We report an autopsy case of dementia associated with amyotrophic lateral sclerosis (ALS) in a 73-year-old female. She developed memory impairment at the age of 68 years. Atrophy of her hand muscles was noted at the age of 71 years. She was not aware of her memory impairment or muscle weakness, and
Brain imaging techniques, especially those based on magnetic resonance imaging (MRI) and magnetoencephalography (MEG), have been increasingly applied to study multiple large-scale distributed brain networks in healthy people and neurological patients. With regard to neurodegenerative disorders,
OBJECTIVE
To report the rare but distinct clinical and neuropathological phenotype of non-familial, rapidly progressive parkinsonism and dementia associated with frontotemporal lobar degeneration with motor neuron disease (FTLD-MND).
METHODS
Subjects included two 70-year-old women presenting with
BACKGROUND
Frontotemporal lobar degeneration (FTLD) represents a clinically, pathologically and genetically heterogenous neurodegenerative disorder, often complicated by neurological signs such as motor neuron-related limb weakness, spasticity and paralysis, parkinsonism and gait disturbances.
Motor neuron disease (MND) is a neurodegenerative condition long thought to be associated only with motor weakness. Recent work now shows that cognitive difficulties are present in up to half of the patients with this disorder. About 5-10% of patients with MND have a frank dementia that resembles
The transactive response DNA binding protein (TDP-43) proteinopathies describe a clinico-pathological spectrum of multi-system neurodegeneration that spans motor neuron disease/amyotrophic lateral sclerosis (MND/ALS) and frontotemporal lobar degeneration (FTLD). We have identified four male patients
OBJECTIVE
To investigate the molecular defect underlying a large Italian kindred with progressive adult-onset respiratory failure, proximal weakness of the upper limbs, and evidence of lower motor neuron degeneration.
METHODS
We describe the clinical features of 5 patients presenting with prominent
We report two unusual autopsy cases with frontotemporal lobar degeneration (FTLD) that were hyperphosphorylated-tau- and TAR DNA binding protein 43 (TDP-43)- negative. The behavioral symptoms in both cases were compatible with frontotemporal dementia, but they exhibited more prominent speech and
OBJECTIVE
Case reports and a review of literature of the coexistence of motor neuron disease (MND) and frontotemporal dementia (FTD).
METHODS
All three patients demonstrated generalized lower motor neuron signs and very few upper motor neuron signs. In the level of patterns of cognitive impairments,
The variable clinical course of Amyotrophic Lateral Sclerosis (ALS) confronts the clinician, the patient and caregivers with many ethical challenges from the moment of breaking the news of the diagnosis and throughout the relentlessly progressive trajectory of the disease. Each patient faces the
TAR DNA-binding protein 43 (TDP-43) has been identified as the major constituent of the proteinaceous inclusions that are characteristic of most forms of amyotrophic lateral sclerosis (ALS) and ubiquitin positive frontotemporal lobar degeneration (FTLD). Wild type TDP-43 inclusions are a
While both neuronal intermediate filament inclusion disease (NIFID) and basophilic inclusion body disease (BIBD) show frontotemporal lobar degeneration and/or motor neuron disease, it remains unclear whether, and how, these diseases differ from each other. Here, we compared the clinicopathological
Mutations in the fused in sarcoma (FUS) gene have been associated with amyotrophic lateral sclerosis (ALS), frontotemporal lobar degeneration, and essential tremor. Among the FUS mutations, p.P525L as a hot spot variant has been reported in more than 20 patients with ALS. Apart from Mutations in fused in sarcoma (FUS), a DNA/RNA binding protein, have been associated with familial amyotrophic lateral sclerosis (fALS), which is a fatal neurodegenerative disease that causes progressive muscular weakness and has overlapping clinical and pathologic characteristics with
Amyotrophic lateral sclerosis is characterised by a loss of upper and lower motor neurons and characteristic muscle weakness and wasting, the most common form being sporadic disease with neuronal inclusions containing the tar DNA-binding protein 43 (TDP-43). Frontotemporal lobar degeneration is
