Patients were also assessed for three forms of hallucinations which included; auditory, visual and tactile hallucinations.
Two and 21 persons experienced all or at least two forms of hallucinations respectively.
Consequently, it appears that some specific forms of hallucinations may result from 5HT2AR activation, in addition to other specific clinical abnormalities.
Combined forms of hallucinations (i.e. hallucinations in two or more modalities) were rare in patients with subthreshold hallucinations (1 case), but frequent in patients with definite hallucinations (30%% of cases).
Our results also suggest that combined forms of hallucinations and delusions were almost exclusively present in patients with definite psychotic symptoms and rarely observed in patients with subthreshold manifestations.
It is necessary to articulate these three mechanisms into an integrated model, or, alternatively, there may be different forms of hallucinations, that are mediated by different pharmacological supports and neurobiological circuits.
According to the web, I have "exploding head syndrome" (EHS), a form of hallucination where a person hears a deafening noise, like a bomb exploding, or – in my case – the hideous screams of a family member.
The assessment outcome was no or yes for each form of hallucination and for hallucinations in general if the patient reported experience of any of the three forms.
It is likely that the IFG and auditory cortex are related to the specific form of hallucination that we studied (AVH), whereas other circuitries, whose coupling with the IFG correlated with the SRH, could be involved more generally in reality distortion.
