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.
The human nerve system and brain undergo normal aging changes. Weight and nerve cell loss in the brain and spinal cord (atrophy). It’s possible that nerve cells will start relaying information at a slower rate than before. It is possible for waste products or other substances, including beta amyloid, to accumulate in brain tissue as nerve cells degrade. Plaques and tangles, which are aberrant brain alterations, can occur as a result of this. In addition, nerve tissue can accumulate a fatty brown pigment called lipofuscin (Straub et al., 2022). Damage to the nervous system can impair sensory perception. Your reflexes and sense of touch may be diminished or gone altogether. Congestion and insecurity arise as a result. As we get older, our minds naturally slow down, which can have negative effects on our memory and our ability to learn new things. The degree to which each person experiences these alterations varies. The nerves and brain tissue of certain people undergo extensive alterations. The other ones are mostly the same. These alterations are independent of the consequences on your reasoning. Memory loss and dementia are not natural consequences of becoming older. Plaques and tangles are thought to play a role in neurodegenerative illnesses like Alzheimer’s disease. Delirium is a state of rapid confusion characterized by alterations in both thought and behavior. This is frequently attributable to underlying health problems unrelated to the brain. When an elderly person is sick, they can become very disoriented due to the infection. Cont…
