symptom

A subjective perception suggesting bodily defect or malfunction. Symptoms are never perceptible by others. Objective indications of disease are called signs.

sign 

Objective evidence of a disease as distinguished from symptom, which is a subjective complaint of a patient. See diagnosis; prognosis.
Argyll Robertson sign See Argyll Robertson pupil.
Bell's sign Bell's phenomenon occurring on the affected side in Bell's palsy.
Bjerrum's sign See Bjerrum's scotoma.
Cogan's lid twitch sign A twitch of the upper eyelid in an eye with ptosis when the patient is asked to look in the primary position following a downward look. The eyelid then returns to its ptosis position. This condition occurs in myasthenia gravis.
Collier's sign Unilateral, or more commonly bilateral, eyelid retraction that exposes an unusual amount of the sclera of the eye above and below the iris; it gives the person a frightened or startled expression. It is due to a midbrain lesion. See Parinaud's syndrome.
sign convention A set of conventions regulating the direction of distances, lengths, and angles measured in geometrical optics. The most common is the New Cartesian Sign Convention. It stipulates: (1) All distances are measured from the lens, refracting surface or mirror. Those in the same direction as the incident light, which is drawn travelling from left to right, are positive. Those in the opposite direction are negative. (2) All distances are measured from the axis. Those above are positive. Those below are negative. (3) Angles are measured from the incident ray to the axis, with anticlockwise angles positive and clockwise angles negative. (4) The power of a converging lens is positive and that of a diverging lens is negative (Fig. S7). See focal length; Lagrange's law; law of refraction; Newton's formula; fundamental paraxial equation.
Dalrymple's sign Retraction of the eyelids causing an abnormally widened palpebral fissure, in primary gaze. This is a sign of Graves' disease. The patient appears to stare and to be frightened as some white sclera may be seen above the upper limbus.
doll's eye sign See doll's head phenomenon.
von Graefe's sign Immobility or lagging of the upper eyelid when looking downward. This is a sign of Graves' disease.
Gunn's crossing sign Tapering of veins on either side of the arteriovenous crossings seen in hypertensive retinopathy.
Hutchinson's sign A triad of signs present in congenital syphilis. They are interstitial keratitis, notched teeth and deafness.
local sign See oculocentric direction.
Moebius' sign Convergence weakness occurring in Graves' disease.
Mizuo's sign See Mizuo's phenomenon.
Munson's sign A sign observed in keratoconus in which the lower lid is bulging as a cone when the patient looks downward.
pseudo-von Graefe sign See aberrant regeneration.
Rizzuti's sign An arrowhead pattern near the nasal part of the corneoscleral limbus, sometimes seen in advanced keratoconus.
Salus' sign Retinal vein deflection from its normal course at arteriovenous crossings seen in hypertensive retinopathy.
Seidel's sign See Seidel's scotoma.
Shafer's sign The presence of pigment granules of various sizes floating in the anterior vitreous. They usually result from a retinal break/s, which may progress into rhegmatogenous retinal detachment. Then the pigment cells appear as small black dust-like particles ('tobacco dust') seen on clinical examination.
Vogt's sign Loss of the normal shagreen of the front surface of the crystalline lens indicating anterior capsular cataract. See crocodile shagreen.
Uhthoff's sign See Uhthoff's symptom.

The diagnostic difficulty is not that conversion symptoms suggest neurological disease, but that symptoms of neurological disease are often misdiagnosed as CD; thus the differential diagnosis is very important and can be tricky.
From a strictly anatomical standpoint, conversion symptoms fail to respond to known patterns of nerve distribution or function.
This is supported by the fact that when unilateral, conversion symptoms are more frequently manifested on the left side of the body versus the right side.[2,3,10,16]
Due to findings such as these, many clinicians now feel that conversion symptoms that present as paresthesias on the left side of the body should be assumed to be neuropathologic despite paresthesias which may not correlate with normal neuroanatomical boundaries; these may be underlying neurophysiological changes in process.
This explanation stands in contrast to that offered in relation to the development of conversion symptoms, in which psychic stimulation occurring as a result of internal conflict is repressed and after being ejected from the mind is expressed as an organic symptom (Freud, 1894).
The genesis of somatic symptoms is also not linked to particular causal trauma as is the case with conversion symptoms. It is likely that this is because the origin of somatic symptoms is now understood to be a sustained, continuous set of experiences that result in arrested emotional development (Fonagy, Gergley, Jurist and Target, 2004; Mitrani, 1993).
It would thus seem that conversion symptoms demonstrate a problem in the preconscious layer of thought, or at Luquet's metaprimary or metaconscious and intuitive layers of thought (Bouchard and Lecours, 2004).
Psychic energy blocked by repressed and unfulfilled desires gains expression in various physical channels resulting in conversion symptoms. With the appearance of physical symptoms, the anxiety produced by unconscious and unacceptable wishes is expressed symbolically and is, therefore, reduced.
Conversion symptoms do not merely function as a way of relieving anxiety, rather, as an escape from the social consequences of being in a conflicting situation.
Eigen values and screen plot identified four meaningful factors: conversion symptoms, physical pain symptoms, hypochondriacal symptoms, and body dysmorphic symptoms.
