OBJECTIVE An investigator-initiated, multicenter, randomized, placebo-controlled, double-blind clinical trial to determine whether coenzyme Q10 (CoQ10) is safe, well tolerated, and effective in slowing functional decline in progressive supranuclear palsy (PSP). METHODS Sixty-one participants received CoQ10 (2,400 mg/d) or placebo for up to 12 months. Progressive Supranuclear Palsy Rating Scal...

Progressive supranuclear palsy (PSP) has been described as a clinical syndrome characterized by an impairment of voluntary control of gaze (supranuclear palsy), postural and gait instability, and behavioral and cognitive deficits including a frontal syndrome and psychic retardation. However, in the recent years, at least four other clinical forms of PSP have been recognized: PSP-Parkinsonism, "...

Whilst many reports mention neurofibrillary tangle pathology in the thalamus in progressive supranuclear palsy, there has been little detailed regional analysis of the distribution and density of thalamic pathology in this disease or in other parkinsonian syndromes. The caudal intralaminar thalamic nuclei are the major thalamic regulators of the caudate nucleus and putamen, areas known to be dy...

A female with the Brown-Vialetto-Van Laere syndrome is described. The patient's father, a paternal uncle, and possibly a paternal first cousin had neurosensory deafness and a paternal aunt had clinical symptoms indicative of the syndrome. This family raises the possibility that the disorder is genetically heterogeneous with autosomal recessive and autosomal dominant forms. Alternatively, it cou...

We report a case of recurrent laryngeal nerve palsy caused by coalworkers' pneumoconiosis with progressive massive fibrosis (PMF). This illustrates that PMF alone may be added to the list of lesions which can cause recurrent laryngeal nerve palsy. However, efforts should always be made to exclude more common causes, in particular bronchogenic carcinoma, before attributing the palsy to PMF.

Although magnetic resonance imaging is a standard investigation in neurodegenerative disease, sensitive and specific markers for the underlying histopathological diagnosis are largely lacking. This report presents evidence to indicate that corticobasal degeneration and progressive supranuclear palsy, in particular, might be identifiable at a single subject level with diffusion tensor imaging. P...

Patients with Horizontal Gaze Palsy with Progressive Scoliosis The recent report in AJNR by dos Santos et al shows a case of MR imaging features in a child with horizontal gaze palsy with progressive scoliosis. This rare disorder has recently been shown by Jen et al to be secondary to defective brain stem crossing of descending corticospinal and somatosensory axons due to mutations in the ROBO3...

Cognitive impairment is integral to the syndrome of progressive supranuclear palsy. It is most commonly described as a frontal dysexecutive syndrome but other impairments include apathy, impulsivity, visuospatial and memory functions. Cognitive dysfunction may be exacerbated by mood disturbance, medication and communication problems. In this review we advocate an individualized approach to mana...

The corticobasal degeneration syndrome has been suggested to be part of a complex of conditions (including the different subtypes of frontotemporal dementia and progressive supranuclear palsy), which reflect a spectrum of pathological substrates. This concept is supported by the frequent clinical overlap that can be observed among patients diagnosed with these conditions. We report three clinic...

We report two patients diagnosed to have familial amyotrophic lateral sclerosis (FALS). A 40 year old lady had progressive weakness and atrophy of the limbs and bulbar palsy from the age of 39 years and with electrophysiological evaluation was confirmed as definite ALS. Her mother had presented in 1978 at the age of 42 years with symptoms and signs of ALS. The other patient was a 43 year old ma...
