns of cholesterol disrupt communication between nerve cells in your brain and contribute to memory and mental destruction.
As the population ages, it is expected that dementia incidences will increase 400% in the next 20 years. A 27-year study found obese people were 74% more likely to have dementia, while overweight people were 35% more likely.
Possible speculation is that substances such as leptin, a hormone released by visceral or “belly” fat may have some adverse effects on the brain. Leptin plays a role in appetite regulation but also in learning and memory.
