Concussion
|
|
Concussion Any alteration in cerebral function caused by direct or indirect (rotation) force transmitted to the head resulting in one or more of the following: a brief loss of consciousness, lightheadedness, vertigo, cognitive and memory dysfunction, tinnitus, difficulty concentrating, amnesia, headache, balance disorder, nausea or vomiting.
RELATED TERMS--------------------------------------
Cerebral
Referring to the cerebrum.
Vertigo
Dizziness.
Cognitive
The mental process of knowing, including aspects such as awareness, perception, reasoning, and judgment.
Memory
In the immune system, memory denotes an active state of immunity to a specific antigen, such that a second encounter with that antigen leads to a larger and more rapid response.
Dysfunction
Difficult function or abnormal function.
Tinnitus
Sounds that are perceived in the absence of any external noise source which may take the form of buzzing, ringing, clicking, pulsations, and other noises. Objective tinnitus refers to noises generated from within the ear or adjacent structures that can be heard by other individuals. The term subjective tinnitus is used when the sound is audible only to the affected individual. Tinnitus may occur as a manifestation of cochlear diseases; vestibulocochlear nerve diseases; intracranial hypertension; craniocerebral trauma; and other conditions.
Amnesia
Loss of memory. Types of amnesia include: anterograde Loss of memory of events that occur after the onset of the etiological condition or agent. retrograde Loss of memory of events that occurred before the onset of the etiological condition or agent.
Headache
Primary - includes tension (muscular contraction), vascular (migraine), and cluster headaches not caused by other underlying medical conditions. Secondary - includes headaches that result from other medical conditions. These may also be referred to as traction headaches or inflammatory headaches.
Balance
A biological system that enables us to know where our bodies are in the environment and to maintain a desired position. Normal balance depends on information from the inner ear, other senses (such as sight and touch) and muscle movement.
Nausea
The feeling of wanting to throw up (vomit).
Vomiting
The release of stomach contents through the mouth.
SIMILAR TERMS--------------------------------------
Concatemer
Multiple copies of a DNA sequence arranged end to end in tandem. Concatenate means to link together in a chain or in a series.
Concatenate
To link together in a chain or in a series. For example, the lymph nodes that appeared enlarged were concatenated, in a row like the links of a chain.
Concentraid
Concentraid is a prescription or over-the-counter drug which is (or once was) approved in the United States and possibly in other countries. Active ingredient(s): desmopressin acetate.
Concentric field
A receptive field divided into an inner circular region and an outer ring-shaped region. Light falling in each of the two regions has opposite effects on the response of the cell.
Conception
When a sperm and egg join to form a single cell, usually in the Fallopiantubes. After joining, the fertilized egg travels into the uterus, where itimplants in the lining on its way to growing into an embryo and then a fetus.
Conceptivity
The proclivity for the physiology and behavior of a male and female to conceive, maintain pregnancy, and progress through parturition, lactation, and the childcare of parenthood
Concerta
Concerta is a prescription or over-the-counter drug which is (or once was) approved in the United States and possibly in other countries. Active ingredient(s): methylphenidate hydrochloride.
Concordance
1. The presence of any given condition such as HIV in both members of a couple. 2. In genetics, the presence of a phenotype such as asthma in both members of a twin pair. 3. In clinical care, agreement between physician and patient.
Concordant
1. Showing concordance, complete agreement. A couple may be concordant for a sexually transmitted infection, with both partners having it. 2. In transplantation genetics, between closely related species. A concordant xenograft is a transplant between members of closely related species.
Concordant couple
A pair of long-term sexual partners in which both partners have a sexually transmitted infection. The CDC has guidelines for counseling concordant couples in which both the man and woman are HIV-infected.
Concrete thinking
Thinking characterized by immediate experience, rather than abstractions. It may occur as a primary, developmental defect, or it may develop secondary to organic brain disease or schizophrenia.
Concussion of the brain
A traumatic injury to the brain as a result of a violent blow, shaking, or spinning. A brain concussion can cause immediate and usually temporary impairment of brain function such as of thinking, vision, equilibrium and consciousness.
PREVIOUS AND NEXT TERMS--------------------------------------
Carpal Tunnel Syndrome
Swelling of the tendons which pass through the wrist and compress the median nerve. Symptoms include pain, numbness and tingling in the hands, primarily the first three fingers and thumb. Symptoms may also appear in the wrist and forearm. CTS symptoms may even wake a person at night.
Celiac Disease
Is a hereditary disorder involving an intolerance to gluten, a protein found in wheat and rye flours. Symptoms include a failure to grow and the passage of fatty, foul-smelling stools that float to the top of the toilet water. The disorder often can be diagnosed on the basis of symptoms and confirmed by examining a small sample of intestinal tissue. As the disease progresses, the fingerlike projections that line the intestinal walls, and from which nutrients are absorbed into the bloodstream, become flattened and smooth. Treatment involves consuming a gluten-free diet.
Cerebral palsy
A variety of disorders resulting from damage to the brain before or during birth or in the first few years of life. Extent of motor involvement varies greatly, from a sight limp or as profound as paralysis, spasticity or speech problems, as well as associated disorders of learning problems, sensory deficits, convulsive and behavioral disturbances of organic origin.
Chronic pain
Chronic pain is medically defined as pain that has lasted 6 months or longer.This constant or intermittent pain has often outlived its purpose, as it does not help the body to prevent injury.It is often more difficult to treat than acute pain.
Colour blindness
The inability to perceive differences between some or all colors that other people can distinguish. It is most often of genetic nature, but might also occur because of eye, nerve, or brain damage, or due to exposure to certain chemicals.
Concussion
Crohn's disease
Crohn's disease is a chronic inflammatory disease of the digestive tract and it can involve any part of it - from the mouth to the anus.It typically affects the terminal ileum as well as demarcated areas of large bowel with relatively normal bowel. It is often associated with auto-immune disorders outside the bowel, such as aphthous stomatitis and rheumatoid arthritis.
Cystic fibrosis
A disease that most commonly affects the lungs and digestive system, especially the pancreas. It causes the exocrine glands, which produce mucus and sweat, to produce abnormal secretions. CF causes the cells in the lung tissue to produce an abnormal amount of thick, sticky mucus that clogs the airways of the lungs, resulting in pulmonary obstructions and life-threatening bacterial infections.
Colitis
Inflammation of the large intestine (colon), especially of its mucous membranes. Spastic colitis is commonly "nervous," or psychosomatic, in origin and is usually a temporary upset rather than a chronic inflammation; this disorder may account for 50 percent of all digestive-tract illnesses. Its symptoms are abdominal pain, diarrhea (sometimes alternating with constipation), and erratic frequency of bowel movements. Treatment of this disorder is basically supportive and psychological in approach.
Corticosteroid
Hormones produced by the adrenal gland which are important to almost every function of cells and organs. They are divided into two groups: glucocorticoids and mineralocorticoids. Glucocorticoids regulate protein, carbohydrate, and fat metabolism. Mineralocorticoids regulate electrolyte balances.
Cardiolipin
One of the components of a cell membrane.
