چکیده

Neuroimaging has provided insight into the pathophysiology and natural history of Parkinson’s disease (PD) and has emerged as a tool to monitor disease progression and to assess new potentially neuroprotective or neurorestorative therapies for PD. Diverse imaging methods have been successfully applied to neurological disorders. While technology like functional magnetic resonance imaging or magnetic resonance spectroscopy has been especially useful in assessing stroke, multiple sclerosis and epilepsy (1–3), in vivo neuroreceptor imaging using single photon emission tomography (SPECT) and positron emission tomogrpahy (PET) have so far been most valuable in assessing PD. SPECT and PET use specific radioactively labeled ligands to neurochemically tag or mark normal or abnormal brain chemistry. Recent advances in radiopharmaceutical development, imaging detector technologies, and image analysis software have expanded and accelerated the role of imaging in clinical research in PD, in general, and neurotherapeutics, in particular. In this overview we will focus on developments in neuroreceptor imaging in PD.

Functional Neuroimaging in Parkinson’s Disease

The use of functional imaging in neurodegenerative diseases has increased in recent years, with applications in research into the underlying pathophysiology, aiding in diagnosis, or evaluating new treatments. In Parkinson’s disease (PD), these imaging methods have expanded our understanding of the disease beyond dopaminergic deficits. Moreover, functional imaging methods have described alterati...

SHORT REPORT Differentiation of Parkinson’s disease and atypical parkinsonian syndromes by transcranial ultrasound

Neuroimaging is known to complement clinical findings in the diagnostic work up of parkinsonian syndromes. Recently, transcranial ultrasound was reported to have a high diagnostic yield in differentiating idiopathic Parkinson’s disease (IPD) from atypical parkinsonian syndromes. This report summarises the sonographic findings of 102 patients with IPD, 34 patients with multiple system atrophy, a...

Non-motor signs and symptoms in Parkinson’s disease

Motor symptoms are cardinal clinical features of Parkinson’s disease (PD). Progress in drug therapy and rehabilitation has been presenting beneficial effect for motor symptoms. However, non-motor symptoms and signs in PD have been accumulated growing attentions and its amelioration may also give beneficial effect for PD patients’ and their care givers’ quality of life. In this mini-review, I ov...

Debates in neuroimaging and the contribution of studies in patients with Parkinson’s disease

ABSTRACT. The objective of the current review was to verify whether studies investigating lexical-semantic difficulties in patients with Parkinson’s disease (PD) support the Embodied Cognition model. Under this framework, it is predicted that patients with PD will have more difficulties in the semantic processing of action concepts (action verbs) than of motionless objects. We also verified how...
