Neurological system associated to age
Describe major changes that occurs on the neurological system associated to age. Include changes on central nervous system and peripheral nervous system.
Define delirium and dementia, specified similarities and differences and describe causes for each one.
Sample Solution
- Central nervous system (CNS): The CNS is made up of the brain and spinal cord. As we age, the brain and spinal cord shrink and lose some of their neurons. This can lead to a decline in cognitive function, such as memory and processing speed. The CNS also becomes more susceptible to damage from diseases, such as Alzheimer's disease and stroke.

- Central nervous system (CNS): The CNS is made up of the brain and spinal cord. As we age, the brain and spinal cord shrink and lose some of their neurons. This can lead to a decline in cognitive function, such as memory and processing speed. The CNS also becomes more susceptible to damage from diseases, such as Alzheimer's disease and stroke.
- Peripheral nervous system (PNS): The PNS is made up of the nerves that connect the CNS to the rest of the body. As we age, the PNS can also decline. This can lead to problems with sensation, movement, and coordination. The PNS is also more susceptible to damage from diseases, such as diabetes and multiple sclerosis.
- Brain: The brain loses about 50% of its neurons by the time we reach 80 years old. This can lead to a decline in cognitive function, such as memory and processing speed. The brain also becomes more susceptible to damage from diseases, such as Alzheimer's disease and stroke.
- Spinal cord: The spinal cord also shrinks and loses some of its neurons with age. This can lead to problems with sensation, movement, and coordination. The spinal cord is also more susceptible to damage from diseases, such as injuries and multiple sclerosis.
- Sensory nerves: The sensory nerves that carry information from the body to the brain can also decline with age. This can lead to problems with sensation, such as numbness and tingling.
- Motor nerves: The motor nerves that carry information from the brain to the body can also decline with age. This can lead to problems with movement, such as weakness and tremors.
- Eat a healthy diet. A healthy diet that is rich in fruits, vegetables, and whole grains can help to protect your brain health.
- Exercise regularly. Exercise is good for the brain and can help to improve cognitive function.
- Get enough sleep. Sleep is essential for brain health and can help to protect against cognitive decline.
- Manage stress. Stress can have a negative impact on brain health, so it is important to find ways to manage stress.
- Stay mentally active. Learning new things and challenging your brain can help to keep it healthy.
- Get regular checkups. It is important to see your doctor regularly for checkups so that they can monitor your brain health and identify any potential problems early on.
