Nutrient ‘Cocktail’ Appears to Improve Dementia Symptoms

FRIDAY, Jan. 8 (HealthDay News) — A combination of three nutrients might help improve memory in Alzheimer’s patients by stimulating the growth of new brain connections (synapses), a new study shows.

Uridine, choline and the omega-3 fatty acid DHA (all found in breast milk) are precursors to the fatty molecules that make up brain cell membranes, which form synapses.

“If you can increase the number of synapses by enhancing their production, you might to some extent avoid that loss of cognitive ability” that occurs in Alzheimer’s patients, Richard Wurtman, a professor of brain and cognitive sciences at MIT, said in a news release. He conducted the basic research that led to this investigational treatment.

In a clinical trial, 225 Alzheimer’s patients were given a cocktail of the three nutrients, along with B vitamins, phosopholipids and antioxidants. Patients with mild Alzheimer’s showed improvements in verbal memory.

The study was published Jan. 8 in the journal Alzheimer’s and Dementia.

Three additional clinical trials are underway in the United States and Europe. Results are expected within a few years.

CDC – What are the symptoms of swine flu (H1N1)?

Although uncomplicated influenza-like illness (fever, cough or sore throat) has been reported in many cases, mild respiratory illness (nasal congestion, rhinorrhea) without fever and occasional severe disease also has been reported. Other symptoms reported with swine influenza A virus infection include vomiting, diarrhea, myalgia, headache, chills, fatigue, and dyspnea. Conjunctivitis is rare, but has been reported. Severe disease (pneumonia, respiratory failure) and fatal outcomes have been reported with swine influenza A virus infection. The potential for exacerbation of underlying chronic medical conditions or invasive bacterial infection with swine influenza A virus infection should be considered.

What are the symptoms of swine flu (H1N1)?

Symptoms of swine flu are similar to most influenza infections: fever (100F or greater), cough, nasal secretions, fatigue, and headache, with fatigue being reported in most infected individuals. Some patients also get nausea, vomiting, and diarrhea. In Mexico, many of the patients are young adults, which made some investigators speculate that a strong immune response may cause some collateral tissue damage. Some patients develop severe respiratory symptoms and need respiratory support (such as a ventilator to breathe for the patient). Patients can get pneumonia (bacterial secondary infection) if the viral infection persists, and some can develop seizures. Death often occurs from secondary bacterial infection of the lungs; appropriate antibiotics need to be used in these patients. The usual mortality (death) rate for typical influenza A is about 0.1%, while the 1918 “Spanish flu” epidemic had an estimated mortality rate ranging from 2%-20%. Swine flu in Mexico (as of April 2009) has had about 160 deaths and about 2,500 confirmed cases, which would correspond to a mortality rate of about 6%, but these initial data have been revised and the mortality rate currently in Mexico is estimated to be much lower. By June 2009, the virus had reached 74 different countries on every continent except Antarctica, and by September 2009, the virus had been reported in most countries in the world. Fortunately, the mortality rate as of October 2009 has been low but higher than for the conventional flu (average conventional flu mortality rate is about 36,000 per year; projected novel H1N1 flu mortality rate is 90,000 per year in the U.S. as determined by the president’s advisory committee).
