Post-traumatic stress disorder (PTSD)
|
|
Post-traumatic stress disorder (PTSD) A syndrome caused by re-experiencing traumatic events while being unaware of or unresponsive to current events or, in other words, a "flashback." A child may experience sleeping problems, nightmares, intrusive thoughts, have difficulty concentrating, self-destructive behavior, hyperactivity or anxiety/panic disorder. Therapy is crucial in managing PTSD.
RELATED TERMS--------------------------------------
Syndrome
A grouping of signs and symptoms, based on their frequent co-occurrence, that may suggest a common underlying pathogenesis, course, familial pattern, or treatment selection.
SIMILAR TERMS--------------------------------------
Post
Thin metal rod inserted into the root of a tooth after root canal therapy; provides retention for a "coping" that replaces lost tooth structure and retains crown.
Post partum
Post partum refers to the period after childbirth.
Post stimulus time histogram
A method for examining cell response to a particular stimulus. The time after stimulus onset is divided into a number of bins. The stimulus is then presented repeatedly and the count in each bin increased each time the cell fires during that time bin.
Post-core
Post and buildup to replace lost tooth structure and retain crown.
Post-crown
Single structure that combines post-core and crown.
Postcholecystectomy syndrome
A condition that occurs after gallbladder removal. The muscle between the gallbladder and the small intestine does not work properly, causing pain, nausea, and indigestion. Also called biliary dyskinesia.
Posterior
At or toward the back.
Posterior parietal cortex
Concerned with the perception of the spatial relations among objects.
Postgastrectomy syndrome
A condition that occurs after an operation to remove the stomach (gastrectomy). See also dumping syndrome.
Postmarketing surveillance
ongoing safety monitoring of marketed drugs. See Phase 4 studies, Phase 5 studies.
Postmature
An infant born at 42 weeks or more is considered postmature. As withprematurity, being postmature can lead to complications; the baby may belarger and less able to pass through the birth canal or the placenta may nolonger be able to provide adequate oxygen or nutrition.
Postnatal care
Medical care for both newborn and mother during the first 6 weeks after birth.
Postnatal Depression
Depression in women occurring usually within four weeks after the delivery of a child. The degree of depression ranges from mild transient depression to neurotic or psychotic depressive disorders.
Postoperative
After surgery.
Postpartum
After childbirth.
Postpartum depression
More severe than the more common and milder baby blues, postpartumdepression is characterized by sadness, impatience, restlessness, and inability to care for the baby.
Postprandial
Occurring after a meal. Example: Blood taken 1-2 hours after eating to see the amount of glucose in the blood would be called a postprandial blood glucose test.
Postural Orthostatic Tachycardia Syndrome (POTS) (Neurocardiogenic Syncope, Dysautonomia)
Dysfunction of the autonomic nervous syndrome. Causes symptoms of fatigue, dizziness, increased heart rate, and other symptoms. See syncope.
Postural tremor
A tremor of a limb that increases when the limb is stretched.
Posturography
A force platform that evaluates somatosensory and visual influences on posture and equilibrium.
Postvagotomy stasis
Delayed stomach emptying; occurs after surgery on the vagus nerve.
PREVIOUS AND NEXT TERMS--------------------------------------
Phentermine
A sympathomimetic amine used in attack preparations as a vasoconstrictor and bronchodilator, usually in combination with an antihistamine drug. An appetite suppressant that disrupts the transmission of signals from the neurotransmitters and is used in the management of obesity.
Pyelonephritis
Infection of the kidneys. A severe infection favoured by a slowing in the flow of urine (urinary stasis) between the kidney and bladder, through a long duct called the urethra. This stasis is naturally increased by pregnancy (atonicity of ducts), but the absence of any blockage in the urinary tract or reflex from the bladder and urethras (vesicourethral reflux) should be ascertained.
Panic disorder
Panic disorder is a condition in which persons experience sudden, severe attacks of anxiety. Symptoms consist of heart palpitations, shortness of breath, sweating, dizziness, upset stomach and fear of dying or losing control. Some patients have such attacks only occasionally, while others may have several attacks a day. Since the attacks are very frightening, many patients start to avoid situations in which the attacks have occurred, such as driving on an expressway or over bridges, shopping in large department stores or malls, etc. Agoraphobia is the term for such avoidance, which in severe cases can lead to being completely housebound.
Paresis
It is only an impairment of the action of a muscle or a group of muscles (not a total loss of function).
Paraplegia
Paraplegiai nvolves a loss of sensation and movement in the legs and in part or all of the trunk. This varies according to the level of the injury. Generally, the lower the injury, the less the loss of movement and sensation. Paraplegia usually results from an injury to the spinal cord in the mid and lower back.
Post-traumatic stress disorder (PTSD)
Presbyopia
The eye's gradually decreasing ability to focus on nearby objects. Presbyopia is a normal part of aging and affects virtually everyone, usually becoming noticeable after age 40. People with presbyopia typically hold reading materials at arm's length in order to bring the words into focus. They may experience headaches or eyestrain while reading, viewing a computer screen, or doing close work. Presbyopia can be corrected with reading glasses, bifocal or variable focus lenses, or contact lenses. Using bright, direct light when reading is also helpful.
Psychomotor attack
A form of epilepsy characterized by periodic behaviour disturbances such as chewing and lip smacking, staring and confusion. In some patients, picking at their clothes, or rubbing their hands or legs may occur. Although a psychomotor seizure may present a strange picture, the person experiencing it is usually unaware of the situation.
Phobia
An anxiety disorder that is characterized by an intense and, at least on the surface, irrational fear.
Pemphigus Vulgaris
A serious disease manifesting as large skin and mucosal bullae that burst leaving large painful ulcers; may be fatal.
Primary Biliary Cirrhosis
A rare form of biliary cirrhosis of unknown etiology in which small intrahepatic bile ducts are destroyed while the major intra- and extrahepatic ducts remain patent; 90 per cent of patients are female; most are middle-aged; it is characterized by chronic cholestasis with pruritus, jaundice, hypercholesterolemia and xanthomas, osteomalacia, and, in the later stages, by portal hypertension and liver failure. Almost all patients have circulating antimitochondrial antibodies.
