Cognitive impairment in neurodegenerative diseases: insights from computational neuroimaging
Lebedev, Alexander (Doctoral thesis, 2014-09-02)Background: Cognitive impairment is a very common problem, especially in older individuals with major impact on quality of life, daily functioning, and healthcare. Its importance is expected to increase due to the demographic ... -
Large-scale resting state network correlates of cognitive impairment in Parkinson’s disease and related dopaminergic deficits
Lebedev, Alexander; Westman, Eric; Simmons, Andrew; Lebedeva, Aleksandra; Siepel, Françoise J.; Pereira, Joana B.; Aarsland, Dag (Peer reviewed; Journal article, 2014-04-03)Cognitive impairment is a common non-motor feature of Parkinson’s disease (PD). Understanding the neural mechanisms of this deficit is crucial for the development of efficient methods for treatment monitoring and augmentation ... -
Random Forest ensembles for detection and prediction of Alzheimer's disease with a good between-cohort robustness
Lebedev, Alexander; Westman, Eric; Westen, G. J. P. Van; Kramberger, M. G.; Lundervold, Arvid; Aarsland, Dag; Soininen, H.; Kłoszewska, I.; Mecocci, P.; Tsolaki, M.; Vellas, B.; Lovestone, S.; Simmons, Andrew (Peer reviewed; Journal article, 2014)Computer-aided diagnosis of Alzheimer's disease (AD) is a rapidly developing field of neuroimaging with strong potential to be used in practice. In this context, assessment of models' robustness to noise and imaging protocol ...
