An abbreviated example of an exposure hierarchy is pictured in Image 1. Image 1: Exposure hierarchy example for treating public speaking fears. When exposure to an item at the bottom of the hierarchy leads to moderately reduced distress or increased tolerance, a client progresses up the hierarchy to more and more difficult exposures.
Allergen immunotherapy, also known as desensitization or hypo-sensitization, is a medical treatment for environmental allergies (such as insect bites) and asthma. [ 1 ] [ 2 ] Immunotherapy involves exposing people to larger and larger amounts of allergens in an attempt to change the immune system's response.
The principles of systematic desensitization can be used by children to help reduce their test anxiety. Children can practice the muscle relaxation techniques by tensing and relaxing different muscle groups. With older children and college students, an explanation of desensitization can help to increase the effectiveness of the process.
Ideomotor Apraxia, often IMA, is a neurological disorder characterized by the inability to correctly imitate hand gestures and voluntarily mime tool use, e.g. pretend to brush one's hair. The ability to spontaneously use tools, such as brushing one's hair in the morning without being instructed to do so, may remain intact, but is often lost.
In medicine, desensitization is a method to reduce or eliminate an organism's negative reaction to a substance or stimulus. In pharmacology , drug desensitization refers to two related concepts. First, desensitization may be equivalent to drug tolerance and refers to subjects' reactions (positive or negative) to a drug reducing following its ...
On the other hand, inactivating mutations of GRK1 lead to faulty rhodopsin receptor desensitization and are linked to Oguchi disease, a non-progressive form of night blindness. Similarly, single nucleotide polymorphisms in GRK4γ or that cause an increase in G protein-coupled receptor kinase (GRK) activity cause serine phosphorylation and ...
It is estimated that anywhere from nearly 3.5 to 10% of the world's population may have a phobia of needles (trypanophobia), [25] and it is much more common in children, ages 5–17. Topical anesthetics can be used to desensitize the area where the injection will take place to reduce pain and discomfort. [ 26 ]
Stereotypic movement disorder (SMD) is a motor disorder with onset in childhood involving restrictive and/or repetitive, nonfunctional motor behavior (e.g., hand waving or head banging), that markedly interferes with normal activities or results in bodily injury. [1]
