Synonyms for dysesthesia or Related words with dysesthesia
Examples of "dysesthesia"
is characterized by pain or burning sensations on or under the surface of the cranial skin. Scalp
may also present as excessive itching of the scalp.
Antidepressants are also often prescribed for scalp
Scrotodynia is a condition characterized by
of the scrotum.
Patients suffering from
can become incapacitated with pain, despite no apparent damage to the skin or other tissue. Patients suffering from
also often suffer from psychological disorders.
is similar to phantom limb syndrome, they should not be confused. In phantom limb, the sensation is present in an amputated or absent limb, while
refers to discomfort or pain in a tissue that has not been removed or amputated. The dysesthetic tissue may also not be part of a limb, but part of the body, such as the abdomen. The majority of individuals with both phantom limb and
experience painful sensations.
is a cutaneous condition characterised by pain and burning sensations without objective physical examination findings.
Daily oral muscle physical therapy, or the administration of antidepressants have been reported as effective therapy for occlusal
patients. Tooth grinding, and the replacement or removal of all dental work should be avoided in patients with occlusal
, despite the frequent requests for further surgery often made by these patients.
There are a number of hypotheses regarding the basis of occlusal
. Some researchers believe the disorder is a psychological one, while others believe it to be a psychosomatic disorder. Joseph Marbach hypothesized that the symptoms were rooted in psychiatric disorders. Marbach suggested that occlusal
would occur in patients with underlying psychological problems (such as schizophrenia) after having undergone dental treatment. More recently, two studies have found that occlusal
is associated with somatoform disorders in which the patients obsess over the oral sensations.
should not be confused with anesthesia or hypesthesia, which refer to a loss of sensation, or paresthesia which refers to a distorted sensation.
is distinct in that it can, but not necessarily, refer to spontaneous sensations in the absence of stimuli. In the case of an evoked dysesthetic sensation, such as by the touch of clothing, the sensation is characterized not simply by an exaggeration of the feeling, but rather by a completely inappropriate sensation such as burning.
It is sometimes described as feeling like acid under the skin. Burning
might accurately reflect an acidotic state in the synapses and perineural space. Some ion channels will open to a low pH, and the acid sensing ion channel has been shown to open at body temperature, in a model of nerve injury pain. Inappropriate, spontaneous firing in pain receptors has also been implicated as a cause of
Late stage symptoms can include an indurated area, paresthesia or
of the tongue or lips, airway obstruction, chronic serous otitis media, otalgia, trismus, dysphagia, cervical lymphadenopathy, persistent pain or referred pain and altered vision.
can generally be described as a class of neurological disorders. It can be further classified depending on where it manifests in the body, and by the type of sensation that it provokes.
is characterized by discomfort or pain from touch to the skin by normal stimuli, including clothing. The unpleasantness can range from a mild tingling to blunt, incapacitating pain.
Similarly, Marbach later proposed that occlusal
may be caused by the brain “talking to itself,” causing abnormal oral sensations in the absence of external stimuli. According to this model, the symptoms of
are catalyzed by dental “amputation,” for example the extraction of a tooth, whereby the brain loses the ability to distinguish between its memory of the bite and the actual, new bite. The patient, unable to recognize his or her own bite, becomes especially attentive to these perceived oral discrepancies. Finally and most recently, Greene and Gelb suggested that instead of having a psychological root,
may be caused by a false signal being sent from the peripheral nervous system to the central nervous system. However, the reviewers note that no method exists for determining sensor nerve thresholds, and so sensory perception in the mouth is often measured by interdental thickness discrimination (ITD), or the ability to differentiate between the sizes of objects (thin blocks) placed between teeth. In one study, occlusal
patients showed greater ability to differentiate these thicknesses than control, healthy individuals, but these differences were not statistically significant.
(or dysaesthesia) comes from the Greek word "dys", meaning "not-normal" and "aesthesis", which means "sensation" (abnormal sensation). It is defined as an unpleasant, abnormal sense of touch. It often presents as pain but may also present as an inappropriate, but not discomforting, sensation. It is caused by lesions of the nervous system, peripheral or central, and it involves sensations, whether spontaneous or evoked, such as burning, wetness, itching, electric shock, and pins and needles.
can include sensations in any bodily tissue, including most often the mouth, scalp, skin, or legs.
Patients with painful disorders of sensation (
) of the soles of the feet may have a similar gait but do not have foot drop. Because of the extreme pain evoked by even the slightest pressure on the feet, the patient walks as if walking barefoot on hot sand.
Cordotomy can be highly effective in relieving pain, but there are significant side effects. These include
(abnormal sensation), urinary retention and (for bilateral cervical cordotomy) apnoea during sleep (acquired central hypoventilation syndrome) caused by inadvertent division of the reticulospinal tracts.
, or "phantom bite," is characterized by the feeling that the bite is "out of place" (occlusal dystopia) despite any apparent damage or instability to dental or oromaxillofacial structures or tissue. Phantom bite often presents in patients that have undergone otherwise routine dental procedures. Short of compassionate counseling, evidence for effective treatment regimes is lacking.
Phantom pain refers to dysesthetic feelings in individuals who are paralyzed or who were born without limbs. It is caused by the improper innervation of the missing limbs by the nerves that would normally innervate the limb.
is caused by damage to the nerves themselves, rather than by an innervation of absent tissue.
Rarely, coexisting vasculitis may cause neurological complications. These occurrences can start with mild headaches that steadily increase in pain and threshold and include attacks of
. It has been found that this type of deterioration happens usually if the lesions involve the fovea.
