The Spectrum of Alcohol Use: Epidemiology, Diagnosis, and Treatment.

In the United States, alcohol is the most common substance used and the spectrum of unhealthy alcohol use is highly prevalent. Complications of unhealthy alcohol use affect nearly every organ system. One of the most frequent and potentially life-threatening of these complications is alcohol withdrawal syndrome for which benzodiazepines remain first-line therapy. Pharmacologic treatment of alcohol use disorder, the most severe form of unhealthy alcohol use, is underutilized despite the availability of multiple effective medications. Although behavioral therapies are an important component of treatment, they are overemphasized at the expense of pharmacotherapy.

Prevalence and Improvement of Caine-Positive Wernicke-Korsakoff Syndrome in Psychiatric Inpatient Admissions.

BACKGROUND: Wernicke-Korsakoff Syndrome (WKS) resulting from thiamine deficiency is classically defined as including encephalopathy, ataxia, and ophthalmoplegia. Only 16% of autopsy-confirmed patients with WKS exhibit all three signs. Caine-positive WKS criteria include two or more of the following: nutritional deficiency, delirium or mild memory impairment, cerebellar dysfunction/ataxia, and oculomotor abnormalities. OBJECTIVE: We describe Caine-positive WKS prevalence among psychiatric inpatients and compare pretreatment-versus-posttreatment neurocognitive improvement to an unaffected group. METHODS: This 6-month quality-improvement evaluation included two-stage screening for Caine-positive WKS, administering high-dose intravenous thiamine (day 1: 1200 mg; days 2-4: 200 mg) with reexamination on day 5. We used descriptive statistics and fitted random effects models to examine rate-of-change differences in pre-/posttreatment Montreal Cognitive Assessment (MoCA), delayed 5-item recall, and gait/coordination scores between treated Caine-positive patients with WKS and untreated Caine-negative patients. RESULTS: Of 262 patients, 32 (12%) had Caine-positive WKS; 17 (53%) used alcohol currently. Treated Caine-positive WKS (n = 26) versus Caine-negative comparison (n = 34) before and after treatment observed a mean change (standard deviation) in the MoCA score of 3.6 (2.5) versus 1.8 (2.5) (P < 0.01); 5-item recall: 1.8 (1.4) versus 0.5 (1.4) (P < 0.001); gait/coordination scores: -0.6 (1.2) versus -0.1 (0.6) (P < 0.001). Oculomotor abnormalities were infrequent (n = 4 in Caine-positive WKS, n = 2 in Caine-negative comparison groups). CONCLUSIONS: Caine-positive WKS prevalence among psychiatric inpatients was 12%; only half used alcohol. Patients treated with high-dose thiamine demonstrated clinically significant neurocognitive improvement.

Addressing alcohol-related dementia should involve better detection, not watchful waiting.

Alcohol-related dementia represents an underrecognised mental disorder with both clinical and public mental health aspects. There is considerable scope for improving its assessment within both mainstream and specialist mental health services, but ongoing challenges remain in ensuring its timely detection so that appropriate preventative and rehabilitative interventions can be applied. Declaration of interest None.

Neuropsychiatric Symptoms in People With Korsakoff Syndrome and Other Alcohol-Related Cognitive Disorders Living in Specialized Long-Term Care Facilities: Prevalence, Severity, and Associated Caregiver Distress.

OBJECTIVES: Caring for people with Korsakoff syndrome (KS) residing in specialized long-term care facilities (LTCFs) can be distressing because of challenging neuropsychiatric symptoms (NPS). However, good-quality studies on NPS in this under-researched population are lacking. This study examined the prevalence and severity of NPS in people with KS living in specialized LTCFs and the associated caregiver distress. DESIGN: Cross-sectional, observational study. Data were obtained using structured interviews with care staff, elderly care physicians, and residents. SETTING: Nine specialized LTCFs in the Netherlands. PARTICIPANTS: KS residents admitted for at least 3 months. MEASUREMENTS: The prevalence and severity of NPS were measured with the Neuropsychiatric Inventory-Questionnaire (NPI-Q). The associated caregiver distress was assessed with the NPI Distress Scale (NPI-D) according to the nurse or nurse assistant. RESULTS: Almost all of the 281 residents (96.4%) showed at least 1 NPS and 45.8% showed 5 or more symptoms. Irritability/lability (68.3%), agitation/aggression (58.7%), and disinhibition (52.7%) were most prevalent. Although the mean level of severity for all NPS was relatively low, half of the residents (49.1%) had at least 1 severe NPS. Care staff experienced low levels of distress associated with NPS. CONCLUSION: NPS are highly prevalent in KS residents. Unexpectedly, these did not have any severe impact on residents and care staff. Acquiring more insight into the persistence and course of NPS, and its associations, among KS residents is important to better understand and reduce these symptoms and, ultimately, improve the quality of care for these residents.
