Neuroscientists have estimated that most of the people in their late middle age will lose an average of 11 percent of brain cells every year. Memory decline when the connections between brain cells that store and transfer information in the brain are weakened.
According to Dr. George Rebok, a professor of psychiatry, says that memory changes with age. He also stated that memory decline due to daily mental activities such as remembering other people's name or events. When a person ages, there are more information needed to be store in the brain. It has become a burden for the brain to support without regular activity and thus the information become difficult to access.
Besides that, dementia is another cause of memory decline. Dementia is used to describe a person who has difficulties in thinking, problem-solving or memory loss. Dementia can affect a person’s daily life. It occurs when the brain is damaged by stroke or diseases like Alzheimer's disease.
Quality and quantity of sleep can affect memory function. Lack of sleeping or waking up frequently at night can affect the ability to consolidate information. Depression and stress can affect memory function too. When a person is stressed or depressed, he or she has more difficulty in focusing or paying attention. Their minds have been over stimulated and thereforereduce brain memory function.
A study has shown that it is more difficult for a smoker to put faces with name compare to nonsmoker. This proves that smoking can cause memory decline by reducing the amount of oxygen needed by the brain. A person who suffers from stroke may have short-term memory loss, not being able to recall recent activities. Lastly, Vitamin B1 and B12 deficiency is also shown to affect memory functions.
Stroke is cause by the blockage of blood vessel in the brain or leakage of vessel, both resulting in lowering blood supply to the brain. A balanced diet can helps to reducing the risk of getting stroke. Food with high levels of vitamin B1 and B12 or high quality of proteins and fats is good for the brain too. Exercise does not only help preventing blockages of brain blood vessels, but also increase the supply of blood to the brain, enhancing the development of new neurons and increasing the connection between the brain cells.
Apart from physical activities, mental activities like reading, playing board games or puzzles can also sharpen the ability to focus more. As mentioned earlier, sleep plays an important role in consolidating memories. Therefore, we should always have enough sleep, which is about 7-9 hours of sleep a day to avoid memory decline. Nutritional supplements that contains citicoline are effective for memory improvemen. It helps to boost memory, improve learning and protects the brain from memory decline.
