Mayo Clinic study finds mild cognitive impairment is more common in men
2010-09-07
(Press-News.org) ROCHESTER, Minn. -- A new Mayo Clinic study found that the prevalence of mild cognitive impairment was 1.5 times higher in men than in women. The research, part of the Mayo Clinic Study of Aging, also showed a prevalence rate of 16 percent in the population-based study of individuals aged 70-89 without dementia who live in Olmsted County, Minn. The study will be published in the September issue of Neurology.
"The finding that the frequency of mild cognitive impairment is greater in men was unexpected, since the frequency of Alzheimer's disease is actually greater in women. It warrants further study," says Ronald Petersen, M.D., Ph.D., neurologist and director of the Mayo Clinic Alzheimer's Disease Research Center. "If we consider the 16 percent prevalence of mild cognitive impairment in individuals without dementia, then add the 10-11 percent of individuals who already have dementia or Alzheimer's disease, we're looking at 25 percent or more of the population aged 70 or older who have dementia or are at risk of developing dementia in the near future. With the aging of America, these numbers are staggering and the impact on the health care economy, as well as on individuals and their families, is quite impressive. The need for early diagnosis and therapeutic intervention is increasingly important."

A surface molecule on bacteria that instructs bone cells to die could be the target for new treatments for bone disease, says a scientist speaking at the Society for General Microbiology's autumn meeting today.
Blocking the death signal from bacteria could be a way of treating painful bone infections that are resistant to antibiotics, such as those caused by Meticillin-resistant Staphylococcus aureus (MRSA).
Bone disease, or osteomyelitis, affects 1 in 5,000 people around the world. It can occur at any stage in life and attack any bone in the body, where it leads to ...

Cockroaches could be more of a health benefit than a health hazard according to scientists from the University of Nottingham, who have discovered powerful antibiotic properties in the brains of cockroaches and locusts.
Simon Lee, a postgraduate researcher who is presenting his work at the Society for General Microbiology's autumn meeting in Nottingham, describes how the group identified up to nine different molecules in the insect tissues that were toxic to bacteria. These substances could lead to novel treatments for multi-drug resistant bacterial infections.
The group ...

Coughing and wheezing patients could someday benefit from quicker, more accurate diagnosis and treatment for respiratory infections such as flu, through a simple blood test, according to scientists.
Dr. Aimee Zaas, presenting her work at the Society for General Microbiology's autumn meeting in Nottingham describes how simply looking at an individuals blood 'signature' can be used to quickly diagnose and treat ill patients and could even predict the onset of a pandemic.

LOS ANGELES (Sept. 6, 2010) – In the first human study of its kind to be published in more than 35 years, researchers found psilocybin, an hallucinogen which occurs naturally in "magic mushrooms," can safely improve the moods of patients with advanced-stage cancer and anxiety, according to an article published online today in the Archives of General Psychiatry.
Patients enrolled in the study at the Los Angeles Biomedical Research Institute at Harbor-UCLA Medical Center (LA BioMed) demonstrated improvement of mood and reduction of anxiety up to six months after undergoing ...

Risky sexual behavior among members of a subset of the gay community is still adding to the spread of HIV. Research published in the open access journal BMC Infectious Diseases has found that young white homosexual men have an important contribution in the local spread of HIV.
Despite increased education and awareness of HIV in the Western world, the number of new infections continues to rise each year. To try and understand this phenomenon, researchers from Ghent University in Belgium compared the genetic information of viruses isolated from more than 500 patients – ...

A fixation on geometric patterns may be associated with autism in children as young as 14 months, according to a report published online today that will appear in the January 2011 print issue of Archives of General Psychiatry, one of the JAMA/Archives journals.
"It is undeniable that early treatment can have a significant positive impact on the long-term outcome for children with an autism spectrum disorder," the authors write as background information in the article. "Early treatment, however, generally relies on the age at which a diagnosis can be made, thus pushing ...

A pilot study suggests the hallucinogen psilocybin may be feasible and safe to administer to patients with advanced-stage cancer and anxiety, with promising effects on mood, according to a report published online today that will appear in the January 2011 print issue of Archives of General Psychiatry, one of the JAMA/Archives journals.
"In recent years, there has been a growing awareness that the psychological, spiritual and existential crises often encountered by patients with cancer and their families need to be addressed more vigorously," the authors write as background ...

The association between psychotic disorders and living in urban areas appears to be a reflection of increased social fragmentation present within cities, according to a report in the September issue of Archives of General Psychiatry, one of the JAMA/Archives journals.
"There is a substantial worldwide variation in incidence rates of schizophrenia," the authors write as background in the article. "The clearest geographic pattern within this distribution of rates is that urban areas have a higher incidence of schizophrenia than rural areas." Characteristics of neighborhoods ...

Patients with early-stage schizophrenia who receive a combination of medication and a psychosocial intervention appear less likely to discontinue treatment or relapse—and may have improved insight, quality of life and social functioning—than those taking medication alone, according to a report in the September issue of Archives of General Psychiatry, one of the JAMA/Archives journals.
Antipsychotic drugs are the mainstay of therapy for patients with schizophrenia, but long-term therapy is associated with adverse effects and poor adherence, according to background information ...
