ABSTRACT Alcohol withdrawal syndrome is an acute condition secondary to total or partial reduction of alcohol consumption, characterized by self limited signs and symptoms and different degrees of severity. It can be complicated by several clinical and/or other psychiatric related problems. The objective of this article is to review the most important psychiatric complications to alcohol withdrawal syndrome as well as other psychiatric disorders associated with alcohol dependence as Wernicke Korsakoff and Marchiava Bignami syndromes. We aim to promote early diagnosis and treatment of these conditions, minimizing morbidity and mortality associated with them.

    ABSTRACT: Background Delirium is defined as an impairment of counsciousness and cognitive functions and is a common cause of disturbed behaviour in many patients with different somatic diseases and mental disorders. Most at risk are elderly, postoperative patients, critically ill patients and those with cancer in advanced stages. In psychiatric intensive care units patients with alcohol and sedative withdrawal related delirium are more often treated. Although delirium is a negative prognostic indicator leading to higher morbidity and mor- tality of patients, it often goes undetected and poorly managed. Conclusions Most recommendations for management of delirium are based on the nonpharmacologi- cal supportive care and prevention of delirium. It is also necessary to identify and treat the underlying causes. Antipsychotics are the mainstay of symptomatic pharmacological treatment and have been shown to be effective in treating symptoms of both hyperactive and hypoactive delirium. Although efficacy rates between typical and atypical antipsychotic agents are similar, the later are associated with fewer extrapyramidal side effects. Benzo- diazepines are usually preferred for withdrawal delirium or as an alternative or adjuvant to antipsychotics when these are ineffective or cause unacceptable side effects.

    ABSTRACT: This study aimed to test seeking behavior caused by alcohol and the drug effects on learning in the zebrafish, Danio rerio. Three treatments were conducted: acute, chronic and withdrawal, using 0.10%, 0.25%, 1.00% alcohol and control (0.00%) (vol/vol%). For the drug seeking behavior, we used a place preference paradigm (shuttle box tank) before and after alcohol exposure in acute (single exposure) and chronic (7days) treatments. We observed a change in the basal preference due to the association with alcohol only for 0.25% and 1.00% doses in both acute and chronic offering, indicating an alcohol-seeking behavior after the drug exposure. For the learning task, two treatments were tested: chronic alcohol exposure (26days including the learning period) and alcohol withdrawal (15days of alcohol exposure before the learning period). During the learning period, fish received light stimulus followed by food in a pre-defined area of the tank for 8 consecutive days. The low dose group (0.10%) learned the task by the 3rd day both in chronic and withdrawal treatments. The higher doses (0.25% and 1.00%) caused a learning impairment in the chronic treatment group, while fish from the alcohol withdrawal treatment displayed learning on the final testing day. Therefore, we suggest that high alcohol doses impair learning and cause drug seeking behavior, even after drug exposure cessation, while low doses positively affect learning and do not cause seeking behavior. Given our results we propose that the zebrafish is a promising model for identifying active compounds, antibodies or genes which modulate the alcohol dual effects: learning improvement and reinforcing behavior.
