The nervous system is responsible for the coordination and regulation of an individual's body activities. There are two primary divisions of the nervous system: the peripheral and central nervous systems. The peripheral nervous system consists of all of the nerves and neural elements around the body that are not part of the spinal cord and brain. The central nervous system refers to all the nerves and neural components in the spinal cord and brain. Other elements of the nervous system include the ears, smell sensory organs, skin sensory receptors, eyes, taste sensory organs, and muscle sensory receptors.
Nervous system disorders mean there is an issue with the function or structure of something in the nervous system. Treating nervous system issues often means taking medications, such as anti-seizure meds and corticosteroids. Plasma exchange and physical therapy for nervous system disorders are also common.
Alzheimer's disease is a progressive neurological disorder. It causes an individual's brain cells to degenerate. Alzheimer's disease is the result of lifestyle, genetic, and environmental factors that damage the brain tissues over time. The hallmark symptom of Alzheimer's disease is memory loss, beginning with forgetting conversations and recent events. Eventually, an affected individual will start to repeat questions and statements, misplace possessions, get lost in familiar places, and forget the names of everyday objects. They will also forget the names of family members and be unable to put together the right words to express what they want to say. Multitasking becomes difficult, and an inability to concentrate develops. The ability to make reasonable judgments and decisions deteriorates, and routine activities become difficult.
An Alzheimer's disease diagnosis is made with a neurological exam, lab testing, and mental status tests. Neuropsychological testing and brain imaging are also necessary. Treatment includes medications to slow the disease's progression and supportive care for mental and behavioral symptoms.
