Normal aging of the nervous system, defined as aging changes that occur in individuals free of overt diseases of the nervous system, is characterized by slow, sometimes continous changes in specific functions. A variety of studies have shown that there is little or no change withe age in certain functions, such as store of informatoin. In contrast, there is a continual loss in the speed of learning, speed of processing new informatoin, and speed of reaction th simple or complex stimuli. There is a loss of sensory functions, especially vibration sense. Muscle strength and motor efficiency decrease. In general, the same neurological diseases that affect all adults may also affect elderly persons, but there are some distinctions to be made. Elderly persons are more likely to have comorbid disease state that can be synergistic with the presenting neurological disorder. Furthermore, personal and professional experience solidifies our underlying sense that the elderly patient is fundamentally differnt in terms of neurological capacity.
