Extrapyramidal, frontal release, and other neurological signs were studied in 54 demented and non-demented patients with Down's syndrome (DS). Fourteen patients were demented and five showed extrapyramidal signs, mainly of the rigid-hypokinetic spectrum and similar to Parkinsonian features in advanced Alzheimer's disease (AD). None of the non-demented patients had Parkinsonian signs. The mean a...

BACKGROUND Extrapyramidal motor signs (EPS) are well-known symptoms of degenerative ataxia. However, little is known about frequency and appearance of EPS in subtypes of ataxia. METHODS We characterized 311 patients with ataxia clinically and genetically. Course of the disease and EPS were investigated according to a standardized protocol. Diagnostic and prognostic impact of EPS in subtypes o...

BACKGROUND Extrapyramidal signs (EPSs) are commonly accepted as a feature of Alzheimer disease (AD) and may influence both the profile of impairment and prognosis. OBJECTIVE To examine rates of occurrence and risk factors for all types of EPSs and to describe the impact of EPSs over time on the clinical course of AD. DESIGN Longitudinal study. SETTING The Washington Heights Hamilton Heigh...

background: pantothenate kinase associated neurodegeneration (pkan) is the most prevalent type of neurodegeneration with brain iron accumulation (nbia) disorders characterized by extrapyramidal signs, and 'eye-of-the-tiger' on t2 brain magnetic resonance imaging (mri) characterized by hypointensity in globus pallidus and a hyperintensity in its core. all pkan patients have homozygous or compoun...

We report an elderly patient who developed severe delirium and extrapyramidal signs after initiation of lithium-olanzapine combination. On hospital admission, serum levels of lithium were found to be 3.0 mM/L which were far above toxic level. Immediate discontinuation of both drugs resulted in complete resolution of most of the symptoms except for perioral dyskinesia which persisted for three m...

OBJECTIVE To describe a case of vitamin B(12) deficiency with classic and rare clinical features and novel radiographic features. DESIGN Case report. SETTING Johns Hopkins Hospital neurology service. PATIENT Middle-aged man with neuropathy, myelopathy,impaired cognition, and extrapyramidal signs. RESULTS The patient had neurologic and hematologic signs of vitamin B(12) deficiency, with ...

As a part of a large multidisciplinary clinical and research follow-up study, 47 Williams syndrome patients underwent detailed neurologic testing. Because previous studies have documented the absence of major neurologic signs in Williams syndrome, the neurologic testing focused on soft signs. Previous findings of impairment of both gross and fine motor coordination were confirmed, and the prese...
