Background: Research and practice typically focus upon unimodal hallucinations, especially auditory verbal hallucinations. Contemporary research has however indicated that voice-hearing may co-occur within a broader milieu of feelings, and multimodal hallucinations may be more common than previously thought.

Methods: An observational design asked participants to prospectively document the feeling and modality of hallucinations for one week prior to an interview. Novel visual diary methods involving drawing, writing and body-mapping generated 42 MUSE maps (multimodal unusual sensory experience), analysed with a participatory qualitative method. Twelve people took part: all experiencing hallucinations daily, accessing early intervention in psychosis services, given psychotic-spectrum diagnoses, and living in the community. The study took place during a seven-month period in 2018 at Leicestershire and Rutland's Psychosis Intervention and Early Recovery service (UK).

Findings: All documented hallucinations co-occurred with bodily feelings. Feelings were localised to specific body areas, generalised across the body and extended beyond the body into peripersonal space. Co-occurring emotional feelings most commonly related to confusion, fear and frustration.

Interpretation: Hallucinations were characterised by numerous feelings arising at once, often including multimodal, emotional, and embodied features. Within this study, the immediate feeling of hallucination experiences were readily communicated through prospective, visual, and ecological information gathering methods and particularly those which offer multiple modes of communication (e.g. body-map, visual, written, oral). Uptake of visual, ecological and prospective methods may enhance understandings of lived experiences of hallucinations. University of Leicester.

ChatGPT's Attitude, Knowledge, and Clinical Application in Geriatrics Practice and Education: Exploratory Observational Study.

JMIR Form Res

January 2025

Minneapolis VA Health Care System, Minneapolis, MN, United States.

Background: The increasing use of ChatGPT in clinical practice and medical education necessitates the evaluation of its reliability, particularly in geriatrics.

Objective: This study aimed to evaluate ChatGPT's trustworthiness in geriatrics through 3 distinct approaches: evaluating ChatGPT's geriatrics attitude, knowledge, and clinical application with 2 vignettes of geriatric syndromes (polypharmacy and falls).

Methods: We used the validated University of California, Los Angeles, geriatrics attitude and knowledge instruments to evaluate ChatGPT's geriatrics attitude and knowledge and compare its performance with that of medical students, residents, and geriatrics fellows from reported results in the literature.

Inter- and intra-hemispheric lateralization alterations in auditory verbal hallucinations of Schizophrenia: insights from resting-state functional connectivity.

Eur Arch Psychiatry Clin Neurosci

January 2025

Department of Psychiatry, National Clinical Research Center for Mental Disorders, and National Center for Mental Disorders, The Second Xiangya Hospital of Central South University, Changsha, 310016, Hunan, China.

Auditory verbal hallucinations (AVHs) in schizophrenia are hypothesized to involve alterations in hemispheric lateralization, but the specific neural mechanisms remain unclear. This study investigated functional intra- and inter-hemispheric connectivity to identify lateralization patterns unique to AVHs. Resting-state fMRI data were collected from 60 schizophrenia patients with persistent AVHs (p-AVH group), 39 patients without AVHs (n-AVH group), and 59 healthy controls (HC group).

Background: Psychosis (broadly delusions and hallucinations) has a cumulative disease prevalence of around 40% in Alzheimer's disease (AD). The epigenomic, genomic, and neuropathological data provide powerful evidence that AD+P has a distinct neurobiological profile. Here, we used the weighted gene co-expression network analysis (WGCNA) method to investigate DNA methylation associated with AD+P in the dorsolateral prefrontal cortex of 153 post-mortem brain samples.

Alzheimers Dement

Background: Lewy bodies (LBs), characterized by intraneuronal inclusions of misfolded alpha-synuclein (α-syn) protein, are the pathological hallmark of Parkinson's disease (PD) and dementia with Lewy bodies (DLB). Because this protein is phosphorylated at serine-129 in 90% of LBs, its phosphorylation is considered a crucial pathogenic event in LB formation and disease development. Here, we present a unique brain autopsy case of a DLB patient with widespread LBs that were negative for phosphorylated-α-syn, challenging traditional diagnostic criteria.

Background: Dementia with Lewy bodies (DLB) is the second most common form of degenerative dementia in older people. The clinical feature of DLB includes cognitive impairment, visual hallucinations, parkinsonism, and fluctuating attention. Three genes, SNCA (-synuclein), APOE (apolipoprotein E), and GBA (glucosylceramidase), have been convincingly demonstrated to be associated with DLB.
