The purpose of this study was to assess if a relationship exists between the nature of an individuals criminal charges and the finding of fitness among defendants evaluated at the Forensic Psychiatry Clinic servicing Manhattan. We examined the records of 354 defendants referred to the Forensic Clinic from the New York Criminal and Supreme Courts for a competency to stand trial evaluation. We reviewed their charges in light of the finding of competency. Incompetent defendants were most often accused of misdemeanors rather than felonies and of non-violent rather than violent crimes. Perhaps individuals who are thought to be psychiatrically disturbed get detained by the police on trivial charges so as to get them off the streets. Deinstitutionalization and civil commitment laws are considered as contributing factors and their impact is discussed

The United States Supreme Court, in the recent case of Riggins v. Nevada, extended its examination of the issue of involuntary treatment with anti-psychotic medication to the mentally disabled facing criminal trial. Although this was an extreme case where the defendant faced a possible death sentence, the involuntary administration of anti-psychotic medication to restore 'competency to stand trial' always raises unique medical and moral questions. This highly controversial issue has received little empirical investigation. We report here on the first study to follow-up on the disposition of the criminal charges of persons committed to a hospital for the restoration of 'competency to stand trial' who refused anti-psychotic medication and for whom involuntary treatment was sought. We have previously reported on the characteristics of these cases (N = 68) and aspects of their outcome in the hospital. This cohort of patients represents virtually all indicted felony offenders in New York state who were incompetent to stand trial and for whom involuntary treatment with anti-psychotic medication was requested between 1986 and 1990. The present retrospective report focuses on the disposition of the criminal charges for such cases, in a state that does not have a death penalty. Tentative inferences are considered based on the findings that persons who were involuntarily restored to 'competency to stand trial' had a variety of dispositions of their criminal charges, including plea negotiations that resulted in foreshortened incarceration and several cases of insanity acquittals. Suggestions for further and more conclusive studies are proposed

PURPOSE: To test the hypothesis that atrophy of the hippocampal formation in nondemented elderly individuals would predict subsequent Alzheimer disease. METHOD: We studied 86 subjects at two time points, 4 years apart. At baseline all study subjects were nondemented and included 54 control subjects and 32 persons who had memory complaints and minimal cognitive impairments. All subjects received a CT scan using a protocol designed to image the perihippocampal cerebrospinal fluid (HCSF) accumulating in the fissures along the axis of the hippocampal formation. Blind to the clinical evaluations, we subjectively assessed the presence of HCSF at the baseline. Retrospectively, we examined the predicted association between baseline HCSF and clinical decline as determined across the two evaluations. RESULTS: At follow-up 25 of the 86 subjects had deteriorated and received the diagnosis of Alzheimer disease. Of the declining subjects, 23 came from the minimally impaired group, and 2 came from the control group. In the minimally impaired group the baseline HCSF measure had a sensitivity of 91% and a specificity of 89% as a predictor of decline. Both control subjects who deteriorated were also correctly identified at baseline. One of these two subjects died, and an autopsy confirmed the presence of Alzheimer disease. M(r) validation studies demonstrated that HCSF is quantitatively related to dilatation of the transverse fissure of Bichat and the choroidal and hippocampal fissures. CONCLUSION: Our findings strongly suggest that among persons with mild memory impairments, dilatation of the perihippocampal fissures is a useful radiologic marker for identifying the early features of Alzheimer disease

We evaluated three groups of elderly individuals who were carefully screened to rule out clinically significant diseases that could affect cognition. They were matched for age and education. The groups included normals (N = 18), Alzheimer's Disease (AD) patients (N = 15), and minimally impaired individuals with memory complaints and impairments but who did not fulfill criteria for AD (N = 17). Volumetric measurements of different regions of the temporal lobe on the coronal scan as well as ratings of the perihippocampal cerebrospinal fluid (CSF) accumulation (HCSF) on the negative angle axial MR were carried out. Volume reductions were found in AD relative to the normals for both medial and lateral temporal lobe volumes. Only hippocampal volume reductions were found in the minimal group. The minimally impaired individuals had equivalent hippocampal volume reductions and significantly larger parahippocampal and lateral temporal lobe gyri than the AD group. The axial HCSF was validated using the coronal volumes. The combination of coronal hippocampal and perihippocampal CSF was the best predictor of the axial HCSF rating. The parahippocampal volume did not add to the predictive ability of the hippocampal-perihippocampal CSF combination. Future work should validate these findings with longitudinal designs as well as assess the issue of normal aging of these structures and their relationship to cognitive function

Post-mortem MRI (magnetic resonance images) studies followed by histopathological examination were used to study the size and the shape of the lateral part of the transverse fissure of the brain in seven individuals with Alzheimer disease (AD) and five controls. In control brains, the lateral part of the transverse fissure is a narrow cleft protruding laterally as choroid and hippocampal recesses. In AD-affected brains, the lateral part of the transverse fissure becomes a large subarachnoid space as a result of different degrees of atrophy of various hippocampal and parahippocampal structures. Our findings directly indicate the relationship between changes in the hippocampal and parahippocampal structures and the size of the lateral part of the transverse fissure. Sector CA1, the subiculum, the entorhinal cortex, and the parahippocampal isocortex are the most affected, whereas the dentate gyrus is much less affected. Adjacent thalamic structures, which are less vulnerable to the AD pathology, do not appear to contribute to transverse fissure changes. The size and the shape of the lateral part of the transverse fissure of the brain in AD reflect the atrophy of the hippocampus and parahippocampal structures

The United States Supreme Court, in the recent case of Riggins v. Nevada, extended its examination of the issue of involuntary treatment with antipsychotic medication to the mentally disabled facing criminal trial. A criminal defendant who is "incompetent to stand trial" cannot be subjected to trial. Many such persons are committed to hospitals to be treated and rendered "competent to stand trial," and some of these patients refuse medication. The involuntary administration of antipsychotic medication to such patients raises important and unique medical and moral questions. This highly controversial issue has been understudied. We report here on the first study of persons committed to a state hospital in order to be rendered competent to stand trial who refuse antipsychotic medication and for whom judicial review is requested to allow involuntary treatment, and in which results are given specifically for these subjects. This is a retrospective study to determine the characteristics of such cases and aspects of their outcome in the hospital. We reviewed all cases (N = 68) of application for treatment over objection, filed since the inception in 1986 of the new laws and regulations requiring judicial review through 1990, among patients in the two facilities that receive over 95 percent of all indicted felony offenders in New York State who are incompetent to stand trial. Tentative conclusions are formulated based on the findings that, according to clinical reports, no patient gave only rational reasons for medication refusal, clinicians always indicated the clinical appropriateness of the proposed treatment, judges apparently never found that someone who is "incompetent to stand trial" is "competent" to refuse medication, 93 percent of patients treated involuntarily had a good clinical response, and 87 percent of patients treated involuntarily were restored to "competency to stand trial."

This paper presents the results of a retrospective analysis of the discharge summaries of 69 mentally ill offenders. The subjects were patients in a New York State Psychiatric Hospital for a two-year period between January 1988 and December 1989 who were referred by the courts under New York State Criminal Procedure Law (CPL). The subjects were further compared as to homelessness at the time of the instant offense to study the association of this variable and criminal behavior among the mentally ill. Statistical analyses demonstrated significant relationships between variables of homelessness, prior offense history, and substance abuse

A 13-item questionnaire was constructed to assess risk factors for HIV infection among 476 patients newly admitted over a one-year period to a state psychiatric hospital in New York City. Because psychopathology can affect patients' self-reports, the validity of the instrument was established by HIV antibody tests in a subset of 352 patients. Results of the questionnaire indicated that the 352 patients were almost equally divided between the high-risk and low-risk categories. HIV seroprevalence was .6 percent among the low-risk patients, but 14.4 percent among the high-risk patients. The findings suggest that a screening program to detect HIV-positive patients should be undertaken in this population, that it should be focused on the high-risk subgroup, and that the questionnaire can be used to define that subgroup. However, results of the study may not generalize to other geographic areas
