The central anticholinergic syndrome (CAS) includes central signs (somnolence, confusion, amnesia, agitation, hallucinations, dysarthria, ataxia, delirium, stupor, coma) and peripheral signs (dry mouth, dry skin, tachycardia, visual disturbances and difficulty in micturition). It occurs when central cholinergic sites are occupied by specific drugs and also as a result of an insufficient release of acetylcholine. The CAS can be caused by atropine sulphate, hyoscine (scopolamine), promethazine, benzodiazepines, opioids, halothane, influrane, ketamine. The incidence of CAS during the postoperative period depends on choice and dose of anaesthetic agents, type of surgery, patient's condition and diagnostic criteria. It is close to 10% following general anaesthesia and 4% following regional anaesthesia with sedation. The differential diagnosis of CAS includes an overdose of anaesthetic drugs or an alteration in pharmacokinetics, altered hydratation, electrolyte or acid-base state, hypoglycaemia, hypoxia, hypercapnia, hypocapnia, hyperthermia, hypothermia, hormonal disorders, neurological damage resulting from surgery, embolism, haemorrhage or trauma. The diagnosis of CAS is often determined by a process of exclusion and not actually made until a positive therapeutic response to physostigmine, a centrally active anticholinesterase agent has taken place.

An unusual case of Whipple's disease is reported. The diagnosis was difficult as the characteristic digestive sign and symptoms (malabsorption, diarrhea, mucosal infiltration by PAS-positive macrophages) were absent. After a ten-year history of seronegative arthritis, myocardiopathy, with aortic insufficiency, basilar pulmonary infiltrates, enlarged lymph nodes, the patient, a 56 years old man, was referred to us for a severe vegetative and neurological dysfunction: stupor, dysarthria, akinesia, hypertonia, hypothermia and abnormal thirst. A CT-scan showed a low-density area of the right hypothalamus, and PAS-positive macrophages were found in a lymph node, in the CSF and in a cerebral biopsy. The patient then received a classical antibiotic treatment, yet the neurologic dysfunction remained severe. Finally, a trial with rifampicin brought a striking improvement of the patient's condition, which has now lasted for three years.

The case of a 63-year-old woman who presented with status epilepticus, coma and hypoventilation is reported. A primary neurological cause was considered. Hypothermia led to further investigations and a diagnosis of severe hypothyroidism. The neurological complications of hyperthyriodism include alteration in mental status with slowness, decreased concentration and lethargy, headache, cranial nerve palsies, dysarthria, hoarseness, myopathy, neuropathy, reflex changes, ataxia, and psychotic episodes. Our patient suffered from a rare consequence of severe hypothyroidism presenting with status epilepticus and she died despite treatment. To our knowledge this is the second patient to be reported with myxoedema coma with this kind of presentation. Despite therapeutic options, there is a high mortality rate.

A 69-year-old woman was admitted due to gradual progression of daytime sleepiness and forgetfulness over a period of approximately 1 month. Bradycardia and hypothermia were observed on admission, and neurological examination revealed memory disturbance, mild dysarthria, and bradykinesia. Fluid-attenuated inversion recovery (FLAIR) images of the brain magnetic resonance imaging (MRI) indicated signal hyperintensity in the region bordering the lateral and third ventricles. Serum anti-aquaporin 4 (AQP4) antibody was detected. The patient had no history or findings of optic neuritis or myelitis, and she was diagnosed as anti-AQP4 antibody-associated disorder. Diencephalon lesion and/or symptoms are rarely observed at the onset of neuromyelitis optica. Differential diagnosis of this disorder is necessary in cases manifesting diencephalon symptoms or involving lesions bordering the third ventricle without evidence of previous optic neuritis or myelitis.
