Parasomnias are frequent. They usually represent either the exaggeration of a physiological phenomenon (e.g. sleep starts) or a non-disturbing, idiopathic and usually benign sleep disorder (e.g. sleep talking and bruxism), which need only counseling and improvement of sleep hygiene. However, occasionally parasomnias are of clinical relevance. They can cause insomnia or hypersomnia (e.g. 'myoclonus nocturnus'), psychosocial stress (e.g. sleep-related enuresis and sleep walking) and injuries to oneself and others (e.g. REM-parasomnia). Finally, they can be symptomatic of neurological and medical disorders (e.g. sleep paralysis and 'myoclonus nocturnus'). In these cases special investigations including video-polysomnography can establish a correct diagnosis and allow a specific treatment.

To define the incidence and type of neurological complications and associated factors, we reviewed 41 consecutive patients who had 45 procedures for liver transplantation. Encephalopathy occurred after 28 procedures (62%) with immediate onset and no significant recovery before death or re-transplantation in 11 (24%), slow recovery in eight (18%) and delayed onset (1-50 days, average 11) in six (13%). Intermittent confusion and agitation with full recovery followed three (6.6%), and focal and generalized seizures followed five (11%) procedures with multifocal myoclonus in two and status epilepticus in one; isolated focal seizures followed two and myoclonus or unclassified seizures, one each. All patients with seizures had encephalopathy. Three patients had neuropathy (2 generalised and 1 focal). Other complications included headache (2), tremors (2), fatigue (2), restlessness, nervousness, transient enuresis, intermittent dizziness, critical illness myopathy and detached retina. Brain imaging showed atrophy in three (6.6%) instances, intracerebral haemorrhage in two, multiple infarctions in one, and intracerebral and subarachnoid haemorrhage with infarction in one. Cerebrospinal fluid analysis showed increased protein in three, hemorrhage in one, and no abnormality in one patient. Of 12 patients (29%) who died before discharge, five in the first and three in the second week post-transplantation, 11 (92%) had encephalopathy post-operatively. Neurological complications after transplantation were associated with increased mortality. Post-operative hypomagnesaemia was associated with the development of nervous system complications. We did not identify any clear pre-operative predictors of development of post-operative neurological complications.

The recognition, management, and if possible prevention, of major cardiovascular, central nervous system, haematological, and metabolic adverse effects, including diabetes mellitus and weight gain, of antipsychotics and some other drugs used to treat mental illness is a topic of much debate. However, a wide range of other adverse effects, some of which may be life-threatening, may also be encountered. Side-effects reviewed here include: gastrointestinal-associated effects (constipation, hypersalivation, oropharyngeal lesions, nasal congestion, nausea, nocturnal enuresis, and urinary retention), metabolic effects (obesity, insulin resistance, dyslipidemia, impaired glucose tolerance, and hypertension), neuromuscular effects (extrapyramidal side effects, myoclonus, and neuroleptic malignant syndrome, and pleurothotonus), thermoregulatory effects, effects on the liver, pancreas, and kidney, sexual side effects, and effects on skin and bone. Metabolic factors affecting the incidence of adverse effects to clozapine especially are also discussed. The increasing use of atypical (second generation) antipsychotics and indeed of selective serotonin reuptake inhibitors has led to a greater appreciation of not only the benefits of these drugs, but also of the spectrum of toxicity that may occur in clinical practice. The adverse effects of antipsychotics are a major factor in promoting poor adherence to, and even discontinuation of, antipsychotic treatment on the one hand, and increasing the risk of cardiovascular and metabolic disease on the other. As such they merit recognition and either harm minimization strategies (use of the minimum effective dose, or use of lower doses of combinations of antipsychotics), or in extreme cases discontinuation of the offending drug(s).
