Neurological changes refer to alterations in the structure and function of the nervous system, which includes the brain, spinal cord, and nerves. These changes can occur due to various factors such as aging, injury, disease, or environmental influences. For example, conditions like Alzheimer's disease can lead to the degeneration of brain cells, affecting memory and cognitive abilities. Additionally, neurological changes can result from lifestyle factors, such as exercise and diet, which can influence brain health. Neuroplasticity, the brain's ability to reorganize itself by forming new connections, plays a crucial role in recovery from injuries and adapting to new experiences.
