Alzheimer’s disease is the most common cause of adult-onset dementia. As the upper age brackets of the US population continue to grow, Alzheimer's disease is likely to become an increasingly significant healthcare issue. This module discusses this devastating disease.
An Introduction to Neurological Disorders
This module introduces you to the various categories of neurological disorders. A general understanding of the types of disorders that may occur can give you insight into the diagnostic challenges clinicians face, and can provide useful context when learning about the approaches used to treat these disorders.
Basic Components of the Nervous System
This module first introduces you to the anatomical and functional divisions of the nervous system; then it looks more closely at the fundamental components that comprise the building blocks for nervous system functions. These include nerve cells (neurons), which give rise to nerves, nerve nuclei, and ganglia. This module also discusses the conduction of nerve impulses and the role of various neurotransmitters.
This module discusses the etiology, symptoms, diagnosis, and treatment of migraine.
This module acquaints you with the cause, symptoms, diagnosis, and treatment of Parkinson's disease.
The Autonomic and Somatic Nervous Systems
This module discusses the autonomic nervous system and how its two divisions, the sympathetic and parasympathetic systems, function to support life. It also looks at how the somatic nervous system provides for sensation and enables voluntary and reflexive muscle movement. The diagnostic significance of muscle tone and reflexes is also addressed.
The Central and Peripheral Nervous Systems
This module examines the structure and functions of the central and peripheral nervous systems. It introduces you to the pharmacologic significance of the blood-brain barrier and the role of cerebrospinal fluid in health and diagnostics. It also describes how sensory information travels between the PNS and the CNS and clarifies the significance of various efferent and afferent nerve fibers.
