Previous research has shown a link between obesity and brain health—lower cognitive functioning and higher dementia risk—traditionally using body mass index (BMI). But Beeri’s team notes ...
Pathophysiology of obesity is the study of disordered physiological processes that cause, result from, or are otherwise associated with obesity. A number of possible pathophysiological mechanisms have been identified which may contribute in the development and maintenance of obesity.
Out of 25 anti-obesity medications withdrawn from the market between 1964 and 2009, 23 acted by altering the functions of chemical neurotransmitters in the brain. The most common side effects of these drugs that led to withdrawals were mental disturbances, cardiac side effects, and drug abuse or drug dependence .
Brain alterations associated with mood were more common in women, and things like anxiety and depression could also make a person less motivated to be active, another known driver of obesity.
Relatively speaking, the brain consumes an immense amount of energy in comparison to the rest of the body. The mechanisms involved in the transfer of energy from foods to neurons are likely to be fundamental to the control of brain function. [1] Human bodily processes, including the brain, all require both macronutrients, as well as ...
Being overweight in midlife has been linked to greater risk of developing Alzheimer’s disease or dementia, and a new study shows that brain changes in obese people mirror some of those with ...
The brain's neuronal and glial cells require sufficient nutrients for energy to perform important cognitive functions such as attention and memory, [64] [65] and without a steady supply of nutrients including glucose, fatty acids, and vitamins B1 (Thiamine), neural activation required for memory functions becomes impaired. [65]
Many “failed” obesity interventions are, in fact, successful eat-healthier-and-exercise-more interventions. A review of 44 international studies found that school-based activity programs didn’t affect kids’ weight, but improved their athletic ability, tripled the amount of time they spent exercising and reduced their daily TV ...
