What are neurological diseases?

Neurological disorders are medically defined as disorders that affect the brain as well as the nerves found throughout the human body and the spinal cord. Structural, biochemical or electrical abnormalities in the brain, spinal cord or other nerves can result in a range of symptoms.

What are central nervous system disorders?

Central nervous system diseases, also known as central nervous system disorders, are a group of neurological disorders that affect the structure or function of the brain or spinal cord, which collectively form the central nervous system (CNS).

What does a disease or disorder of the sensory system do?

Sensory disorders involve difficulty processing information from taste, touch, smell, hearing, or sight. These disorders are often found in people who have another IDD diagnosis, such as autism. People who have a sensory disorder may: Have poor coordination and balance.

What is CNS disease?

Central nervous system (CNS) disease is a broad category of conditions in which the brain does not function as it should, limiting health and the ability to function.

What are the functions of the special senses?

Functions of Special Senses. Smell or olfaction is the other “chemical” sense; odor molecules possess a variety of features and, thus, excite specific receptors more or less strongly; this combination of excitatory signals from different receptors makes up what we perceive as the molecule’s smell.

What is the nervous system Factsheet collection?

This collection focuses on conditions associated to the nervous system and sense organs. These comprehensive and concise factsheets are physician-reviewed and reflect the most current, evidence-based information. Relevant sources are provided for each fact sheet.

Which sense of vision requires the most learning?

Vision is the sense that requires the most “learning”, and the eye appears to delight in being fooled; the old expression “You see what you expect to see” is often very true. The accessory structures of the eye include the extrinsic eye muscles, eyelids, conjunctiva, and lacrimal apparatus. Eyelids.

What is the difference between touch sense and vision?

Touch. Touch or somatosensory, also called tactition or mechanoreception, is a perception resulting from activation of neural receptors, generally in the skin including hair follicles, but also in the tongue, throat, and mucosa. Vision is the sense that has been studied most; of all the sensory receptors in the body 70% are in the eyes.
