Patients with Korsakoff syndrome in nursing homes: characteristics, comorbidity, and use of psychotropic drugs.

BACKGROUND: Very limited literature exists on the care and course of patients with Korsakoff syndrome (KS) living in long-term care facilities (LTCFs). Even less literature can be found on the pharmacological treatment of behavioral symptoms of KS. The purpose of the present study was to describe baseline characteristics, comorbidity, and the use of psychotropic drugs in institutionalized patients with KS. METHODS: In this cross-sectional descriptive study, 556 patients were included living in ten specialized care units in Dutch nursing homes. Data were collected by means of a retrospective chart review. RESULTS: The majority of patients were men (75%) and single (78%) with a mean age on admission of 56.7 years (SD 8.9, range 29.8-85.3). Mean length of stay was 6.0 years (SD 5.4, range 0.2-33.3). Sixty-eight percent of patients suffered from at least one somatic disease and 66% from at least one extra psychiatric disorder. One or more psychotropic drugs were prescribed to 71% of patients with a great variation in prescription patterns between the different nursing homes. CONCLUSION: Patients with KS depending on long-term care usually have comorbidity in more than one domain (somatic and psychiatric). The indications for prescribing psychotropic drugs are in many cases unclear and it seems probable that they are often given to manage challenging behavior. Longitudinal studies on the evidence for this prescription behavior and possible alternatives are recommended.

Evolution of Wernicke-Korsakoff syndrome in self-neglecting alcoholics: preliminary results of relation with Wernicke-delirium and diabetes mellitus.

We present a descriptive, retrospective study of initial symptoms, comorbidity, and alcohol withdrawal in 73 alcoholic patients with subsequent Korsakoff syndrome. In 25/73 (35%) of the patients the classic triad of Wernicke's encephalopathy with ocular symptoms, ataxia and confusion, was found. In at least 6/35 (17%) of the initial deliria (95% confidence interval: 10-25%) we observed no other underlying causes, thus excluding other somatic causes, medication, (recent) alcohol withdrawal, or intoxication. We suggest that these deliria may have been representing Wernicke's encephalopathy. A high frequency (15%) of diabetics may reflect a contributing factor of diabetes mellitus in the evolution of the Wernicke-Korsakoff syndrome.

An intervention program for ADHD in patients with substance use disorders: preliminary results of a field trial.

The comorbidity of attention deficit hyperactivity disorder (ADHD) is frequently not well recognized in substance abuse treatment institutions in The Netherlands. As a consequence, patients with substance use disorder (SUD) and ADHD often receive suboptimal treatment. To prevent every treatment center from having to invent its own diagnostic procedure and intervention for ADHD, a national working group was established. This group developed an intervention program for the screening, diagnosis, and treatment of ADHD in patients with SUD. This article describes the development and content of this intervention program. An important part of this development was testing the intervention program in two addiction treatment centers in The Netherlands. Systematic screening of ADHD was part of the test. A self-report questionnaire was used. Subjects with positive screening results were referred for the diagnostic procedure. Nine hundred twenty-eight screenings were performed: 207 screened positive, 115 came for further diagnostics, and 65 were ultimately diagnosed with ADHD.
