Alzheimer’s origins revealed in 3-D

May 13th, 2008 by Richard Brassaw

The origins of Alzheimer’s disease is thought to be the result of A-beta peptide (Alzheimer’s peptide) when it clumps together in the brain and forms long fibrils. Whether it is the protein clumps or the fibrils that kill brain neurons is still being debated.
Nikolaus Grigorieff, biophysicist, Brandeis University, along with researchers at Leibniz Institut, Jena, [...]

Why depression medication fails to work for some patients

May 12th, 2008 by Richard Brassaw

Depressed people are known to have fewer of the ‘feel-good’ receptors for serotonin.
Jon-Kar Zubieta, MD, PhD, University of Michigan, reports that depression is rooted in genetic and molecular factors and are unique for each individual. Using PET (positron emission tomography) scans, Zubieta studied patients who met the criteria for major depression, but had not yet [...]

Painkiller abuse less than 3% in chronic pain patients

May 10th, 2008 by Richard Brassaw

Strict government oversite of opioid medications force physicians to balance the needs of their patients with demands from the government for better control of opioid medications. Fifty years ago cancer patients were denied opioids for their pain because of possible addiction.
Srinivasa Raja, MD, professor of anesthesiology, Johns Hopkins University Medical School, reports that less than 3% [...]

Diabetic eye disease responds better to meds than laser treatment

May 9th, 2008 by Richard Brassaw

One of the complications from diabetes is blindness known as diabetic macular edema (DME). DME is characterized by swelling of the central portion of the retina (or macula) at the back of the eye. It is one of the most common causes of blindness, which occurs when fluid and protein deposits collect on or under [...]

Alzheimer’s risks differs by sex

May 8th, 2008 by Richard Brassaw

Men and women differ on their risk of developing Alzheimer’s disease.
French researchers studied nearly 7,000 people over 65 years from the general population of 3 French cities. None of the subjects had dementia, but 4 out of 10 had mild cognitive impairment at the onset of the study. At 2 and 4 years the participants [...]

Alzheimer’s - diabetes link found

May 7th, 2008 by Richard Brassaw

Why diabetic patients are more likely to develop Alzheimer’s disease has not been understood. Researchers believe they may have identified the diabetes - Alzheimer’s connection.
David R. Schubert, PhD, professor Cellular Neurobiology Laboratory, Salk Institute for Biological Studies, reports that blood vessels in the brain of young diabetic mice are damaged by the interaction of elevated blood [...]

Faster Dementia decline linked to incontinence medication

May 6th, 2008 by Richard Brassaw

Among nursing home residents the 2 most common medical conditions are dementia and urinary incontinence; often they coexist. The problem is that the drugs used to treat each condition are pharmacological opposites, which can reduce the effectiveness of one or both drugs.
Kaycee M. Sink, MD, MAS, Wake Forest University School of Medicine, and colleagues, studied [...]

Increased bone fractures with diabetes drugs

May 5th, 2008 by Richard Brassaw

A relatively new and effective class of oral antidiabetic agents, thiazolidinediones, have gained in popularity and widely used to treat diabetic patients with insulin resistance. Two of the more popular drugs from this class are prioglitazone and rosiglitazone, which account for 21% of oral diabetes medications prescribed in the United States and 5% of those [...]

Parkinson’s patients benefit from cell-based therapy

May 4th, 2008 by Richard Brassaw

Parkinson’s disease (PD) is a progressive brain disorder that affects motor skills, which worsen as the disease advances. It is thought that in the early stages of the disease the brain begins to reduce the amount of the neurotransmitter dopamine. The reduced amount of dopamine results in trembling in the hands, arms, legs, and jaw. [...]
