This PhD thesis examines the relationship between Amyotrophic Lateral Sclerosis (ALS) and Frontotemporal dementia (FTD). ALS is a rapidly progressive neurodegenerative movement disorder characterized by muscle weakness, spasticity and abnormal reflexes. In a very small subset of patients (5-15%), ALS is associated with FTD. Furthermore, a larger subset of patients who do not suffer from overt dementia, develop subtle deficits in cognition and behaviour (up to 50%). The changes have mostly been observed in the domains of executive functions, language and behavioural functioning. These observations have led some researchers to propose a continuum of dysfunction between ALS and FTD, ranging from an absence of neuropsychological abnormalities to mild, subclinical changes to a profile consistent with a full-blown FTD-syndrome in ALS. FTD consists of three subsyndromes; the first 'executive-behavioural' type, frontal variant FTD (fvFTD), is predominantly characterized by behaviour abnormalities, difficulties with using strategies and social judgement. In contrast, the other two types mainly involve problems with 'language', including a central degradation of knowledge for words, objects, people (semantic dementia; SD) as well as complications with speaking, spelling and the sounds of language (progressive non-fluent aphasia; PNFA). The current study aims to explore whether the cognitive-behavioural deficits found in nondemented ALS-patients can be classified as subclinical forms of the first two FTDsyndromes, i.e. fvFTD and SD. In addition, the study further examined whether executive and language impairments co-exist or rather occur independently. To answer the research questions, a battery of neuropsychological tests was employed, adapted to patients' speech and motor disabilities, as well as behavioural questionnaires. The data revealed there was evidence of both executive and language involvement characteristic of FTD, albeit to a subtle extent. ALS-patients showed deficits on a test of Theory of Mind (ToM). On this test, participants were asked to judge the thoughts and feelings of another, using the direction of eye gaze, a cue considered to be important for social interaction. Results indicated that ALS patients had difficulties with affective ToM, i.e. recognizing feelings of others, and this effect was not driven by perceptual or attentional difficulties. In addition, patients exhibited a subtle deficit with empathy as well as a range of behavioural abnormalities. Furthermore, ALS-patients showed abnormal performance on a complex multi-modal semantic association task which involved assigning the correct picture iii to the sound of an object. This central deficit emerged in the presence of normal audio-visual information processing and episodic memory functions. Moreover, a category-specific deficit for man-made objects was detected in patients. Individual case-analyses showed that various subsets of patients were impaired on the language and executive tasks. These analyses also showed that executive and language problems can occur independently as well as simultaneously in patients with ALS. In addition, analysis of individual cases revealed that some patients' performance on the decision making tasks was similar to that found in patients with either orbitofrontal or dorsolateral dysfunction, while there was little if any evidence of a pattern of impairment similar to that seen with anterior cingulate dysfunction. The observed difficulties with social cognition and semantic processing indicate that executive and language problems, characteristic of the two FTD syndromes, can be detected in patients with classical ALS

The Neocerebellar Kalman Filter linguistic processor : from grammaticalization to transcranial magnetic stimulation by Giorgos P Argyropoulos( )

1 edition published in 2011 in English and held by 1 WorldCat member library worldwide

The present work introduces a synthesis of neocerebellar state estimation and feedforward control with multi-level language processing. The approach combines insights from clinical, imaging, and modelling work on the cerebellum with psycholinguistic and historical linguistic research. It finally provides the first experimental attempts towards the empirical validation of this synthesis, employing transcranial magnetic stimulation. A neuroanatomical locus traditionally seen as limited to lower sensorimotor functions, the cerebellum has, over the last decades, emerged as a widely accepted foundation of feedforward control and state estimation. Its cytoarchitectural homogeneity and diverse connectivity with virtually all parts of the central nervous system strongly support the idea of a uniform, domain-general cerebellar computation. Its reciprocal connectivity with language-related cortical areas suggests that this uniform cerebellar computation is also applied in language processing. Insight into the latter, however, remains an elusive desideratum; instead, research on cerebellar language functions is predominantly involved in the frontal cortical-like deficits (e.g. aphasias) seldom induced by cerebellar impairment. At the same time, reflections on cerebellar computations in language processing remain at most speculative, given the lack of discourse between cerebellar neuroscientists and psycholinguists. On the other hand, the fortunate contingency of the recent accommodation of these computations in psycholinguistic models provides the foundations for satisfying the desideratum above. The thesis thus formulates a neurolinguistic model whereby multi-level, predictive, associative linguistic operations are acquired and performed in neocerebello-cortical circuits, and are adaptively combined with cortico-cortical categorical processes. A broad range of psycholinguistic phenomena, involving, among others, "pragmatic normalization", "verbal/semantic illusions", associative priming, and phoneme restoration, are discussed in the light of recent findings on neocerebellar cognitive functions, and provide a rich research agenda for the experimental validation of the proposal. The hypothesis is then taken further, examining grammaticalization changes in the light of neocerebellar linguistic contributions. Despite a) the broad acceptance of routinization and automatization processes as the domain-general core of grammaticalization, b) the growing psycholinguistic research on routinized processing, and c) the evidence on neural circuits involved in automatization processes (crucially involving the cerebellum), interdisciplinary discourse remains strikingly poor. Based on the above, a synthesis is developed, whereby grammaticalization changes are introduced in routinized dialogical interaction as the result of maximized involvement of associative neocerebello-cortical processes. The thesis then turns to the first steps taken towards the verification of the hypothesis at hand. In view of the large methodological limitations of clinical research on cerebellar cognitive functions, the transcranial magnetic stimulation apparatus is employed instead, producing the very first linguistic experiments involving cerebellar stimulation. Despite the considerable technical difficulties met, neocerebellar loci are shown to be selectively involved in formal- and semantic-associative computations, with far-reaching consequences for neurolinguistic models of sentence processing. In particular, stimulation of the neocerebellar vermis is found to selectively enhance formal-associative priming in native speakers of English, and to disrupt, rather selectively, semantic-categorical priming in native speakers of Modern Greek, as well as to disrupt the practice-induced facilitation in processing repeatedly associated letter strings. Finally, stimulation of the right neocerebellar Crus I is found to enhance, quite selectively, semantic-associative priming in native speakers of English, while stimulation of the right neocerebellar vermis is shown to disrupt semantic priming altogether. The results are finally discussed in the light of a future research agenda overcoming the technical limitations met here

The truth about dementia( Visual )

1 edition published in 2016 in English and held by 1 WorldCat member library worldwide

Broadcaster Angela Rippon explores new scientific developments in dementia care and treatment, whilst undergoing a battery of tests to find out whether she carries the APOE gene and whether she is showing symptoms of the disease. She recounts her experiences caring for her mother, who developed dementia later in life. She then visits close friends, one of whom was diagnosed with Alzheimer's in his early eighties. Next, she visits a retirement community, where research into dementia is being conducted by Dr Jennifer Bute, who is a resident of the community and was diagnosed with dementia in her fifties. Bute recounts noticing the early signs of dementia, and talks Rippon through her coping strategies. Rippon visits Dr Claudia Wald, who conducts a cognitive test to find out if she is exhibiting symptoms of the disease. Clips of Rippon being examined in an MRI scanner are shown, from a programme she presented on aging. Rippon arranges for the scans to be sent for testing. She then visits Professor Janice Holton at Queen Square Brain Bank to explore what physically happens to the brain when it develops dementia. They compare a healthy brain and a brain exhibiting signs of Alzheimer's disease. Holton explains the function of the protein amyloid beta. Next, Rippon visits Neurologist Dr Angus Kennedy who analyses her brain scans. She then travels to a sleep clinic, where Neuroscientist Dr Jeff Iliff is conducting studies into the role deep sleep plays in staving off dementia. She then consults Dr Richard Perry about undergoing an APOE blood test to find out if she has an increased risk of developing Alzheimer's. Rippon meets Chris Graham, whose family have an inherited faulty gene that brings about familial early onset Alzheimer's Disease. Rippon visits Dr Catherine Mummery at the National Hospital for Neurology and Neurosurgery, who is conducting a trial involving families who hold this faulty gene. She then talks to Neuroscientist Dr Thomas Bak about the possibility that learning a second language might reduce the risk of developing dementia. She also visits Professor Claudia Kawas and one of her patients Mildred Patton. Kawas compares images of brain plaque in healthy and diseased brains. The show ends with Rippon discovering the results of her DNA test
