This book aims to identify and measure cognitive and social abilities in
people with dementia and also in people with additional learning
disabilities. Definitions of dementia are discussed in detail, outlining
the neuropathology, neuropsychology and clinical signs of Alzheimer's
disease, and the neuropsychology of multi-infarct dementia. Discussion
is made of the difficulties of a differential diagnosis and also the
difficulties in assessing learning disability and dementia. A critique
of instruments used in the clinical studies includes details of their
reliability, validity, and standard error and norms of each tool.
Empirical studies are presented together with the design and development
of a neuropsychological test battery for the clinical assessment of
people with dementia and learning disability. A link between cognitive
performance and social abilities is presented for people with Down's
syndrome and dementia that highlights failure in the Central Executive
System and Articulatory Loop System, important in normal memory.
Emphasis is made on the need to improve and widen access in service
provision for these valued people.
