Abstract Purpose of Review The sense of smell is today one of the focuses of interest in
aging and neurodegenerative disease research. In several neurodegenerative diseases …

Parkinson's disease (PD) is currently clinically defined by a set of cardinal motor features
centred on the presence of bradykinesia and at least one additional motor symptom out of …

Olfactory dysfunction is a common and early symptom of many neurodegenerative diseases,
particularly of Parkinson's disease and other synucleinopathies, Alzheimer's disease (AD) …

Objectives: We performed a systematic review to assess alterations in measures of diffusion
tensor imaging (DTI) in parkinsonian syndromes, exploring the potential role of DTI in …

Alzheimer's and Parkinson's diseases are the most prevalent neurodegenerative disorders.
Their etiologies are idiopathic, and treatments are symptomatic and orientated towards …

Objectives: To characterize different stages of Parkinson disease (PD)-related cognitive
decline using diffusion tensor imaging (DTI) and investigate potential relationships between …

Olfactory dysfunction is a frequent and early feature of patients with neurodegenerative
disorders such as Alzheimer's disease (AD) and Parkinson's disease (PD) and is very …

Diffusion tensor imaging (DTI) allows measuring fractional anisotropy and similar
microstructural indices of the brain white matter. Lower than normal fractional anisotropy as …

Pathology of neurodegenerative diseases can be correlated with intra-neuronal as well as
extracellular changes which lead to neuronal degeneration. The central nervous system …

Background Positive clinical outcomes are now well established for deep brain stimulation,
but little is known about the effects of long-term deep brain stimulation on brain structural …
