Clinical Aspects of the Differential Diagnosis of Parkinson's Disease and Parkinsonism.

J Clin Neurol 2022 May;18(3):259-270

Department of Neurology, Chung-Ang University College of Medicine, Seoul, Korea.

Parkinsonism is a clinical syndrome presenting with bradykinesia, tremor, rigidity, and postural instability. Nonmotor symptoms have recently been included in the parkinsonian syndrome, which was traditionally associated with motor symptoms only. Various pathologically distinct and unrelated diseases have the same clinical manifestations as parkinsonism or parkinsonian syndrome. Read More

Therapeutic Application of rTMS in Atypical Parkinsonian Disorders.

Behav Neurol 2021 23;2021:3419907. Epub 2021 Dec 23.

Department of Neurology, University Hospital of Larissa, School of Medicine, University of Thessaly, Larissa, Greece.

The terms atypical parkinsonian disorders (APDs) and Parkinson plus syndromes are mainly used to describe the four major entities of sporadic neuronal multisystem degeneration: progressive supranuclear palsy (PSP), corticobasal degeneration (CBD), multiple system atrophy (MSA), and dementia with Lewy bodies (LBD). APDs are characterized by a variety of symptoms and a lack of disease modifying therapies; their treatment thus remains mainly symptomatic. Brain stimulation via repetitive transcranial magnetic stimulation (rTMS) is a safe and noninvasive intervention using a magnetic coil, and it is considered an alternative therapy in various neuropsychiatric pathologies.

Alteration of Mitochondrial Function in Oxidative Stress in Parkinsonian Neurodegeneration: A Cross-Sectional Study.

Ann Indian Acad Neurol 2021 Jul-Aug;24(4):506-512. Epub 2021 Apr 21.

Department of Laboratory Medicine, All India Institute of Medical Sciences, New Delhi, India.

Context: Appropriate mitochondrial function and oxidative balance are critical to neuronal survival. Accumulation of reactive oxygen species leads to oxidative stress that can cause free radical damage to biomolecules of the cell components and the molecules in the cellular milieu that eventually lead to a variety of chronic diseases including neurodegenerative disorders. Mitochondrial dysfunction initiates neuronal apoptosis thereby leading to neurodegenerative diseases including Parkinson's disease (PD). Read More

Molecular pathology and synaptic loss in primary tauopathies: an 18F-AV-1451 and 11C-UCB-J PET study.

Brain 2022 Mar;145(1):340-348

Department of Clinical Neurosciences, University of Cambridge, Cambridge Biomedical Campus, Cambridge CB2 0SZ, UK.

The relationship between in vivo synaptic density and molecular pathology in primary tauopathies is key to understanding the impact of tauopathy on functional decline and in informing new early therapeutic strategies. In this cross-sectional observational study, we determine the in vivo relationship between synaptic density and molecular pathology in the primary tauopathies of progressive supranuclear palsy and corticobasal degeneration as a function of disease severity. Twenty-three patients with progressive supranuclear palsy and 12 patients with corticobasal syndrome were recruited from a tertiary referral centre. Read More

J Geriatr Psychiatry Neurol 2022 01 19;35(1):57-61. Epub 2021 Jan 19.

Regionale Brain Aging Center, Department of Medicine (DIMED), University of Padova, Padova, Italy.

We report a case of a 77 years old patient who was admitted to our memory clinic because of progressive gait impairment and amnestic cognitive decline associated with extrapyramidal symptoms and behavioral changes. The clinical picture was consistent with a possible diagnosis of Alzheimer's Disease associated with parkinsonian symptoms or with a Parkinson Plus syndrome. After a complete investigation, she was found to have a high plasma level of homocysteine due to homozygous methylene-tetrahydrofolate reductase (MTHFR) gene C665 T polymorphism, cognitive and motor impairment were associated with a severe cortical atrophy and mild subcortical vascular disease.

Locus coeruleus pathology in progressive supranuclear palsy, and its relation to disease severity.

Acta Neuropathol Commun 2020 02 4;8(1):11. Epub 2020 Feb 4.

Cambridge University Centre for Parkinson-plus and Department of Clinical Neurosciences, University of Cambridge, Robinson Way, Cambridge, CB2 0SZ, UK.

The locus coeruleus is the major source of noradrenaline to the brain and contributes to a wide range of physiological and cognitive functions including arousal, attention, autonomic control, and adaptive behaviour. Neurodegeneration and pathological aggregation of tau protein in the locus coeruleus are early features of progressive supranuclear palsy (PSP). This pathology is proposed to contribute to the clinical expression of disease, including the PSP Richardson's syndrome. Read More

Parkinsonism in frontotemporal dementias.

James B Rowe

Int Rev Neurobiol 2019 21;149:249-275. Epub 2019 Nov 21.

Cambridge University Centre for Frontotemporal Dementia and Cambridge University Centre for Parkinson-plus, Cambridge University, Cambridge, United Kingdom.

Frontotemporal dementia is a clinically and pathologically heterogeneous group of neurodegenerative disorders, with progressive impairment of behavior and language. They can be closely related to amyotrophic lateral sclerosis, clinically and through shared genetics and similar pathology. Approximately 40% of people with frontotemporal dementia report a family history of dementia, motor neuron disease or parkinsonism, and half of these familial cases are attributed to mutations in three genes (C9orf72, MAPT and PGRN).

Recognizing and treating atypical Parkinson disorders.

Handb Clin Neurol 2019 ;167:301-320

Department of Neurology, University of Florida College of Medicine, Gainesville, FL, United States.

Though less common than Parkinson's disease (PD), the atypical Parkinson disorders such as such as dementia with Lewy bodies, multiple system atrophy, progressive supranuclear palsy, and corticobasal degeneration are increasingly recognized and important to distinguish from PD. Atypical or "Parkinson-plus" disorders are multisystem disorders and generally progress more rapidly and respond poorly to current therapies compared to PD. Recent advances in our understanding of the pathophysiology of these disorders, however, have generated new interest in the development of novel diagnostics and disease-modifying therapeutics aimed at identifying and treating these disorders.
