Among 100 Chinese psychiatric patients at a general hospital in Singapore, more women than men attributed their illness to spirit possession, but belief in possession was not linked to education. Thirty-six patients or their relatives had consulted a traditional healer before seeking hospital care. The tendency to consult a traditional healer was not associated with illness duration, sex, educational status, or whether the patient was psychotic or neurotic. Most depressed patients (72%) presented with physical symptoms such as chest discomfort, headache, and abdominal discomfort, and this somatization was unrelated to education or sex.

A systematic review of published studies and ongoing clinical trials on nitrous oxide (N2O) for psychiatric disorders identified five published articles, four of which focused on depression. Three randomized controlled trials (RCTs) for treatment-resistant depression and major depressive disorder suggest that N2O has preliminary feasibility with rapid-acting effects on depressive symptoms. Ten ongoing trials are exploring N2O for depression, post-traumatic stress disorder, bipolar disorder, obsessive-compulsive disorder, and suicidal ideation. Typical treatment involves a single session of 50% N2O for 60 minutes, though 25% is also being tested. Larger-scale RCTs with repeated doses and follow-up beyond one month are needed to confirm efficacy and sustainability.

Cannabis-induced psychosis and acute schizophrenia show distinct demographic, premorbid, and clinical features. Among 61 patients (26 with cannabis-induced psychosis, 35 with acute schizophrenia), those with cannabis-induced psychosis were more often male, had more expansive mood and ideation, derealization or depersonalization, visual hallucinations, and sensorium disturbances. Premorbid schizoid personality traits were more common in acute schizophrenia, while antisocial personality traits were more frequent in cannabis-induced psychosis. The findings suggest that continuous heavy cannabis use can induce a psychotic disorder that is separate from acute schizophrenia, with both shared and differing characteristics.

The study examined whether cannabis psychosis shares a consistent pattern of symptoms with schizophrenia and mania. Data from patient case notes showed that age and hospital stay duration were similar across the three groups. While some differences in symptom distribution were found, no consistent symptom pattern unique to cannabis psychosis could be demonstrated.

Over one year, eleven patients hospitalized with psychosis linked to cannabis abuse were studied, excluding those with pre-existing psychosis or mixed substance use. Patients fell into acute, subacute, and chronic groups. All showed similar symptoms: a mix of affective and schizophrenia-like features, confusion, and pronounced aggressiveness. The illness typically resolved on its own without lasting effects, and there was almost no family history of severe mental illness. The symptoms closely resembled cycloid psychosis, and a possible connection between the two is discussed. Despite widespread cannabis use, psychosis is a rare complication, but in unclear psychotic states, actively searching for cannabis psychosis is recommended.

The paper offers a theoretical analysis of the concepts 'disturbed state of consciousness' (DSC) and 'psychosis,' aiming to define them in ways consistent with Continental clinical psychiatric practice. For DSC, two points are emphasized: that classifying a state as pathological involves evaluating the client's ability to change it voluntarily, and that stating a DSC was present during a time interval implies all experiences during that interval were abnormal, in the broad sense including William James' 'fringe' and 'embeddedness.' For psychosis, reality testing remains central, provided a clear distinction is made between theoretical full-blown syndromes and concrete syndromes with fewer symptoms.
