A total of 154 patients admitted for the first time to hospital for a psychotic or affective disorder in 1925 were rediagnosed in accordance with DSM-III and Leonhard's diagnostic system. Symptoms were rated in accordance with a rating protocol containing 33 items based on Leonhard's descriptions of cycloid psychoses. The patients were followed up through parish registers and hospital records. Of 42 cases considered to be cycloid psychosis at index admission, 34 were prognostically verified. The symptom ratings of the 154 patients were analysed by K-means cluster analysis to test whether the patients with cycloid psychoses would separate from the rest of the material. With a 2-cluster solution, 30 of 34 cases (88%) were contained in the same cluster. The sensitivity of the ratings was therefore judged to be acceptable. Specificity was low, however, since 19 cases in the cluster were differently diagnosed. A subcohort of 64 patients, satisfying at least 5 items of the rating protocol, was then analysed by Q-factor analysis to test whether nuclear cases of cycloid psychosis differ from symptomatically related syndromes. No such differences could be statistically verified; no symptom profile specifically indicating cycloid psychosis could be found. Prominent confusion symptoms appear, however, to be prognostically favourable, whereas motility symptoms without confusion seem to indicate an unfavourable course.

All incident cases of clinically diagnosed Alzheimer's disease were identified through the unique record linkage system of the Mayo Clinic. Thirty-nine (32%) of the sample of 122 had a psychiatric history that preceded the onset of CDAD by at least 3 years. Twenty-five percent of the study population had had an episode of delirium within 2 years of the onset of CDAD. Eighty-four percent of the cases had psychiatric symptoms in the course of CDAD that were documented in their medical records. Specific symptom patterns included agitation, combativeness, confusion and disorientation, depression, psychosis, and wandering. These symptoms occurred more frequently in clusters than singularly.

1. Patients with post-traumatic stress disorder (PTSD) often encounter treatment that is complicated by professional bias, personal issues, countertransference, and pathological staff dynamics. 2. Treatment is further complicated by diagnostic confusion, the dual diagnoses of substance abuse or depression, and symptoms that mimic personality disorders or psychosis. 3. The special circumstances of the Vietnam conflict that contributed to the susceptibility and etiology of PTSD are the individual characteristics of those who served, the special nature of the war itself and the military strategies used, and the psychosocial and cultural milieu in which it occurred.

The prevalence of psychotic complications of levodopa treatment was assessed in 198 Parkinson patients. The symptoms were seen in 44 (22.2%). Those who developed complications were significantly older at disease onset (63.3 +/- 9.2 vs 57.6 +/- 11.6). The observed psychiatric symptoms were classified into two categories: simple, including incidents of confusion alone or hallucinations with preserved insight, and complex, including delusions or chronic confusion without preserved insight. Patients with complex symptoms were significantly younger at the onset of the disease, and the duration of the disease prior to these psychiatric symptoms was longer than in the group of patients with simple symptomatology. Patients with complex symptoms were more susceptible to another central side-effect of the treatment: dyskinesias, than those with simple.

In a double-blind placebo-controlled study, we evaluated the effects of clozapine (75 to 250 mg/day, mean 170.8) on dopaminomimetic psychosis and parkinsonian disability. Clozapine prevented deterioration of psychosis during the increase of dopaminomimetics in the 3 patients who completed the study. Worsening of parkinsonism occurred in 3 of the 6 patients. In the dosage used, clozapine's usefulness was limited by its propensity to produce sedation, confusion, and increased parkinsonism.

Postanesthetic delirium is a type of postoperative emotional response occurring immediately after emergence from general anesthesia. Associated with excitement and confusion, the alternative terms emergence delirium or postanesthetic excitement are frequently used. Historically, the more encompassing term postoperative psychosis is used interchangeably but more frequently refers to those conditions occurring after a lucid interval of 24 to 48 hours. Either phenomenon may arise from a variety of disturbances, with drug reactions, hypoxemia, or reaction to pain being common, or it may arise from psychological causes. Reported is a case of postanesthetic delirium in a healthy young man. An historical overview of this potentially harmful condition, with specific recommendations for diagnosis and treatment, also is presented.

Dysmorphophobia is a controversial term. It is not a phobia, reliable data on it are few, and many authors write about it without attempting to define it. DSM-III-R introduced the term "body dysmorphic disorder" to describe a non-psychotic condition in which there is pathological preoccupation with physical appearance and with the intention of replacing the term "dysmorphophobia". However, psychiatrists continue to use the word dysmorphophobia, often unaware that it may have several distinct meanings. This article, 1. demonstrates the current confusion in terminology, 2. elaborates on DSM-III-R's concept of body dysmorphic disorder, and 3. suggests refinements for the DSM-IV description.

We performed a prospective, naturalistic study using standardized clinical rating scales to characterize the effect of electroconvulsive therapy (ECT) on mood, cognition, and medical status in late-life depression. Over a 16-month period, 40 patients aged 60 years and over who fulfilled DSM-III criteria for a major depressive episode received a total of 42 ECT courses. Three patients (7%) developed significant medical complications: one had a syncopal episode due to arrhythmia, and two had symptomatic vertebral compression fractures. Confusion was noted during 13 courses (31%) and persisted at discharge in four (10%). More than half the patients were either psychotic or demented on admission, and all but three had been either unresponsive or intolerant to pharmacotherapy. All patients experienced a decrease in their depressive symptoms and more than two thirds were in complete or partial remission at discharge. Patients with psychotic depression experienced a greater improvement than patients with nonpsychotic depression, and patients with organic mental disorders experienced the same improvement as other patients. This study confirms that ECT is a safe and effective treatment of depression in late life.

In a prospective 4-year follow-up study, 26 out of 31 patients initially diagnosed as cycloid psychoses were investigated (anxiety-happiness psychosis n = 15; confusion psychosis n = 8; motility psychosis n = 3). Patients were independently interviewed by two clinical researchers. 61.5% showed one or several 'first-rank symptoms' according to Schneider. In addition, the SADS-LA was applied for RDC and DSM-IIIR diagnoses. According to these classification systems most of the patients were diagnosed as schizophrenic or schizoaffective. Personal interview as well as application of the Strauss-Carpenter Outcome Scale indicated a highly favorable clinical outcome, i.e. lack of affective or behavioral defective states in literally all patients of the study. These results justify the distinction of the cycloid psychoses as a nosological entity in general and--less convincingly--of the three subtypes of cycloid psychoses.

A patient with AIDS developed the Capgras' syndrome as part of an acute confusional state resulting from an opportunistic infection. Neuropsychological testing suggested non-dominant hemisphere dysfunction with impaired facial recognition. Serial CT scanning showed a right parietal lesion which resolved after the psychosis improved. These findings provide further evidence for the hypothesis that selective visuospatial deficits underlie the development of Capgras' syndrome.
