voluntary Autonomic nervous system Sends messages from the CNS to the smooth muscle,

cardiac muscle, and certain glands; involuntary

Presenter
Presentation Notes
The nervous system functions as a switchboard for the body. It receives messages from the environment and transfers them to the brain for interpretation and action.

Presentation Notes
As the body ages, there is a gradual reduction in the effectiveness of neurological functioning. An estimated 1% loss of neurons occurs after age 50. Outline the implications when factoring in this loss for an adult at age 65. Ask those who have grandparents to estimate their ages and discuss the implication of a 1% loss in neurons for them. What safety implications arise when considering the neurological changes in an older adult?

injury Anticonvulsant medications Surgery Removal of brain tissue where

seizure occurs

Presenter
Presentation Notes
Seizures have predictable stages. The seizure might begin with an aura (the predictor of the seizure), followed by the ictal phase (seizure), and ending with the postictal period. An estimated 50% of people experience auras. An aura is a sensation that indicates impending seizure activity. Auras are individualized and can include psychic, olfactory, visual, auditory, or taste hallucinations. What is the value of an aura? What should the patient do after experiencing the aura? After the seizure activity ends, a patient might experience a postictal period. The postictal period can be characterized by feelings of fatigue, lethargy, and disorientation.

Guillain-Barré syndrome involves the loss of myelin sheaths in the peripheral nervous system. Myelin acts as insulation for nerves, and the loss of myelin results in alterations of nerve conduction. Although no exact cause has been pinpointed, commonality has been noted between at least 50% of people diagnosed. Review this “common ground.”

injury Spinal shock Autonomic dysreflexia Sexual dysfunction

Presenter
Presentation Notes
The level of spinal cord injury will determine the degree of functioning lost. The higher the injury, the greater the loss. Outline the types of impairments that would be associated with injuries to the cervical, thoracic, lumbar, and sacral regions. Spinal shock is a common early occurrence in most spinal cord injuries. What additional needs might the patient have during this period? Autonomic dysreflexia is a serious complication experienced when damage at or above T-6 occurs. Review the signs and symptoms of autonomic dysreflexia. What stimuli can promote this problem?
