[Recommendations for the diagnostic and therapy of behavioural and psychological symptoms of dementia (BPSD)].

The «Recommendations for the Diagnosis and Treatment of Behavioral and Psychological Symptoms of Dementia (BPSD)» were developed in parallel with the Swiss National Dementia Strategy 2014-2019 under the auspices of the Swiss Society for Geriatric Psychiatry and Psychotherapy (SGAP) and mark the beginning of a series of recommendations for geriatric psychiatric disorders. They depict the evidence-based state of knowledge about diagnostics and therapy, based on the clinical experience of the experts, and are designed for interprofessional and interdisciplinary use. The non-pharmacological intervention options and pharmacotherapy are discussed in detail.

Disclosure of Diagnosis in Early Recognition of Psychosis.

There is a debate concerning risks and benefits of early intervention in psychosis, especially concerning diagnosis disclosure. The present study reports preliminary findings on self-reported locus of control and psychological distress after the disclosure of diagnosis in an early recognition center. We compared the ratings of the locus of control and psychological distress before and after communication of diagnosis.

Evaluative Conditioning with Facial Stimuli in Dementia Patients.

We present results of a study investigating evaluative learning in dementia patients with a classic evaluative conditioning paradigm. Picture pairs of three unfamiliar faces with liked, disliked, or neutral faces, that were rated prior to the presentation, were presented 10 times each to a group of dementia patients (N = 15) and healthy controls (N = 14) in random order. Valence ratings of all faces were assessed before and after presentation.

Affective learning and psychophysiological reactivity in dementia patients.

We examined the association of faces with biographical information that varied in emotional content in patients with Alzheimer's disease and a healthy control group. During two experimental sessions, participants rated neutral male faces on dimensions of hedonic valence and emotional arousal, later paired with fictitious biographical information. Both groups changed their ratings of the faces according to the biographical content.

Implicit learning of affective responses in dementia patients: a face-emotion-association paradigm.

The aim of the present study was to develop and evaluate an ecologically valid approach to assess implicit learning of affective responses in dementia patients. We designed a Face-Emotion-Association paradigm (FEA) that allows to quantify the influence of stimuli with positive and negative valence on affective responses. Two pictures of neutral male faces are rated on the dimensions of valence and arousal before and after aversive versus pleasant fictitious biographical information is paired with each of the pictures.

Acquisition of affective dispositions in dementia patients.

In this study, we investigated the acquisition of affective dispositions towards neutral faces in patients with Alzheimer's disease and mixed dementia. Participants viewed four affectively neutral male faces from the International Affective Picture System. Biographical information about the depicted persons was presented, which described them in terms of positive or negative traits varying in intensity.
