Nervous System Disorders

Nervous system disorders can be caused by a variety of factors that can affect the health of the nervous system, including lifestyle and environmental factors, such as diet, stress, exposure to toxins, and physical injury. Depending on the cause, nervous system disorders can affect the way the brain, nerves, and muscles communicate and interact, leading to a number of debilitating physical and mental health conditions. The most common type of nervous system disorder is known as neurodegenerative disease, in which brain cells deteriorate and die, leading to a gradual decline in physical, mental, and cognitive functioning. Neurodegenerative diseases include conditions such as Alzheimer’s disease, Parkinson’s disease, and amyotrophic lateral sclerosis (ALS). Symptoms of these disorders can range from gradual memory loss and confusion, to paralysis, tremors, and difficulty speaking or swallowing. Mental health disorders, such as anxiety, depression, PTSD, and ADHD, can also be caused by nerve cell dysfunction and/or disruption in communication between brain cells. These disorders can cause a variety of emotional and physical symptoms, such as extreme fear or loss of motivation, difficulty concentrating and focusing, and problems with sleep. Cerebral palsy is another common nervous system disorder in which motor control is greatly impaired due to damage to the brain. Symptoms can include difficulties walking or even standing, sudden uncontrolled muscle spasms, and difficulty with basic activities such as speaking and eating. A number of other neurological disorders, such as multiple sclerosis, epilepsy, Huntington’s disease, Bell’s palsy, and narcolepsy, can also be caused by changes in the nervous system. Often times, these conditions can impair vision, hearing, and balance as well as motor skills. Treatment for these disorders typically includes medications, surgery, and physical or occupational therapy.
