Intermittent Ocular Microflutter in a Patient with Acute-Onset Oscillopsia.

Saccadic intrusions are small involuntary saccadic movements that disrupt visual fixation. Among saccadic intrusions without intersaccadic intervals, ocular flutter and opsoclonus are prominent. The saccade amplitude can occasionally be very small, which is referred to as ocular microflutter.

Brain oscillatory activity during sleep shows unknown dysfunctions in early encephalopathy.

Electroencephalographic recordings in cirrhotic patients without overt hepatic encephalopathy (HE) have mainly been performed during wakefulness. Our aim was to quantify their alterations in nocturnal sleep electroencephalogram (EEG). In 20 patients and 20 healthy volunteers, we recorded a nocturnal digital polysomnography.

[Critical illness myopathy. Neurophysiological and muscular biopsy assessment in 33 patients].

Introduction: Critical illness patients may show marked weakness acquired in the Intensive Care Unit (ICU). There are some disagreements about the myopathic versus neuropathic damage in this condition, presumably due to the lack of reliable diagnostic criteria.

Aims: To report the neurophysiological findings in critical patients, to classify them in groups according to the electro-physiological data of myopathy, and to ascertain the rapport between the neurophysiological classification of myopathy and the muscle biopsy results.

P300 event-related potential in euthymic patients with bipolar disorder.

Auditory P300 event-related potential (ERP) and performance on Sustained Attention were evaluated in 24 euthymic bipolar patients and 38 healthy volunteers. There were no significant differences between groups, and performance in sustained attention had no significant influence in the P300 responses. P300 response might be driven by the presence of mood symptoms.
