Unilateral asterixis due to a lesion of the ventrolateral thalamus.

چکیده
A case of unilateral asterixis in a man with a focal ischaemic lesion of the contralateral ventral thalamus is presented. Atypically, the movements were present at rest and had a pattern of activation that resulted in an initial misdiagnosis of epilepsia partialis continua. This case emphasises the importance of electromyographic analysis in establishing the correct diagnosis of involuntary movements before starting specific treatment.

Pathophysiology of unilateral asterixis due to thalamic lesion.
OBJECTIVE Unilateral asterixis has been reported in patients with thalamic lesion. This study aims at elucidating the pathophysiology of the thalamic asterixis. METHODS Two cases with unilateral asterixis caused by an infarction in the lateral thalamus were studied by analysing the asterixis-related cortical activities, transcranial magnetic stimulation (TMS) for motor cortex excitability and...
متن کاملEvaluation of specific lesion of ventrolateral PAG projecting to NRM by ibotenic acid using formalin test
It has been reported that neurons in the VL PAG projecting to nucleus raphe magnus (NRM) utilize excitatory amino acids as neurotransmitter. This projection plays an important role in the descending pain modulatory system. In order to determine the role of this pathway in pain perception, male rats received unilateral injection of ibotenic acid stereotaxically. For lesioning VL PAG, unilateral ...

Introduction: Spinal cord injuries are accompanied with significant demyelination of axons and subsequent locomotor dysfunction. To identify the extent of damage following electrolytic lesion of ventrolateral white matter, essential area for initiation of locomotor activity, we assessed demyelination as well as alteration in motor performance. Moreover, the protective effect of estradiol as a c...

Asterixis, firstly described in metabolic encephalopathies, may occur unilaterally in patients with various focal brain diseases. Although hardly localizing, most reported cases have showed a contralateral thalamic pathology; but Lesions in the medial frontal lobe, parietal lobe, brain stem, basal ganglia, insular lesions, may also cause unilateral asterixis. In this article, three cases of acu...
