Pallido-pyramidal syndrome treated with levodopa.

Pallido-pyramidal syndrome treated with levodopa.

Two siblings are reported who developed classical signs and symptoms of Parkinsonism in the first decade of life. In addition, they had evidence of cortical spinal tract disease, thus putting them in the category of Davison's pallido-pyramidal syndrome. Both deteriorated to the point of a non-productive existence until the institution of levodopa treatment, at the ages of 18 and 20 years. The r...

Pallido-pyramidal syndrome: a rare entity.

Kufor-Rakeb syndrome, pallido-pyramidal degeneration with supranuclear upgaze paresis and dementia, maps to 1p36.

Kufor-Rakeb syndrome is an autosomal recessive nigro-striatal-pallidal-pyramidal neurodegeneration. The onset is in the teenage years with clinical features of Parkinson's disease plus spasticity, supranuclear upgaze paresis, and dementia. Brain scans show atrophy of the globus pallidus and pyramids and, later, widespread cerebral atrophy. We report linkage in Kufor-Rakeb syndrome to a 9 cM reg...

Comparison of Endothelial Progenitor Cells in Parkinson's Disease Patients Treated with Levodopa and Levodopa/COMT Inhibitor

BACKGROUND Levodopa treatment in Parkinson's disease (PD) increases in serum homocysteine levels due to its metabolism via catechol O-methyltransferase. Endothelial progenitor cells (EPCs) have the capacity to differentiate into mature endothelial cells and are markers for endothelial functions and cardiovascular risks. Along with traditional vascular risk factors, hyperhomocysteinemia is known...

Holmes Tremor After Brainstem Hemorrhage, Treated With Levodopa

Holmes tremor is a rare movement phenomenon, with atypical low-frequency tremor at rest and when changing postures, often related to brainstem pathology. We report a 70-year-old female patient who was presented with dystonic head and upper limb tremor after brainstem hemorrhage. The patient had experienced a sudden onset of left hemiparesis and right facial paralysis. Brain magnetic resonance i...
