Functional magnetic resonance imaging (fMRI) has been used to study the neural bases of cognitive deficits in Parkinson's disease for several years.

Functional MRI (fMRI) has been widely used to study abnormal patterns of brain connectivity at rest and activation during a variety of tasks in patients with idiopathic Parkinson's disease (PD). fMRI studies in PD have led to a better understanding of many aspects of …

Functional MRI (fMRI) has been widely used to study abnormal patterns of functional connectivity at rest in patients with movement disorders such as idiopathic Parkinson's disease (PD) and atypical parkinsonisms. This manuscript provides an educational review of the current use of resting‐state fMRI in the field of parkinsonian syndromes.

Jan 1, 2018 · Functional MRI (fMRI) provides insights into the mechanisms of brain adaptation and plasticity to damage related to many clinical symptoms in PD and has further extended our ability to understand the functional significance of pathological changes in this disease.

In this work, we model the 'effective' connectivity underlying low frequency blood oxygen level-dependent fluctuations in the resting Parkinsonian motor network-disclosing the distributed effects of deep brain stimulation on cortico-subcortical connections.

Because structural brain imaging using conventional MRI (cMRI) with visual assessment of T2- and T1-weighted sequences is usually normal in patients with early PD, its main role is detecting or ruling out other underlying pathologies causing parkinsonism (Mahlknecht et al. 2010).

With technological advances, there is an emerging use of functional magnetic resonance imaging (fMRI) after DBS implantation to explore the effects of stimulation on brain networks in PD.

Jan 1, 2019 · Functional magnetic resonance imaging (fMRI) has been used to study the neural bases of cognitive deficits in Parkinson's disease for several years.

fMRI has been widely used to study abnormal patterns of brain connectivity at rest and activation during a variety of tasks in patients with Parkinson’s disease. fMRI studies in Parkinson’s have led to a better understanding of many aspects of the disease, including both motor and non-motor symptoms. fMRI does not directly measure neural activity.

Dec 3, 2024 · Magnetic Resonance Imaging (MRI) has emerged as a valuable tool for investigating the structural and functional brain changes associated with cognitive impairment in PD (PD-CI). MRI techniques enable the precise identification and monitoring of the onset and progression of cognitive deficits in PD.
