Ataxia telangiectasia (AT) is a rare autosomal recessive disorder characterized by progressive ataxia, neurodegeneration, immunodeficiency, and cancer predisposition. Pathoanatomical studies reported a degeneration of cerebellar Purkinje cells as the striking feature of the disease. Although recent studies suggested the involvement of extracerebellar(More)
This article summarizes evident and recent findings on the characteristics of the neurological phenotype in ataxia telangiectasia (AT), reviews neuropathological and neuroradiological findings, and outlines therapeutic treatment options. In addition, this review offers an overview of current hypotheses on mechanisms of neurodegeneration in AT and discusses(More)
AIMS The spinocerebellar ataxia type 2 (SCA2), type 3 (SCA3) and type 7 (SCA7) are clinically characterized by progressive and severe ataxic symptoms, dysarthria, dysphagia, oculomotor impairments, pyramidal and extrapyramidal manifestations and sensory deficits. Although recent clinical studies reported additional disease signs suggesting involvement of(More)
BACKGROUND Ataxia telangiectasia (A-T) is a devastating human recessive disorder characterised by progressive cerebellar ataxia, immunodeficiency, genetic instability, and cancer susceptibility. In addition, many patients suffer from growth failure. METHODS We analyzed growth and IGF-1/BP3 levels of 24 A-T-patients compared with an age-matched group of(More)
Huntington's disease (HD) is a polyglutamine disease and characterized neuropathologically by degeneration of the striatum and select layers of the neo- and allocortex. In the present study, we performed a systematic investigation of the cerebellum in eight clinically diagnosed and genetically confirmed HD patients. The cerebellum of all HD patients showed(More)
A 46-year-old woman with known situs inversus totalis and recent mitral valve replacement presented with nausea and vomiting. Ultrasonography demonstrated a left-sided microlithiasic gall-bladder. Laparoscopic cholecystectomy was performed successfully. The postoperative recovery was uneventful. The literature on this subject is reviewed.
Emotion attribution (EA) from faces is key to social cognition, and deficits in perception of emotions from faces underlie neuropsychiatric disorders in which cerebellar pathology is reported. Here, we test the hypothesis that the cerebellum contributes to social cognition through EA from faces. We examined 57 patients with cerebellar disorders and 57(More)
Pediatric MS tends to present more often with an acute onset and a polysymptomatic form of the disease, possibly with encephalopathy and large tumefactive lesions similar to those observed in some cases of acute disseminated encephalomyelitis (ADEM), which makes it more difficult to differentiate between an explosive and severe onset of MS vs. ADEM. An(More)
The cerebellar cognitive affective syndrome (CCAS) includes disruption of linguistic processing such as verbal fluency, verbal working memory, grammar, and speech perception. We set out to examine linguistic capabilities in patients with cerebellar lesions to determine which domains are spared and which impaired and to evaluate the underlying cognitive(More)
Small two-stroke gasoline engines are the major power source for professional outdoor power equipment such as hedge trimmers, chain saws, blowers and cut-off saws. However, electric motors energized with Lithium-Ion-based batteries as a power source strongly catch up. For some time now, small non-professional equipment with a battery-based power source is(More)
