RESUMO

The Excited Delirium Syndrome (ExDS) is a state of maximum psychophysiological excitation far beyond mental agitation. Patients themselves are at an acute risk and put others at a high risk. We present data from eleven patients and a short literature review. Results: 9 of 11 patients were acutely intoxicated (alcohol, magic mushrooms, THC, ecstacy, or "flakka"). Eight had a history of substance abuse and 4 of other mental illness. None of the patients responded to attempts at verbal de-escalation. Seven had significant injuries at the time of admission to the hospital. The aggressive "psychiatric" presentation of ExDS can lead to vital risks being overlooked (hyperexcitation, acidosis, rhabdomyolysis, hypoxemia, and cardiovascular decompensation), which may even be increased by severe methods of restraint (hogtie; positional asphyxia). Early recognition of ExDS and its risks, comprehensive management and the prevention of inappropriate treatment will help to reduce fatal outcomes.

RESUMO

Many elderly patients suffer from both, depressive symptoms and cognitive deficits. Clinically, it oftentimes appears unclear whether the affective or the cognitive problems are primary or secondary. Modern molecular and imaging markers contribute to a more efficient distinction between depression and incipient dementia due to neurodegenerative, vascular, and other diseases. A careful history and clinical investigations are necessary to identify the underlying diseases, but they do not always offer sufficient therapeutic guidance. If in doubt, the condition should always be considered as potentially reversible and treated emphatically (but with age-appropriate caution).

RESUMO

Psychiatric disorders are ubiquitously characterized by debilitating social impairments. These difficulties are thought to emerge from aberrant social inference. In order to elucidate the underlying computational mechanisms, patients diagnosed with major depressive disorder (N = 29), schizophrenia (N = 31), and borderline personality disorder (N = 31) as well as healthy controls (N = 34) performed a probabilistic reward learning task in which participants could learn from social and non-social information. Patients with schizophrenia and borderline personality disorder performed more poorly on the task than healthy controls and patients with major depressive disorder. Broken down by domain, borderline personality disorder patients performed better in the social compared to the non-social domain. In contrast, controls and major depressive disorder patients showed the opposite pattern and schizophrenia patients showed no difference between domains. In effect, borderline personality disorder patients gave up a possible overall performance advantage by concentrating their learning in the social at the expense of the non-social domain. We used computational modeling to assess learning and decision-making parameters estimated for each participant from their behavior. This enabled additional insights into the underlying learning and decision-making mechanisms. Patients with borderline personality disorder showed slower learning from social and non-social information and an exaggerated sensitivity to changes in environmental volatility, both in the non-social and the social domain, but more so in the latter. Regarding decision-making the modeling revealed that compared to controls and major depression patients, patients with borderline personality disorder and schizophrenia showed a stronger reliance on social relative to non-social information when making choices. Depressed patients did not differ significantly from controls in this respect. Overall, our results are consistent with the notion of a general interpersonal hypersensitivity in borderline personality disorder and schizophrenia based on a shared computational mechanism characterized by an over-reliance on beliefs about others in making decisions and by an exaggerated need to make sense of others during learning specifically in borderline personality disorder.

RESUMO

OBJECTIVE:  This study examines the impact of the COVID-19 pandemic and the lock-down on patients with mental illness. METHODS:  Patients in inpatient or outpatient psychiatric treatment received a questionnaire, examining psychological distress and psychiatric care during the COVID-19 pandemic. RESULTS:  More than half of the patients indicated that the state of emergency had a negative impact on their mental illness. Severely ill patients were more affected. CONCLUSION:  Patients with mental illness are a particularly vulnerable group in the current crisis. Psychiatric and psychotherapeutic care needs to be adapted accordingly; the specific burden and distress needs to be examined actively in patients from all diagnostic groups.
