AP PSYCHOLOGY

Detailed explanation-1: -The brain is capable of producing new brain cells at any age, so significant memory loss is not an inevitable result of aging. But just as it is with muscle strength, you have to use it or lose it. Your lifestyle, habits, and daily activities have a huge impact on the health of your brain.

Detailed explanation-2: -Almost 40% of us will experience some form of memory loss after we turn 65 years old. But even if we experience memory loss, chances are still unlikely that we have dementia. For the most part, our memory loss is mild enough that we can still live our day-to-day lives without interruption.

Detailed explanation-3: -Normal brain aging may mean slower processing speeds and more trouble multitasking, but routine memory, skills, and knowledge are stable and may even improve with age. It’s normal to occasionally forget recent events such as where you put your keys or the name of the person you just met.

Detailed explanation-4: -Symptoms of memory loss and difficulty with language and logical thinking often are due to neurodegenerative dementias like Alzheimer disease and vascular dementia, which are common and incurable.

Detailed explanation-5: -Our cerebral cortex, the wrinkled outer layer of the brain that contains neuronal cell bodies, also thins with age. Cortical thinning follows a pattern similar to volume loss and is particularly pronounced in the frontal lobes and parts of the temporal lobe.
