Dementia and cognitive decline

Keith Laws' research is focused on differences in the severity and rate of cognitive decline shown by men and women with Alzheimer’s Disease. Our work was the first to document – using meta-analysis as well as empirical studies – that the severity of cognitive decline amongst women with AD is much greater than in men (who appear to be at the same disease stage)

This area of research deals with the locus of naming impairment in dementia, and factors influencing visual recognition of objects.

Alzheimers brain

It seeks to contribute to knowledge concerning models of semantic and perceptual knowledge organisation.

Sex differences in the cognitive decline of people with Alzheimer's (Prof Laws, Prof Gale and Karen Irvine) – is there evidence of differential cognitive impairment and decline in men and women with Alzheimer's disease.

Day-to-day cognitive fluctuations and their relationship to cognitive impairment in Alzheimer's disease (Prof Laws and Veronica Gonzalez).

Early visual processing deficits in Alzheimers disease (Prof Laws, Prof Gale and Dr Adlington) – Adlington and colleagues developed the Hatfield Image Test (published by American Psychological Association).

They have been examining whether the amount of visual information (line drawings versus greyscale versus colour photographs) aids object recognition in people with Alzheimer's disease – and surprisingly found that less visual information is beneficial to people with dementia.

Category-specific object recognition deficits in Alzheimer's patients (Prof Laws, Prof Gale, Dr Adlington, Karen Irvine) Over the past 10 years, this group has published over 30 papers examining the highly-selective deficits for categories of information in dementia, culminating in a recent book (Category-Specificity: Evidence for Modularity of Mind).
