DJ-1 mutations and parkinsonism-dementia-amyotrophic lateral sclerosis complex.

2005

Mutations in DJ-1 gene have been recently shown to cause autosomal recessive early-onset Parkinson’s disease (EOPD) in a large Dutch family and in a small consanguineous Italian family.1 Subsequent to this initial finding, several additional DJ-1 mutations were identified in subjects with EOPD.2–6 We describe a family from southern Italy with three brothers affected by a complex disorder characterized by early-onset parkinsonism-dementia-amyotrophic lateral sclerosis (EOPD-D-ALS). The analysis of the DJ-1 gene showed a novel homozygous mutation (E163K) in exon 7 and a novel homozygous mutation (g.168_185dup) in the promoter region of this gene in living affected subjects

Sporadic Parkinson disease and amyotrophic lateral sclerosis complex (Brait-Fahn-Schwartz disease).

2012

Clinical evidence for parkinsonism may accompany Amyotrophic Lateral Sclerosis with a frequency ranging from 5% to 17%. The concurrence of Amyotrophic Lateral Sclerosis and Parkinson's disease, outside the known Guam and Kii Peninsula foci, is instead rare, but this raises the possibility of a common pathogenesis. Clinically this complex presents with a levodopa-responsive parkinsonism and Amyotrophic Lateral Sclerosis and has been termed Brait-Fahn-Schwartz disease. Here we describe two patients with this uncommon neurodegenerative complex. Both presented with Parkinson disease and progressed to a full blown Amyotrophic Lateral Sclerosis. We further suggest that the association of Parkinso…

Is Transcranial Magnetic Resonance Imaging-Guided Focused Ultrasound a Repeatable Treatment Option? Case Report of a Retreated Patient With Tremor Co…

2019

Introduction In recent years, transcranial Magnetic Resonance Imaging-guided Focused Ultrasound (tcMRgFUS) treatments for functional neurological disorders are giving a new thrust to the field of therapeutic brain lesioning. Objective To present the case of a patient affected by tremor combined with Parkinsonism who underwent a second tcMRgFUS thalamotomy because of relapsing tremor after a few months from the first tcMRgFUS treatment. Methods A 72-yr-old, right-handed man, came to our observation because of a disabling tremor affecting his upper limbs, refusing any invasive surgical procedure and already treated by tcMRgFUS left Vim thalamotomy. However, clinical benefit had brief duration…

Italian consensus recommendations for a biomarker‐based aetiological diagnosis in mild cognitive impairment patients

2019

Background and purpose: Biomarkers support the aetiological diagnosis of neurocognitive disorders in vivo. Incomplete evidence is available to drive clinical decisions; available diagnostic algorithms are generic and not very helpful in clinical practice. The aim was to develop a biomarker-based diagnostic algorithm for mild cognitive impairment patients, leveraging on knowledge from recognized national experts. Methods: With a Delphi procedure, experienced clinicians making variable use of biomarkers in clinical practice and representing five Italian scientific societies (neurology – Società Italiana di Neurologia per le Demenze; neuroradiology – Associazione Italiana di Neuroradiologia; b…

Chemical intervention in senescence-accelerated mice metabolism for modeling neurodegenerative diseases: an overview

2004

Abstract SAMP1 is a line of inbred mice with a pronounced misbalance between generation and neutralization of reactive oxygen species (ROS) in brain and other tissues. This results in accumulation of molecular defects in lipids, proteins and DNA moieties. The metabolic disorders appear at a very early stage of ontogenic development and induce morphological and behavioral defects manifesting from the fourth month after birth. 1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) treatment of these mice induced specific changes that closely resembled parkinsonian syndrome. Neuropeptide carnosine prevented toxic effects of MPTP and protected the animals against experimental parkinsonism.

Cognitive Deficits and Associated ERP N400 Abnormalities in FXTAS With Parkinsonism

2018

Objective: To examine cognitive deficits and associated brain activity in fragile X-associated tremor/ataxia syndrome (FXTAS) patients with parkinsonism (FXTp+), in relation to FXTAS patients without parkinsonism (FXTp-), and normal elderly controls (NC). Methods: Retrospective reviews were performed in 65 FXTAS patients who participated in the event-related brain potential (ERP) study and also had either a videotaped neurological examination or a neurological examination for extrapyramidal signs. Parkinsonism was defined as having bradykinesia with at least one of the following: rest tremor, postural instability, hypermyotonia, or rigidity. Eleven FXTp+ patients were identified and compare…

Characteristics of Bipolar Patients with Cognitive Impairment of Suspected Neurodegenerative Origin: A Multicenter Cohort

2021

Bipolar disorder is associated with an increased risk of dementia with aging. Little is known regarding this association, limiting appropriate diagnosis and management. We aimed to describe the characteristics of bipolar patients with late cognitive impairment for whom the hypothesis of an underlying neurodegenerative disease had been raised. We performed a retrospective multicenter study, recruiting bipolar patients over 50 years old from five French tertiary memory centers who had undergone cerebrospinal fluid (CSF) biomarker assessment for Alzheimer’s disease (AD). Clinical, neuropsychological, and paraclinical characteristics were analyzed and 78 patients were included. The mean age at …

Fabry Disease With Concomitant Lewy Body Disease

2019

AbstractAlthough Gaucher disease can be accompanied by Lewy pathology (LP) and extrapyramidal symptoms, it is unknown if LP exists in Fabry disease (FD), another progressive multisystem lysosomal storage disorder. We aimed to elucidate the distribution patterns of FD-related inclusions and LP in the brain of a 58-year-old cognitively unimpaired male FD patient suffering from predominant hypokinesia. Immunohistochemistry (CD77, α-synuclein, collagen IV) and neuropathological staging were performed on 100-µm sections. Tissue from the enteric or peripheral nervous system was unavailable. As controls, a second cognitively unimpaired 50-year-old male FD patient without LP or motor symptoms and 3…
