Exercise slows decline in Alzheimer's patients

I can attest, exercise makes a difference. My mother now has the tendency to sit around all day. On those days when I can get her to go to Gold's Gym with me she is a completely different person. The look on her face, from dull to smiling, is more than enough to tell me that exercise works to her benefit.

"Nursing home residents with Alzheimer's disease who participate in a moderate exercise program have a significantly slower deterioration than those who receive routine medical care, researchers have shown."

Loneliness and Alzheimer's Linked

People who are lonely are twice as likely to develop Alzheimer's disease, a large US study has suggested.

Source Archives of General Psychiatry

A total of 823 older persons free of dementia at enrollment were recruited from senior citizen facilities in and around Chicago, Ill. Loneliness was assessed with a 5-item scale at baseline (mean ± SD, 2.3 ± 0.6) and annually thereafter. At death, a uniform postmortem examination of the brain was conducted to quantify AD pathology in multiple brain regions and the presence of cerebral infarctions.

The study found that the risk of Alzheimer's disease was more than doubled in lonely persons compared with persons who were not lonely. The study also concluded that Loneliness is associated with an increased risk of late-life dementia but not with its leading causes.

Huperzine A in Alzheimer's Disease--Phase Two Clinical Trial

The Huperzine A in Alzheimer's Disease clinical trial is currently open and recruiting patients. This is a Phase II clinical trial.



Huperzine A in Alzheimer's Disease-The Clinical Trial

See the trial specification at Clinical Trials.gov

Study Type: Interventional

Study Design: Treatment, Randomized, Double-Blind, Placebo Control, Parallel Assignment, Safety/Efficacy Study

Official Title: A Multi-Center, Double-Blind, Placebo-Controlled Therapeutic Trial to Determine Whether Natural Huperzine A Improves Cognitive Function

Further study details as provided by National Institute on Aging (NIA).

Huperzine A is a natural cholinesterase inhibitor derived from the Chinese herb Huperzia serrata. There is evidence that huperzine A may compare favorably in symptomatic efficacy to cholinesterase inhibitors currently in use. In addition, huperzine A has antioxidant and neuroprotective properties that suggest that it may be useful as a disease-modifying treatment for Alzheimer's disease (AD). The drug is currently available as a nutraceutical in this country, and is being used by some U.S. clinicians to treat AD. However, there have been no controlled clinical trials outside China assessing its toxicity and efficacy. The present study will evaluate huperzine A in the treatment of AD in a randomized controlled trial of its effect on cognitive function.

The primary aim of this multicenter, double-blind, placebo-controlled therapeutic Phase II trial is to determine whether treatment with huperzine A 200µg twice a day improves cognitive function in individuals with AD. Secondary aims of this study are to: a) determine whether treatment with huperzine A 400µg twice a day improves cognitive function in individuals with AD; b) determine the effect of huperzine A treatment on global clinical status, activities of daily living, and behavior in AD; c) evaluate the tolerability of huperzine A treatment at dosages of 200µg twice a day and 400µg twice a day in AD; and d) determine the relationship between blood cholinesterase activity and cognitive function in individuals with AD treated with huperzine A. A total of 150 participants will be randomly assigned to three groups of equal size. This will allow a comparison of huperzine A 200µg twice a day, huperzine A 400µg twice a day, and placebo. The primary outcome measures will be the change in score on the ADAScog at the 16 week visit. Secondary outcome measures include the ADCS clinical global impression of change (CGIC) (Schneider et al 1997) and activities of daily living (ADL) (Galasko et al 1997) scales, and the Neuropsychiatric Inventory (Cummings 1997). Volunteers must be able to participate in the study for 24 weeks and make 9 visits to the trial site.

At the end of the double-blind study, participants will be invited to continue huperzine A treatment for 6 months in an open-label extension phase. Participants will receive 200µg of huperzine A twice a day for six consecutive months, and will be assessed at 3-month intervals (months 6, 9, and 12, with month 6 assessments coinciding with the final visit of the double-blind phase).

Eligibility

Ages Eligible for Study: 55 Years and above, Genders Eligible for Study: Both CriteriaThe selection process is designed to allow enrollment of all people with AD who are likely to be testable at the conclusion of the study period, and who do not have concurrent medical conditions or medications that might influence cognitive testing or that would increase the risk of treatment. Women and members of minority groups are encouraged to volunteer.

Able to complete baseline assessments.
6 years of education, or work history sufficient to exclude mental retardation.
Able to ingest oral medication.
Stable doses of medications for 4 weeks prior to screening.
Physically acceptable for this study as confirmed by medical history, physical exam, neurological exam and clinical tests.


Exclusion Criteria:

History of active peptic ulcer disease within 1 year of screening.
Clinically significant cardiac arrhythmia.
Resting pulse less than 50.

Excluded Medications:

Use of cholinesterase inhibitors (galantamine, rivastigmine, donepezil, and tacrine) within 2 months of screening.
Regular use of narcotic analgesics (>2 doses per week) within 4 weeks of screening.

Alzheimer's Vaccine Patch Works in Mice

"The Alzheimer's vaccine being tested works by triggering the immune system to recognize and attack Ab -- a protein that abnormally builds up in the brains of Alzheimer's patients."

New Gene Linked to Alzheimer's

"It fits into what we believe is the main mechanism of Alzheimer's already," Gandy said. "This reinforces the idea that we're on the right track with therapies already in the pipeline, while also suggesting a totally new strategy that could be used to target entirely new classes of drugs."
