Clinical Trial: Omega 3 Fatty Acid, Slowing the Progression of Alzheimer's Disease

Preliminary studies have shown a reduced risk of Alzheimer's disease (AD) in people consuming increased amounts of fish in their diets. Many of the health benefits of fish are attributed to the abundance of omega 3 fatty acids. Docosahexaenoic Acid (DHA) is the most abundant omega 3 fatty acid in the brain. Data from several animal models supports the hypothesis that DHA may be an effective treatment for AD by means of anti-amyloid, antioxidant, and neuroprotectant mechanisms.

This study is currently recruiting patients.

Personal Note: I have been feeding my mother fish and giving her Omega 3 Oil daily for a couple of years. I believe it is beneficial.

Preliminary studies have shown a reduced risk of Alzheimer's disease (AD) in people consuming increased amounts of fish in their diets. Many of the health benefits of fish are attributed to the abundance of omega 3 fatty acids. Docosahexaenoic Acid (DHA) is the most abundant omega 3 fatty acid in the brain. Data from several animal models supports the hypothesis that DHA may be an effective treatment for AD by means of anti-amyloid, antioxidant, and neuroprotectant mechanisms.

In this study, 400 individuals with mild to moderate AD will participate at approximately 53 study sites throughout the US for 18 months. Participants will be randomized so that 60% will receive approximately 2 grams of DHA, divided into 4 capsules, 2 capsules taken twice a day, while 40% receive an identical placebo.

Potential participants will go to their study site for a screening visit, where eligibility is determined, and if accepted, for a baseline visit where cognitive status, behavioral status, functional status, and global severity of dementia will be assessed. Vital signs and biomarker labs will also be obtained. Subsequent visits will occur every three months for medication checks and, every 6 months, further assessments, physical exams, and labs.

Some participants will also take part in MRI (magnetic resonance imaging) and/or CSF (cerebrospinal fluid) sub-studies. For the MRI sub-study, scans will be done prior to beginning the study medication, and again after 18 months. Likewise, for the CSF sub-study, a lumbar puncture will be done prior to beginning the study medication, and again after 18 months.

Enrollment is restricted to individuals who consume no more than 200 mg of DHA per day, which is almost 300% of the average daily intake in an American diet. Individuals who take fish oil or omega 3 fatty acid supplements are also not eligible. Each visit will include completion of a very brief food frequency questionnaire to monitor dietary DHA levels.

The CareGiver: Alzheimer’s Disease--What is it?

Alzheimer's disease is the most common cause of a condition called dementia. It is named for the German doctor who first described it, Alois Alzheimer. What is it? Who gets it? What causes it?


The desciption below was taking from the Milton S. Hershey Medical Center website. This is useful to clear up some of the misunderstanding about the Alzherimer' Disease.

Alzheimer’s Disease


What is it?

Alzheimer's disease is the most common cause of a condition called dementia. Dementia is a general decline in mental ability, such as memory, language skills, judgment, and concentration. Alzheimer’s is a progressive disease, which means symptoms occur gradually and become worse over time. It is named for the German doctor who first described it, Alois Alzheimer.

Who gets it?

Alzheimer’s disease affects most commonly affects those over the age of 65, although it has been diagnosed in people in their 40s and 50s.


What causes it?

The degeneration of parts of the brain, which destroys brain cells, causes the symptoms of Alzheimer’s. However, at this time researchers are not sure what causes this degeneration. Those with a family history of Alzheimer’s are more likely to develop the disease as they age, so there is a gene abnormality that causes the disease in some people. Researchers are looking for links between Alzheimer’s disease and the environment, lifestyle, nutrition, and viruses.

What are the symptoms?

Alzheimer’s usually progresses in three stages, with each lasting anywhere from one to several years. The first symptom of Alzheimer’s disease is usually mild forgetfulness. Someone in the early stages may find him or herself unable to find the right word, recall where something was placed, or recall someone’s name. It may be difficult to concentrate. At this point, symptoms are so general that they do not signal a serious problem or have a great impact on day-to-day functioning. As the disease progresses to the second stage, the forgetfulness becomes worse, making it difficult to function at work, remember directions, or to even make it through the day without difficulty. The person may be restless and unable to sleep at night. His or her personality may change considerably, with increasing anxiety and decreasing emotions. By the late stages of Alzheimer’s, patients suffer from extreme confusion and memory loss. They are unable to recall the names of close friends and family or recent events, and cannot function socially or perform basic daily personal care. Late-stage Alzheimer’s patients may have hallucinations and delusions.

How is it diagnosed?

Alzheimer’s disease is diagnosed by taking a complete medical history and performing a thorough physical examination. Alzheimer’s is generally suspected when there is a gradual deterioration in mental ability. The doctor will perform tests, such as blood tests and brain scans, to rule out other possible causes of the symptoms. The doctor will also ask the patient a series of questions to test his or her mental status. One type of test of mental status is called neuropsychological testing, which is a standardized test of memory, concentration, and visual-spatial skills. Because a definite diagnosis can only be made by performing an autopsy after death, patients are diagnosed with “probable” Alzheimer’s. An autopsy of brain tissue, however, will show areas of abnormal tissue, called plaques, made up of abnormal proteins; a loss of nerve cells; and areas of tangles in the nerve cells that remain in patient’s with Alzheimer’s disease.

What is the treatment?

At this time, there is no cure for Alzheimer’s disease. Treatment focuses on maintaining the best possible quality of life for the patient by providing a supportive environment. Memory aids, such as calendars and other daily reminders of time and place, can help the patient feel more secure and reduce confusion. There are some medications that, when used in the early stages of this disease, can slow memory loss in some patients for a limited amount of time. However, these drugs are used with caution because of potential side effects. Other drugs may be prescribed to treat anxiety, sleeplessness, depression, and hallucinations, as necessary. In the early stages of Alzheimer’s, it is important to help the patient maintain as much independence as possible. As the disease progresses, it may be necessary to seek the help of a home healthcare aid, an adult daycare, or nursing home. While there is currently no treatment to prevent or stop the progression of Alzheimer’s, researchers are continuing to study this disease and test new drugs. There is a possibility that certain types of nonsteroidal anti-inflammatory drugs (NSAIDs) may slow the progression of Alzheimer’s.

Self-care tips
A diagnosis of probable Alzheimer’s is devastating for someone who has been accustomed to living an independent life. It is important to provide the patient with emotional and physical support as he or she adjusts to living with this disease. Keeping the daily routine consistent and as stress free as possible is helpful. Because depression is so common in the early stages of Alzheimer’s, you should be aware of the signs of depression and seek help for the patient as soon as possible. Caring for someone with Alzheimer’s can be demanding and discouraging, especially when the loved one does not remember who you are. Your doctor or local social services agency can direct you to support services to help make this time a little easier. Also seek legal advice so it is clear who has the power to make medical and financial decisions once your loved one is no longer able to do this for him or herself. If you have a family history of Alzheimer’s disease, see your doctor for regular checkups. An early diagnosis is important, especially as the medical community learns more about this disease and its treatment. While there is no way to prevent this disease, you can lower your risk and protect yourself from many illnesses by following a healthy diet that is high in fiber and antioxidants and low in saturated fat, and participating in regular physical exercise. Performing activities that stimulate your brain on a regular basis, such as crossword puzzles, word searches, or memory games, may also help maintain mental ability longer.

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.

Self-care tips

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.
