The document discusses aging changes in the nervous system. As people age, the brain and nervous system undergo natural changes such as losing nerve cells and weight. This can slow nerve cell communication and lead to problems with movement and sensation. While some slowing of thinking is normal, more severe issues like dementia are not and require medical attention. Maintaining mental and physical activity can help the brain stay sharp and reduce cell loss as people age.

Mövzu: Aging changes in the Nervous system


The brain and nervous system are your body's central control center. They control your body's:

Movements

Senses

Thoughts and memories

They also help control the organs such as your heart and bowels.

Nerves are the pathways that carry signals to and from your brain and the rest of your body. The
spinal cord is the bundle of nerves that runs from your brain down the center of your back. Nerves
extend out from the spinal cord to every part of your body.

AGING CHANGES AND THEIR EFFECTS ON THE NERVOUS SYSTEM

As you age, your brain and nervous system go through natural changes. Your brain and spinal
cord lose nerve cells and weight (atrophy). Nerve cells may begin to pass messages more slowly
than in the past. Waste products can collect in the brain tissue as nerve cells break down. This
can cause abnormal changes in the brain called plaques and tangles to form. A fatty brown
pigment (lipofuscin) can also build up in nerve tissue.
Breakdown of nerves can affect your senses. You might have reduced or lost reflexes or
sensation. This leads to problems with movement and safety.

Slowing of thought, memory, and thinking is a normal part of aging. These changes are not the
same in everyone. Some people have many changes in their nerves and brain tissue. Others
have few changes. These changes are not always related to the effects on your ability to think.

NERVOUS SYSTEM PROBLEMS IN OLDER PEOPLE

Dementia and severe memory loss are not a normal part of aging. They can be caused by brain
diseases such as Alzheimer disease, which doctors believe is associated with plaques and
tangles forming in the brain and the buildup of lipofuscin.
Delirium is sudden confusion that leads to changes in thinking and behavior. It is often due to
illnesses that are not related to the brain. Infection can cause an older person to become severely
confused. Certain medicines can also cause this.

Thinking and behavior problems can also be caused by poorly controlled diabetes. Rising and
falling blood sugar levels can interfere with thought.
Talk with your health care provider if you have any changes in:

Memory

Thought

Ability to perform a task

Seek medical help right away if these symptoms occur suddenly or along with other symptoms. A
change in thinking, memory, or behavior is important if it is different from your normal patterns or
it affects your lifestyle.

PREVENTION
Mental and physical exercise can help your brain stay sharp. Mental exercises include:

Reading

Doing crossword puzzles

Stimulating conversation

Physical exercise promotes blood flow to your brain. It also helps reduce loss of brain cells.
