This study compares formal and informal caregivers' perceptions of delusions and hallucinations in older persons with dementia (PWDs). The study population consisted of 151 community-dwelling PWDs aged 65 and older, 90 formal caregivers, and 151 informal caregivers residing in Israel. Assessments included the Behavioral Pathology in Alzheimer's Disease Rating Scale, Neuropsychiatric Inventory, Etiological Assessment of Psychotic Symptoms in Dementia, Activities of Daily Living, and Mini-Mental State Examination. Informal caregivers reported higher rates and a higher level of severity of delusions and hallucinations than formal caregivers. Different caregivers showed varying degrees of emotional involvement, empathy, and efforts to find the meaning of the delusion for the person experiencing it. Family members and staff members may see different parts of the total picture. The combination of both points of view is essential in order to establish an accurate, comprehensive assessment of dementia symptoms and to enhance the understanding of the reality of the different parties.

Objectives: There has been limited exploration into the nature and development of psychotic experiences (PEs) in Parkinson's disease (PD). We aimed to comprehensively assess the frequency, severity, and associated distress of paranoia and unusual sensory experiences (USEs) in PD, and to assess what variables are significantly associated with these experiences, focussing on psychological processes central to understanding PEs in non-PD groups.
Method: A questionnaire battery was completed by 369 individuals with PD with a mean age of 66 years and mean time since diagnosis of 5 years.

Aims: Clinical high-risk for psychosis (CHR-P) states exhibit diverse clinical presentations, prompting a shift towards broader outcome assessments beyond psychosis manifestation. To elucidate more uniform clinical profiles and their trajectories, we investigated CHR-P profiles in a community sample.
Methods: Participants ( = 829; baseline age: 16-40 years) comprised individuals from a Swiss community sample who were followed up over roughly 3 years.

Schizophrenia (SZ), a complex psychiatric disorder of neurodevelopment, is characterised by a range of symptoms, including hallucinations, delusions, social isolation and cognitive deterioration. One of the hypotheses that underlie SZ is related to inflammatory events which could be partly responsible for symptoms. However, it is unknown how inflammatory molecules can contribute to cognitive decline in SZ.

Research has shown that heightened emotionality often precedes psychotic experiences. Understanding how individuals cope with these emotions is crucial for psychosis. While prior studies on emotion regulation (ER) and psychosis have mainly relied on self-report questionnaires, recent research has increasingly utilised daily life methods.
