Wilson’s disease (WD) is an inherited metabolic disorder related to disturbances of copper metabolism, and predominantly presents with liver and neuropsychiatric symptoms. In most cases it can be successfully treated with anti-copper agents, and both liver function and neuropsychiatric symptoms typically improve. Treatment guidelines for WD include recommendations for anti-copper treatment as well as for the treatment of liver failure symptoms. Recently, recommendations for treatment of the neurological symptoms of WD have also been proposed. Although most WD patients present with psychiatric symptoms at some stage of the disease, currently there are no guidelines for the treatment of the psychiatric manifestations. Treatment of the psychiatric symptoms of WD is often guided by general psychiatric experience, which typically glosses over the specificity of WD, and can result in severe neurological and/or hepatic complications. Here we review and discuss the possible treatments available for the mood disturbances, psychosis, behavioral and cognitive disorders that can occur in WD, as well as their efficacy.

WD should be always considered in differential diagnosis of psychiatric disorders in young patients, especially if they present additional extrapyramidal or hepatic symptoms. It is also extremely important to remain cautious when drugs with high affinity to dopamine D2 receptors need to be initiated in patients already diagnosed with WD, as they may result in severe and often irreversible neurological complications.

Electroencephalogram (EEG) slowing is associated with clozapine side effects, e.g., sedation, and may predict treatment response during clozapine treatment. As olanzapine and clozapine share many pharmacological properties, we investigated whether EEG slowing during olanzapine treatment was related to therapy outcome and sleepiness in patients with schizophrenia. Participants were age- and gender-matched schizophrenic patients treated with olanzapine (n 54), receiving no pharmacological treatment (n 54), or cotreated with olanzapine and some other psychotropic drug (n 38). Their EEG recordings were assessed visually by the same rater blind to clinical data. The EEG scores were categorized using standardized forms. Patients with a poor treatment response did not differ significantly from those with a good response to treatment either in EEG patterns or in frequency of sleepiness. Olanzapine treatment was associated with increased rates of slow (70.4% vs. 22.3%) and sharp waves (22.2% vs. 7.4%), as well as of paroxysmal slow wave discharges (14.8% vs. 1.9%), but did not induce spike- or sharp-slow-wave complexes. Cotreatment with another antipsychotic further increased EEG abnormalities, whereas benzodiazepine administration diminished the olanzapine-induced EEG changes. The results show that olanzapine inducing both slow and sharp waves, as well as paroxysmal discharges, has a strong impact on EEG. However, as no spike- or sharp-slow-wave complexes were observed, the risk of epileptic seizure during olanzapine treatment can be regarded as low, as long as olanzapine is not combined with some other antipsychotic.

Recent decades have seen development of research and an increased interest in the psychopharmacology of natural remedies. More than 20 herbal remedies have been identified that may potentially be applied in medicine as antidepressive, anxiety relieving or sleep-inducing agents. Patients often prefer to take herbal remedies and often take them on their own, without consulting a physician. The aim of the study is to present the state of the art concerning the use of natural remedies in the treatment of depression. Following a literature review, 7 herbal remedies for which preclinical and clinical trials suggest their antidepressive influence have been identified: hypericum, lavender, borage, roseroot, chamomile, saffron and ginseng. For two of these, i.e. hypericum and saffron extracts, antidepressive effect in subjects with mild or moderate depression has been confirmed in controlled randomized clinical trials.

The aim of the study was to analyze the antioxidant character of conched chocolate milk masses, taking into account different protein content in milk. For the study, cocoa liquor obtained from roasted and unroasted cocoa beans from different regions, as well as milk powder obtained by spray and cylindrical drying were used. The analysis that was carried out showed that the protein content of powdered milk products ranged from about 11.6% (w/w) to over 31% (w/w). Lower content of polyphenols and lower antioxidant activity were shown in the masses to which the addition of milk with higher protein content was applied. The analysis of antioxidant character of chocolate milk masses showed higher total polyphenols content in masses prepared from unroasted cocoa beans liquor.

Serotonergic-type side effects (like diarrhoea, hyperthermia, nausea, confusion) were seen after phototherapy in patients receiving fluoxetine or sertraline. Phototherapy was discontinued and symptoms completely resolved. In the authors' opinion, the symptoms were likely to be associated with specific interaction (serotonin effect potentialisation). To the authors' knowledge this is the first report concerning such an effect.
