Emerging importance of computerized cognitive testing -- new therapies for dementia
Date:7/18/2013

Boston, MA Computerized cognitive testing is increasingly playing a key role in therapy development for dementia and Alzheimer's disease. This week at the Alzheimer's Association International Conference, Keith Wesnes Ph.D., Practice Leader of Bracket and founder of the CDR System, discussed new data for novel therapies at two poster presentations at the Alzheimer's Association International Conference.

Poster Title: Cognitive evidence in Alzheimer's disease patients that compromised hippocampal neurogenesis is related both to APOE4 status and CSF Abeta42

This presentation provides the first behavioural data in Alzheimer's patients which associates genetic and biomarker activity to dysfunction in a major brain area involved both in memory and the production of new nerve cells (neurogenesis), This exciting finding obtained in collaboration with a group including Kaj Blennow, University of Gothenburg, found that patients with two APOE ϵ4 alleles (which confer a 10 to 30 fold increased risk of developing Alzheimer's disease) showed a selective decline in a computerised cognitive test measure associated with activity in the hippocampal dentate gyrus. Furthermore, in all patients studied, this test measure was more closely associated with the levels of the Aβ42 biomarker for the disease than a number of other memory measures associated with different hippocampal regions.

As interest in Alzheimer's research is shifting to begin treating the disease at its earliest stages, these findings identify a potential genetic and biomarker strategy for selecting individuals for early treatment with therapies which may promote hippocampal neurogenesis.

Poster Title: Memantine improves attention and verbal episodic memory in Parkinson's disease dementia and dementia with Lewy bodies: a double-blind placebo-controlled multicentre trial

A second presentation provides the first data that performance on objective tests of attention a
