Transdiagnostic approach to language and cognition in the logopenic variant of primary progressive aphasia and Alzheimer’s disease
… symptom. Speech and/or language deficits are the primary symptom in primary progressive aphasia (PPA), associated with frontotemporal lobar degeneration and Alzheimer’s disease (AD). Language deficits are also frequently found in other dementias like typical, amnestic AD. Progressive language …

Effects of Semantic Feature Analysis+Multimodal Communication Program for Word Retrieval and Switching Behavior in Primary Progressive Aphasia
Primary progressive aphasia (PPA) is a neurodegenerative condition characterized by language and cognitive decline. Word retrieval deficits are the most common PPA symptom, and contribute to impaired verbal expression. Intense semantic interventions show promise for improving word retrieval in …

Positron emission tomography in vivo characterisation of the pathology of frontotemporal dementia
… the behavioural variant FTD; non-fluent variant primary progressive aphasia; and semantic variant primary progressive aphasia. These are usually associated with either tau or TDP-43 pathology, with highly variable clinicopathological correlations. Neuroinflammation also contributes to the …

Medial Temporal Lobe Does Not Tell The Whole Story: Episodic Memory In ‘atypical’ Variants Of Alzheimer’s Disease
… AD that I focused here are logopenic variant of Primary Progressive Aphasia (lvPPA) and posterior cortical atrophy (PCA). The overarching theme of my thesis is to examine 1) whether the atypical cases of AD have episodic memory difficulty, and if so, 2) what brain areas are responsible for this …

AI-Based Speech Assessment of Cognitive Impairment Disorders
… Disease (AD), Frontotemporal Dementia (FTD), and Primary Progressive Aphasia (PPA). We show that AD subjects can be distinguished from healthy controls with 85.4% accuracy and that the Mini- Mental State Examination scores of the subjects can be predicted with a root mean squared error of 4.56, …

The Physiology of Dementia: Network reorganisation in progressive non-fluent aphasia as a model of neurodegeneration
The dementias are persistent or progressive disorders affecting more than one cognitive domain that interfere with an individual’s ability to function at work or home, and represent a decline from a previous level of function. In this thesis I consider the neurophysiology of dementia at a number of …
