We report 2 children with a history of epilepsy in whom valproic acid (VPA) withdrawal was identified as a potential cause of hallucinations. After a restart of VPA, the hallucinations disappeared. We suggest mechanisms for the occurrence of the hallucinations and a possible control of a predisposition to hallucinations by VPA.

Auditory hallucinations are important symptoms when making a diagnosis of schizophrenia. Since normal people may also experience auditory hallucinations, there may be a spectrum of auditory hallucinations ranging from those experienced in schizophrenia to those experienced by normal people. To assess the propensity to auditory hallucinations in a non-clinical population, we selected forty items...

The study of voice-hallucinations in deaf individuals, who exploit the visuomotor rather than auditory modality for communication, provides rare insight into the relationship between sensory experience and how "voices" are perceived. Relatively little is known about the perceptual characteristics of voice-hallucinations in congenitally deaf people who use lip-reading or sign language as their p...

BACKGROUND Auditory hallucinations are experienced by 60-80% of all patients diagnosed with a schizophrenia spectrum disorder. However, in this patient group, the prevalence of hallucinations in multiple sensory modalities, i.e. multimodal hallucinations (MMHs), is unknown. AIMS To assess the prevalence of MMHs in patients diagnosed with a schizophrenia spectrum disorder, data were analyzed f...

OBJECTIVES The Model of Functional Deficits associated with hallucinations is used as part of the clinical documentation in the San Jose State University Psychosocial Occupational Therapy Clinic. On the basis of this model, hallucinations are classified according to functional deficits and whether the deficits are a result of the content or intrusiveness of the hallucinations. This classificati...

The study objective was to evaluate changes in prevalence of command hallucinations to harm self or others, characteristics and intensity of auditory hallucinations, and levels of anxiety and depression after attendance at a 10-session course teaching behavioral strategies for managing persistent auditory hallucinations to adult outpatients with schizophrenia. Prevalence of command hallucinatio...

Hallucinations are perceptual disorders in which the patient expresses something that is not actually happening. As a result of untreated hallucinations, unwanted things can also appear, such as hallucinations instruct to do kill himself or injure others. One treatments for sensory perception disorder patients: auditory by means occupational therapy (drawing). The general objective this scienti...

Lilliputian hallucinations are infrequent but reported in a variety of states ranging from toxic metabolic states, medical, neurological and psychiatric conditions. We report three cases with different psychiatric diagnoses all presenting with vivid Lilliputian hallucinations. An attempt to apply the current biological mechanisms that explain complex visual hallucinations to Lilliputian halluci...

Charles Bonnet Syndrome (CBS) is a common cause of visual hallucinations seen in elderly people with visual impairment. Well-formed visual hallucinations in clear consciousness with preserved insight are commonly reported in literature. We report a case of CBS having multisensory hallucinations. An elderly patient with visual impairment fulfilling the criteria of CBS presents with various modal...

Hallucinations remain problematic in Parkinson's disease (PD). Various factors have been studied, and many previous studies identified risk factors for hallucinations, such as sleep disorders. At the same time, fatigue is a common symptom in Parkinson's disease, and any factors associated with fatigue in PD have been reported. Factors associated with fatigue in PD are likely to be similar to ri...
