Answer:
As you age, your brain goes through changes that can slow down your thinking: It loses volume, the cortex becomes thinner, the myelin sheath surrounding the fibers of your neurons begins to degrade, and your brain receptors don't fire as quickly. For example, older adults may: Be slower to find words and recall names. Find they have more problems with multitasking. Experience mild decreases in the ability to pay attention. Your brain may not be the same age as your body, and an "older" brain may be linked to an increased risk of dying at a younger age, a new study from the United Kingdom finds.Puberty usually starts some time between age 7 and 13 in girls and 9 and 15 in guys. Some people start puberty a bit earlier or later, though. Each person is a little different, so everyone starts and goes through puberty on his or her body's own schedule. The neurobiological changes associated with getting older, prescribed medication for other conditions and genetic susceptibility (which increases with age) are also factors. There are a number of rarer mental health problems that affect older people too, including delirium, anxiety and late-onset schizophrenia. Another study involving 67 ten-year-olds found no evidence to support claims that Brain Age improves cognitive function better than other means of training one's brain. However, the game states that the best indications of brain age are when the user is at least twenty years of age. Aging involves subtle changes in brain structure, chemistry, and function that commonly begin in midlife. By the time we reach our 60s and beyond, our brains are usually smaller in size, with decreased blood flow and lower levels of neurotransmitters and hormones. The Mini–Mental State Examination (MMSE) or Folstein test is a 30-point questionnaire that is used extensively in clinical and research settings to measure cognitive impairment. It is commonly used in medicine and allied health to screen for dementia. Scientists have long known that our ability to think quickly and recall information, also known as fluid intelligence, peaks around age 20 and then begins a slow decline.The biggest changes typically occur when people are in their 40s and 50s, but they can begin as early as the mid-30s and continue into old age. Even when your muscles are in top working order, they contribute to facial aging with repetitive motions that etch lines in your skin.
