Functional imaging methods used in research on aging, mild cognitive impairment, and dementia of the Alzheimer type include single-photon emission computed tomography (SPECT),  positron emission tomography (PET),  and functional magnetic resonance imaging (fMRI). Positron emission tomography and single-photon emission computed tomography use radioisotope tracers to detect brain metabolism or blood flow. Functional magnetic…    



Clinical Conclusions

Using an evidence-based review of the literature, the Quality Standards Subcommittee of the American Academy of Neurology made three levels of recommendation for clinical practice related to the diagnosis and evaluation of individuals with mild cognitive impairment and dementia (Knopman et al. 2001; Petersen et al. 2001): standards were based on patient management…    



Test Combination Helps Predict Alzheimer’s Disease Risk

With age, forgetfulness and other signs of memory loss sometimes appear, prompting elderly individuals to seek a medical evaluation amid fears that they may be experiencing early symptoms of Alzheimer’s disease (AD), the most common type of dementia among Americans aged 65 and older.

But even when early memory problems suggest the potential for…    



Hypertension affects brain capacity

Can dementias and mild cognitive impairment be influenced in their course by diseases and risk factors? This is the subject of a study reported by Thorleif Etgen and co-authors in the current issue of Deutsches Ärzteblatt International (Dtsch Arztebl Int 2011; 108[44]: 743-50).

Increasingly larger numbers of people are affected by mild cognitive impairments…    



Eating fish reduces risk of Alzheimer’s disease

People who eat baked or broiled fish on a weekly basis may be improving their brain health and reducing their risk of developing mild cognitive impairment (MCI) and Alzheimer’s disease, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA).

“This is the first study to…    



Overeating can double the risk of memory loss

A new US study has found that people who eat too much in their seventies or older are doubling their risk of memory impairment, or mild cognitive impairment (MCI), which can be an early sign of Alzheimer’s disease.

The study Daily Caloric Intake, Aging and Mild Cognitive Impairment by Yonas E Geda, associate professor…
