Glossary for Hallucinations

Medical terms related to Hallucinations or mentioned in this section include:

  • Acanthamoeba infection: Infection with a microscopic, free-living ameba that is readily found in the environment - soil, air and water. Most people exposed to the ameba will not become infected but when infections do occur, they tend to affect the eyes, central nervous system or can cause widespread infection throughout the body.
  • Acanthamoeba infection of the central nervous system: Infection by an amoebic organism called Acanthamoeba. Infection usually occurs when the amoeba enters through a break in the skin or through the nose. Infection can be localized or systemic where it can involve the central nervous system and cause potentially fatal meningoencephalitis. Infection of the eye can occur by cleaning contact lenses in contaminated water.
  • Acid-Base Imbalance: A disruption to the normal acid-base equilibrium in the body. There are four main groups of disorder involving an acid-base imbalance: respiratory acidosis or alkalosis and metabolic acidosis or alkalosis. Obviously the severity of symptoms is determined by the degree of imbalance.
  • Acute intermittent porphyria: A rare inherited metabolic disorder caused by a disturbed porphyrin metabolism resulting in increased production of porphyrin or its precursors. Symptoms include abdominal pain, photosensitivity and neurological disturbances such as seizures, coma, hallucinations and respiratory paralysis.

They are often used as a cheap, readily available alternative to street drugs but they can cause serious damage to the body. Adhesives include household glues, rubber cement and model aeroplane glue. These adhesives can be abused by sniffing them, spraying directly into the mouth, heating them and then inhaling them or injecting them directly into the body.
  • Adhesive addiction: Adhesive addiction refers to the compulsive need to abuse adhesives (e.g. sniffing them). Sufferers have withdrawal symptoms when attempting to stop the habit and feel unable to stop the habit despite knowing the harm it is causing their health. Aerosols are very damaging to the body and can readily result permanent brain damage and even death. Death can occur through chronic use and in rare cases can occur after one session of use. Children and teenagers are particular at risk for this type of addiction - it is readily available and users feel it gains them greater acceptance from their peers.

  • Adrenal adenoma, familial: A benign tumor that develops in the adrenal gland and tends to run in families. The tumor may be nonfunctioning (does not produce hormones) or functioning in which case excessive levels of hormones can cause a variety of symptoms depending on which hormone is involved. Adrenal hormones made in the cortex (outer part of the gland) are aldosterone, corticosteroids and androgenic steroids . Adrenalin and noradrenalin are the hormones made in the medulla (central part of the adrenal gland).
  • Adrenal gland hyperfunction: Excessive activity of the adrenal gland which causes excessive production of one or more adrenal hormones (aldosterone, corticosteroids, androgenic steroids, epinephrine and norepinephrine). The increased adrenal gland activity may be caused by an adrenal gland tumor or by excessive stimulation of the gland. Pituitary hormones stimulate adrenal gland activity.
  • Adrenal incidentaloma: A tumor of the adrenal gland that is discovered incidentally while performing an imaging examination for reasons other than an adrenal tumor. The tumor may be asymptomatic or can causes excessive secretion of adrenal hormones and resulting symptoms. The tumor may also be malignant or benign.
