We investigated primary motor cortex and brain stem plasticity in patients with Gilles de la Tourette syndrome. The study group comprised 12 patients with Gilles de la Tourette syndrome and 24 healthy subjects. Patients were clinically evaluated using the Yale Global Tic Severity Scale. We tested cortical plasticity by conditioning left primary motor cortex(More)
The histories of seven patients over the age of 60 years are reported. They all suffered from recurrent and prolonged episodes of confusional state associated with psychic and neurologic manifestations. All episodes were accompanied by the occurrence of periodic lateralized epileptiform discharges (PLEDs) on the EEG, which became normal when the ictal(More)
Recent experimental evidence has suggested that peripheral benzodiazepine receptors (PBR) may play a role in epilepsy and antiepileptic drug action. Since PBR are also present in circulating lymphocytes, and may interact with anticonvulsant drugs, this study was designed to look for possible modifications of these receptors and their endogenous ligand(More)
The term Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcus infections (PANDAS) was coined by Swedo et al. in 1998 to describe a subset of childhood obsessive-compulsive disorders (OCD) and tic disorders triggered by group-A beta-hemolytic Streptococcus pyogenes infection. Like adult OCD, PANDAS is associated with basal ganglia(More)
Transient hemiballismus was observed in a 74-year-old man, displaying subclavian steal syndrome. Such a correlation has not been previously reported in the literature. In this case, transient hemiballismus seemed to depend on hemodynamic factors, but other mechanisms possibly explaining early recovery of the hyperkinesias are discussed. In particular,(More)
76 cases of cluster headache are reviewed. Besides confirming established notions, the present study calls attention to the following points: (a) the peculiar behaviour of patients during the attacks does not appear explainable in simple terms of reaction to pain; (b) the occurrence of ECG abnormalities during the attacks in addition to bradycardia; (c) the(More)
OBJECTIVE To investigate the frequency of bradykinesia in patients with obsessive-compulsive disorder (OCD) and to see whether patients with OCD who also have bradykinesia display distinctive neuropsychological and neuropsychiatric features. METHODS We studied 23 antipsychotic-free patients with OCD and 13 healthy controls. Bradykinesia was assessed with(More)
In young adult life a large proportion of mentally retarded subjects develop psychiatric complications, both severe and mild, whose origin is undoubtedly multifactorial (biological and psychological). A series of 27 subjects (13 male, 14 female; mean age 27.6 years) with IQ ranging from 70 to 40 were studied in our Institute from 1994 to 1995 and followed(More)
