Answer:

Memory decline is a condition in which the brain's function is impaired, or the process of transferring information and memories to the cerebral cortex is disrupted. People experiencing memory decline are often absent-minded, lack focus when studying or working, react slowly to everything, and are no longer able to meet work or study demands. Memory decline can manifest in simple things like forgetting to turn off lights or lock the door when going out. If this condition is not addressed promptly, it can progress to dementia.

Memory decline is common in older adults. From the age of 25 onward, approximately 3,000 brain cells die each day without being replaced. Memory decline is trending towards affecting younger people, partly due to factors like consuming fast food, high-energy food, stimulants, staying up late, and lack of sleep. These factors promote the production of free radicals, increasing the risk of damage to nerve cells, leading to brain damage and subsequent memory decline.

The human body contains white fat and brown fat. In obese individuals, white adipose tissue not only stores excess energy but also secretes a group of substances called adipokines. These substances disrupt endocrine and central nervous system function, increasing the risk of Alzheimer's disease and other memory impairments. Obesity promotes the development of low-grade chronic inflammation in adipose tissue, leading to disruptions in the homeostatic system—a cause of various diseases, including neurodegenerative diseases.

Overweight and obese individuals are prone to gut microbiota imbalances, affecting the gut-brain axis and causing neurodegeneration. The volume of gray matter and the thickness of the cerebral cortex in obese individuals decrease as the body mass index (BMI) increases. These factors negatively impact cognitive function. Weight loss contributes to controlling nerve cell function, enhancing neuronal plasticity, and maintaining energy metabolism and cognitive function.

You should consult a specialist in endocrinology or a weight management and obesity treatment center. The doctor will conduct an examination and order appropriate tests to determine the cause and develop a suitable treatment plan. You should also exercise regularly, limit stress, and maintain a healthy diet, such as reducing high-carbohydrate and sugary foods, and avoiding alcohol, tobacco, and carbonated drinks.
