The discussion of that big Vytorin study at this weekend’s big cardiology meeting was harsher than expected. Industry observers had predicted that an open conversation by the experts could temper the negative image of the drug that emerged earlier this year after the study results were made public, but just the opposite occurred.
The study was presented at the conference yesterday and published online in the New England Journal of Medicine.
“You’ve just seen a negative trial that should change practice, especially the way we in this country have prescribed,” Harlan Krumholz of Yale told thousands of cardiologists at the meeting, the WSJ reports.
The NEJM also published an editorial based on the study results, calling on doctors to prescribe Zetia (and, by extension, Vytorin), only in selected cases.
Catherine Arnold of Credit Suisse called the discussion “surprisingly negative,”

Alzheimer's: Understand and control wandering
Find out why people with Alzheimer's wander and what you can do to keep them safe.
Alzheimer's disease can erase a person's memory of once-familiar surroundings and make adaptation to new surroundings extremely difficult. As a result, people with Alzheimer's sometimes wander away from their homes or care centers and turn up — frightened and disoriented — far from where they started, long after they disappeared.
This is an interesting and thought provoking article that highlights the problems of Alzheimer's caregivers.

Three In Five Caregivers Say Their Children Help Care For Loved Ones With Alzheimer's Disease
Results from the third annual Alzheimer’s Foundation of America (AFA) ICAN: Investigating Caregivers’ Attitudes and Needs Survey suggest that Alzheimer’s disease care is a family affair. Most “sandwich caregivers” – the parents or guardians of children under 21 who also care for an aging parent, other relative or friend with Alzheimer’s disease – say their children are assisting with caregiving responsibilities that range from attending doctors’ appointments to feeding and dressing their loved ones.

We use to pay over $100 a month for Zocor. The generic now runs $10 a month (since July 2007).
Drug developer Teva Pharmaceutical Industries Ltd. said Friday a U.S. District Court ordered Teva to tentatively refrain from selling a generic version of Eisai Co.'s Alzheimer's treatment Aricept.
The tentative injunction by the U.S. District Court for the District of New Jersey was requested by Japan's Eisai as part of an ongoing lawsuit with Teva.
Teva has already gained tentative Food and and Drug Administration approval for the generic drug and could receive final approval April 26, when the mandatory stay of approval under the patent lawsuit expires. A trial date has not yet been set.

Study Finds Improved Cognitive Health among Older Americans
Rates of cognitive impairment among older Americans are on the decline, according to a new study supported by the National Institutes of Health (NIH) comparing the cognitive health of older people in 1993 and 2002. Higher levels of education were associated with better cognitive health.
Alzheimer's disease is a physical illness that causes radical changes in the brain. As healthy brain tissues degenerate persons suffering from Alzheimer's experience a steady decline in memory and the ability to use their brain to perform tasks.
Alzheimer's disease is the most common form of dementia.

What is it?
Dementia is the gradual deterioration of mental functioning, such as concentration, memory, and judgment, which affects a person’s ability to perform normal daily activities.
Who gets it?
Dementia occurs primarily in people who are over the age of 65, or in those with an injury or disease that affects brain function. While dementia is most commonly seen in the elderly, it is not a normal consequence of the aging process.
What causes it?
Dementia is caused by the death of brain cells. Brain cells can be destroyed by brain diseases, such as Alzheimer’s disease, or strokes (called vascular or multi-infarct dementia), which decrease blood flow to the brain. Lewy body dementia is another common cause attributed to changes in brain tissue. Other causes can include AIDS, high fever, dehydration, hydrocephalus, systemic lupus erythematosus, Lyme disease, long-term drug or alcohol abuse, vitamin deficiencies/poor nutrition, hypothyroidism or hypercalcemia, multiple sclerosis, brain tumor, or diseases such as Pick’s, Parkinson's, Creutzfeldt-Jakob, or Huntington's. Dementia can also result from a head injury that causes hemorrhaging in the brain or a reaction to a medication.
What are the symptoms?
In most cases, the symptoms of dementia occur gradually, over a period of years. Symptoms of dementia caused by injury or stroke occur more abruptly. Difficulties often begin with memory, progressing from simple forgetfulness to the inability to remember directions, recent events, and familiar faces and names. Other symptoms include difficulty with spoken communication, personality changes, problems with abstract thinking, poor personal hygiene, trouble sleeping, and poor judgment and decision making. Dementia is extremely frustrating for the patient, especially in the early stages when he or she is aware of the deficiencies it causes. People with dementia are likely to lash out at those around them, either out of frustration or because their difficulty with understanding makes them misinterpret the actions of others. They become extremely confused and anxious when in unfamiliar surroundings or with any change in routine. They may begin a task, such as cooking, then wander away aimlessly and completely forget what they had been doing. Dementia is often accompanied by depression and delirium, which is characterized by an inability to pay attention, fluctuating consciousness, hallucinations, paranoia, and delusions. People in advanced stages of dementia lose all control of bodily functions and are completely dependent upon others.
How is it diagnosed?
Dementia is diagnosed through a study of the patient’s medical history and a complete physical and neurological exam. The doctor will speak with those close to the patient to document a pattern of behavior. He or she will also evaluate the patient’s mental functioning with tests of mental status, such as those that require the patient to recall words, lists of objects, names of objects, and recent events. Diagnostic tests, such as blood tests, x-rays, or magnetic resonance imaging (MRI), positron emission tomography (PET), or computed tomography (CT) scans, can help determine the cause of the dementia.
What is the treatment?
In some instances, treating the cause of dementia may successfully reverse some or all of the symptoms. This is the case when the cause is related to a vitamin/nutritional deficiency, tumor, alcohol or drug abuse, reaction to a medication, or hormonal disorder. When dementia is related to an irreversible destruction of brain tissue, such as with Alzheimer’s disease, Lewy body dementia, or multiple strokes, treatment involves improving the patient’s quality of life as much as possible. This includes maintaining a stable, safe, supportive environment and providing constant supervision. While this may be done in the home, people in the advanced stages of dementia may require round-the-clock care in a long-term healthcare facility. It is important to provide the patient with structured activities and avoid disruptions to his or her daily routine. Many patients enjoy therapeutic activities, such as crafts or games, designed specifically for people with dementia. Some medications, such as donepezil and tacrine, have been effective in improving the mental functions of those in the beginning stages of dementia. Patients with hallucinations and delusions may also be treated with antipsychotic drugs, while antidepressant medications are used to treat depression.
There is currently no known way to prevent dementia associated with Alzheimer's disease. You can decrease your risk of dementia associated with stroke by maintaining a healthy lifestyle, following a heart-healthy diet, and controlling high blood pressure and high cholesterol. Healthy lifestyles, including not smoking and not abusing drugs and alcohol, go a long way in keeping most people in good health. Caring for a person with dementia is stressful. It is important to learn all you can about the disease, seek the help of support groups, and find a responsible caregiver who can give you a break when needed. There are daycare programs specifically designed for patients with dementia that are good for the patient and the family.

The 36-Hour Day: A Family Guide to Caring for People with Alzheimer Disease and Memory Loss in Later Life
Memory loss and thinking problems are becoming less common among older Americans, according to a new national survey of seniors aged 70 and older. Though preliminary, the findings correlate with other studies showing that overall, seniors today tend to be more physically fit and suffer from less disability than earlier generations. Still, with the population as a whole growing older, millions of Americans will continue to suffer from Alzheimer’s disease and related disorders in the coming years, making Alzheimer’s a top priority for this and future generations.
the researchers, from the University of Michigan Health Center, found than over a 10-year period, from 1993 to 2002, the prevalence of mental impairment in seniors went down by 3.5 percentage points — from 12.2 percent to 8.7 percent, in a sample of some 11,000 people. The difference represents hundreds of thousands of people.
seniors with more formal education and personal wealth were less likely to have cognitive problems
Having a large belly in middle age nearly triples the risk of developing dementia.
Researchers measured the abdominal fat of 6,583 people age 40 to 45 in northern California and some 36 years later 16 percent had developed dementia.
Those who were overweight or obese but did not have a pot belly had an 80 percent increase in the risk of dementia compared to people with a normal body weight and abdominal fat level.
The risk increase jumped to 230 percent among overweight people with a large belly and 360 percent among the obese with large abdomens.
"Where one carries the weight -- especially in midlife -- appears to be an important predictor for dementia risk," Whitmer said.
"These findings imply that the dangerous effects of abdominal obesity on the brain may start long before the signs of dementia appear."

"We have plenty of epidemiological evidence connecting activity, exercise and education with later onset of Alzheimer's, but it has never been clear which came first...Did the active lifestyle delay disease, or was there something inherent in a disease-resistant brain that led to a mentally and physically active lifestyle?"
Enriched environment delays onset of Alzheimer's in mice
A research group based at the University of Chicago has found that an enriched environment -- in this case more chances to exercise, explore and interact with others -- can dramatically reduce the biological hallmarks of Alzheimer's disease in mice that are genetically predisposed to the disorder.
In the 11 March 2005 issue of Cell, the researchers show that mice raised in a deluxe setting – large cages filled with running wheels, colored tunnels and multiple toys -- had much less of the beta-amyloid peptides that are characteristic of Alzheimer's disease deposited in their brains than genetically similar mice raised in a standard environment. Mice from enriched settings also had more of an enzyme that breaks down amyloid as well as increased activity of several genes involved in learning and memory, brain cell survival and the growth of new blood vessels.
"We have plenty of epidemiological evidence connecting activity, exercise and education with later onset of Alzheimer's, but it has never been clear which came first," said study-author Sangram Sisodia, PhD, professor of neurobiology, pharmacology and physiology at the University of Chicago. "Did the active lifestyle delay disease, or was there something inherent in a disease-resistant brain that led to a mentally and physically active lifestyle?"
"This is the first demonstration," he said, "in a genetically clean, carefully controlled animal model showing that an enhanced environment can have such a tremendously beneficial impact, protecting the brain from the pathological hallmarks of this insidious disease."
These findings support a "potentially causal inverse relationship between a more engaging, enriched life and AD progression," note Stanislav Karsten and Daniel Geschwind of UCLA in an accompanying editorial. They also provide "clear initial directions for exploring the role of the environment and the molecular pathways perturbed in AD and other neurodegenerative disorders."
Sisodia, and colleagues from his lab -- Orly Lazarov, PhD, assistant professor of neurobiology, pharmacology & physiology and lead author of the study, and John Robinson, senior research technician -- studied mice carrying two mutated genes (amyloid precursor protein and presenilin-1) that predispose the animals to develop Alzheimer's disease early in life.
At one month of age, nine of these mice were placed in the enriched environment and seven in standard housing. After five months, the researchers began to search for the pathological signs of AD in the mice's brains.
They found that mice from the enriched environment had a dramatic reduction of amyloid deposits in their brains, including less than half the volume of amyloid deposits in the hippocampus and cortex, regions involved in memory and reasoning.
The researchers also looked for genes that were activated at different levels in brains of mice from enriched versus standard housing. They identified 41 such genes, many of them already known to protect nerve cells. One of them was the gene for an enzyme that degrades beta-amyloid called neprilysin, which was at significantly higher levels in mice from the enhanced setting.
These mice also showed greater activity for several other genes involved in memory and learning, the growth of new nerve cells, cell survival, and the growth of new blood vessels within the brain.
The researchers also noted one "personality" difference among the mice in the enriched environment that influenced amyloid levels. Some of these mice were extremely active, frequently exploring their cages or running on the wheel. Others, the couch-potato mice, had the same opportunities for exercise but chose much less activity.
The most active mice had the least beta-amyloid. Less active mice from the enriched environment had more and those from the standard housing, who got the least exercise, had the most.
A lot of the process involves simple plumbing, Sisodia suspects, delivering blood to the brain and carrying harmful substances away. "It may be all about blood flow," he suggested. Exercise and mental activity can stimulate growth of new vessels while they help keep existing vessels in the brain open and functional, just like in the heart.
"Whenever we find amyloid deposits in the brain we also see them in the vessels," he said. "We suspect a large part of this process is the growing inability of mice, or people, who are developing Alzheimer's to get rid of the substances that comprise amyloid deposits, to slice up the peptides, sweep them into the blood stream and ship them out of the brain."
The take home message for humans, he said, is use it or lose it. "Activity helps, physical activity helps and mental activity helps," he said, "and the earlier you begin the better, a troubling notion in an increasingly inactive society. This is prevention, not therapy."
About 4.5 million people in the United States have Alzheimer's disease, including about five percent of those aged 65 to 74. Risk increases with age.

Alzheimer’s disease is the most common cause of dementia.
This section provides information about the definition of dementia, the characteristics of specific types of dementia and the symptoms, risk factors for and treatment of Alzheimer’s disease.
Dementia: Definition and Specific Types
Dementia is a clinical syndrome of loss or decline in memory and other cognitive abilities. It is caused by various diseases and conditions that result in damaged brain cells. To be classified as dementia, the syndrome must meet the following criteria:
• It must include decline in memory and in at least one of the following cognitive abilities:
1. Ability to generate coherent speech and understand spoken or written language;
2. Ability to recognize or identify objects, assuming intact sensory function;
3. Ability to execute motor activities, assuming intact motor abilities, sensory function and comprehension
of the required task; and
4. Ability to think abstractly, make sound judgments and plan and carry out complex tasks.
