What everyone who studies hallucinations agrees on is that schizophrenic patients misperceive signals generated inside the brain.
Most studies failed to correlate Lewy body density with disease duration, early onset, different symptoms at onset, presence or absence of cognitive fluctuations, visual hallucinations, delusions, recurrent falls, severity of parkinsonism or cognitive decline [ 43– 45, 94, 144].
Recently, however, a small group of scientists has begun studying auditory hallucinations more intensively.
The most common hallucinations are auditory: the patient hears (nonexistent) voices and believes in their reality.
Most are hallucinations". In a startup, you don't fight the system; you are the system.
One study found that the most common visual hallucinations included fully formed adults or children (84%), animals or insects (37%), and objects (39%) [ 27].
Interestingly, in most subjects these hallucinations coincided with the observed period of a maximal increase in cortical excitability on day 1 and day 2 [45] and generally subsided over the course of the study.
Most hallucinations are disorienting and cause distress in those experiencing them, but some can seem pleasant or enjoyable.
For more than a half-century, auditory hallucinations have primarily been studied and discussed in terms of severe mental illness, most notably schizophrenia, and linked to bizarre delusions, disordered thought and emotional dissociation.
Clearly, this issue requires further study, as fantasy proneness has not routinely been measured in nonclinical studies of hallucinations.
