We need to improve: Diagnostic utility Ecological validity Trial outcome measures Scientific understanding . dennis.chan@ucl.ac.uk: My primary area of interest is the detection of Alzheimer’s disease (AD) in its earliest stages. Three groups of 10 subjects were studied: semantic dementia patients, Alzheimer's disease patients, and control subjects. However, carrying out clinical trials in early disease stages is extremely challenging-a key reason being the unfeasibility of using classical outcome measures of dementia tri... Impairments in spatial processing due to hippocampal degeneration have been observed in the years immediately preceding the diagnosis of Alzheimer's disease (AD) dementia. Simvastatin is an attractive drug with potentially anti-inflammatory (e.g., reducing leukocyte migration) and neuro-protective effects (e.g., up-regulation of the major cell survival protein bcl-2), in addition to being well tolerated. Anglia Ruskin University. Numerous imaging studies have confirmed the amygdala as prominent within a neural network mediating specific phobia, including arachnophobia. See Less.

Alzheimer's disease (AD) and semantic dementia (SD) are characterized by different patterns of global and temporal lobe atrophy which can be studied using magnetic resonance imaging (MRI). Patient N.T. Objective: Accumulating evidence suggests that grapheme-colour synaesthesia, a condition in which letters or numbers automatically elicit a secondary colour experience, facilitates memory for visual associations1,2. suffered dense, temporally ungraded, RA following a right temporal lobectomy for intractable epilepsy.

The cognitive consequences of the COVID-19 epidemic: collateral damage? The hippocampus plays a crucial role within the neural systems for long‐term memory, but little if any role in the short‐term retention of some types of stimuli. The recruitment of secondary progressive multiple sclerosis (SPMS) patients to the MS-STAT trial (a double-blind randomised placebo-controlled trial of high dose simvastatin) provided an opportunity to evaluate the frequency and severity of cognitive and neuropsychiatric symptoms at baseline, in this phase of the disease. Initial MRI brain scanning revealed a focus of subtle abnormal high signal withi...

His preclinical and clinical undergraduate training was split by a first period of doctoral research supervised by Professor John O’Keefe, University College London (UCL), who was later awarded the 2014 Nobel Prize in Physiology or Medicine. This study tested the hypothesis that mid-life intellectual, physical and social activities contribute to cognitive reserve (CR). The hippocampus is one of the earliest brain regions affected in Alzheimer's disease (AD) and tests of hippocampal function have the potential to detect Alzheimer's disease (AD) in its earliest stages. Formal testing disclosed that the patient experienced colour after-images of abnormal latency, duration, and amplitude.The demons... Volumetric magnetic resonance imaging analyses of 30 subjects were undertaken to quantify the global and temporal lobe atrophy in semantic dementia and Alzheimer's disease. This is further compounded by the use of outcome measures in clinical trials not directly related to the mechanism of action of the medication under study.

An outstanding issue in graph-theoretical studies of brain functional connectivity is the lack of formal criteria for choosing parcellation granularity and correlation threshold.

Graph theory-based analyses of brain network topology can be used to model the spatiotemporal correlations in neural activity detected through fMRI, and such approaches have wide-ranging potential, from detection of alterations in preclinical Alzheimer's disease through to command identification in brain-machine interfaces. Dr Dennis Chan Department of Clinical Neurosciences. Serial registered MRI provides a reproducible technique for detecting progressive cerebral atrophy in vivo and was used to determine if there were differences between the rates of cerebral atrophy in AD and frontotemporal dementia (FTD). There is an increasing global research effort into strategies for early clinic-based diagnosis at the stage where patients present with mild memory problems. Dr Chan lives in West Sussex with his wife and two children. Hasok Chang . Regional and global cerebral atrophy are inevitable features of Alzheimer's disease (AD). chandlerhl1@cardiff.ac.uk. Appointments. In this study, we examined whether these synaesthetes show a generic associative memory advantage for stimuli that do not elicit a synaesthetic colour. The hippocampus is one of the first regions to exhibit neurodegeneration in Alzheimer’s disease (AD), and knowledge of its role in allocentric spatial memory may therefore aid early diagnosis of AD. EEG abnormalities were found in 61% of FTLD patients, with the degree of EEG abnormality increasing with dementia severity. Magnetic resonance imaging reveals abnormal signal predominantly restricted to the mediotemporal lobes. Dr Hannah Chandler. In the 24-month MS-STAT phase 2 trial, we showed that high-dose simvastatin significantly reduced the annualised rate of whole brain atrophy in patients with secondary progressive multiple sclerosis (SPMS). ProceedingsonPrivacyEnhancingTechnologies;2018(3):5–21 Dionysis Manousakas*, Cecilia Mascolo, Alastair R. Beresford, Dennis Chan, and Nikhil Sharma In collaboration with Professor Neil Burgess at UCL, a team of scientists at the Department of Clinical Neurosciences at the University of Cambridge led by Dr Dennis Chan, previously Professor O'Keefe's PhD student, developed and trialled a VR navigation test in patients at risk of developing dementia. He is the clinical academic lead for research into early Alzheimer's disease (AD). His specialist registrar training in Neurology was undertaken within the West London Deanery, with rotations through Atkinson Morley’s Hospital, St Mary’s Hospital, the National Hospital for Neurology and Neurosurgery at Queen Square, and Charing Cross Hospital. Polymorphisms in the apolipoprotein E (APOE) gene have been associated with individual differences in cognition, brain structure and brain function.

His private clinics are located at Spire Gatwick Park Hospital, Spire Montefiore Hospital in Hove and The North Downs Hospital in Caterham.

In AD, ROI analyses appear more sensitive to volume loss in the amygdalae, wh... Damage limited to the hippocampus is believed to result in temporally graded retrograde amnesia (RA), with more severe RA occurring only as a result of additional damage to adjacent neocortical structures.

This PhD involved studying the connections of the hippocampus, a region of the brain crucial for memory and navigation, and which is affected in the earliest stages of Alzheimer’s disease (AD). Here, we aimed to explore whether simvastatin effects on brain atrophy and disability in secondary progressive multiple sclerosis (SPMS) are mediated by reducing cholesterol or are independent of cholesterol. For example, the ε4 allele has been associated with cognitive and brain impairment in old age and increased risk of dementia, while the ε2 allele has been claimed to be neuroprotective.
