Background:
Acetylcholinesterase inhibitors are the first drugs to alter the devastating effects of Alzheimer disease. The next generation of drugs will prevent the beta-amyloid plaques and neurofibrillary tangles or block enzymes that lead to neuron destruction. Effective use of these medications will require early identification of patients at risk.
Methods:
Using the PubMed service of the National Library of Medicine, all English language articles published in 2000, 2001 and the first half of 2002 with a key word of 'dementia' were reviewed for articles that described the emerging pathophysiologic model for Alzheimer disease.
Findings:
Standardized clinical screening tools, such as the mini-mental status examination and the clock test, administered longitudinally and correlated with family observations, can identify many at-risk patients. Genetic testing can identify a known mutation in 70% of patients who have a high family incidence of Alzheimer disease but awaits effective prevention before being useful. The molecular mechanisms of Alzheimer disease will eventually lead to prevention.
Conclusion:
Today, these patients benefit from nutritional support and lifestyle enhancement encouraged through a continuous primary care relationship.
Insights
Early identification of at-risk Alzheimer disease patients is crucial for future treatments. Clinical screening tools and genetic testing aid in identifying individuals who may benefit from upcoming preventative therapies.
Area of Science:
- Neurology
- Gerontology
- Pharmacology
Background:
- Alzheimer disease (AD) presents devastating effects, with current treatments like acetylcholinesterase inhibitors offering limited alteration.
- Next-generation AD therapies aim to prevent beta-amyloid plaques, neurofibrillary tangles, and neuron-destroying enzymes.
- Early identification of at-risk individuals is essential for the effective utilization of emerging AD medications.
Purpose of the Study:
- To review the emerging pathophysiologic model for Alzheimer disease.
- To identify methods for early detection of at-risk individuals for Alzheimer disease.
Main Methods:
- A comprehensive literature review was conducted using PubMed.
- English language articles published between 2000 and mid-2002 with the keyword 'dementia' were analyzed.
- Articles focusing on the pathophysiologic model of Alzheimer disease were specifically selected.
Main Results:
- Standardized clinical screening tools, including the mini-mental status examination and clock test, can identify at-risk patients when used longitudinally and correlated with family observations.
- Genetic testing identifies known mutations in 70% of familial Alzheimer disease cases but requires effective prevention strategies to be clinically useful.
- Understanding the molecular mechanisms of Alzheimer disease is key to developing future preventative treatments.
Conclusions:
- Currently, patients with Alzheimer disease benefit from nutritional support and lifestyle enhancements.
- Continuous primary care relationships are vital for encouraging these supportive measures.
