A large study of patients with mild cognitive impairment revealed that results from cognitive tests and brain scans can work as an early warning system for the subsequent development of Alzheimer's disease.

Eye Tracking Can Detect Mild Dementia In Humans

Researchers at the Yerkes National Primate Research Center, Emory University, developed a test in nonhuman primates that is now using infrared eye tracking to detect mild cognitive impairment (MCI) in humans.

MRI shows brain atrophy pattern that predicts Alzheimer's

Using special MRI methods, researchers have identified a pattern of regional brain atrophy in patients with mild cognitive impairment (MCI) that indicates a greater likelihood of progression to Alzheimer's disease. The findings are published in the online edition of Radiology.

Heart failure linked to cognitive impairment

Nearly half of patients with heart failure (HF) have problems with memory and other aspects of cognitive functioning, reports a new study published by Elsevier, in the February issue of Journal of Cardiac Failure.

Study suggests reliability of cognitive assessment tool varies widely

A study published in the November issue of the Journal of Alzheimer's Disease (Volume 15:3) suggests the reliability of the Alzheimer's Disease Assessment Scale – Cognitive (ADAS-Cog) may vary and possess the ability to affect clinical trial outcomes.

Chronic exposure to estrogen impairs some cognitive functions

University of Illinois researchers report this week that chronic exposure to estradiol, the main estrogen in the body, diminishes some cognitive functions. Rats exposed to a steady dose of estradiol were impaired on tasks involving working memory and response inhibition, the researchers found.

How older adults function in daily life

As more adults age into the high-risk period for cognitive impairment, clinicians need simple and reliable methods to identify where they may have problems in everyday life that reveal underlying changes in the brain.

Gene may shed light on neurological disorders

harminka — Fri, 23 May 2008 05:35:26 -0500

In our brains, where millions of signals move across a network of neurons like runners in a relay race, all the critical baton passes take place at synapses. These small gaps between nerve cell endings have to be just the right size for messages to transmit properly. Synapses that grow too large or too small are associated with motor and cognitive impairment, learning and memory difficulties, and other neurological disorders.

Total sleep time in older people with cognitive impairment, sleep disturbance

harminka — Fri, 01 Feb 2008 06:49:39 -0600

A higher periodic leg movement index (PLMI) predicted less sleep at night in older people with cognitive impairment and sleep disturbance, according to a study published in the February 1 issue of the journal SLEEP.

High blood pressure associated with risk for mild cognitive impairment

High blood pressure appears to be associated with an increased risk for mild cognitive impairment, a condition that involves difficulties with thinking and learning, according to a report in the December issue of Archives of Neurology, one of the JAMA/Archives journals.

Innovative 3D-imaging technique captures brain damage linked to Alzheimer's disease

Alzheimer's patients have significantly more cortical damage than those with mild cognitive impairment

First study of cognitive impairment due to chronic Lyme disease

harminka — Thu, 11 Oct 2007 10:12:17 -0500

Findings from the first placebo-controlled study of chronic cognitive impairment after treated Lyme disease (also known as chronic Lyme encephalopathy) demonstrate that patients report moderate cognitive impairment, physical dysfunction comparable to patients with congestive heart failure, and fatigue comparable to patients with multiple sclerosis.
