athetosis/hemorrhage

BACKGROUND Athetosis is a slow and purposeless involuntary movement which changes in frequency, severity. The term pseudoathetosis is used when this movement is associated with proprioceptive sensory impairment. METHODS A 63 year old man developed right medulla and pons hemorrhage and presented loss

OBJECTIVE The authors retrospectively reviewed the efficacy and safety of Gamma Knife surgery (GKS) in patients with brainstem cavernous malformations (CMs). The CMs had bled repeatedly and placed the patients at high risk with respect to surgical intervention. METHODS Between 1993 and 2010, 49

The cerebral pareses occurring in early childhood or produced subsequently by trauma or spontaneous cerebral haemorrhages, present a heterogenous symptomatic picture. In the forefront we find the spastic pareses associated with extra-pyramidal motor hyperkinesia (athetosis, dystonia, ballism). 36

Hypertrophic olivary degeneration is a rare kind of trans-synaptic degeneration that occurs after lesions of the dentatorubro-olivary pathway. The lesions, commonly unilateral, may result from hemorrhage due to vascular malformation, trauma, surgical intervention or hypertension, tumor, or ischemia.

Among 848 cases of profound mental retardation with motor disturbance admitted to Metropolitan Medical Center of Severely Handicapped in the last 20 years, 98 died. The 94 cases whose cause of death was determined were clinically investigated. There was no difference in sex, and 72% of the patients

Although occurrence of involuntary movements after thalamic stroke has occasionally been reported, studies using a sufficiently large number of patients and a control population are not available. Between 1995 and 1999, the author prospectively identified 35 patients with post-thalamic stroke

Movement disorders can occur as primary (idiopathic) or genetic disease, as a manifestation of an underlying neurodegenerative disorder, or secondary to a wide range of neurological or systemic diseases. Cerebrovascular diseases represent up to 22% of secondary movement disorders, and involuntary
