A recent study says that changes in cerebrospinal fluid levels can help predict risk of Alzheimer's disease (AD).
They found that cerebrospinal fluid levels of AB42 appear to be decreased at least five to 10 years before some patients with mild cognitive impairment develop AD dementia whereas other spinal fluid levels seem to be later markers of disease.
Alzheimers Disease
Alzheimer''s disease is a progressive neurodegenerative disease affecting memory and thinking and making the person increasingly dependent on others.

The researchers suggested that disease-modifying therapies, such as immunotherapy, are more likely to be successful if started in the early stages of the disease.
Peder Buchhave, M.D., Ph.D, who is affiliated with Lund University and Skane University, Sweden, and colleagues conducted an extended follow-up of the cohort from a previous study of 137 patients with mild cognitive impairment (MCI) at baseline. The median follow-up was 9.2 years.

Alzheimer's disease (AD) is the most common form of dementia. Participate in this quiz to find out how much you know about this debilitating disease.
During the follow-up, 72 patients developed AD and 21 progressed to other forms of dementia.
At the baseline, cerebrospinal fluid AB42 levels were reduced and other biomarkers T-tau and P-tau levels were elevated in patients who converted to AD during follow-up compared with levels in patients who did not develop AD.
The study indicates baseline CSF AB42 levels were equally reduced in patients with MCI who converted to AD within five years (the early converters) compared to those who converted later between five and 10 years. However, T-tau and P-tau levels were significantly higher in early converters compared to later ones.
Researchers suggest "approximately 90 percent of patients with MCI and pathologic CSF biomarkers at baseline will develop AD within 9.2 years."
"Therefore, these markers can identify individuals at high risk for future AD least five to 10 years before conversion to dementia," the researchers stated.
"Hopefully, new therapies that can retard or even halt progression of the disease will soon be available. Together with an early and accurate diagnosis, such therapies could be initiated before neuronal degeneration is too widespread and patients are already demented," they concluded.
The findings appeared in the January issue of Archives of General Psychiatry, one of the JAMA/Archives journals.
