Major discoveries have been made in the recent past in the genetics, biochemistry and neuropathology of frontotemporal lobar degeneration (FTLD). TAR DNA-binding protein 43 (TDP-43), encoded by the TARDBP gene, has been identified as the major pathological protein of FTLD with ubiquitin-immunoreactive (ub-ir) inclusions (FTLD-U) with or without amyotrophic(More)
Progressive supranuclear palsy (PSP) is the most common atypical parkinsonian syndrome comprising two main clinical subtypes: Richardson's syndrome (RS), characterized by prominent postural instability, supranuclear vertical gaze palsy and frontal dysfunction; and PSP-parkinsonism (PSP-P) which is characterized by an asymmetric onset, tremor and moderate(More)
We studied corticobulbar influence on the orbicularis oris (OR) muscles by anodal and magnetic transcranial stimulation and compared it to the corticospinal influence on first dorsal interosseous muscles of healthy human volunteers. We recorded single motor unit (MU) responses and applied peristimulus time histogram (PSTH) technique to determine their(More)
Amyotrophic lateral sclerosis (ALS) is a fatal disorder of motor neuron degeneration with unclear etiology and no effective treatment to date. ALS is, however, increasingly recognized as a multisystem disorder associated with impaired cognition. The overlap between ALS and dementia at clinical, genetic and neuropathologic levels indicates a spectrum of(More)
To investigate human corticobulbar projections, electromyographic responses from orbicularis oculi and orbicularis oris muscles were recorded in 11 healthy subjects after transcranial magnetic stimulation. Selective activation of lower facial motoneurones of one hemisphere was reached with the round coil 4 cm lateral to the vertex on a line to the external(More)
AIM To determine the stimulation site of both facial and hypoglossal nerves after transcranial magnetic stimulation. METHODS After surgical exposure of the brainstem in 22 patients with intrinsic pontine (n=9) or medullary (n=13) tumors, the facial colliculus and the hypoglossal triangle were electrically stimulated. The EMG responses were recorded with(More)
Behavioural disturbances are prominent in frontotemporal dementia (FTD), a focal, non-Alzheimer type of dementia. Although most patients with FTD present with socially inappropriate behaviour, compulsive-like acts, poor insight and disinhibition, the presence of psychiatric features including delusions, hallucinations, and paranoia can lead to a(More)
Frontotemporal dementias (FTD) are the second most common type of presenile dementias, considered to be clinically and pathologically different from Alzheimer's dementia (AD). FTD differs clinically from AD because memory loss is rarely an early symptom. Instead, FTD is usually denoted by behavioural and language difficulties, and may co-occur with motor(More)
The effects of chronic exposure to xylene on cognitive ability were studied in a group of 35 medical workers occupationally exposed to low-level concentrations of xylene for at least five years by using event-related potentials (ERPs), and compared with a control group of 21 subjects. The exposure to xylene was confirmed through determination of(More)
Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) are neurodegenerative disorders, related by signs of deteriorating motor and cognitive functions, and short survival. The cause is unknown and no effective treatment currently exists. For ALS, there is only a drug Riluzole and a promising substance arimoclomol. The overlap between ALS and(More)
