Neuropsychological and functional correlates of clock-drawing test in elderly institutionalized patients with schizophrenia.

BACKGROUND: There has been a growing need for a cognitive assessment tool that can be used for older adults with schizophrenia in clinical settings. The clock-drawing test (CDT) is a brief cognitive test that covers a wide range of cognitive function. Although it is widely used to assess patients with dementia, limited data are available on its usefulness in older patients with schizophrenia. Thus, we investigated the psychometric properties of the CDT and their relationship with life functions to examine the test's usefulness for assessing cognitive function in older adults with schizophrenia. METHODS: Seventy-three older adults with chronic schizophrenia who had been hospitalized for over 1 year participated in the study. We adopted the executive clock-drawing task for administration and scoring of the CDT, which consists of free-drawn and copy conditions. The Mini-Mental State Examination and the Brief Assessment of Cognition in Schizophrenia were administered. Symptom severity and life functions were assessed with the Positive and Negative Syndrome Scale and the Life Skills Profile, respectively. RESULTS: Both free-drawn and copy scores significantly correlated with the Mini-Mental State Examination score and the Brief Assessment of Cognition in Schizophrenia composite score. These scores also significantly correlated with symptom severity and length of current hospitalization. Stepwise regression analysis showed that only the copy score, together with symptom severity, predicted the Life Skills Profile score. CONCLUSIONS: The CDT can assess cognitive function in older adults with schizophrenia. Moreover, CDT performance is associated with life functions independent from other clinical variables. These results suggest that the CDT is a useful cognitive assessment tool for this population.

[Addictive behavior disorders].

"Addiction" used to remind anyone of the use or abuse of chemical substances. In recent years, however, researchers and clinicians have begun to classify other excessive behaviors including gambling, eating shopping and self-injury into the addictive behavior. Above all, pathological gambling and bulimia nervosa patients often make trouble for psychiatrists and psychologists, not only for their family. On the other hand, the neural substrata underlying substance dependence have been revealed. Especially, it is implicated that the mesolimbic neuron plays a crucial role on the reward system. The recent studies suggest that reduced activation of the reward system might be related to the addictive behaviors such as pathological gambling, binge eating and sexual behavior. Further biological researches about the addictive behavior would help our deeper understanding of its disorders. As to the pharmacotherapy, many studies have demonstrated the efficacy of selective serotonin reuptake inhibitors (SSRIs) in treating the addictive behaviors.

[Diagnosis, assessment, and treatment of alcohol withdrawal syndrome].

Alcohol withdrawal syndrome is the one of the most critical status among alcohol related disorders. Early detection, diagnosis, and appropriate treatment of alcohol withdrawal syndrome are keys to a successful outcome. This article describes the concrete method of diagnosis, assessment, and treatment of alcohol withdrawal syndrome.

[Case report of pentazocine dependence from a standpoint of the cognitive therapy].

Drug dependence is a social problem of over the world and resistant to medical intervention by psychiatrist as well as general clinicians. In Japan, methamphetamine dependence is one of the most critical social problems, but opioid dependence is relatively rare. Pentazocine was called the non-addictive opioid at the time of development and release and there are few reports of its dependence. We experienced a medical worker with pentazocine dependence. He started to use pentazocine to reduce serious migraine and felled into dependence by changing the purpose to relaxation of stammering fear and strain towards other people. He was successfully treated by cognitive therapy.

[Change in body image of patients with alcohol dependence during treatment process].

In order to find useful information for the establishment of new treatment method to alcohol dependence, we investigated the change of the body image of patients with alcohol dependence before and after the treatment. HABIT (Haga Body Image Test), a questionnaire about body image developed in department of psychiatry in Kyoto Prefectural University of Medicine, was used to examine the change of body image between pre- and post-3-month conventional treatment program in 46 patients with alcohol dependence hospitalized into special institutions for treatment of the disease in Kyoto. Patients with poor outcome of the treatment showed improvement of body image on visceral function, feeling of appetite and outward appearance, while patients with good outcome indicated no significant change in these aspects. This finding likely suggests that the treatment would result in good outcome in patients having stable feeling of physical health, and the cognitive treatment approach about these aspects of body image should be performed on the patients with poor treatment outcome. On the other hand, the body image about motor function showed significantly higher score in the patients approach for the patients with poor outcome to become aware of their physical activity would be effective.
