  2. Introduction Cognitive ability is very important in having reasonably high heredity and being stable over the course of a lifetime. In other words, both shared and non-shared environments during the prenatal period, infancy, and childhood, as well as correlated and evoked environments that become increasingly non-shared in adolescence and adulthood, all play a significant role in the emergence and flourishing of cognitive abilities.
  3. WHAT IS COGNITIVE ABILITY? One of the well-researched areas of behavioral genetics is cognitive ability. For humans to adapt and survive, cognitive ability, often known as general intelligence, is crucial. The ability to “the reason, plan, solve problems, think abstractly, absorb complicated concepts, learn quickly and efficiently, and learn from experience," are all included in cognitive ability. The capacity to analyze events, determine what is required, and plan a course of action is supported by intelligence, which goes beyond memorization. Cognitive ability is tightly linked to results in terms of work, occupation status, and health
  4. HOW DOES COGNITIVE ABILITY PLAY THE ROLE TO PREVENT BRAIN AGING? We carry out hundreds of cognitive processing every day without much awareness of the effort required. These activities might include identifying colors, recalling names, or keeping track of time on a watch. Functional magnetic resonance imaging (fMRI) tests of brain activity reveal that the brain’s most active regions change depending on the job at hand. The statistics support what scientists have long suspected: that our brain processes are made up of a variety of unique cognitive abilities.
  5. HOW DOES COGNITIVE ABILITY PLAY THE ROLE TO PREVENT BRAIN AGING? Cognitive Abilities evolve over time, initially as a consequence of brain development and then as a result of the aging of brain cells and the billions of intricate connections that connect them. People’s motions and reflexes slow down as they get older, and their hearing and eyesight deteriorate. Prior to the 1990s, the majority of aging research focused on persons under the age of 80. Recent studies that take into account the rapidly expanding 80-and-older population have improved our knowledge of how the elderly’s cognitive abilities. In a recent study, researchers sought to determine when cognitive performance peaks. Research has found that there is substantial variation in the ages at which cognitive abilities peak and deteriorate with time
  6. 1. KEEP HEALTHY CHOLESTEROL AND BLOOD PRESSURE LEVELS Many elderly people are shocked to find that heart disease and Alzheimer’s disease contain some risk factors not just physically but mentally too. However, if you consider how the brain receives blood from the vascular system, it seems obvious that impaired blood flow might cause brain tissue damage. Long-term hypertension can harm the tiny brain arteries because they are vulnerable to blood pressure increases. The relationship between blood pressure and brain health is supported by many research. Higher blood pressure is associated with impaired cognitive function and brain tissue damage.
  7. 2. EXAMINE YOUR VITAMIN D INTAKE Cognitive impairment is associated with low vitamin D levels. The development of memories is aided by vitamin D. Numerous studies have linked vitamin D insufficiency to a higher risk of dementia or cognitive decline in older persons. Between 30 and 45 ng/ml of vitamin D is considered ideal. Additionally, the vitamin controls the flow of glucose and calcium into and around the brain. It may help safeguard cognition by lowering inflammation and boosting the availability of certain neurotransmitters and brain chemicals.
  8. 3. CONSUME BRAIN- SUPPORTING SUPPLEMENTS. VITAMIN B12 WITH OMEGA-3 DHA A crucial step in avoiding neurodegenerative illnesses later in life is maintaining enough amounts of the omega-3 fatty acid DHA in the brain. According to studies, greater levels of circulating omega-3 DHA and consumption are linked to bigger brain volumes and a lower risk of Alzheimer’s disease. Age increases the risk of vitamin B12 deficiency; roughly 20% of persons over 60 have insufficient or inadequate levels of the vitamin.
  9. 4. LIMIT THE AMOUNT OF RED MEAT AND OTHER ANIMAL PRODUCTS YOU CONSUME Red meat contains significant levels of the important minerals copper and iron, which build up in the body over time and, in excess, can damage the brain. Instead, you may get them at safe levels by choosing healthier alternatives like edamame, sesame and pumpkin seeds, and other beans. In addition to causing amyloid-beta plaque to develop in the brain, excess copper and iron also contribute to oxidative stress in the brain.
  10. 5. PUT A PRIORITY ON WHOLE PLANT FOODS A reasonable guideline is to consume at least 90% whole plant foods, such as fruits, vegetables, legumes, nuts, and seeds. A diet richer in these nutrients and lower in meat and dairy is linked to a 36% lower incidence of Alzheimer’s disease. A big salad as your entrée should be consumed at least once a day to increase your intake of raw veggies and ensure that your diet is rich in natural, nutritious plant foods. Include beans, tomatoes, raw onions, and a salad dressing made of nuts or seeds.
  11. 6. CONSUME BERRIES OFTEN The oxidative stress and inflammation in the brain may be lowered by phytochemicals in fruits and vegetables, which would lower the risk of Alzheimer’s disease. Particular focus has been placed on berries for their ability to protect the brain. Animal studies have shown that a variety of berries can prevent or repair age-related impairments in brain function. In human trials, blueberries and pomegranates have demonstrated encouraging outcomes, suggesting that these phytochemical-rich meals may support memory enhancement in older persons
  12. 7. MAKE NUTS AND SEEDS YOUR MAIN SOURCES OF FAT According to research, eating nuts, particularly walnuts, may improve brain function. ALA, an important omega-3 fatty acid found in walnuts and a precursor to DHA and EPA, has been associated in observational studies with improved working memory. Overall greater cognitive performance is linked to higher nut intake.
  13. 8. LIMIT YOUR INTAKE OF SALT High salt consumption stiffens arteries, raises blood pressure, damages the brain’s fragile blood vessels, reduces blood flow to the brain tissue, and raises your risk of cognitive decline. Use herbs, spices, vinegar with taste, no-salt seasoning blends, or a splash of citrus to add flavor to your dish.
  14. 9. AVOID ADDING MORE SUGAR TO YOUR DIET Your cognitive abilities may be hampered by too much sugar, which also raises blood pressure. High sugar intake results in risky blood glucose spikes that can damage blood vessels, and there is evidence that this damage plays a role in the gradual deterioration of brain function. Since memory and concentration problems as well as reduced cognitive ability have been noted, even a single episode of hyperglycemia might be hazardous. Additionally, regular exposure to high glucose levels probably reduces mental function since higher HbA1c levels have been linked to more severe brain shrinkage.
  15. 10. BE ACTIVE AND EXERCISE REGULARLY FOR YOUR COGNITIVE ABILITY Living a balanced life enhances general well-being. At every stage of life, regular exercise has positive impacts on the brain. One potential explanation is that increased blood flow to the brain occurs during physical activity, and regular exercise helps to maintain healthy blood vessels. Physical fitness is linked to higher memory, cognitive function, and response speed in persons over 60. Exercise also encourages the development of additional mitochondria, which are cells’ energy- producing organelles. The risk of Alzheimer’s disease is significantly lowered by high amounts of physical exercise.
  16. CONCLUSION So there are 10 ways you can try to balance your life and improve the cognitive ability that can help you to prevent brain aging. Having such a lifestyle can help you in many ways, not just in cognitive ability and brain aging but also can enjoy your life in a more rejoiced manner. By these 10 techniques, you can find physical and mental balance too.
