Greater decreases in overall brain volume in later adulthood is associated with an unclear exact relationship in cognitive abilities and cognitive functioning.
<h3>How brain changes in late adulthood?</h3>
The brain's size reaches roughly 90% of its adult volume by the time a child is six years old. The brain begins to contract in our 30s and 40s, and by the time we reach our 60s, the brain is contracting even more rapidly. The brain begins to change in appearance, just like wrinkles and gray hair do later in life.
The brain actually shrinks and its overall mass decreases as adults. There are decreases in some neurotransmitters as well, including dopamine and acetylcholine. Loss of memory for recent events, familiar names, and familiar duties is the first sign of Alzheimer's disease. In old age, general knowledge memory does not deteriorate. There has been a deterioration in episodic and event memory.

The correct answer to the question: The pineal body secretes which hormone that maintains the body´s internal clock, the 24-hour wake-sleep cycle, and regulates the onset and duration of sleep?, would be, C: Melatonin.
Explanation:
The process of sleep and wakefulness, also called the circadian cycle, its a pretty complex system that is controlled by several parts of the brain, but most importantly, structures of the diencephalon (vital is the hypothalamus), the pineal gland, and the stem of the brain. All these structures, and some others, respond to changes both in light perception by the eyes and other senses, heat, and homeostatic balances. These factor play a vital role in telling the human body that it is time for sleep, or to awaken. The pineal gland, as part of this melody, is essential, as it secretes the hormone, melatonin, in response to light changes. Melatonin will balance out the process of sleep, when it is secreted in high quantities by the pineal gland, and wakefulness, when it is no longer secreted in response to the presence of light. This is what is called the circadian cycle.
