The literature on hallucinations is reviewed, including its occurrence in different psychiatric disorders, neurological disorders and normal persons. The diagnostic significance of hallucinations is also discussed. Reports of hallucinations in normal people are reviewed. The different modes of the management of hallucinations are briefly discussed.

Inhibitory deterioration may contribute to hallucinations in Alzheimer's disease

“…As predicted, AD participants showed more delusions, hallucinations, anxiety, depression and executive dysfunction than older adults. These results are in line with the literature showing high prevalence of delusions and hallucinations in AD, suggesting these clinical manifestations to be a critical sign of psychotic manifestations in the disease (Bassiony & Lyketsos, 2003;Chaudhury, 2010). Our findings also fit with the literature suggesting high prevalence of anxiety and depression in AD (Bierman et al, 2009;Holtzer et al, 2005).…”

“…The literature suggests a relationship between confabulations and executive dysfunction in individuals with AD (Dalla Barba et al, 1999). Further, the literature also indicates a possible relationship between delusions-hallucinations and depression and anxiety in a wide variety of neurological and psychiatric diseases (Birchwood & Chadwick, 1997;Chaudhury, 2010). In the context of the present study, it was therefore hypothesised that the same pattern would also be present in individuals with AD.…”

“…Individuals with severe depression commonly report auditory hallucinations, which are generally transient and limited to single words or short phrases and, usually, communicating thoughts consistent with the patient's depressed mood (Chaudhury, 2010). In accordance with this assumption, depression and anxiety have been found to be common in individuals with hallucinations (Birchwood & Chadwick, 1997).…”

Validation of a Psycho-Sensory hAllucinations Scale (PSAS) in schizophrenia and Parkinson's disease

“…negative aspects of visual hallucinations). Moreover, it allows us to assess the importance of not only diagnosis of the 'basic' disorder but also to deal with the patient's conviction, especially regarding the psychological treatment of hallucination in refractory hallucinations (Chaudhury, 2010). The PSAS may be used to assess an individual's level of hallucinations which is likely to be an important addition in both clinical and research contexts.…”

Online Gaming Behavior And Psychosocial Well-Being In Greek Adolescents

“…Also, somatic complaints in problematic and even at-risk users could derive from spending prolonged hours on the computer screen and as a result having eye problems, dizziness, headaches and sleep disturbances (Dreier et al, 2013). Moreover, somatic complaints may have given rise to the thought problems scale since sleep deprivation, due to excessive engagement in online gaming during the late evening hours, is related to hallucinations http: //dx.doi.org/ 10.15405/ejsbs.180 eISSN: 2301-2218 / Corresponding Author:Elisavet Pappa Selection andpeer-review under (Chaudhury, 2010). Also, thought problems could stem from the obsessive-compulsive symptoms found in several addictions as well as in gaming addiction (Jang, Hwang & Choi, 2008).…”
