DSM-IV
Diagnostic & Statistical Manual 4th edition, an American handbook for mental health professionals that lists different categories of mental disorders and the criteria for diagnosing them, according to the publishing organization the American Psychiatric Association. It is used worldwide by clinicians and researchers as well as insurance companies, pharmaceutical companies and policy makers. More information available at Wikipedia.
ECT
An acronym for electroconvulsive therapy, a controversial psychiatric treatment in which seizures are electrically induced in anesthetized patients for therapeutic effect. This treatment is most often used in severe depression. More information available at MedlinePlus and Wikipedia.
EMG
Electromyography. A technique for evaluating and recording physiologic properties of muscles at rest and while contracting.
U.S. Food and Drug Administration (FDA) is the federal agency responsible for ensuring that foods are safe, wholesome and sanitary; human and veterinary drugs, biological products, and medical devices are safe and effective; cosmetics are safe; and electronic products that emit radiation are safe. FDA also ensures that these products are honestly, accurately and informatively represented to the public. For more information about the FDA go to http://www.fda.gov/default.htm
Footdrop
Impaired or absent voluntary dorsiflexion of the foot. The normal heel-toe pattern of walking is disturbed, causing the toes to touch the ground before the heel, resulting in tripping and loss of balance.
GAD
General Anxiety Disorder, an anxiety disorder that is characterized by excessive, uncontrollable and often irrational worry about everyday things, which is disproportionate to the actual source of worry. More information available at MedlinePlus and Wikipedia.
GERD
Gastoresophageal Reflux Disease
LP
Lumbar puncture - a diagnostic and at times therapeutic procedure that is performed in order to collect a sample of cerebrospinal fluid
MAOI
MonoAmine Oxidase Inhibitor. A type of antidepressant drug which prevents the breakdown of dopamine. It is also used in Parkinson's disease as the drug selegiline, where in combination with an L-dopa containing drug such as Sinemet, it helps boost the latter's efficacy.
MDD
Major depressive disorder, also called clinical depression, is a common psychiatric disorder, characterized by a pervasive low mood, loss of interest in usual activities and diminished ability to experience pleasure. More information available at MedlinePlus and Wikipedia.
MRI
Magnetic Resonance Imagery A medical imaging technique primarily used in Radiology to visualize the structure and function of the body. It provides detailed images of the body in any plane.
NCS
Nerve Conduction Study. A test commonly used to evaluate the function, especially the ability of electrical conduction, of the motor and sensory nerves of the human body.
NGT
NGT or "NG Tube" is short for "Naso-Gastric Tube", a narrow tube which is threaded through the nostril, down the throat, and into the stomach to allow tube feeding for short periods. Longer-term feeding options include PEG or RIG, which involve insertion of a feeding tube directly into the stomach.
OCD
An acronym for obsessive-compulsive disorder, an anxiety disorder and is characterized by recurrent, unwanted thoughts (obsessions) and/or repetitive behaviors (compulsions). More information available at MedlinePlus and Wikipedia.
ON (Optic neuritis)
Optic neuritis can be a symptom of MS. It is an inflammation of the optic nerve; it is classified as either intraocular, affecting the part of the nerve within the eyeball, or retrobulbar, affecting the portion behind the eyeball.
PEG
An acronym for "Percutaneous Endoscopic Gastrostomy", a surgical procedure to insert a feeding tube into the stomach by means of a tube inserted down the throat (endoscope) to guide the surgeon.
Phase I
Phase I trials are the first part of a medical trial to use human subjects, as opposed to animals in the pre-clinical stage. This phase includes trials designed to assess the safety (pharmacovigilance), tolerability, pharmacokinetics, and pharmacodynamics of a drug and is not intended to test whether the drug does what it's supposed to do. Most Phase I trials take place in healthy volunteers as opposed to people with the condition to be treated.
Phase II
Phase II clinical trials are the first stage of drug development designed to test efficacy and tolerability in patients and at the dosage at which the drug will probably be used clinically. Most drugs that fail clinical trials do so at this stage, usually due to toxicity or adverse events.
Phase III
Phase III clinical trials are the large, expensive studies used to determine a drug's efficacy compared either to an inert (but identical-looking) pill called a placebo. Because the expectations of doctors and patients can affect outcomes, both are "blinded" as to whether each participant is receiving the drug or the placebo. Outcome measures vary according to the nature of the disease but may include survival, functional outcome, and/or quality of life.
PTSD
An acronym for post traumatic stress disorder, an anxiety disorder that can develop after exposure to a terrifying event or ordeal in which grave physical harm occurred or was threatened. Traumatic events that may trigger PTSD include violent personal assaults, natural or human-caused disasters, accidents, or military combat. More information available at MedlinePlus and Wikipedia.
RIG
An acronym for "Radiologically Inserted Gastrostomy", a procedure whereby the stomach is inflated with air whilst a surgeon inserts the feeding tube whilst using a radiological camera to ensure proper placement. RIG is a newer technique than the older PEG system and can be performed quickly and with only local anaesthetic.
SAD
Seasonal affective disorder is a mood disorder, whose sufferers experience normal mental health throughout most of the year, but experience depressive symptoms in the winter. More information available at MedlinePlus and Wikipedia.
SNRI
Serotonin - Noradregernic Reuptake Inhibitor, a class of antidepressant used in the treatment of clinical depression and other affective disorders. They act upon two neurotransmitters in the brain that are known to play an important part in mood, namely, serotonin and norepinephrine. More information available at Wikipedia.
SR
Sustained Release. A formulation of a tablet which releases its active agent slower than the normal pill. Examples include Effexor SR (an antidepressant).
SSRI
Serotonin Specific Reuptake Inhibitor; a class of antidepressant drug which maintains higher levels of the mood-affecting neurotransmitter serotonin. Examples of SSRI's include paroxetine (Seroxat) and Fluoxetine (Prozac). This class of antidepressants is used in the treatment of depression, anxiety disorders, and some personality disorders. More information available at Wikipedia.
