Neurological changes refer to alterations in the structure or function of the nervous system, which includes the brain, spinal cord, and nerves. These changes can be caused by various factors, such as aging, disease, injury, or environmental influences. Research in this area aims to understand the mechanisms underlying these changes and how they impact cognitive and motor functions, emotions, and behaviors. This research also seeks to develop novel interventions and treatments to reverse or mitigate negative neurological changes and improve overall brain health.
